6.0 THEORY 6.1 DESCRIPTION OF AC MOTOR OPERATION Three phase AC motors are comprised of two major components, the stator and the rotor. The stator is a set of three electrical windings held stationary in the motor housing. The rotor is a metal cylinder, fixed to the motor drive shaft, which rotates within the stator. The arrangement of the stator coils and the presence of three phase AC voltage give rise to a rotating magnetic field which drives the rotor.
If the frequency applied to the motor is increased while the voltage remains constant, torque capability will decrease as speed increases. This will cause the horsepower capability of the motor to remain approximately constant. Motors run in this mode when operated above base speed, where drive output voltage is limited by the input line voltage. This operating range is known as the “constant horsepower” range. The typical maximum range for constant horsepower is about 2.3 to 1 (60 to 140 Hz).
“Variable torque” refers to the fact that the torque required varies with the square of the speed. Also, the horsepower required varies with the cube of the speed, resulting in a large reduction in horsepower for even a small reduction in speed. It is easily seen that substantial energy savings can be achieved by reducing the speed of a fan or pump. For example, reducing the speed to 50% results in a 50 HP motor having to produce only 12.5% of rated horsepower, or 6.25 HP.
6.2.3 MICRO SERIES INPUTS AND OUTPUTS The drive has two analog inputs (0-10 VDC and 4-20 mA) that can be used for speed reference, PID set point reference, or PID feedback. A speed potentiometer (10,000 Ohm) can be used with the 0-10 VDC input. There are also two analog outputs: one is proportional to speed (frequency), and the other is proportional to load. The drive has three programmable outputs for status indication: one Form C relay and two open-collector outputs. Refer to Sections 14.
The following describes the possible relay output settings: NONE This setting disables the relay output. RUN The relay energizes when the drive is given a START command, and remains energized until: a STOP command is given and the output frequency has decelerated to 0.5 Hz, the drive has “tripped”, or the input voltage is removed. Note that this relay indicates only that the drive is in the RUN mode. It does not necessarily indicate that the motor is turning.
7.0 INSTALLATION WARNING DRIVES MUST NOT BE INSTALLED WHERE SUBJECTED TO ADVERSE ENVIRONMENTAL CONDITIONS! DRIVES MUST NOT BE INSTALLED WHERE SUBJECTED TO: COMBUSTIBLE, OILY, OR HAZARDOUS VAPORS OR DUST; EXCESSIVE MOISTURE OR DIRT; STRONG VIBRATION; EXCESSIVE AMBIENT TEMPERATURES. CONSULT LEESON FOR MORE INFORMATION ON THE SUITABILITY OF A DRIVE TO A PARTICULAR ENVIRONMENT. The drive should be mounted on a smooth vertical surface capable of safely supporting the unit without vibrating.
7.1 INSTALLATION AFTER A LONG PERIOD OF STORAGE WARNING Severe damage to the drive can result if it is operated after a long period of storage or inactivity without reforming the DC bus capacitors! If input power has not been applied to the drive for a period of time exceeding 6 months (due to storage, etc), the electrolytic DC bus capacitors within the drive can change internally, resulting in excessive leakage current.
8.0 INPUT AC REQUIREMENTS WARNING Hazard of electrical shock. Disconnect incoming power and wait three minutes before servicing the drive. Capacitors retain charge after power is removed. 8.1 INPUT AC POWER REQUIREMENTS 8.1.1 VOLTAGE: The input voltage must match the drive’s nameplate voltage rating. Voltage fluctuation must not vary by greater than 10% overvoltage or 15% undervoltage.
9.0 VOLTAGE SELECTION 9.1 INPUT VOLTAGE RATINGS 115/230 Volt MICRO Series drives are rated for 240/120 Vac, 50-60 Hz input. The drive will function with input voltage of 120 Vac (+10%, -15%) at 48 to 62 Hz when wired for 120 Vac input, or with input voltage of 240 Vac (+10%, - 15%), at 48 to 62 Hz, when wired for 240 Vac input. 230 Volt MICRO Series drives are rated for 240/200 Vac, 50-60 Hz input. The drive will function with input voltages of 200 to 240 Vac (+10%, -15%), at 48 to 62 Hz.

Severe damage to the drive will result. INSTALL, WIRE, AND GROUND IN ACCORDANCE WITH ALL APPLICABLE CODES. NOTES: 1. Wire the motor for the proper voltage per the output rating of the drive.
12.0 INITIAL POWER UP WARNING Hazard of electrical shock. Disconnect incoming power and wait three minutes before servicing the drive. Capacitors retain charge after power is removed. Before attempting to operate the drive, motor, and driven equipment be sure all procedures pertaining to installation and wiring have been properly followed.
3. If the motor is rotating in the wrong direction, press the “STOP” key, remove power from the drive, wait three minutes for the bus capacitors to discharge, and swap any two of the motor wires connected to T1, T2, and T3. NOTE 1: The drive is phase insensitive with respect to incoming line voltage. Therefore, to change the motor rotation, the phases must be swapped at the drive output terminals or at the motor.
13.2 MICRO SERIES DISPLAY The following describes the possible display configurations for the SPEEDMASTER MICRO Series drive. 13.2.1 MICRO SERIES DISPLAY IN STOP MODE When the drive is in the STOP mode, there are three possible delays. The first is the SPEED display, which looks like this: NOTE: See Parameter 31 - HZ UNITS for the SPEED UNITS display options. Pressing the ENTER key will change the display from the SPEED indication to the % LOAD indication.
The following table shows the possible DRIVE STATUS indications that can appear on the drive display: DRIVE STATUS TABLE DISPLAY DESCRIPTION STOP Drive is in STOP mode - No output to the motor. RUN Drive is in RUN mode and is within +/- 3 Hz of the speed set point. FAULT Drive has shut down due to a FAULT condition. If the fault condition has passed, pressing the STOP key will clear the fault and return the drive to the STOP mode.
13.2.2 MICRO SERIES DISPLAY IN RUN MODE When the drive is in the RUN mode, the default display will look like this: As in the STOP mode, the ENTER key can be used to toggle the display from SPEED to % LOAD to VAC (motor voltage): NOTE: During acceleration and deceleration to the SPEED set point, the DRIVE STATUS will show the actual drive speed. When the SPEED set point is reached, the DRIVE STATUS will change to RUN (or STOP if the drive is decelerating to a STOP).
13.2.3 MICRO SERIES DISPLAY IN FAULT MODE When the drive trips on a fault, the display will automatically change to the FAULT display, which indicates the FAULT MESSAGE: In FAULT mode, the ENTER key will toggle the display between four screens: FAULT, SPEED, % LOAD and VAC. The DRIVE STATUS for these displays will be FAULT. An example is shown below of the drive in the FAULT mode displaying SPEED.
The table below shows the possible SPEED REFERENCE SOURCE indications for the auxiliary status display: SPEED REFERENCE TABLE DISPLAY KEY DESCRIPTION KEYPAD - UP and DOWN arrow keys VDC 0 - 10 VDC analog input at TB-5A IDC 4 - 20 mA analog input at TB-5B SP#1 PRESET SPEED #1 SP#2 PRESET SPEED #2 SP#3 PRESET SPEED #3 SP#4 PRESET SPEED #4 JOG MOP JOG SPEED (In JOG mode, JOG SPEED - PRESET SPEED #2) “MOTOR OPERATED POT” – Change speed using contact closures at TB-13A (DEC FREQ
14.0 CONTROL WIRING 14.1 GENERAL 14.1.1 KEYPAD CONTROL The drive can be controlled by the keypad or by control devices wired to the terminal strip. The drive will run from the keypad “out of the box”, requiring no connections to the terminal strip. Refer to Section 13.0 - KEYPAD CONTROL. 14.1.2 CONTROL WIRING VS. POWER WIRING External control wiring MUST be run in a separate conduit away from all other input and output power wiring.
14.2 START/STOP AND SPEED CONTROL 14.2.1 REMOTE MODE SELECTION The REMOTE mode can be selected by one of two methods: 1. Program Parameter 30 - CONTROL to REMOTE, or: 2. Program CONTROL to BOTH, set the TB-13A or TB-13C function (see Parameter 47 or 49) to LOCAL SELECT, and DO NOT make a contact closure between TB-13A or TB-13C and TB-2 (making the contact closure will select LOCAL mode).
14.2.3 ALTERNATE TWO-WIRE START/STOP CONTROL METHOD WARNING This method requires TB-13C to be set for RUN REVERSE, which will disable TB-1 as a STOP switch! Incorrect use of TB-1 may result in damage to equipment and/or injury to personnel! Refer to Parameter 49 - TB-13C. FORWARD ROTATION ONLY 1. Select REMOTE mode (see 14.2.1). 2. Program Parameter 27 - ROTATION to FWD & REV. 3. Program Parameter 49 - TB13C to START REVERSE. This will force TB-12A to act as RUN FORWARD. 4.
14.2.4 THREE-WIRE START/STOP CONTROL A three-wire start/stop circuit can be accomplished by one of two methods on the MICRO Series drive. Follow the appropriate procedure listed below: FORWARD ROTATION ONLY 1. Select REMOTE mode (see 14.2.1). 2. Wire a normally closed momentary STOP contact between TB-1 and TB-2. Momentarily open this contact to STOP the drive. 3. Wire a normally open momentary START contact between TB-12A and TB-2. Momentarily close this contact to START the drive.
14.2.5 SPEED REFERENCE SIGNALS The drive allows for three analog speed reference inputs: a speed potentiometer (10,000 Ohm), 0-10 VDC, or 4-20 mA. SPEED POT Connect the wiper to terminal TB-5A, and connect the high and low end leads to terminals TB-6 and TB-2, respectively. 0-10 VDC Wire the positive to terminal TB-5A and the negative to terminal TB-2. TB-5A input impedance is 200 kilohms. 4-20 mA Wire the positive to terminal TB-5B and the negative to terminal TB-2. TB-5B input impedance is 100 ohms.
JOG The JOG function only works when the drive is in REMOTE mode, and only when the drive is in a STOP condition. TB-13B can be programmed for either JOG FORWARD or JOG REVERSE. The jog speed is set by PRESET SPEED #2. Close TB-13B to TB-2 to JOG, and open the contact to STOP. WARNING When operating in JOG mode, the STOP key WILL NOT stop the drive. To stop the drive, the contact between TB-13B and TB-2 must be opened.

18.0 DESCRIPTION OF PARAMETERS 0 LINE VOLTS (LINE VOLTAGE) This parameter calibrates the drive for the correct input voltage, and can be set to AUTO, HIGH, or LOW. When set to AUTO, the drive measures the DC bus voltage when power is applied and automatically calibrates itself according to the measured value (DC bus voltage is equal to input voltage multiplied by 1.4). This parameter can also be set “manually”, using the HIGH or LOW settings.
1-4 SPEED #1-#4 (PRESET SPEEDS #1, #2, #3, AND #4) PRESET SPEEDS are only active when the drive is in AUTO mode, and are activated via contact closures between terminal TB-2 and terminals TB-13A, TB-13B, and TB-13C. These terminals must be programmed as preset speed selects using Parameters 47 - 49: TB13A, TB13B, and TB13C. The preset speeds can only be set to values that are within the operating range defined by the minimum and maximum frequency (see Parameters: 10 - MIN FREQ, and 11 - MAX FREQ).
Example: The critical frequency is 21 Hz, and a bandwidth of 2 Hz is desired. Therefore, set SKIP #1 to 20 Hz and set SKIP BANDWIDTH to 2 Hz. This results in a speed range from 20 Hz to 22 Hz that the drive will not operate within continuously. If the drive were operating at 25 Hz and then commanded to operate at a speed within the range of avoidance, the drive would decelerate to 22 Hz and remain at that frequency until commanded to 20 Hz or below.

11 MAX FRQ (MAXIMUM FREQUENCY) This parameter defines the upper limit of the drive’s speed range. MAX FRQ is used in conjunction with MIN FRQ (Parameter 10 above) to define the operating range of the drive. WARNING 12 Consult motor manufacturer before operating motor above rated frequency. Overspeeding the motor and/or driven equipment can cause damage to equipment and injury to personnel! DC BRAKE (DC BRAKE VOLTAGE) DC braking creates a braking torque by injecting DC voltage into the motor.
14 DYN BRAK (DYNAMIC BRAKE) This parameter enables the dynamic braking circuit. Set this parameter to ON only if the optional dynamic braking circuit board and resistors are installed. Dynamic braking is used in applications where high-inertia loads need to be decelerated quickly. When this is attempted, the motor regenerates voltage back into the drive, causing the DC bus voltage to rise, eventually resulting in a HI VOLTS fault.
The “speed-compensated” thermal overload circuit offers additional protection from high load conditions at low speeds, where motor cooling is often less effective (e.g., motors with shaft-mounted fans). As seen on the diagram below, the drive reduces the allowable continuous output current when operating at frequencies less than 30 Hz. Example 2: A 480 Vac, 20 HP drive is operating a motor at 10 Hz. From the diagram, a drive operating at 10 Hz can deliver about 75% of its output current rating continuously.
18 (BASE FREQUENCY) BASE The BASE FREQUENCY determine the V/Hz ratio by setting the frequency at which the drive will output full voltage to the motor. For most applications the base frequency should be set to match the motor’s rated frequency. For example, if the drive is rated for 460 VAC output, and the BASE FREQUENCY is set to 60 Hz, the drive will maintain a constant ratio of 7.66 V/Hz (except when AC BOOST or FX BOOST are active, see Parameters 19 and 20) from 0 Hz to 60 Hz.
20 (AC BOOST) AC BOOST AC BOOST is similar to FX BOOST, but is only active when the drive is accelerating. During acceleration, the output voltage is increased according to the setting of AC BOOST, which increases motor torque. Refer to the diagram below. AC BOOST, like FX BOOST, is used in applications with high-inertia loads. The diagram below illustrates how FX BOOST and AC BOOST alter the V/Hz ratio to increase motor torque.
22 TORQUE (TORQUE CURVE SELECTION) This parameter is used to select whether the output of the drive follows a constant or variable V/Hz curve. The following selections are available: CONSTANT Use for constant torque applications to optimize torque. VARIABLE Use for variable torque applications to optimize energy savings. CT/NOCMP Use for constant torque applications that require full overload capacity at low speeds (see Parameter 17 - MOTOR OL).
25 WARNING START (START MODE) Automatic start of equipment may result in damage to equipment and/or injury to personnel! Automatic start should only be used on equipment that is inaccessible to personnel. This parameter selects the starting method for the drive, and can be set for one of the following: NORMAL The drive will start when the appropriate contact closure is made on the terminal strip (in REMOTE mode), or by pressing the keypad START key (in LOCAL mode).
27 WARNING ROTATION (ROTATION DIRECTION) If TB-13C is programmed for RUN REVERSE, TB-1 is disabled and CANNOT be used as a STOP switch! This is true in LOCAL and REMOTE mode. Incorrect use of TB-1 may result in damage to equipment and/or injury to personnel! Refer to Parameter 49 - TB13C for more information. This parameter is used to limit the motor rotation direction to forward or reverse, or to allow rotation in both directions.
29 MANUAL (MANUAL) This parameter selects the speed reference source when the drive is set for MANUAL speed control (see parameter 28 - AUTO/MAN above). The speed reference options are KEYPAD (UP and DOWN ARROW keys), or 0 - 10 VDC (from a speed pot wired to TB-2, 5A, and 6; or some other 0-10 VDC source).
33 SPEED DP (SPEED DECIMAL POINT) This parameter is used to move the decimal point location in the speed display. This parameter will not have any effect if UNITS is set to HERTZ or % HZ. The possible settings are: XXXXX, XXX.X, XX.XX, X.XXX, and .XXXX. Refer to Parameter 32 - HZ MULT above for an example on the use of SPEED DP. 34 LOAD MLT (LOAD MULTIPLIER) This parameter is used to scale the % LOAD display.
Example: SLEEP THRESHOLD is set to 15 Hz and SLEEP DELAY is set to 60 seconds. If the drive operates below 15 Hz for 60 seconds, the drive will “go to sleep” and the motor will stop. The drive’s display will indicate SLEEP, and the drive will remain “sleeping” until the drive commanded to a speed equal to greater than 17 Hz. At this point, the drive will “wake up” and ramp the motor up to the commanded speed.
41 AIN FLTR (ANALOG INPUT FILTER) This parameter adjusts the filter on the analog input terminals (TB-5A and TB-5B) to reduce the effect of any electrical noise that may be present on the analog input signals. This filter works in both PID mode and standard speed control mode. It should be set to the lowest value that yields acceptable performance, as setting it too high may cause the drive to react too slowly to signal changes.
47 TB13A (TB-13A INPUT FUNCTION) This parameter is used to select the function of terminal TB-13A. Closing TB-13A to TB-2 activates the TB-13A input function. The following functions can be selected: NONE Disables the TB-13A function. 0-10VDC Selects 0-10 VDC as the AUTO speed reference input. The 0-10 VDC signal is wired to TB-5A and TB-2. 4-20 MA Selects 4-20 mA as the AUTO speed reference input. The 4-20 mA signal is wired to TB-5B and TB-2.
49 WARNING TB13C (TB-13C INPUT FUNCTION) If TB-13C is programmed for RUN REVERSE, TB-1 is disabled and CANNOT be used as a STOP switch! This is true in LOCAL and REMOTE mode. Incorrect use of TB-1 may result in damage to equipment and/or injury to personnel! This parameter is used to select the function of terminal TB-13C. Closing TB- 13C to TB-2 activates the TB-13C input function. The following functions can be selected. NONE Disables the TB-13C function.
50 WARNING (TB-13D FUNCTION) TB13D STOP (TB-1) and EXTERNAL FAULT (TB-13D) circuitry may be disabled if parameters are reset to factory defaults! The drive must be reprogrammed after a RESET in order to insure proper operation (see Parameter 65 - PROGRAM). FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT AND/OR INJURY TO PERSONNEL! This parameter selects the function for TB-13D. EXT FAULT Sets TB-13D as a normally open EXTERNAL FAULT contact.
SPEED #3 value. See Parameter 3 - SPEED #3 in Section 18.0 - DESCRIPTION OF PARAMETERS, I LIMIT CURRENT LIMIT - The relay energizes when the drive is operating in current limit. Once the current limit relay is energized, it remains energized for a minimum of 500ms, regardless of whether the drive is still in current limit. At the end of the 500ms interval, the relay will de-energize if the drive is no longer in current limit. See Parameter 16 - CURRENT in Section 18.0 - DESCRIPTION OF PARAMETERS.
SPD = 0HZ The relay energizes when there is no output to the motor, for any reason, such as: drive is in STOP mode, drive is in RUN mode but the speed command is 0 Hz, drive is in SLEEP mode, drive has tripped into a fault, etc. The open-collector output circuit is a current-sinking type rated at 30 VDC and 40 mA maximum. An external power supply (30 VDC max.) must be used to power the open-collector outputs. The drive does not have a dedicated power supply for the open-collector outputs.
NOTE 2: If a RESET command (Parameter 65 - PROGRAM) is issued through the serial link, this parameter will not default back to DISABLE. However, explicitly setting this parameter to DISABLE through the serial link will cut off communication with the drive. If developing an application for serial communications, refer to the RS-232/RS-485 Modbus® Communications Protocol Specification.
65 PROGRAM (PROGRAM FACTORY DEFAULTS) STOP (TB-1) and EXTERNAL FAULT (TB-13D) circuitry may be disabled if parameters are reset to factory defaults! The drive must be reprogrammed after a RESET in order to insure proper operation. WARNING FAILURE TO DO SO MAY RESULT IN DAMAGE TO EQUIPMENT AND/OR INJURY TO PERSONNEL! This parameter is used to reset the programmable parameters back to the factory default settings.
70 PID MODE (PID MODE SELECT) This parameter activates the PID function, and selects whether the PID control will be direct or reverse acting. Refer to Section 19.0 - MICRO Series PID SET POINT CONTROL. The following options are available: OFF Disables the PID function to allow “standard” drive operation. NORMAL Enables the PID function for direct acting systems. An increase in the feedback variable will cause a decrease in motor speed. REVERSE Enables the PID function for reverse acting systems.
NOTE: If a reverse acting feedback device is being used, FB @ MIN should be set to the maximum process variable value, and FB @ MAX should be set to the minimum process variable value. 77 P GAIN (PROPORTIONAL GAIN) This parameter setting represents the speed command output (in % of maximum speed) that results from each 1% of error (1% of the feedback range; FB @ MAX minus FB @ MIN).
relay or open-collector output will de-energize, which opens the start contact and stops the drive. When the signal is equal to or greater than the MIN ALARM setting, the relay or open-collector output will energize, which closes the start contact and starts the drive. The drive must be in REMOTE mode to use the MIN/ MAX function to start and stop the drive.
19.0 MICRO SERIES PID SET POINT CONTROL PID Set point Control allows the MICRO Series Control to maintain a process set point, such as PSI or CFM, without using an external controller. When PID is activated, the MICRO Series Control will operate in a closed-loop fashion, automatically adjusting the motor speed to maintain the set point. PID set point control requires feedback from the process in order to compare the process variable “value” to the set point.
For a reverse acting transducer, set Parameter 75 - FB @ MIN to the maximum process variable feedback value, and set Parameter 76 - FB @ MAX to the minimum process variable feedback value. In other words, Parameter 75 is set higher than Parameter 76. See the example below: Example 2: A 0-100 psi transducer outputs a 20 mA signal at 0 psi and 4 mA at 100 psi. Program Parameter 75 to 100.0 PSI, and Parameter 76 to 0.
each type, so the same type of signal cannot be used for transducer feedback and set point reference. For example, a 4-20 mA signal from a transducer could not be used as a feedback signal if the set point is being controlled by a 4-20 mA signal from a PLC. 19.5 TUNING THE PID CONTROL Once the PID control is set up correctly, it needs to be tuned in order to maintain the process set point.
When the drive is in PID mode, the DRIVE STATUS portion of the display will indicate actual output frequency (in Hertz) instead of RUN, and the right side of the display will indicate PID SET POINT, % LOAD, or PID FEEDBACK. The ENTER key is used to toggle between the different displays. Examples of the possible displays are shown below: In the examples above, the drive is running at 42.53 Hz to maintain the PID SET POINT of 35.0 psi. Pressing the ENTER key displays % LOAD, which is 57%.
20.0 TROUBLESHOOTING The table below lists the fault conditions that will cause the drive to shut down, as well as some possible causes. Please contact the factory for more information on troubleshooting faults. NOTE: The drive will not automatically restart after a PWR SAG or a CONTROL fault. Also, if an OUTPUT fault occurs below 1.5 Hz, the drive will only attempt one restart, after a four minute delay. If unsuccessful, it will then trip into FAULT LOCKOUT, which will require a manual reset.
FAULT MESSAGES DESCRIPTION External fault: TB-13D is open or closed to TB-2, depending on setting of Parameter 50 - TB13D. POSSIBLE CAUSES Check setting of Parameter 50-TB13D. Check devices wired between TB13D and TB-2. DB ERROR The DB duty cycle is too high, causing the resistors to overheat. FAULT EXTERNAL Dynamic Brake fault: DB circuit has sensed a resistor overload. CONTROL Control Board fault: New software has been installed that is different from the previous version.
