i Safety Warnings • This symbol denotes an important safety tip or SHOCK HAZARD AVOID HEAT KEE DR OID ATION warning. Please read these instructions carefully before performing any of the procedures contained in this manual. • DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a qualified electrical technician install, adjust and service this equipment.
ii General Information The LEESON FHP Series Drives are solid state, variablefrequency AC motor drives. The FHP Series utilizes a 115 or 230 VAC, 50/60 Hz, single-phase input, and is factory calibrated for an output of 0 to 60 Hz. They will operate any 1.5 HP or smaller, 208/230-volt threephase-AC-induction, single-phase permanent split capacitor motor (see page v) and can be user calibrated for 0 through 120 Hz output.
General Information iii Many 3-phase inverter manufacturers claim that they can run single-phase motors effectively. This is normally accomplished by wiring only 2 phases; however, this method may cause instabilities due to the lack of feedback from one of the motor connections. Furthermore, motor torque will be reduced considerably because the phases are 120° apart. Although the FHP Series uses this method of connection, its fundamental design enables it to operate efficiently under these conditions.

5 Installation Warning DO NOT install, rewire, or remove this control with input power applied. Failure to heed this warning may result in fire, explosion, or serious injury. Circuit potentials are at 115 or 230 VAC above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements. Do not disconnect any of the motor leads from the drive unless power is removed. Opening any one motor lead may damage the drive.
6 Mounting Warning DO NOT install, rewire, or remove this control with input power applied. Doing so may cause fire or serious injury. Make sure that you read and understand the Safety Warnings before attempting installation. NOTE: Horizontal mounting may require derating the drive. See your LEESON representative for more information • It is recommended that the drive be oriented with the chassis vertical for best heat dissipation.
7 • Protect the drive from dirt, moisture, and accidental contact. Provide sufficient room for access to the terminal block and calibration trimpots. • Mount the drive away from the heat sources. Operate the drive within the specified ambient operating temperature range. • Prevent loose connections by avoiding excessive vibration of the drive. • The chassis must be earth grounded.
8 Wiring Warning 쇵 DO NOT install, rewire, or remove this control with input power applied. Failure to heed this warning may result in fire, explosion, or serious injury. Circuit potentials are at 115 or 230 VAC above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements. Do not disconnect any of the motor leads from the drive unless power is removed. Opening any one motor lead may damage the drive.
9 Shielding guidelines Warning Under no circumstances should power and logic leads be bundled together. Induced voltage can cause unpredictable behavior in any electronic device, including motor controls. As a general rule, LEESON recommends shielding of all conductors. If it is not practical to shield power conductors, LEESON recommends shielding all logic-level leads. If shielding the logic leads is not practical, the user should twist all logic leads with themselves to minimize induced noise.
10 If the drive continues to pick up noise after grounding the shield, it may be necessary to add AC line filtering devices, or to mount the drive in a less noisy environment. Logic wires from other input devices, such as motion controllers and PLL velocity controllers, must be separated from power lines in the same manner as the logic I/O on this drive. Heat sinking The 175326.00 drive is delivered with a heat sink chassis.
11 Fusing FHP series drives include AC power line fuses on the main PC Board. Use fast-acting fuses rated for 250 VAC or higher. See Table 1 for recommended line fuse sizes. Table 1. Line Fusing Chart Drive 175326.
12 Connections All power input and power output connections are made to TB502. Warning DO NOT connect this equipment with power applied. Failure to heed this directive may result in fire or serious injury. LEESON strongly recommends the installation of a master power switch in the voltage input line. The switch contacts should be rated at a minimum of 200% of motor nameplate current and 250 volts. Input AC Power connections Connect the AC power input to TB502 L1 and L2 as shown in Figure 5 (page 13).
13 Figure 5. AC Line Connections for 175326.
14 Warning Ꮨ Do not connect 230 VAC line input when the drive is set for 115 VAC input. This will result in severe damage to the motor. and can lead to explosion and/or injury. Connect AC Power input to L1 and L2 as shown in Figures 5 (page 13), depending on the model of drive being used. NOTE: The 175326.00 drive is equipped with a voltagedoubler feature, which converts a 115 VAC input to a 230 VAC output, for use with 230V motors.
15 NOTE: The FHP series of drives covered in this manual are meant to be used with 208/230 VAC motors only. DO NOT use this series of drives with 115 VAC motors. JMP502 Jumper Pins 1 & 2 for 115 VAC input Jumper Pins 2 & 3 for 230 VAC input JMP501 Jumper Pins 2 & 3 for 115 VAC input Jumper Pins 1 & 2 for 230 VAC input Figure 6. Voltage Doubler Feature for 175326.
16 Motor connections Motor connections are made to TB502 Single-phase operation For single-phase operation, connect the motor as shown below in Figure 7. Ensure that the prewired capacitor and its associated motor coil are connected to terminals U and V as shown. This connection may be internal if using a 2wire motor. If the motor has three leads, you must make this connection yourself. To reverse a single phase permanent split capacitor motor, connect the motor as shown in Figure 8 (page 17).
17 NOTE Motor run cap must be removed from the circuit. This method works with most (but not all) motors. Figure 8. Single Phase Operation (Reversing) Three-phase operation Connect a three-phase motor to terminals U, V and W as shown in Figure 9 below. Figure 9.
18 Speed Adjust Potentiometer Connections Set JMP504 for VDC input by jumpering pins 1 & 2. Set JMP505 for 0-5VDC by jumpering pin column 1. Refer to Figure 4 (page 4) for Jumper Locations. Connect a speed adjust potentiometer to terminals S1, S2 and S3. Make sure the potentiometer is connected so that the motor speed will increase as the potentiometer is turned clockwise. See Figure 10 below. NOTE: These settings and connections are factory installed on the 175326.00 drive.
19 Signal and Optional Switch Connections All signal and switch connections are made at TB501. Use 20 - 24 AWG wire for speed adjust potentiometer and switch connections. NOTE: The Enable/Disable and Direction switch are factory installed on the FHP Series drive. ENABLE/DISABLE switch Connect a single-pole, single-throw ENABLE/DISABLE switch between the ENABLE (E2) and COMMON (E1) terminals as shown. Open the switch to disable the drive and coast or brake to a stop. Refer to (page 26) for stopping method.
20 ENABLE/DISABLE SWITCH (open to disable) DIRECTION SWITCH D S3 S2 S1 E1 E2 Figure 11. Signal and Optional Switch Connections for 175326.00 Voltage or Current Follower Drives can be configured to follow an isolated or a grounded (non-isolated) voltage or current signal. To configure the drive to follow a voltage or current signal, connect the signal leads to the S1 and S2 terminals on TB501 as shown in Figure 11 above.
21 JMP504 Input Type Jumper pins 1 & 2 for Voltage follower or speed pot mode. Jumper pins 2 & 3 for Current follower. JMP505 Input Range Settings Set jumper in position 1 for 0-5 VDC signal or speed pot input. Set jumper in position 2 for 0-10 VDC signal. Set jumper in position 3 for 4-20 mA signal. * * The 4-20 mA ZERO SET potentiometer should be used to calibrate the zero (or minimum) speed of the drive with 4mA applied to the input. For voltage inputs this pot should be set to full CCW.
22 Operation Warning 쇵 Dangerous voltages exist on the drive when it is powered, and up to 60 seconds after power is removed and the motor stops. BE ALERT. High voltages can cause serious or fatal injury. Do not change jumper settings with power applied. Ensure that jumper settings are compatible with the motor being controlled. Voltage Input Warning 쇵 DO NOT connect 230 VAC line input when the drive is set for 115 VAC input.
23 Voltage Doubler Warning DO NOT connect 230 VAC line input when drive is set for 115 VAC input. This will result in severe damage to the motor and drive, and possible explosion or severe injury. The 175326.00 series drives are equipped with a unique voltage-doubling feature, for use when 230 VAC input voltage is not available. This feature converts a 115 VAC input to a 230 VAC output, for use with 230V motors. The drive output current rating remains the same for either AC input voltage.
24 Startup Warning DO NOT change jumper settings with power applied. Ensure that jumper settings are compatible with the motor being controlled. Before applying power, verify that no conductive material is present on the printed circuit board. 1. Verify that no conductive material is present on the PCB. 2. Verify that the correct voltage is connected to the inputs before applying power. DO NOT CONNECT 230 VAC line voltage to a 115 VAC configured drive.
25 7. If you attempt to startup and the yellow TQ LED comes on, the control has entered torque limit mode. To avoid this occurrence, you may: a. increase the torque limit setting*, or b. lengthen the acceleration time enough to accommodate the starting torque needed by adjusting the ACCEL trimpot. * Do not set the torque limit setting above 150% of the motor’s nameplate current rating.
26 Starting and stopping methods (factory set to COAST position) To coast the motor to a stop Insure that JMP506 is set to the COAST position as shown in Figure 13 (page 27). Refer to Figure 4 (page 4) for Jumper Locations. To coast the motor to a stop open the ENABLE/DISABLE switch, or remove the jumper between ENABLE (E2) and COMMON (E1) terminals of TB501. Refer to (page 19) for instructions on switch installation.
27 1 2 3 BRAKE COAST JMP506 (on top board) Jumper Pins 1 & 2 to Brake Jumper Pins 2 & 3 to Coast Figure 13. 175326.00 Jumper Settings--JMP506 Thermal protection of the motor The enable input can also act as a motor thermal protection circuit for motors having a built-in thermal protector. These thermal protectors are operated only by motor heat and open the enable circuit when the motor reaches a temperature capable of causing damage to the motor winding.
28 Normally, these thermal procedures automatically close the circuit when the motor has cooled to a safe temperature. In operation, the drive can be disabled by opening the enable switch or opening the thermal overload switch. See Figure 14 below. ENABLE / DISABLE SWITCH CLOSE TO ENABLE THERMAL OVERLOAD SWITCH TB501 E2 (ENABLE) E1 (COMMON) Figure 14.
29 Line starting and line stopping Warning LEESON strongly recommends the installation of a master power switch in the voltage input line (see Power and Fuse connections, page 11). The switch contacts should be rated at a minimum of 200% of motor nameplate current and 250 volts. Line starting/line stopping (applying and removing AC voltage input) may be configured to operate two different ways by use of JMP503.
30 When JMP503 is set to the RESTART position as shown in Figure 15 below (factory set to UV trip), the drive will stop when an under voltage condition, (bus voltage drops below 200 VDC), occurs. This can occur due to line sag, line transients, or line disconnect. A timer, (1.5 seconds), is started which allows an automatic restart if the bus voltage has returned to proper operation potential. Refer to Figure 4 (page 4) for Jumper Locations.
31 Calibration Warning 쇵 Dangerous voltages exist on the drive when it is powered, and up to 60 seconds after power is removed and the motor stops. When possible, disconnect the voltage input from the drive before adjusting the trimpots. If the trimpots must be adjusted with power applied, use insulated tools and the appropriate personal protection equipment. BE ALERT. High voltages can cause serious or fatal injury. The 175326.00 has ten user-adjustable trimpots.

33 Calibration Procedure Setup for 60 Hz Motors: 1. Set JMP501 & JMP502** to appropriate input voltage setting (115/230VAC). Refer to Figure 4 (page 4) for Jumper Locations. 2. Set the ENABLE switch to the DISABLE (open) position. If no switch is installed, remove the jumper between the (E2) and (E1) terminals of TB501. 3. Set the DIRECTION switch to the FWD (open) position. If no switch is installed, confirm that there is no jumper between the (D) and (E1) terminals of TB501. 4.
34 MINIMUM SPEED (MIN) Rotate the speed adjust potentiometer CCW or set the signal reference to a minimum. Adjust the MIN trimpot until the motor has stopped (for zero speed setting), or until desired minimum speed has been reached. TORQUE LIMIT (TQ LIMIT) Warning Although the TORQUE LIMIT trimpot can be set up to 150% of the drive nameplate rating, continuous operation beyond the drive nameplate rating may cause damage to the motor and/or drive. 1.
35 7. Set the speed adjust potentiometer or reference signal to zero speed. 8. Remove power from the drive. 9. Remove the lock from the motor shaft. 10. Remove the ammeter in series with the motor lead. ACCELERATION (ACCEL) 1. Set the speed adjust potentiometer or reference signal to zero and wait for the motor to come to a stop (or minimum speed). 2. Set the speed adjust potentiometer or reference signal to maximum speed (full CW) and note the time the motor takes to accelerate to maximum speed. 3.
36 2. Set the speed adjust potentiometer or reference signal to minimum speed (full CCW) and note the time the motor takes to decelerate to minimum speed. 3. If the deceleration time differs from the desired time, adjust the DECEL trimpot until the desired time is reached. Rotating the DECEL pot CW increases the deceleration time. BOOST The BOOST trimpot is used to increase motor torque at low speeds. The minimum setting is sufficient for most applications and does not need to be adjusted.
37 SLIP COMPENSATION (SLIP COMP) Slip compensation is used to minimize the normal speed changes occurring in an induction motor from no load to full load conditions. 1. Using the speed adjust potentiometer or reference signal, run the motor at the desired RPM under a no load condition. Measure the RPM with a tachometer. 2.
38 Application Notes Independent adjustable speeds with DIR switch Replace the speed adjust potentiometer with two singlepole multi-position switches, and two or more potentiometers in parallel, with a total parallel resistance of 10K ohms. Figure 17 below shows the connection of two independent speed adjust potentiometers that can be mounted at two separate operating stations. TB501 E2 FORWARD SPEED 20K OHM E1 REVERSE SPEED S1 20K OHM S2 S3 FORWARD REVERSE D (DIRECTION) Figure 17.
39 RUN/JOG switch Using a RUN/JOG switch is recommended in applications where quick stopping is not needed and frequent jogging is required. Use a single-pole, two-position switch for the RUN/JOG switch, and a single-pole, normally open, momentary operated pushbutton for the JOG pushbutton. Connect the RUN/JOG switch and JOG pushbutton to terminal board TB501 as shown in Figure 18 below. The motor stops when the RUN/JOG switch is set to JOG. Press the JOG pushbutton to jog the motor.
40 Single speed potentiometer control of multiple motors Warning The combined current draw of all motors must not exceed the current rating of the drive. The 175326.00 is capable of operating up to eight 3-phase motors simultaneously. All motors must be of the same type and must control similar loads. Connect each motor as shown in Figure 19 below. MOTOR A U CW V MOTOR B W S3 S2 S1 10K OHM SPEED ADJUST POTENTIOMETER FHP SERIES DRIVE Figure 19.
41 Quick Reversing To reverse the direction of motor shaft rotation, install a DPDT center off switch as shown in Figure 20 below. The drive will stop the motor before reversing, so there is no need to wait for the motor to coast to a stop before changing direction. JMP506 must be set to brake. Refer to Figure 4 (page 4) for Jumper Locations. TB501 E2 (ENABLE) DPDT CENTER OFF SWITCH E1 (COMMON) FWD STOP REV S1 S2 S3 D Figure 20.
42 Troubleshooting Warning 쇵 Dangerous voltages exist on the drive when it is powered, and up to 60 seconds after power is removed and the motor stops. When possible, disconnect the voltage input from the drive while troubleshooting. BE ALERT. High voltages can cause serious or fatal injury. Before troubleshooting Perform the following steps before starting any procedure in this section: • Disconnect AC voltage input from the drive. Wait 60 seconds for power to discharge.
43 • Verify that there are no short circuits or grounded connections. • Check that the drive’s rated phase current and RMS voltage are consistent with the motor ratings.
44 Diagnostic LEDs The 175326.00 is equipped with diagnostic LED's to assist the user in troubleshooting and monitoring equipment status while in use. Refer to Figure 21 (page 45) for diagnostic LED locations. POWER LED The green POWER LED is on when AC line voltage is applied and the control’s low-voltage power supply is operational. ENABLE LED The red ENABLE LED turns on whenever the inverter output is enabled.
45 TORQUE (TQ) LIMIT LED The yellow TQ LIMIT LED is on when the drive output current exceeds the threshold set by the TQ LIMIT trimpot. When the TQ LIMIT LED turns on, shut down the motor and drive by disabling or removing power. Check the motor to make sure it is not jammed or overloaded. The TQ LIMIT trimpot may need to be recalibrated. See the Calibration section (page 34) for information on calibrating the TQ LIMIT trimpot.
46 Problem Internal line fuse blows Internal line fuse does not blow, but the motor does not run Possible Cause Suggested Solution 1. Line fuses are the wrong size. 1. Check that line fuses are properly sized for the motor being used. 2. Motor or motor cable is shorted to ground. 2. Check motor cable and motor for shorts. 3. Nuisance tripping caused by a combination of ambient conditions and high-current spikes (i.e. reversing). 3.
47 Problem Internal line fuse does not blow, but the motor does not run (cont.) Motor runs too slow or too fast at set speed Possible Cause Suggested Solution 3. Drive is “tripped” off or has gone into thermal overload. 3. Disable, then reenable the drive. 4. Drive has been disabled. 4. Ensure that ENABLE (EN) and COM terminals are properly connected. 5. Drive is in current limit. 5. Verify that motor is not jammed. Increase TQLIM setting if it is set too low (page 34). 6.
48 Problem Motor will not reach the desired speed Possible Cause Suggested Solution 1. MAX SPD setting is too low. 1. Increase MAX SPD setting (page 33). 2. Nominal input voltage may be too low for motor 2. Compare motor voltage to input voltage; replace motor if necessary 3. Motor is overloaded. 3. Check motor load. Resize the motor or drive if necessary. Motor pulsates or surges under load 1. Motor “bouncing” in and out of torque limit. 1.
49 Problem TQ is unsatisfactory at high speeds. Possible Cause Suggested Solution 1. TQ LIMIT set too low. 1. Check TQ LIM setting (page 34). 2. Load may exceed rating of motor/drive. 2. “Fix” load (i.e., straighten mounting, coupling, etc.); or replace motor and drive with motor and drive rated for higher horsepower. 3. Nominal input voltage may be too low for motor. 3. Compare motor voltage to input voltage. Replace motor if necessary.
50 Optional Capacitor Kit (175325.00) In some applications, lowering carrier frequency reduces switching losses and increases bearing life in some motors. LEESON provides an optional capacitor kit for lowering the carrier frequency. The default carrier frequency on FHP Series controls is 16kHz. Using one of the capacitors supplied in the kit, the carrier frequency can be lowered to a range of 12kHz to 4kHz. Note: Audible noise will increase when the carrier frequency is lowered.
51 Insert the 2-pins of the carrier frequency capacitor into the 2 socket holes (C503) located on board. Cap Label 3n3 J100 TORQUE LIMIT JMP504 C503 INPUT SELECT 1-2 = VDC 2-3 = mA JMP505 RANGE SELECT 1 = 0 - 5 VDC 2 = 0 - 10 VDC 3 = 4 - 20 mA Figure 22. 175325.
