DESCRIPTION OF OPERATION 5-1 Introduction The Bulletin 1557 is an adjustable speed ac drive in which motor speed control is achieved through control of the motor torque. The motor speed is measured and the torque is adjusted as required to make the measured speed equal to the speed command. The stator frequency is determined by the motor and load and the drive synchronizes itself to the motor.

DESCRIPTION OF OPERATION 5-5 Skip Speeds Four skip speeds are provided which may be used to prevent the drive from continuously operating at certain speeds, usually to avoid exciting mechanical resonance. Each of the four skip speed zones is defined by two parameters that specify its center point and width. Skip speed zones that overlap are merged. After skip speed processing, the speed command input has its sign changed if reverse rotation is selected, or is set to zero if there is no run request.

DESCRIPTION OF OPERATION 5-9 Speed Control The function of the speed control block is to determine the torque current command. The inputs are the speed reference from the speed ramp, and the stator frequency and slip frequency from the motor model. Either tach feedback is used, or the slip frequency is subtracted from the stator frequency to determine the motor speed, which is then made negative if the motor is rotating in reverse.

DESCRIPTION OF OPERATION 5-13 Flux Control for Synchronous Motor Most of the magnetization for a synchronous motor is supplied by the rotor field winding, unlike an induction motor where all of the magnetizing current is supplied through the stator. However, control of the motor flux through the field current is very slow because of the large time constant of the dc field winding and the current and voltage limitations of the field supply.
5-14 DESCRIPTION OF OPERATION Current Control The function of the current control block is to determine the firing angles of the line and machine converters. The inputs are the torque and flux producing components of the dc link current command from the speed control and flux control blocks respectively, and the dc link current and line voltage from the line converter feedback. The square root of the sum of the squares of Ix Command and Iy Command is calculated to determine the dc link current command.

After the three phase to two phase conversion described in the machine converter feedback section, the resulting stator current feedback signals (alpha and beta) are converted from analog to digital form. They are then transformed from the stationary reference frame to the rotor flux reference frame that rotates at stator frequency.

5-28 DESCRIPTION OF OPERATION Test Modes The Bulletin 1557 drive is provided with five test modes that are selected by parameter Test Mode in the Feature Select group. When Test Mode is set to the default value of zero, the drive is in the normal operating mode. If the value of this parameter is changed when the drive is running, the change will not take affect until the drive is stopped. Setting Test Mode to 1 selects the gate test mode.
DESCRIPTION OF OPERATION 5-29 Synchronous Transfer Synchronous transfer is an optional feature of the Bulletin 1557 ac drive which allows a motor to be transferred between the drive and a fixed frequency supply in either direction without stopping and with a very short interruption of power to the motor. Compared to a simple non-synchronous transfer in which power to the motor is interrupted for a significant length of time, the transient drop in motor speed is much less with synchronous transfer.
5-30 DESCRIPTION OF OPERATION Transfer to Bypass When the motor is running on the drive and a synchronous transfer to bypass is required, the transfer takes place as described below: 1. Before a transfer to bypass is requested, the drive must be given control of the open bypass contactor. Since the drive is running, it will already have control of the output contactor.
DESCRIPTION OF OPERATION 5-31 Transfer to Drive The drive must synchronize itself with the motor voltage while the motor is still running on bypass, in order to perform the transfer to drive before the motor flux decays. The output contactor must therefore be closed with the motor still connected to the line in order to pre-charge the output filter capacitors. When the motor is running on bypass and a transfer to drive is required, the transfer takes place as described below: 1.

DESCRIPTION OF OPERATION 5-33 Thyristor Diagnostics Bulletin 1557 Drive The Bulletin 1557 ac drive tests for open or shorted thyristors both when it is started and continuously while running. The method used to detect failed thyristors is different for starting and for running, but the same hardware is used in both situations.
5-34 DESCRIPTION OF OPERATION Machine Converter If no open or shorted thyristors are detected, the line converter is gated at a firing angle of 90 degrees with the machine converter gating off in order to apply a voltage to the dc link.
DESCRIPTION OF OPERATION 5-35 Thyristor Diagnostics Bulletin 1557M Mini Drive There are two differences between the Bulletin 1557M mini drive and the larger 1557 drives which affect the way thyristor failures can be detected. First, there are no thyristors connected in series, and second, there is no feedback from the gate drivers.
5-36 DESCRIPTION OF OPERATION Flying Start The 1557 drive is capable, with certain restrictions, of restarting a motor that is not stationary but is already rotating. This is a so-called flying start. In normal operation, the output of the drive is synchronized with the motor flux, which is derived from the stator voltage and current feedback.
DESCRIPTION OF OPERATION 5-37 Tachometer/Encoder Option The optional tachometer/encoder provides two significant enhancements to the drive control: 1. Provides an accurate measurement of motor speed at all times 2. Extends closed loop speed and torque control down to nearly zero speed. A pulse tachometer, also called a pulse generator or incremental encoder, produces a pulse train output with a frequency proportional to shaft speed.

9-26 COMMISSIONING Tuning Procedure The Bulletin 1557 medium voltage drive must be tuned to the motor and load to which it is connected. There are six drive functions that require tuning.
COMMISSIONING 9-27 Commutation Inductance Manual Tuning 1. Set parameter "Test mode" in “P Feature Select“ to 2 to enter dc current test mode. Current Control Parameter Screen 2. Set parameter "Idc command test" in “P Current Control” to 0.400 pu. 3. Set parameter "L commutation" in “P Current Control” to an initial value of 0.05 pu. 4. Connect an oscilloscope to the test points labeled V12 and F12 on the line converter control board.
9-28 COMMISSIONING COMMUTATION INDUCTANCE TUNED CORRECTLY COMMUTATION INDUCTANCE INCORRECTLY TUNED 10. Set parameter "Idc command test" to 0.800 pu. The dc current will increase and the commutation notches will become much larger. 11. Repeat steps 6 to 9. The higher current will produce a more accurate measurement of the commutation inductance. 12.
COMMISSIONING 3. 9-29 Start the drive. The step response of the current regulator is measured and the dc link time constant is adjusted to produce a critically damped response. This test may take up to two minutes to perform. When the desired response has been achieved the drive shuts off. The current regulator bandwidth is set back to its normal value and parameter "Autotune select" is set to zero. Parameter "Autotune Tdc" indicates the results of the test.
9-30 COMMISSIONING 9. Adjust the scope to trigger on the rising edge of the dc current reference and observe the dc current feedback on the other channel. The step response will probably have noticeable overshoot, indicating that the dc link time constant is set too low. 10. Adjust parameter "T dc link" until the current feedback rises to about 63% of its final value in 10 ms as shown in the figure. The overshoot should now be quite small. Increasing “T dc link“ causes the rise time to increase.
COMMISSIONING 3. 9-31 Commutation Inductance and Current Regulator It is possible to autotune the commutation inductance and current regulator at the same time using the following procedure: 1. Set parameter “Autotune Select” in “P Autotune” to 3. The drive will go into dc current test mode. 2. Start the drive. The commutation inductance autotuning is performed and then the current regulator autotuning is performed without stopping. When both tests are complete the drive shuts off.
9-32 5. COMMISSIONING Leakage Inductance Parameter “ L total leakage “ is used in the hardware reconstruction of the rotor flux. If this parameter is not adjusted correctly, the resulting distortion in the flux feedback may cause speed feedback or motor synchronization errors. Leakage inductance must be tuned during commissioning because it is effected not only by motor parameters but also by cable length. Leakage inductance can be measured with the motor stationary.
COMMISSIONING 6. 9-33 Flux Regulator For the flux regulator, different tuning procedures are used for induction motors and synchronous motors. Induction Motor Flux Regulator The tuning of the flux regulator for an induction motor is determined by three parameters: 1. Flxreg bandwidth in "P Flux Control" 2. L magnetizing in "P Motor Model" 3. T rotor in "P Motor Model" "Flxreg bandwidth" should be set to the default value for almost all applications.
9-34 COMMISSIONING L magn low - indicates that the measured value of magnetizing inductance is less then 1.0 pu. This warning is intended to draw attention to an unusually low value of magnetizing inductance. This may occur if the motor is much larger than the drive and the nameplate parameters do not correspond to the actual motor ratings. In this case, the measured magnetizing inductance is probably correct and parameter "L magnetizing" should manually be set equal to "Autotune Lm".
COMMISSIONING 9-35 Synchronous Motor Flux Regulator This section applies only to firmware revision 5.10 and higher. Before the flux regulator can be tuned, the analog output for the field current reference must be set up. Configuring the Field Current Reference Excitation for the synchronous motor is provided by a current regulated field supply, either a dc supply for a slip ring machine, or a three phase ac supply for a brushless machine.
9-36 COMMISSIONING Tuning the Flux Regulator The tuning of the flux regulator for a synchronous machine is determined by four parameters: 1. Flxreg bandwidth in "P Flux Control" 2. L magnetizing in "P Motor Model" 3. T rotor in "P Motor Model" 4. Lmd in “P Motor Model” "Flxreg bandwidth" should be set to the default value for almost all applications. "L magnetizing", “Lmd”, and "T rotor" are usually unknown and must be measured.
COMMISSIONING 9-37 If the flux regulator Autotuning is successful, then parameter "L magnetizing" in "P Motor Model" is set equal to "Autotune Lm", parameter "T rotor" in "P Motor Model" is set equal to "Autotune T rotor", and parameter “Lmd” in “P Motor Model” is set equal to “Autotune Lmd”. If the flux regulator autotuning fails then parameters "L magnetizing", “Lmd”, and "T rotor" are not changed and a warning is issued indicating the cause of the failure.
9-38 COMMISSIONING Reg in limit - indicates that the torque command was greater than "Torque limit motoring" or "Torque limit braking". The measured inertia value is invalid. Parameter "Autotune trq stp" or parameter "Autotune spd cmd" must be set to a lower value and the test repeated. Tuning abort - indicates that the deviation in motor speed was greater than 10 Hz. The measured inertia value is invalid. Parameter "Autotune trq stp" must be set to a lower value and the test repeated.
COMMISSIONING 9-39 CORRECTLY TUNED SPEED REGULATOR 8. Set parameter "Spdreg bandwidth" to the normal operating value. Confirm that the response time is equal to the inverse of the speed regulator bandwidth and that there is minimal overshoot. For example, if the speed regulator bandwidth is set to 2 rad/sec, the speed should rise to 63% of its final value in 0.5 second. 9. Set parameter "Speed ref step" to zero and stop the drive.
9-40 COMMISSIONING Application Setup Once the drive has been tuned, it will be necessary to configure the drive for operation in its environment. There are several parameters associated with the use of the drive for specific applications. See the Functional description in Chapter 5 for more information involving setting of the acceleration and deceleration profiles and other individual functions. Saving Parameters Save all parameters as entered into the drive E² memory.

TROUBLESHOOTING 10-59 External Fault Configuration This is a detailed explanation for setting the Fault Class of the configurable external fault/warnings. There are 16 configurable external fault/warnings. The first eight external fault inputs 1 to 8 are hard wired into the digital I/O circuit boards. Inputs 1 to 3 are located on digital I/O board #1, and inputs 4 to 8 are located on the optional digital I/O board #2.
10-60 TROUBLESHOOTING The factory default for the variable “External Fault Class 1” is 0000 hex and the default value for “External Fault Class 2” is FFFF hex, therefore, the default class for all the config. fault / warning input is class 2 “ramp down trip”. If both, External Fault Class 1 and 2 parameters were set to 0000 hex all of the 16 config. faults / warnings would be class 3 “warnings”.
TROUBLESHOOTING 10-61 Example: Consider an application, which utilizes only the config. fault inputs 1, 2, 3 ,5, and 6. The requirements are: Inputs 1, 3 and 6 are to be ramp down trips “class 2”. Input 5 is desired to be an immediate trip “class 1”. Input 2 is to be only a warning “class 3”. 1. Enable or disable the utilized config. fault / warnings by going into “Setup” then into “FAULTS” and setting the appropriate inputs to either “on” or “off”. 2.
