Advanced Ride 4.12. Advanced Ride 4.12.1. Inertia Learn For optimum control of the elevator, it is recommended to learn the system inertia and activate the feed forward torque controller (FFTC). FFTC reduces the dependence on the speed feedback from the motor by predicting what the system will do and providing the required torque command based on that prediction.
Advanced Ride 4.12.2. Internal Internal pre-torque is a feature of the drive which can be used to minimize, if Pretorque not totally eliminate, the rollback which may occur at brake pick, without the need for external load weighing devices. Pretorque is available when the LC01 Control Mode is set for Closed Loop FOC or Closed Loop Synthetic Pretorque.
Advanced Ride 4.12.5. Closed Loop Setting the Control Mode LC01 = 3, Closed Loop Analog Pretorque allows the Analog Pretorque drive to use an external pretorque input signal via AN2+ and AN2- on terminal strip X2A for use with an analog load weighing device. The first step is to ensure the load-weigher is calibrated according to the manufacturer’s instructions.
Advanced Ride 4.12.7. Closed Loop By setting the Control Mode LC01 = 4, Closed Loop Digital Pretorque, a Digital Pretorque fixed digital pretorque value (% of the motor rated torque) is set with LC34 Digital Pretorque. This applies to US04 Control Types Digital (0), Binary (1), Absolute Analog (2), Bi-Polar Analog (3) and Serial Binary Speed DIN66019 Service 50 (6).

Additional Information Direction Selection Failure The Direction Selection Failure will occur if both direction inputs are signaled when the Drive Enable is initially signaled at the beginning of a run. Drive Enable Dropped Whenever the drive enable is dropped, output current will instantly be shut off. If the drive enable is dropped any time during the course of a normal run a Drive Enable Dropped event is logged.

Additional Information Unintended Movement The Unintended Movement event occurs when the difference between the motor position during idle after a normal run, changes by more than the value set in parameter LX25 Unintended Motion Distance. The event is logged and requires a forced reset. A normal run is considered any run profile that is not inspection.
Operation Problems 5.3. Operation Problems Troubleshooting Operation Problems and potential solutions. Refer to Section 5.4 for additional Diagnos- tics Solutions. Additional troubleshooting of learn procedures are listed as well at the end of this section. Problem Cause/Solution/Troubleshoot Check the Motor Current. Refer to Motor Draws High Current for Motor Does Not Move additional troubleshooting.

Operation Problems Problem Cause/Solution/Troubleshoot Motor Draws High Current Verify correct motor data. For PM motors, verify the correct relationship between the Motor Rated Speed, Motor Rated Frequency and the number of motor poles (Diagnostic Screen #12). Refer to the text for further description. Perform a Motor Learn if this has not already been completed.

Operation Problems Problem Cause/Solution/Troubleshoot Encoder slippage/mounting The position of the rotor must be known for synchronous (PM) motors (PM motors) for the drive to properly commutate the stator magnetic field and gener- ate torque. Performing a encoder/rotor position learn (LL05 SPI or LL06 Encoder Pole Position Learn) determines a corresponding encoder po- sition offset value for a given rotor position.

Learn Procedure Troubleshooting 5.5. Learn Procedure Troubleshooting Problem: Troubleshoot: Unable to start learn procedure. Check input signals: The Motor Tune, SPI, and the Encoder Pole Position Learn only require the Drive Enable (I7) to begin (for serial speed control modes, this includes the enable of the Control Word). The Encoder Synchronization and Inertia Learn require a run command (Drive Enable, Direction, and speed command).

Learn Procedure Troubleshooting Problem: Troubleshoot: Unable to complete SPI proce- Ensure correct motor data and that a Motor Tune has been com- dure successfully pleted. During the procedure, if a ‘Values are not consistent’ is displayed, then a learned value falls out of range of the average of previous values and the process will not complete successfully, but can be done again as necessary.

Learn Procedure Troubleshooting Problem: Troubleshoot: Unable to complete Encoder Pole Ensure brake picks and the sheave is free to move relatively easily; Position Learn successfully should be able to rotate by hand. If the displayed position does not appear to change and the sheave does not move back and forth by a few inches, then the sheave is unable to move freely and the procedure cannot be complete.
Transistor Tests 5.7. Transistor Tests The input and output circuits of the inverter can be checked externally with the inverter power off and the motor leads disconnected by use of a multi-meter set to diode check. Note: Different drive housings will have different readings. Measured values per housing are given in tables below.
