  • Page 21: Encoder Errors

    Chapter 2 – Explanation of Functions Encoder Errors If the signal from encoder doesn’t correspond to the inverter output for any reason, then the inverter displays a trip event. 1. Speed deviation error Inverter enters the trip state when a speed deviation is detected due to abnormal signal from encoder or abnormal shaft speed caused by the load.

  • Page 22: Frequency Conversion Function

    Chapter 2 – Explanation of Functions Note: If before the encoder error, another error (e.g. over current) is detected, then the prior error causes the trip event. Therefore the encoder error display may not be shown even if there is an encoder error.

    – Chapter 4 Adjustment Setting and Adjustment of Motor Constants When using vector control, the motor parameters shown below must be entered into the inverter to obtain optimal performance. This is normally done via the auto-tuning procedure described in Appendix A, whereby the key parameters are measured automatically. This procedure must be performed before initial operation of the elevator.

  • Page 36: Adjustment Of Speed Response

    – Chapter 4 Adjustment 4.3 Adjustment of Speed Response Optimization of speed response is achieved by adjusting the response to the torque change when the brake is released. For a typical elevator application, the Motor Speed Proportional Gain Constant (H005) setting should be in the range of 2.0 to 10.0.

  • Page 37: Adjustment Of Inertia

    – Chapter 4 Adjustment 4.4 Adjustment of Inertia Inertia J (H024 and H034) should be adjusted to avoid overshoots or undershoots as shown in Figure 2.1. These undershoots or overshoots decrease with an increased value of inertia J. Increase the value of inertia J gradually to eliminate overshoot and undershoot.

  • Page 43 Appendix A - Auto-tuning Procedure Auto-tuning of Motor Constants The SJ300 inverter features auto-tuning, which detects and records the motor characteristic parameters to use in all vector control modes. Auto-tuning determines the resistance and inductance of motor windings. Therefore, the motor must be connected to the inverter for this procedure.
  • Page 44 Appendix A - Auto-tuning Procedure WARNING: You may need to disconnect the load from the motor before performing the DYNAMIC autotuning procedure. The inverter runs the motor forward and backward for several seconds without regard to load movement limits. Preparation for the Auto-tuning Procedure e sure to check the following items and verify the related inverter configuration before going further in this procedure.
  • Page 45 Appendix A - Auto-tuning Procedure Performing the Auto-tuning Procedure fter the preparations above are complete, perform the auto-tuning procedure by following the steps: . Set H001 = 01 (auto-tuning without motor rotation, or STATIC), or H001 = 02 (auto-tuning with motor rotation, or DYNAMIC). urn the RUN command ON.
  • Page 46 Appendix A - Auto-tuning Procedure Possible Problems You May Encounter The following problems may be encountered during the autotuning procedure: • Trip during auto-tuning – A trip event will cause the auto-tuning sequence to quit. The display will show the error code for the trip rather than the abnormal termination indication.
  • Page 47 Appendix A - Auto-tuning Procedure Manual Adjustment of Motor Parameters Should the performance after auto-tuning not be optimal, the various motor parameters may be manually adjusted. The following table shows the symptoms and suggested adjustment for various operating conditions. Observe the system and make the adjustment indicated until acceptable performance is obtained.
