Debugging of ABB VFD for ACS800 Enhancement

A. Motor Auto-tuning (Quick Debugging Steps)

  1. Power On: Ensure the system is powered on.
  2. Input Initialization:
    • Press PAR to select the language. Set 99.1 to ENGLISH.
    • Choose the application macro. Set 99.2 to CRANE.
    • Determine if parameters should be reset to factory defaults. Set 99.3 to YES or NO.
    • Select the motor control mode in 99.4: DTC (Direct Torque Control) or SCALAR.
    • Enter the rated voltage in 99.5 V.
    • Input the rated current in 99.6 A.
    • Specify the rated frequency in 99.7 HZ.
    • Set the motor’s rated speed in 99.8 RPM.
    • Define the motor’s rated power in 99.9 KW.
  3. Motor Identification Run:
    • Proceed to motor identification by selecting 99.10.
    • Generally, choose ID MAGN (the motor won’t rotate).
    • For STANDARD mode (motor rotates), the motor must be disconnected from the equipment.
    • In REDUCED identification mode (motor rotates), the motor remains connected.
    • After selecting the identification mode, a “WARNING” signal may appear.
    • Press the start button to begin motor identification. This process can be stopped at any time using the stop button.
    • Once the motor identification is complete, press RESET to enter actual signal display mode.
  4. Motor Direction Check: Verify the motor’s rotation direction using the control panel.
  5. Input Speed Limits and Acceleration/Deceleration Times: Enter the necessary parameters.
