• You must input data from the motor nameplate or motor test report to do Auto-Tuning. Make sure that this data is available before you do Auto-Tuning.

  • For best performance, make sure that the drive input supply voltage is equal to or more than the motor rated voltage.

    Note:

    Better performance is possible when you use a motor with a rated voltage that is less than the input supply voltage (by 20 V for 200 V class models or by 40 V for 400 V class models). This is very important when you operate the motor at more than 90% of base speed, where high torque precision is necessary. If the input power supply is equal to the motor rated voltage, the drive output voltage will not be sufficient and performance will decrease.

  • Push [STOP key] on the keypad to cancel Auto-Tuning.

  • If a Safe Disable input signal is input to the drive during Auto-Tuning, Auto-Tuning measurements will not complete successfully. If this occurs, cancel the Auto-Tuning, then do it again.

  • Table 1 shows the status of multi-function input/output terminals during Auto-Tuning.
