Set Pr.08-00 to 1 (unloaded motor) for accurate calculation. If you need to execute this function with a
loaded motor, balance the carriage before execution.
If you do not balance the carriage in a measured environment, you can execute this function with a
loaded motor by setting Pr.08-00 = 3. It will have a difference of 15–30
o
for different encoder types.
“Auto Tuning Err” displays on the digital keypad when stopping due to an AC motor drive fault or human
error, which means the detection fails. Check the wiring connections of the AC motor drive If “PG Fbk
Error” displays on the digital keypad, change the setting of Pr.10-02 (if set to 1, change it to 2). If “PG
Fbk Loss” displays on the digital keypad, check the feedback of Z-phase pulse.
