2. If brake is controlled by drive, the drive will act by the normal operation to finish tuning
after wiring and setting brake control parameters.
3. If brake is controlled by the host controller, it needs to make sure that brake is in release
state before tuning.
NOTE
The rated speed can’t be larger or equal to 120f/p.
Please notice that if the electromagnetic valve and brake is not controlled by the AC
motor drive, please release it by manual.
It is recommended to set Pr.08-00 to 1 (unloaded motor) for the accurate calculation.
If it needs to execute this function with loaded motor, please balance the carriage
before execution.
if it doesn’t allow balancing the carriage in the measured environment, it can set
Pr.08-00=3 for executing this function. It can execute this function with loaded motor
by setting Pr.08-00=3. It will have a difference of 15~30
o
by the different encoder
type.
It will display the warning message “Auto tuning” on the digital keypad during
measuring until the measure is finished. Then, the result will be saved into Pr.08-09.
It will display “Auto Tuning Err” on the keypad when stopping by the fault of the AC
motor drive or human factor to show the failed detection. At this moment, please
check the connections of the wirings of the AC motor drives. If it displays “PG Fbk
Error” on the digital keypad, please change the setting of Pr.10-02 (if it is set to 1,
please change it to 2). If it displays “PG Fbk Loss” on the digital keypad, please
check the feedback of Z-phase pulse.

This value should be set according to the rated frequency of the motor as indicated on the
motor nameplate. The factory setting is 90% X rated current.
Example: if the rated current for 7.5hp (5.5kW) models is 25A and the factory setting is 22.5A.
In this way, the current range will be from 10A (25*40%) to 30A (25*120%).
