• Timing of Servo ON and brake control signal when the motor is stopped.
The load may move a little due to gravity if the servo is turned on when the motor is
stopped. If then, adjust the delay time from the point when the internal Servo ON signal
is inputted in SEt-76 up to the point when the brake releasing signal is outputted.
Excessive setting of delayed time may cause an error in the operation of the servo drive.

• Reduces shift of the load when the servo status is on.
- In case of vertical load, the load is shifted a little then restore the position when the servo
is on. If that's the case, shift of the load can be reduced by SEt-64, SEt-65.
- It is effective in case of vertical load. Motor may rotate in one direction during the servo
ON if applied in a horizontal load.
- SEt-64 and SEt-65 cannot be set other than "0" at the same time.
- Set as shown on the next page (case1 and case2).
