• 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

• 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).
