You can select whether or not to activate the under-voltage trip
in case the main power is shut-off.
See "Timing chart for the mains and control power shut off" in
Appendix.
You can set-up the conditions for decelerating the motor after
the over-travel limit input (CCWL: CNI/ F Pin 9 or CWL: CN I/F Pin
8) is made active.
You can set-up the conditions of the following operations after
main power off.
① Decelerating and halting the motor
② Clearing the position error counter

Details of Parameters
Under-voltage protective function
If the main power is lost during Servo-ON, Servo-OFF get active (the motor
does not trip). After this, when the main power is on, Servo-ON will be made
active again.
If the main power is lost during Servo-ON, the under-voltage protective func-
tion (Err-13) is activated, and the motor trips.
