When starting a movement : 1) Forward command/reverse command
The brake timing is turned on simultaneously when control input signal ([FWD] or [REV]) is on.
After the brake releasing time (system para. 83) has elapsed, a rotation starts assuming that it has been
actually released. If [FWD] or [REV] has been turned off during the brake releasing time, the motor will not start
rotation.
2) Pulse train ratio 1, 2
The brake timing is turned on simultaneously when the control input signal is on.
After the brake releasing time (system para. 83) has elapsed, pulse train input becomes effective assuming
that it has been actually released. If the control input signal has been turned off during the brake releasing time,
the pulse train input is not effective
When terminating the movement : 1) Forward command/reverse command
When [FWD] or [REV] has turned off, the motor starts deceleration. After the speed zero [NZERO] signal
on is confirmed, brake timing turns off, and when brake operation time (system para. 82) has elapsed, the
amplifier turns P-action signal on. (For [FWD] or [REV] off in position control, the deviation zero signal on
is confirmed.) Brake timing does not turn off if a movement starts with [FWD] or [REV] signal turned on
during the brake operation time (set by system para. 82).
2) Pulse train ratio 1, 2
After [FWD] or [REV] signal is off, pulse train input becomes invalid with deviation zero signal on.
After the deviation zero signal on is confirmed, brake timing turns off, and when brake operation time
(system para. 82) has elapsed, the amplifier turns P-action signal on.
Brake timing does not turn off if a movement starts when [FWD] or [REV] signal turned on during brake
operation time (set by system para. 82).
