Fuji Electric Faldic-a RYS-R Series - Brake Release Time; Brake Operation Time

5-38
MHT260a (Engl.)
2) Pulse train ratio 1 / Pulse train ratio 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.
The same procedure as when starting a movement above, is performed if a rotational command is turned on
during brake operation time.
System parameter 81 to 83
Para. Name Setting range Initial value Change
81 Operation at stoppage 1: Servo lock, 2: Brake (P-action),
3: Brake (free-run)
1 Power
82 Brake operation time 0.01 to 9.99 [s] (in 0.01 step) 0.50 Always
83 Brake release time 0.01 to 9.99 [s] (in 0.01 step) 0.20 Always
Brake timing : Validated signal at ON level
・Brake release time
Time period from when the amplifier output is on, until when the external brake release is ended. Just after the brake release time, the brake
is operating and the motor is in servo lock status.
The ON level of the rotational command makes the P-action signal off. The P-action signal is on inside the amplifier.
・Brake operation time
Time period from the amplifier output is off, to starts the braking operation.
After positioning is ended, brake timing output is turned off. Just after the brake operation time, the motor is stopping by servo lock only.
During brake operation time, the servo lock and the brake is in operation. After the brake operation time has elapsed, P-action is on and the
motor stops with brake.
