10.10.1 Device parameters
Brake release delay on starting
Caution
Only effective with simultaneous SWITCH-ON command for brake and motor.
Caution:
• Positive times: Delayed switch-on of the brake output with respect to the
motor.
• Negative times: Delayed switch-on of the motor with respect to the brake
output.
In reverse operation, the release delay only starts when the lock-out time
has elapsed.
Setting range: –2.5 seconds to +2.5 seconds.
Brake hold time on stopping
Caution
Only effective with simultaneous SWITCH-OFF command for brake and motor.
This device parameter causes a delayed switch-off of the brake output with
respect to the motor. It is also active when the PLC fails.
In reverse operation, the hold time and lock-out time run simultaneously.
The motor cannot be switched on in the opposite direction until the lock-out
time has elapsed. The motor can be switched on in the same direction immedi-
ately, since the lock-out time is interrupted.
Setting range: 0 to 25 seconds
Priority control
'Brake release delay on starting' has priority over 'Brake hold time on stopping'.
An elapsing hold time is terminated when the release delay is restarted (via a
SWITCH-ON command for the brake and motor).
