Note:
The pulse suppression control via P1403 (creep speed pulse suppression) and P1404 (timer
pulse suppression) is ineffective when the motor holding brake is activated.

The setpoint transfer after ”Controller enable” is delayed by this time.
During this time, the speed control is internally already active with n-set = 0, so that the axis
does not move while the brake is opening.
After the time has expired, the closed-loop speed control is active and setpoints can be trans-
ferred.

P0852 and P0853 form the criterion for withdrawing the output signal ”Open holding brake” to
close the motor holding brake.
After ”Controller enable” is withdrawn, the drive brakes with n-set = 0.
With the brake sequence control active, the ”open holding brake” output signal is reset, if:
– |n-act| < n holding brake (P0852)
or
– The brake delay time (P0853) has expired

If the output signal ”Open holding brake” is withdrawn, then the drive is controlled, until the con-
troller inhibit time has expired (P0854) with n-set = 0 active (internal controller enable).
In order that the brake has time to close, the closing time is bypassed to prevent a hanging
axis, for example, from sagging. The pulses are only canceled after this time.
