The start of the closing time for the brake depends on the expiration of the shorter of the two
times p1227 (Pulse cancellation, delay time) and p1228 (Zero speed detection monitoring
time)
WARNING
The holding brake must not be used as a service brake.
When holding brakes are used, the special technological and machine-specific conditions
and standards for ensuring personnel and machine safety must be observed.
The risks involved with vertical axes, for example, must also be taken into account.
6.11.3 Commissioning
Simple brake control will be activated automatically (p1215 = 1) when the Motor Module has
an internal brake control and a connected brake has been found.
If no internal brake control is available, the control can be activated using a parameter
(p1215 = 3).
CAUTION
If p1215 = 0 (no brake available) is set when a brake is present, the drive runs with applied
brake. The can destroy the brake.
CAUTION
Brake control monitoring must only be activated for Booksize power units and Blocksize
power units with Safe Brake Relay (p1278 = 0).
