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.

6.11.3Commissioning

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).
