Drive functions
7.2 Basic functions
The start of the closing time for the brake depends on the expiration of the shorter of the two
times p1227 (Pulse suppression, delay time) and p1228 (Zero speed detection monitoring
time)
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.
Commissioning
Simple brake control is activated automatically (p1215 = 1) when the Power 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. This can damage the brake beyond repair.
CAUTION
Brake control monitoring may only be activated for Blocksize power units with Safe Brake
Relay (p1278 = 0).
