Simple Brake Control - Siemens SINAMICS G150 Operating Instructions Manual

Simple brake control

Description
The "Simple brake control" is used exclusively for the control of holding brakes. The holding
brake is used to secure drives against unwanted motion when deactivated.
The control command for releasing and applying the holding brake is transmitted directly to
the converter via DRIVE-CLiQ from the control unit, which logically combines the signals with
the system-internal processes and monitors these signals.
The converter then performs the action and controls the output for the holding brake
appropriately.
The operating principle of the holding brake can be configured using parameter p1215.
Figure 9-8
The start of the closing time for the brake depends on the expiration of the shorter of the two
times p1227 (standstill detection monitoring time) and p1228 (pulse cancellation delay 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 must also be evaluated, such as risks associated with suspended axes.
