Brake control (Brake)

WARNING

Uncontrolled system behavior when the brake is released.

Severe or fatal injuries, e.g. due to falling hoist.

• Make sure that the system does not automatically start moving when the brake is released.
• Make sure that in hoist applications unintentional lowering of the load is prevented by suitable protective measures.

The Brake structure contains control variables and status variables for controlling the brake in special cases, e.g. if a drive is not supplied with current (is in controller inhibit) and is to be moved manually.

In the configuration of the axis in MOVISUITE^®, first set the parameter "Release brake with inhibited output stage – enable?" under "Drive functions" > "FCB 01 Output stage inhibit. (FCB 01 Output stage inhibit)" to Yes. The brake can then be released by setting xBrakeOpen to the value "TRUE".

The following control and status variables are available:
