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 lifting applications unintentional lowering of the load is prevented by suitable preventive 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.

For this purpose, do the following: 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 drive must be in FCB 01 Output stage inhibit to set the bit.

The following control variables and status variables are available:
