Stop!
The digital outputs are not suitable for the "direct" control of a holding brake!
• Connect the digital output connected to the trigger signal bBrkReleaseOut with a relay
or power contactor which switches the brake supply.
• When a power contactor is used, the response and release time of the earth contact is
added to the response and release time of the brake. Both times must also be
considered for parameterising the closing and opening time of the holding brake

Danger!
A faultless holding brake control function requires a correct setting of the different
deceleration times in the following parameters!
A wrong setting of the delay times can cause a faulty control of the brake!
