Value/meaning

bMBrakeReleaseOut

BOOL

Trigger signal for switching element holding brake control via a digital output

• Use bit 0 under

C02582

to activate inverted switching element triggering.

Functional settings

FALSE Apply brake.

TRUE Release brake.

bMBrakeReleased

BOOL

"Brake released" status signal considering the brake release time

• When the holding brake is triggered to close, bMBrakeReleased is immediately set

to FALSE even if the brake closing time has not yet elapsed!

TRUE Brake released (after the brake release time has expired).

Stop!

The digital outputs are not suitable for the "direct" control of a holding brake!

• Connect the digital output connected to the trigger signal bMBrakeReleaseOut 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
