Tip!
For direct triggering of a holding brake, the high current output of the 8400 TopLine
controller can be used that can switch max. 2.5 A. For this purpose, connect the
bMBrakeReleaseOut trigger signal to the bOutHC input of the SB LS_DigitalOutput .
From version 15.00.00 , the bOutHC_BrakeApplied status signal of the SB LS_DigitalInput
can be used for a simple monitoring of the switching status of a holding brake connected
to the high current output.  Switching status of the motor holding brake at the high
current output ( 397)
bMBrakeApplied
BOOL
Input for status detection via switching contacts at the brake
• Only effective if bit 5 in C02582 is set to "1".
FALSE Brake is released.
TRUE Brake is applied.

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
