8.2.1.1 Functional changes from firmware version 05.00.00
8.2.1.2 Operating mode
For different applications and tasks, different operating modes are available in C02580 . The
selected operating mode determines whether the holding brake control is used and how the
holding brake will be switched.
Mode 0: Brake control off
In this mode, brake control is switched off (not active).
• The trigger signal bBrkReleaseOut for the holding brake control switching element is set to
FALSE.
• The status signal bBrkReleased is set to FALSE.
Mode 11: Manual control
In this mode, brake release and brake application can be directly controlled via the input bBrkRelease
(Configuration: C00701/19 ) without special logic or automatic.
• Setting pulse inhibit or controller inhibit has no influence on the trigger signal bBrkReleaseOut
for triggering the power output (terminals BR1 and BR2).
• After the brake has been activated and the brake application time has expired, the controller is
inhibited automatically by the basic "Holding brake control" function.

Tip!
You can use mode 11 to easily check if the brake switches correctly.

Note!
From version 05.00.00 onwards , the holding brake control changes as follows:
• There is no synchronisation ramp anymore. C02610/1 has no function.
• If the switching threshold ( C02581/1 ) is set to "0", the resulting switching thresholds
for opening and closing the holding brake are "0" as well.
• If the axis moves horizontally ( C02582 , bit 3 = "1"), the speed setpoint does not freeze
while the holding brake is closed.
