Operating mode
For different applications and tasks, different operating modes are available under
. 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
) 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 brake activation and elapse of the brake application time, the controller is
inhibited automatically by the basic function "holding brake control".
Tip!
You can use mode 11 to easily check if the brake switches correctly.
Mode 12: Automatic control
In this mode, the brake is controlled automatically.
If the requested speed setpoint reaches a parameterisable upper speed threshold that
allows traversing of the drive, the brake will be released and operation enabled.
On the other hand, if speed setpoint and actual speed fall below a parameterisable
lower speed threshold, the brake will be applied under consideration of different time
parameters.
The brake will also be activated automatically if quick stop is activated in the drive, e.g.
by a device command or as response to an error, and in the event of controller inhibit
or pulse inhibit.
After automatic brake activation and elapse of the brake application time, the
controller is inhibited automatically by the basic function "holding brake control".
