4.5.3.1 Description of the Brake Management System
On drives with a motor holding brake, the brake can be operated manually or automati-
cally depending on the state of the drive.
The triggering is effected by means of a selectable digital output. A digital input must be
selected to detect the brake state. The outputs and inputs are located on terminal X2. The
brake state can be monitored. When monitoring is active, an error message is transmitted
in the event of an error (brake could not be enabled/applied).
Adaptation to the differing reaction times of holding brakes is possible by means of con-
figurable response times and delay times.
Manual Brake Triggering
The brake can be applied and enabled independently of the state of the
Bit 0).
Automatic Brake Triggering
In the Automatic mode, the brake is actuated depending on the state of the device con-
troller (see

When the drive is started, power is applied to the motor in state transition 3 4
("Switched On" "Operation Enabled") before the brake is enabled. This prevents a sus-

pended axis from sagging. The requirement for this is at least a speed-controlled operat-
ing mode.
NOTE!
A suspended axis will NOT be prevented from sagging in the following cases:
