The holding brake in the motor has the task of holding the motor position when the power stage is disabled. The holding brake is not a safety function and not a service brake.

|
UNINTENDED EQUIPMENT OPERATION |
|
oVerify that movements without braking effect cannot cause injuries or equipment damage. oVerify the function of the holding brake at regular intervals. oDo not use the holding brake as a service brake. oDo not use the holding brake for safety-related purposes. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
Releasing the holding brake can cause an unintended movement, for example, lowering of the load in the case of vertical axes.
|
|
|
UNINTENDED MOVEMENT |
|
oTake appropriate measures to avoid damage caused by falling or lowering loads or other unintended movements. oVerify that there are no persons or obstacles in the zone of operation when performing a test of the holding brake. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
Applying the holding brake while the motor is running causes excessive wear and loss of the braking force.
|
|
|
LOSS OF BRAKING FORCE DUE TO WEAR OR HIGH TEMPERATURE |
|
oDo not use the holding brake as a service brake. oDo not exceed the maximum number of brake applications and the kinetic energy during braking of moving loads. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
The times mentioned in the following apply when switching in the direct current circuit, when the motor is warm, and at the rated voltage. The disconnection time is the period from switching on the current to the dying out of the torque to 10% of the rated torque of the brake. The coupling time counts as the period from when the current is switched off to the attainment of the rated torque.
