
Calculate the power of the motor I
M4
required to achieve the holding torque M
4
with the torque
constant, and limit the maximum current of the regulating device to this value.

Apply current to the motor with the holding brake applied, gradually increasing the current to
I
M4
. During this, the motor must not move. Observe the permitted time for applying current of
I
M
4 to the motor.

If movement does occur, the user should ideally switch off the current supply automatically to
avoid uncontrolled movement of the axle.

If the holding torque M
4
is not reached, perform the grinding-in process described by the
brake manufacturer.

After the grinding-in process check again the holding torque M
4
.
If the holding torque M
4
specified in the brake's technical data is reached, then the holding brake is
ready for operation.
If the holding torque M
4
specified in the brake's technical data is not reached then:

Repeat the grinding-in procedure.

The grinding-in process may only be repeated twice during a testing procedure for the
holding torque M
4
.
If the holding torque M
4
is not reached after the third grinding-in process then the holding brake is
not functioning properly :

Do not start up the drive. Contact our sales department.

Always state the serial number (SN) when doing so.
6.2.4 Testing the holding brake regularly
To ensure the permanent functioning of the holding brake, it has to be regularly applied and
checked.
- It is recommended that the holding brake is released and applied at least twice daily by
deactivating the controller.
- It is recommended that the holding torque M
4
of the brake is checked at least once a day.
6.3 Data for the electrical startup

In some servo controllers, there are dependencies between individual parameters. We would
be glad to assist you in finding the correct entries.
The servo controllers of the different manufacturers generally use an
individual annotation of the data.
If the data is disregarded, the motor and/or the servo controller may be
damaged.

Observe the listed units precisely and check their conformance with the
units of the servo controller.

If the units differ, make the necessary adjustment accordingly.
