Commissioning the holding brake
To make sure the holding brake is functioning, it has to be tested during startup.
If the regulating device has a function for integrated testing of the holding torque during
secure limited movement and secure limited speed, then use this function and observe
the instructions from the regulating device's manufacturer.
If no such function is present, we recommend that the user proceed as follows:
Limit the permitted range of movement and the maximum speed using the parameters
in the regulating device so that no danger to persons or property can arise from movement
of the axle.
Calculate the power of the drive system 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 drive system with the holding brake applied, gradually increasing the
current to I
M4
. During this, the drive system must not move. Observe the permitted time
for applying current of I
M
4 to the drive system.
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 system. Contact our Sales department.
Always state the serial number (SN) when doing so.
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,
for example by deactivating the controller.
-
It is recommended that the holding torque M
4
of the brake is checked at least once
a day.
