Testing and bedding in the brakes

If a brake does not perform any work by friction over a prolonged period, its friction factor
can change due to rust deposition or vapors created by high motor temperatures. In the
same way, it is possible that slight material deformation becomes noticeable due to high
temperature fluctuations.
In order to ensure the unrestricted functional safety of the brakes, including in the case of
gravity-loaded vertical axes, the brakes must be subjected to regular brake tests.

Testing the brakes

Load the brake with 1.3x the load torque. When energizing the motor, ensure that the sus-
pended load of a vertical axis exerts a torque on the motor even at a standstill.

Brake re-bedding

If the tested brake torque deviates from the required value, a brake can be bedded again.
To perform this action, drive the motor at a maximum of 20 rpm.
Release and close the brake once per second so that the motor has to act against the
closed brake for approximately 0.7 seconds. Repeat these steps in the other direction of ro-
tation after approximately 20 cycles.
If the brake's nominal holding torque is still not correct after this bedding process, perform
the entire process again.
If the brake torque still has not been set after performing the bedding process four times,
check for additional factors that could cause the deviating nominal holding torque, such as
reaching the wear limit.
Depending on the specific servo inverter, the bed-in routine can also be automated. Refer
to the associated documentation on this topic.
