9.11.6 Carry out brake test
This function can be used to check the holding torque of the brake.
O
Tip!
You can carry out this test regularly to early detect defects or wear of the brake in
good time.
Requirements
To activate the brake test, the following conditions must be fulfilled:
r The test torque in C02594 is set higher than 0 Nm.
r The permissible angle of rotation in C02595 is set higher than 0° and thus standstill
monitoring is active. Standstill monitoring
(C 214)
r The brake is activated, i.e. the "brake closing time" ( C02589 ) and the "waiting time for
status monitoring" ( C02591 ) are elapsed.
r No other source for controller inhibit is active so that the controller inhibit can be
deactivated by the brake control.
Function only implemented from bundle 1.1!
Note!
Due to possible deviations in the torque generation, the test of the holding
torque cannot determine the holding torque exactly!
• The generated motor torque can deviate up to ±15 % from the default value
depending on temperature.
