ABB IRB 120 User Manual

1.2.5.4 Brake testing
When to test
During operation, the holding brake of each axis normally wears down. A test can
be performed to determine whether the brake can still perform its function.
How to test
The function of the holding brake of each axis motor may be verified as described
below:
1 Run each robot axis to a position where the combined weight of the robot
arm and any load is maximized (maximum static load).
2 Switch the motor to the MOTORS OFF.
3 Inspect and verify that the axis maintains its position.
If the robot does not change position as the motors are switched off, then
the brake function is adequate.
