1.2.3.4. Brake testing
When to test
During operation the holding brake of each axis motor wear normally. A test may 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 checked as detailed below:
1. Run each manipulator axis to a position where the combined weight of the manipulator
arm and any load is maximized (max. static load).
2. Switch the motor to the MOTORS OFF position with the Operating mode selector on the
controller.
3. Check that the axis maintains its position.
If the manipulator does not change position as the motors are switched off, then the brake
function is adequate.
