1.6.3 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.

The function of the holding brake of each axis motor may be verified as described

1 Run each axis to a position where the combined weight of the manipulator

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 manipulator does not change position as the motors are switched off,

then the brake function is adequate.
