WARNING!
Danger due to movement of the drive. During the action, the motor
rotates at approx. 20 Rpm and with the torque entered in C03 or C05.
Ensure the following.
 Before the function starts, make sure the drive is in a position in which it is
permissible for it to move at this speed and torque.
 Restrict the direction of rotation in B306 if the drive is not permitted to rotate
in a particular direction.
 Check E62 and E66 to see whether other torque limits are also in effect.
11.10.1 Single-axis operation
Preconditions for using the brake grinding function:
• Brake control is parameterized and activated.
• Enter how often the brake should engage while turning in one direction in
B308.
• Enter how often the drive should be ground in each direction in B309.
• Specify whether one direction of rotation is disabled in B306.
• The brake should be ground at its maximum holding torque. Make certain
that the torque limit in the drive controller permits this. To do this check
parameters E65 actual positive T-max and E66 actual negative T-max. Also
note section 13.6 Limit torque, force.
Proceed as follows:
Information
Note that the brake grinding function is defined for a STOBER drive
(geared motor with brake). For example, it is not permitted to use
the brake grinding function for brakes that are attached to the output
drive of the gear. Always make certain the technical requirements
for a third-party system have been clarified before using.
Information
If you would like to perform the action and brake management
considers a brake test mandatory (fault 72), the fault must be
acknowledged before the action starts. Once you have
acknowledge the malfunction, you can continue with the brake
grinding function instruction.
