Brake grinding function
The control unit can activate the brake grinding function separately for each of the two brakes. Use action
B301
for brake 1 and
B302
for brake 2. We will now describe action
B301
for brake 1. The description also
applies to brake 2.
During the brake grinding function, the brake is repeatedly applied for approx. 0.7 s and then released for
approx. 0.7 s while the motor is rotating with approx. 20 rpm. This grinds off any deposits from the friction
surface which may affect the halting function. You can parameterize the following settings:
•
How often the brake is applied (
B308
) during rotation.
•
How often the drive is to rotate in each direction (
B309
).
•
Whether one direction of rotation is inhibited (
B306
).
WARNING!
Danger of personal injury or property damage due to defective motor halting brake. Starting the brake
test action releases the motor brakes one after the other. During the encoder test and/or in the case
of a faulty brake, the drive axis may move.
Please take special precautionary measures - above all for gravity-stressed axes.
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.
Information
Please note that the brake grinding function is defined for the STOBER system (gear motor with
brake and, if applicable ServoStop). For example, you cannot use the brake grinding function with
brakes that are attached to the output power of the gear unit. It is essential to clarify the technical
demands on a system from another manufacturer before you use this function.
Information
During the
brake grinding
action, the cycle time is set internally to 32 ms. The change occurs when
the action is activated. After the action is concluded, the previous cycle time is used again.
