6.2.2 Warning end lock angle (lock angle reserve)
The brake pads wear out in the course of operation. The turntable
controller compensates for this by offsetting the switch-off angle.
If the end of the lock movement is reached then the warning "
End
lock angle"
is output to the PLC.
The turntable can still be operated. However we recommend that
you check the brake at the next possibility and replace it if
necessary.
If the brake is not checked, over time this fault results in a system
fault
"End lock angle"
and further operation is disabled.
Possible causes
Measures
Brake pads are worn or the brake is defective
Check the air gap of the brake and adjust
Replace the brake if necessary
Turntable overloaded
Reduce the load to the calculated value
Turntable cycle time too short
Reduce the motor speed so that the turntable cycle
time is not underranged
Reset fault
NOTE!
Eliminate cause.
Unscrew the cover on the turntable control unit.
Press the reset button for at least 3 s.
System fault LED goes out.
Turn the turntable several times at operating speed.
Press the reset button and the default values will be used for
