Check if the emergency stop switch on the control panel is
pressed. Reset the switch by turning it 45°.
Check if the power connection is correct. Check that there
is full voltage on the motor's phase/phases. If the phase/
phases do not have full voltage, the converter is faulty:
- Reset the electronics by turning the Grinding
knob to "Reset". If this does not help, carry
out a reset procedure as follows Resetting the
frequency converter on page 27.
- Check the error code in the converter, see the
error code table in chapter Electronic error
codes on page 25.
Check the fuses and contactors in the control cabinet.
Recondition the grinding holder by changing the sleeve
(112332 on page 37).
Check that the chassis is straight.
Check that there is movement between the chassis and
grinding head. If necessary, loosen one of the two pins
(310374 on page 29) in order to increase the movement
between the chassis and grinding head.
Recondition the grinding holder, see under The machine
vibrates or wears the tool unevenly on page 23 above.
Check that the chassis is straight.
