Malfunctions

The list below can be used to quickly investigate and eliminate faults.

HF spindle not rotating

Cause

Troubleshooting

No
power supply

Check the frequency converter.

Check the machine.

Check all electrical connections.

Check all wires in the motor cable.

Activate the Start/Reset button.

Thermal protection has
been activated

Wait until the HF spindle has cooled down.

Check the frequency converter for error messages. If no
messages are illuminated, start the frequency converter.

(See also “Spindle becomes hot

Frequency converter
has
shut down

Check the error messages in the frequency converter man-
ual.

Tool change
initiated

Turn off the pneumatic system for the tool change.

HF spindle becomes hot

Cause

Troubleshooting

Insufficient cooling

Check the power of the chiller.

Check the water level of the chiller.

Check the connections and the cooling hoses.

Check the cooling circuit.

Check the chiller for error messages.

Phase missing

Check all wires in the motor cable for cable breaks.

Machining too heavy

Check the rotational direction of the HF spindle.

Check the rotational direction of the tool.

Check the tool for damage.

Reduce the machining load intensity.

Frequency converter
incorrectly set

Compare the values for the HF spindle with the set values
on the frequency converter.
