Malfunctions

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

HF spindle not rotating

Cause

Troubleshooting

No 
power supply

q

Check the frequency converter.

q

Check the machine.

q

Check all electrical connections.

q

Check all wires in the motor cable.

q

Activate the Start/Reset button.

Thermal protection has
been activated

q

Wait until the HF spindle has cooled down.

q

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

q

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

Tool change 
initiated

q

Turn off the pneumatic system for the tool change.

HF spindle becomes hot

Cause

Troubleshooting

Insufficient cooling

q

Check the power of the chiller.

q

Check the water level of the chiller.

q

Check the connections and the cooling hoses.

q

Check the cooling circuit.

q

Check the chiller for error messages.

Phase missing

q

Check all wires in the motor cable for cable breaks.

Machining too heavy

q

Check the rotational direction of the HF spindle.

q

Check the rotational direction of the tool.

q

Check the tool for damage.

q

Reduce the machining load intensity.

Frequency converter
incorrectly set

q

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