Electrical connection
The HF spindle may only be operated with a frequency converter (FC).
Ü
Check whether the current, voltage, and frequency data of the HF spindle
match the raw data for the frequency converter.
Ü
Use a motor supply line that is as short as possible.
Ü
Adjust the speed of the HF spindle using the FC.
Ü
Refer to the frequency converter manual for further information.
The FC detects the following operating states of the HF spindle, depending on
the version:
q
HF spindle rotating.
q
HF spindle too hot.
q
HF spindle at a standstill, etc.
The FC forwards the operating states of the HF spindle to the machine con-
troller.
