The output from the software WinPCNC PWM signal for the spindle speed is converted by the
zero-3 into an analogue control signal and outputted to the 0-10Volt LPT2 output.
Thus you can connect an inverter to operate a HF spindle directly to the Zero-3 controller.
-
Make sure that the control is turned off.
-
Connect the power cable of the inverter to the power outlet 1 (Rel.1) Zero-3 controller.
-
Connect the "control cable" of the inverter with the LPT2 output of the controller.
-
Make sure that you back up all connections with the knurled screws from loosening.
-
Observe the notes from page 6 for max. Power consumption.
Caution:
Inverter and HF spindles that have higher performance, can also be used, but require an external
power supply!
