VFD Parameters (Huanyang model)

[gmack (Gerald Mackelburg)]

@Julien

I have pretty much given up on getting a correct readout of the current at the VFD level, I re-read the manual three times front to back, and cannot see any other parameter that would explain why it always reads~1.5A no matter what the spindle is doing. Power-meter it is until further notice.

No luck with the VFD’s analog output voltage (or serial digital?) either? Those might be more useful anyway for real time monitoring and control.. Cutting force is proportional to cutting power.

Note that your power meter’s accuracy will increase as spindle power increases (because the power factor increases).

2019-10-069 Update: @Julien the manual says that setting PD054 to 1 should make the voltage between VO and ACM = 1VDC with a 2 Amp VFD output current with PD055 = 100. Does that seem to work?
