please share the schematic
Re: MX4660 Speed Control for 2.2 KW huanyang vfd
The MX4660 schematic is not released, there is a channel to output analog signal to control VFD. Refer to page19 http://www.leadshine.com/UploadFile/...4660d_V1.2.pdf
PIN14 for PWM on DB25, PWM pulse input. Used to get the PWM signal from the controller which will bethen transformed into an analog signal to an external device connected at“0-10V out” pin of the analog output connector (CN8 on Figure 3), such as aVFD for spindle speed control.

Using the MX4660 Controller with a VFD
The 6 outputs of the MX4660 are each an optical isolator in series with a 1,000 ohm resistor and this limits how the outputs can be used. If you want to control a device that uses 12 volts, the 1,000 ohm series resistor limits you to a maximum of 12 ma current, probably not enough to do much more than light up an LED. To use the outputs to control the Forward and Reverse signals of a VFD you will need to add some type of driver device, typically a relay with a driver on the coil side since the 12 ma output is not enough to reliably control even a small relay.
I know this is an old post, but I had found it recently when researching how to wire up my Leadshine MX4660 with the 2.2kW Huanyang VFD. I had jumpered the FOR signal with DCM to get things running. Once I got the spindle up and running I ran the jumper through the current setting on a voltmeter (actually 2 to double check) and both read 2.3 mA. The documentation I have on the MX4660 lists 70 mA for the outputs. So I hooked the FOR and DCM wires directly to the output (Output 6+ and 6-, respectively in my case). This also worked in initial testing.

Yes, any of the outputs should work for the On/Off of the VFD Drive, or if they have a relay board the Rely can be turned On/Off as well, using a Relay can make it a safer system for the operator
