Setting up VFD to run without a controller in router table.

[routercnc]

Thanks Lee.

Back to the OP - it was a long time ago but I think I used this VFD on my CNC machine, or something very similar.

So if you know the 2.2 kW motor specs you can set up PD003 - PD008 to match, as shown on page 19.

As you say the manual does state set PD001 = 0 to use the built in control panel for on/off and PD002 for the operating frequency (speed) as PD002 = 0 and that should allow you to control the motor using the built in control panel. That is a good place to start to make sure the motor is running OK. You mention not hearing a relay click - here is no relay for the main motor control, it is all done with power electronics so there is no sound (from the VFD) when it starts and stops. There is often a relay inside the unit but this is for auxiliary control.

Once it is running OK you can set PD001 = 1 and PD002 = 1 for external/terminal control, but note on page 10 you also need to move the jumper to connect pins 1 & 2 to allow the external potentiometer in the terminals to work.

To get external control working you then just need to make a simple connection between FOR and COM for forwards, and REV and COM for backwards. This is shown on the diagram on page 12; in their example they have used a push button switch between the terminals FOR and COM. The dotted ellipse is a shield meaning shielded cable but for bench testing you can just use a piece of wire between the terminals. Note the motor will only run when FOR and COM are connected, and stop when they are released. I think I used a latching relay to hold the run until I pressed stop.

For the potentiometer connect as shown on page 12. Connect one side of the pot to VR+10V/5V, one side to ACM (GND) and the middle wiper terminal to VI. Ignore AI. Essentially you are just putting 10V across the potentiometer and the wiper arm is reading off a value between 10V and 0V for the user speed.

Reserved usually just means not used on this model or reserved for future use.

For gentle acceleration try setting PD014 to whatever ramp up time you want in seconds. I'm not sure if you need to tell it to use PD014 (accel time 1) or that is a default.
