Most VFD's need a parameter setting to enable external control as they default to the pot and keys on the front.

Then you need to set the input parameter for control to PVM or 0-10V or what ever your system outputs then all you should need is to connect the run/fwd switch to your relay and configure spindle output in ports and pins.

Some pictures of the VFD will help us to give you better info.

Remove Mach3 from your computer, download a genuine copy from the newfangled website, reinstall and try again in demo mode.

Do NOT use a licence file from a disk/download that came with a breakout board.

CS-Lab / Re: shifts / offsets after some machining time with CSMIO IP-M

Your steps/mm are a fixed number and once set should never need changing.  A simple calculation gets you the correct figure based on number of pulses for one rotation of the leadscrew divided by pitch.

In most cases upping the acceleration time and/or reducing velocity is the fix.  Try doubling the accel time by reducing the value by half.  If you set it very low e.g. 25 you will see and hear it ramp up and down.

The other thing to watch is we can have too many microsteps, depending on the resolution you need and the pitch of the screw its not necessary to have more than 400 as this with 5mm pitch screws will give 0.0125mm resolution as an example, the benefit is the torque of the motor it much higher and lost steps are less likely.

The other problem can be the drivers getting hot and breaking down, do you have a good fan blowing over the drive fins?

We need more details to give an answer:-

Machine type, lathe, mill etc.

Are you swapping tools in a single holder or swapping holders with tools.

What is the setup of the machine

Pictures always help.

Pokeys turns on a relay that turns on the machine main power pokeys can be powered by a small psu of its own.
