Spindle spins only at low speed, over current error

[Desertboy]

Hi,

I tried my spindle with a different VFD which has a pot on it and the spindle starts and spins at a slow setting but when I try to speed it up I get an overcurrent/short circuit error

If it was a short it wouldn't spin at all right?

It's the same speed every time that it cuts out at, F has a maximum of 65 I can set it to 12.something before it cuts out

The CY cable is 2.5mm cross section and 5m's long, brand new

I tested continuity from the aviation plug to all 4 sockets in the vfd GND, U, V and W and they are connected, no sign of a short. Pin 1, 2 & 3 connect to U, V, W and pin 4 to earth. Each soldered pin has insulation tape covering it

This spindle is brand new and wouldn't spin up with a HuanYang VFD

Both VFD's rated 2.2kw and it is a 2.2kw water cooled spindle

This is the VFD. I get error 1
