Is it an XSY-AT1 invertor?

Try the info I posted in reply #20 here. I created a PDF sheet of the parameters with colour coding to help clarify. They do like to change things from time to time plus it depends on exactly what motor is is connected to:

I googled the motor spec and pasted it here for others to see as well. That's is quite a pricey motor !
$2,660.00
VS 31.09-2 Perske spindle motor, model V 30, type VS 31, rectangular motor, 1.35 hp / 1 kW, 30,000 RPM, 500 Hz, 220 V.


XSY-AT1 invertor parameters suggest a max of 400 Hz:
P00 Maximum voltage 0---220.0/380.0 220/380 V
P01 Reference frequency 0---400.0 50 Hz
P02 Intermediate voltage 0---220.0/380.0 110/190 V
P03 Intermediate
frequency 0---400.0 25 Hz
P04 Minimum voltage 0---220.0/380.0 0 V
P05 Minimum frequency 0---400.0 0 Hz
P06 Maximum operating 0---400.0 65.0 Hz
P07 Minimum operating 0---400.0 0 Hz

Plus the parameters all need to be set to match the motor specs, unless it was shipped configured for you
