Does the motor spin at correct rpm when run without the VFD?
Sounds like your motor is 4 pole rather than 2pole like the nameplate suggests.

ACS355 max. speed?

11.04 and 11.05 set the max/min for Ref1 when it is configured as MOP or Floating Point in 11.03, as well as the analog inputs if they are selected.
In the less likely case that MOP is being used as Speed Reference 2, then the max/min is selected by 11.07 and 11.08 which also deals with the analog inputs when they are selected in 11.06

I'm sorry about the delay,
The motor work well but still have to set Parameters 1105 & 2008 to 120 Hz to get a high speed.
See my PDF files with all parameters.

The motor is mislabeled if 120hz gives you 3600rpm shaft speed. It is a four pole 1500/1800rpm motor

Thanks for your help.
I'm not a guru with high voltage motor.
But this simple motor is a 220V or 400V.
In my case, I use the 400v mode. See picture.
I tried to set the parameter 9908 to 3600, but no speed change!
I have to setup the 1105 and 2008 to about 120Hz to get the max. speed! I modified 3 machines with the same result.

The motors are mislabeled. They are four pole 1500/1800rpm.
I believe I already said that.
