You cannot have a true 600 volts at the disco or at the soft start output terminals unless the soft start had ramped to full speed and the motor is running.
I think you are reading millivolts. Are you using a digital true RMS meter?
I bet if you use an analog meter set to the correct voltage range you will read less the 1 volt.
It is theoretically and physically impossible to apply 600 volts to a 600 volt motor and for it not to run. This is definitely a operator error regarding the meter.
To verify, check the current. There will be none.
