ATN1 MAX SPEED LOW fault in Parker AC890 drive - During Autotune the motor is required to run at the nameplate speed of the motor. If MAX SPEED RPM limits the speed to less than this value, an error will be reported.
- Increase the value of MAX SPEED RPM up to the nameplate rpm of the motor (as a minimum).
- It may be reduced, if required, after the Autotune is complete.
