Cause : PAR HZRPM comes when the drive has detected an inconsistency or issue with the parameters that define the acceptable speed or frequency range for the motor it's controlling.

The F1000 fault code in your ABB ACS310 drive indicates a problem with the speed or frequency limits. This means the drive has detected that the motor's actual speed or frequency is exceeding the parameters set for safe operation.

Check that following applies:

• 2007 MINIMUM FREQ < 2008 MAXIMUM FREQ
• 2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ and 2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ are within range.
