The F1000 alarm code on your ABB ACS355 drive indicates a parameter inconsistency. This means the drive has detected a conflict within its programmed settings.

1. There are several parameters within the drive that define its operation, such as motor speed limits, acceleration/deceleration rates, and control logic.
2. The F1000 alarm signifies that some of these parameters might be incompatible with each other or outside of acceptable ranges.
3. Check parameter settings. Check that following applies:
   • 2001 MINIMUM SPEED < 2002 MAXIMUM SPEED
   • 2007 MINIMUM FREQ < 2008 MAXIMUM FREQ
   • 2001 MINIMUM SPEED / 9908 MOTOR NOM SPEED, 2002 MAXIMUM SPEED / 9908 MOTOR NOM SPEED, 2007 MINIMUM FREQ / 9907 MOTOR NOM FREQ and 2008 MAXIMUM FREQ / 9907 MOTOR NOM FREQ are within range.
