Possible Causes
Failed start circuit in drive, Seized motor, Incorrect programming (speed set to 0), Internal relay failure
How to Fix / Troubleshooting
Safety first: Turn off power before mechanical inspection.
- Step 1 – Verify speed setting: Ensure a valid speed is programmed and selected (not 0 RPM).
- Step 2 – Check shaft rotation: With power OFF, attempt to rotate the motor shaft by hand. If seized, the motor has failed.
- Step 3 – Listen for drive activity: When starting, listen for any click or hum. Total silence with a live display often indicates a failed drive output.
- Step 4 – Replace motor/drive: SuperFlo VS uses an integrated drive; if it will not start with correct programming and free shaft, replace the motor/drive assembly.
