Motor or VFD will not start: information for troubleshooting

If the motor or VFD is not starting normally, stop using it and collect the details below so we can identify the correct troubleshooting path.

What to send support

• Your order number and photos of the motor and VFD model/rating labels.
• The voltage option ordered and any changes made since delivery.
• What happens when you use the normal external controls: no response, an indicator/error, humming, stopping under load or a breaker trip.
• A clear photo of the indicator/error display. If safe to do so without recreating a fault, a short video can help.
• Whether the package worked previously and when the symptom began.

Before further operation

Use the instructions supplied for your exact equipment. Do not open the VFD, change internal settings, rewire the motor or repeatedly reset a tripping circuit to continue operation. Have electrical supply and protection questions checked by a qualified electrician. Do not bypass grounding or protective devices.

If there is smoke, a burning smell, damage or unusual heating, disconnect power when safe and do not run the equipment again pending guidance.

Email the details to support@diktatorgrinder.com. See Power Requirements and Current Draw for Diktator Grinder Motors for selecting the correct power information.
