Inovance drive error code 630 indicates overheat protection due to locked-rotor motor. This means the motor connected to the Inovance drive is experiencing conditions that are preventing it from rotating freely and causing it to overheat.

Here's a breakdown of the error and potential causes:

Error Description:

• Code: 630
• Meaning: Overheat protection due to locked-rotor motor

Possible Causes:

• Mechanical Binding: The motor might be experiencing mechanical binding or friction that's preventing it from turning. This could be due to issues like seized bearings, misaligned couplings, or excessive load on the motor shaft.
• Seized Motor: In rare cases, the motor itself might be seized due to internal mechanical problems.
• Incorrect Drive Settings: If the Inovance drive settings are not properly configured for the motor and application, it could lead to the motor overheating.

Troubleshooting Steps:

1. Check for Mechanical Binding: Manually turn the motor shaft by hand to see if there's any resistance. Look for any mechanical issues in the connected machinery that might be causing binding.
2. Reduce Load: If possible, try reducing the load on the motor to see if it helps it rotate freely.
3. Verify Drive Settings: Consult the Inovance drive manual for your specific model and ensure the settings like current limits and torque control are appropriate for the motor and application.
4. Check for Overheating: Feel the motor housing for any signs of excessive heat. If the motor is too hot to touch, it's best to let it cool down completely before attempting to restart it.
