Output stage detection

What does 90 mean?

This fault indicates an incorrect assignment between the motor and the inverter, or an invalid DIP switch setting. The unit cannot properly detect or configure its output stage, preventing correct motor control.

• Output stage fault detected (e.g., short circuit, open circuit).
• Overcurrent or overvoltage on the output.
• Over-temperature of the output semiconductor device.
• Feedback from output stage indicates abnormal condition.

Click steps to track your progress.

1. 1

   Correct the DIP switch settings on the unit according to the motor/inverter combination.

2. 2

   Reset the fault by switching off the DC 24 V supply voltage.
