Power Unit

What does F070 mean?

A critical failure has been detected within the drive's power section (e.g., rectifier, DC bus, inverter IGBTs). This indicates a significant internal hardware component failure that severely impacts the drive's ability to convert and deliver power to the motor. This usually requires component replacement or drive replacement.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Inspect for any visual signs of damage within the drive's power section, such as burnt components or bulging capacitors (requires qualified personnel and power off).

2. 4

   If the fault cannot be cleared after basic troubleshooting, replace the drive as power unit failures are typically not field-repairable.
