Error of output stage interlock

Hva betyr F7043 ?

This safety fault indicates a problem with the interlock circuit that controls the output stage (power section) of the drive. The interlock is a critical safety mechanism that prevents the drive from applying power to the motor unless all safety conditions are met, and an error means it's not functioning correctly.

• Faulty internal hardware (e.g., relays, contactors) of the output stage interlock.
• Short circuit or open circuit in the interlock control path.
• Incorrect external wiring to safety inputs, preventing the interlock from being correctly released.
• Internal diagnostic failure of the safety module monitoring the interlock.

1. 1

   Cycle power to the IndraDrive.

2. 2

   Verify all external safety input signals (e.g., STO, enable) are present and correctly wired, ensuring they are not preventing the interlock from clearing.

3. 3

   Review relevant safety parameters in the IndraDrive that control the output stage interlock.

4. 4

   Check the drive's internal diagnostics (if available) for specific error codes related to the output stage or safety relays.

5. 5

   If the fault persists after external checks, the drive's safety module or power section hardware likely requires service or replacement.
