External Fault (Terminal S6)

MFDI terminal S6 caused an external fault through an external device.

  1. Find the device that caused the external fault and remove the cause.

  2. Clear the external fault input in the MFDI.

The wiring is incorrect.

Correctly connect the signal line to MFDI terminal S6.

External Fault [H1-06 = 2C to 2F] is set to MFDI terminal S6, but the terminal is not in use.

Correctly set the MFDI.
Note:

If the drive detects this error, the terminal assigned to H2-01 to H2-04 = 10 [MFDO Function Select = Alarm] will be ON.
