External fault

What does EPF mean?

This fault is triggered by an external condition or device connected to a logic input configured for external fault detection. This input is typically connected to a safety circuit, thermal switch, or another protective device. If the external fault condition persists, the drive will remain in a fault state, preventing operation until the external issue is cleared, ensuring machine and personnel safety.

1. 1

   Identify the specific external device or condition connected to the drive's logic input that is configured to trigger this fault.

2. 2

   Inspect the wiring and operation of the external fault input circuit, ensuring the external device is functioning correctly.

3. 3

   Clear the external fault condition as per the external device's documentation or manual.
