External Fault

Was bedeutet EF3 ?

An external fault detected by the drive, signaling an issue with a device connected to the external fault input terminals, specifically S1. The fault code (EF0-EF8) may indicate different external fault conditions defined by the user or manufacturer.

• Fault condition from an external safety device (e.g., thermal overload, emergency stop switch, limit switch)
• Incorrect wiring or loose connection to the S1 terminal, leading to an unintended fault signal
• Faulty external sensor or switch providing the fault signal to the drive.

1. 1

   Inspect all external devices connected to the S1 terminal for their operational status and reset any tripped devices.

2. 2

   Verify the integrity of wiring connections to the S1 terminal and check for continuity.

3. 3

   Measure the voltage signal at the S1 terminal to ensure it is within the expected range (e.g., 24VDC when the fault is clear).
