External Fault at Terminal S6

Was bedeutet EF6 ?

This fault is triggered when an external condition connected to multi-function digital input terminal S6 activates the Drive's external fault function, causing the Drive to stop. It indicates an issue with the external device or process monitored by S6, which could lead to machine downtime or safety risks if misidentified.

• Activation of a monitored external condition by a sensor or switch connected to digital input S6.
• Loose or corroded connection at terminal S6 or at the external device's connection point.
• Incorrectly set parameter H1-06 (S6 function selection) for the associated external fault input.
• Faulty external switch or sensor providing a continuous or intermittent fault signal.
• Electromagnetic interference (EMI) causing spurious activation of the S6 input.

1. 1

   Determine the function assigned to terminal S6 (e.g., H1-06 setting) and identify the corresponding external device.

2. 2

   Check the electrical state of terminal S6 using a multimeter (e.g., 24VDC or 0VDC relative to SN) to confirm the input status.

3. 3

   Examine all connections and wiring associated with S6, including intermediate terminal blocks, for integrity and proper shielding.

4. 4

   Test the operation of the external device connected to S6, verifying its contacts open and close as expected.

5. 5

   Temporarily reconfigure parameter H1-06 to a non-fault function (e.g., 'Run Forward') to isolate if the Drive's input is faulty.
