EEr External monitoring (activated via DCTRL)

Was bedeutet x091 ?

An external monitoring function has triggered this fault, which is activated via DCTRL (Drive Control) and configured through parameter C0581. The 'x' in the code indicates the response type: 0 for TRIP, 1 for message, 2 for warning.

• The external safety circuit (e.g., E-Stop, light curtain, guard door switch) connected to a digital input configured for external monitoring has opened.
• A signal on a digital input configured as an external fault input via parameter C0581 has changed state, triggering the fault.
• Wiring fault (e.g., broken wire, short circuit) in the external monitoring circuit connected to the drive.
• External PLC or control system outputting an incorrect signal to the drive's external monitoring input.
• Incorrect configuration of parameter C0581, where a normally closed contact is expected but an open contact is provided.

1. 1

   Identify the specific digital input assigned as the external monitoring input via parameter C0581 and measure its voltage state.

2. 2

   Trace the wiring from the identified digital input to the external monitoring device (e.g., E-stop button, safety relay contact).

3. 3

   Verify the status of all external safety devices and ensure their contacts are closed (or open, as configured) as expected.

4. 4

   Check the logic configured in parameter C0581 (e.g., active high or active low) and ensure it matches the external signal.

5. 5

   Perform a continuity test on the external monitoring circuit wiring to identify any breaks or short circuits.
