External fault 1

Was bedeutet 9081 ?

An external device configured as External Event 1 (parameters 31.01 and 31.02) has generated a fault. This indicates a problem with equipment or sensors outside the drive's direct control, potentially impacting the entire system's operation and requiring immediate attention.

• Digital input configured as External Event 1 (P31.02) losing its expected state (e.g., opening a normally closed contact).
• External safety device (e.g., emergency stop, guard interlock, thermal overload relay) tripping and sending a fault signal to the drive.
• Failure of an auxiliary contact on a motor starter or overload relay, opening the drive's fault input circuit.
• Loose or broken wiring connection for the digital input linked to P31.02, leading to an incorrect state (e.g., open circuit).
• Incorrect parameter setting for P31.02 (DI Config) causing the drive to misinterpret the input state (e.g., expecting N.O. when N.C. is connected).

1. 1

   1. Identify the digital input terminal (e.g., DI1, DI2) configured as External Event 1 in P31.02 (DI Config).

2. 2

   2. Measure the voltage at the identified digital input terminal relative to common (e.g., 24VDC or 0VDC) to confirm its current state.

3. 3

   3. Inspect the external device (e.g., E-stop button, thermal overload contact) connected to this input for proper operation and reset if tripped.

4. 4

   4. Verify the integrity of the wiring from the external device to the drive's digital input terminal, checking for opens or shorts using a multimeter.

5. 5

   5. Review P31.02 (DI Config) to ensure the input polarity (e.g., Normally Open or Normally Closed) is correctly configured for the external device.
