Analog output 2 fault

What does 28834 mean?

An open circuit or short circuit condition has been detected at analog output 2. This could prevent proper signal transmission to connected devices.

• Open circuit in the wiring connecting Analog Output 2 (e.g., X4.3, X4.4) to the external receiving device.
• Short circuit between the Analog Output 2 signal line and ground, or another adjacent conductor.
• The input of the connected receiving device is shorted internally, placing an excessive load on Analog Output 2.
• Overload on Analog Output 2 due to an improper load impedance, drawing current beyond the output's rating.
• Sustained overvoltage or overcurrent conditions on Analog Output 2 leading to component failure.

Click steps to track your progress.

1. 1

   Isolate Analog Output 2 by disconnecting the load and measure the voltage or current at terminals (e.g., X4.3, X4.4) with a multimeter.

2. 2

   Test the continuity of the wiring from Analog Output 2 to the receiving device to check for breaks or short circuits.

3. 3

   Measure the input impedance of the device connected to Analog Output 2 to ensure it is compatible with the drive's output capabilities.

4. 4

   Apply a specific command value to Analog Output 2 (e.g., 5V, 12mA) and observe the actual output signal with a multimeter.

5. 5

   Verify proper grounding and shielding practices for the Analog Output 2 signal cable to prevent induced shorts or current loops.
