Communication Error (ECM)

What does P mean?

A communication error occurred between Energy Charge Module (ECM) units or with connected devices. This indicates a problem in the data exchange between the ECM's Control Module (A06B-6158-H010) and other connected units like the Servo amplifier or PMC.

• Loss of communication with the Electronic Control Module (ECM).
• Faulty wiring or connector to the ECM.
• ECM internal fault.
• Interference on the communication bus.

1. 1

   Immediately stop the machine using the emergency stop button and open the external Main Circuit Contactor (MCC) of the Power supply.

2. 2

   Inspect all communication cables (e.g., K21, K24 on page 575) connecting the ECM Control Module to other modules (Servo amplifier, I/O) for secure connections and physical damage.

3. 3

   Verify the communication settings and parameters in the ECM Control Module and connected devices to ensure they are correctly configured.

4. 4

   Check for external electrical noise that could interfere with communication signals; ensure signal lines are properly shielded and separated from power lines (Section 5.3, page 108).

5. 5

   Ensure that all connected modules are powered on in the correct sequence, as incorrect timing can lead to communication issues.
