¿Qué significa b ?
The circuit responsible for controlling the current of the Energy Charge Module (ECM) has malfunctioned. This is a critical internal fault within the ECM Control Module (A06B-6158-H010), affecting its ability to manage charge and discharge currents, leading to unstable operation.
Causas comunes
- Failure in the current control feedback loop within the ECM.
- Faulty current sensor reading.
- Issues with motor phase current detection.
- ECM control signal inconsistency to motor driver.

- 1
Immediately stop the machine using the emergency stop button and open the external Main Circuit Contactor (MCC) of the Power supply.
- 2
Inspect the ECM Control Module (A06B-6158-H010) for any visible signs of damage, such as burnt components, discolored areas, or loose internal connections.
- 3
Check the input power supply to the ECM Control Module for stability and correct voltage levels.
- 4
Verify that all internal connections and wiring within the ECM Control Module, particularly those related to current sensing and control, are secure.
- 5
If no external factors or loose connections are identified, the ECM Control Module (A06B-6158-H010) is likely faulty and requires replacement.
