Abnormal Charge of Capacitor Module (ECM)

Hva betyr E ?

The Energy Charge Module's (ECM) Capacitor Modules are not charging normally. This indicates a failure in the charging process, possibly due to a fault in the Capacitor Module itself (A06B-6158-H020), the charging control circuit, or insufficient power supply.

• Abnormal charging behavior of the capacitor module (ECM).
• Faulty charging circuit within the ECM.
• Capacitor module (ECM) leakage current exceeds acceptable levels.
• External influences causing erratic charging profiles.

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 the Capacitor Modules (A06B-6158-H020) for any visible damage or signs of malfunction, such as bulging or leakage.

3. 3

   Check the connections between the ECM Control Module (A06B-6158-H010) and the Capacitor Modules for secure contact and continuity.

4. 4

   Verify the functionality of the DC Reactor (A06B-6158-H040), which smooths the charge and discharge current (page 578).

5. 5

   Measure the input power to the ECM to ensure it meets the requirements for charging the capacitor modules.
