Low-voltage of Capacitor Module (ECM)

¿Qué significa 8 ?

A low-voltage condition has occurred in the Energy Charge Module's Capacitor Modules. This indicates that the capacitor bank is not sufficiently charged or is discharging too rapidly, potentially due to a power supply issue, excessive load on the ECM, or a faulty capacitor module.

• Low voltage detected on the capacitor module (ECM) below P1-75 threshold.
• Inadequate power supply to the ECM.
• Capacitor module (ECM) internal fault causing voltage drop.
• External load drawing excessive current, reducing ECM voltage.

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

   Measure the voltage across the Capacitor Modules (A06B-6158-H020) to confirm the low-voltage condition.

3. 3

   Verify the input power supply to the ECM for stable voltage and adequate current to properly charge the capacitors.

4. 4

   Check for any abnormal load connected to the ECM that could cause rapid discharge of the Capacitor Modules.

5. 5

   Inspect the Capacitor Modules (A06B-6158-H020) for internal faults, such as leakage or degradation, that prevent them from holding charge.
