Over-current of Discharge Current (ECM)
Fanuc · Macro B CNC Programming
¿Qué significa 4 ?
An over-current occurred in the discharge current from the Energy Charge Module's (ECM) Capacitor Modules. This suggests an issue with the energy being released, possibly due to a fault in the ECM's discharge circuit, the Resistor Module (A06B-6158-H030), or an external short circuit drawing excessive power.
Causas comunes
- The discharge current exceeds its maximum allowed limit.
- Short circuit in the discharge path.
- Faulty discharge components leading to high current draw.
- Overload condition during discharge cycle.
Pasos de reparación & Lista de verificación

- 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 wiring of the discharge circuit between the ECM Control Module and the Resistor Module for any short circuits or damage.
- 3
Verify the integrity of the Resistor Module (A06B-6158-H030), ensuring its resistance (expected 30 ohm, page 578) is within specification and it shows no signs of overheating.
- 4
Check the Capacitor Modules (A06B-6158-H020) for internal faults that could cause uncontrolled discharge.
- 5
Ensure that the external load connected to the ECM is not drawing excessive current during discharge operations, which could trigger this alarm.
