Over-current at Regeneration (ECM)

¿Qué significa 2 ?

An over-current of the DC link current occurred during motor deceleration (regeneration) as detected by the Energy Charge Module (ECM). This suggests that the regenerative energy is too high for the system to store or dissipate, potentially due to insufficient ECM capacity, rapid deceleration, or a fault in the regenerative circuit.

• Excessive current detected during regeneration (energy feedback).
• High back EMF from the motor during deceleration.
• Regeneration braking circuit unable to handle the current.
• Faulty regeneration control.

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

   Verify the capacity and functionality of the ECM's Capacitor Modules (A06B-6158-H020) and Resistor Module (A06B-6158-H030); ensure they are properly handling regenerated energy.

3. 3

   Check for any issues that could cause excessive regenerative energy, such as overly aggressive deceleration settings or external forces driving the motor.

4. 4

   Inspect the connections and components of the ECM's regenerative discharge circuit for any faults or damage.

5. 5

   If applicable, adjust the deceleration parameters of the motor in the CNC to reduce the regenerated energy and prevent overcurrent conditions.
