DC bus balancing monitor error

¿Qué significa F2836 ?

An error has been detected by the DC bus balancing monitor. This system ensures that the voltage across series-connected DC bus capacitors remains balanced. An imbalance can indicate a faulty capacitor, a problem with the balancing resistors, or an issue with the monitoring circuit itself, potentially leading to capacitor overvoltage and failure.

• Defective DC bus capacitor (e.g., increased ESR)
• Faulty balancing resistors across DC bus capacitors
• Problem with the DC bus voltage measurement circuitry
• Interference affecting the balancing monitor's readings
• Internal hardware fault in the balancing circuit

1. 1

   Verify drive parameters related to DC bus configuration and monitoring via the IndraDrive HMI or software.

2. 2

   Measure incoming AC supply phase-to-phase and phase-to-ground voltages at the drive input terminals to confirm stability, balance, and adherence to specifications.

3. 3

   Inspect all external DC bus connections (if applicable in multi-axis setups or with external braking units) for proper seating, torque, and signs of damage or corrosion.

4. 4

   Monitor the overall DC bus voltage and current values using the drive's diagnostic interface to observe for instability or deviations from expected levels under various load conditions.
