Overvoltage

¿Qué significa 5 ?

The DC bus voltage has exceeded its maximum permissible value. This can be caused by high incoming AC line voltage, transient voltage spikes, or regenerative energy from a decelerating motor, risking damage to the drive's DC bus capacitors.

• DC bus voltage exceeds the overvoltage limit.
• Regenerative braking energy is not being dissipated effectively.
• Input line voltage is too high.
• Faulty braking chopper or resistor (if applicable).

1. 1

   Monitor the incoming AC line voltage for high voltage conditions or transient spikes.

2. 2

   Extend the deceleration time (e.g., by increasing the deceleration ramp parameter).

3. 3

   Install a dynamic brake option (resistor and chopper circuit) to dissipate regenerative energy.
