Over Voltage Fault

What does 05 mean?

This fault signifies that the DC Bus voltage has exceeded its maximum limit during operation. For 200-240V AC rated controllers, this trip occurs at 410V DC bus (290V AC incoming); for 380-460V AC rated controllers, it's 815V DC bus (575V AC incoming). This often happens due to motor regeneration, which can put excessive stress on the controller's internal components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Consider installing a dynamic brake module to dissipate excess energy.

2. 4

   As an alternative, install an external capacitor module to absorb regenerated energy.
