Fault code

INVT GD200A OV1 Over-voltage when acceleration

Possible causes

  • The input voltage is abnormal.
  • There is large energy feedback.
  • No braking components.
  • Braking energy is not open.

Recommended checks and actions

  • Check the input power.
  • Check if the DEC time of the load is too short or the inverter starts during the rotation of the motor or it needs to increase the energy consumption components.
  • Install the braking components.
  • Check the setting of relative function codes.
