Cause : OverVoltage. DC-link voltage (r0026) exceeds the overvoltage threshold (refer to parameter r0026)
Diagnosis & Remedy
Check the following:
- Supply voltage (P0210) must lie within limits indicated on rating plate .
- DC-link voltage controller must be enabled (P1240) and parameterized properly.
- Extend the deceleration ramps (ramp-down time P1121, P1135)
- Remove the ground fault
- Required braking power must lie within specified limits.
- Check the feeder cable to the braking resistor
- Check the technical data of the braking resistor
- Check the load duty cycle of the braking resistor with reference to the application
