This manual provides a system description and start-up guide for ABB ACS800-67 wind turbine converters. It covers the system components, converter system architecture, control of generator power, operating speed ranges, torque and reactive power control, and interfaces. It also details start-up procedures for low and medium voltage stators, practical examples for setup, and troubleshooting of warnings, limits, and faults.
Troubleshooting and error codes
| Fault | Cause | What to do |
|---|---|---|
| Pulse encoder pulses or zero pulse are missing or wrong | Generator overcurrent fault Speed / position / RTAC module fault |
If the encoder is of unisolated type, check that the cable is grounded only on converter side. In case of wrong encoder direction, check the pulse encoder phasing (A/B channels). Check the type and connection of the encoder; differential encoder is recommended. |
| Current value is wrong. Torque actual value does not correspond to the reference value. |
Faulty current transformer inside power module | Check the current transformer. Check the values in parameter group 99. |
| There is reactive power without reference. | Wrong values in parameter group 99 in the rotor-side converter control program | Check the values in parameter group 99. |
| Torque oscillates and overcurrent fault occurs. | ||
| Current imbalance fault | ||
| Earth fault |
