Key features of our service
Common faults we repair
SERVOSTAR and AKD amplifiers report three-digit faults, with warnings shown under an n prefix. Bus, feedback and fieldbus faults are our most common AKD repairs.
- F401 – feedback configuration error (feedback type or parameters)
- F451 – feedback battery fault on an absolute encoder
- F501 – DC bus overvoltage (regeneration, braking resistor, supply)
- F502 – DC bus undervoltage (supply dip, soft-start circuit)
- F125 – fieldbus sync frames lost (EtherCAT or CANopen)
- F121 – homing error (sensor or homing configuration)
- Power stage (IGBT) failures on SERVOSTAR 600 and AKD drives
- Encoder and resolver feedback faults – cable break, supply, contamination
Why repair rather than replace?
Replacing a failed Kollmorgen servo drive, motion controller or automation component can be expensive, particularly when the original equipment is obsolete or difficult to source. Repairing the existing equipment can be a faster, more cost-effective solution while avoiding unnecessary replacement, reprogramming and commissioning.
- Repair is also the only option for obsolete and discontinued units, where a like-for-like replacement no longer exists. Where a repair is not economic, we say so and can supply a tested refurbished unit instead.
