Servo Amplifier Repair & Diagnostics

Alarm-faulted, dead or repeatedly tripping servo amplifier? KONGRA separates the amplifier from motor, encoder, cabling, power and mechanical causes before recommending a costly module.

Do not condemn the amplifier from the alarm alone

Servo alarms can be caused by the amplifier, motor, encoder feedback, brake circuit, cabling, power quality, axis load or mechanical binding. Replacing the amplifier without isolating those conditions can damage the replacement or leave the fault unchanged.

KONGRA uses the supported machine documentation and observed conditions to define the failed subsystem.

  • Servo amplifier fault isolation
  • Motor and encoder context
  • Axis-load and mechanical context
  • Power and control conditions
  • Professional repair / rebuild / exchange options

Repair or exchange strategy

Where technically appropriate, a professionally repaired or exchange amplifier can reduce cost and lead time compared with a new module. KONGRA can coordinate sourcing and supported installation, parameter restoration and functional verification.

No manufacturer authorization, factory calibration or universal compatibility is implied. The exact control family and machine configuration must be reviewed.

FAQ

Frequently asked questions

Can an encoder fault look like a bad servo amplifier?+

Yes. Feedback, cabling, motor, brake and mechanical conditions can all affect servo behavior. The amplifier should be isolated from those causes before replacement.

Can you use an exchange servo amplifier?+

Where a suitable professional exchange source exists and the module is compatible, KONGRA can present that repair path for approval and handle the supported machine-side work.
