Servo Drive Repair
Servo amplifier and axis module repair for Canada and the USA
- Free evaluation
- 24–72 hr typical
- 12-month warranty
- Tested on our jigs
Short answer
Can a servo drive be repaired?
Yes. Most failed servo drives and amplifiers can be repaired at component level for a fraction of the price of a new unit. We find the root cause, replace the failed parts, then run the drive with a motor on our own test jigs before it ships back with a test report and a 12-month warranty.
What we repair
What we repair on a servo drive
Power stage & IGBTs
Shorted IGBT and IPM modules, gate drivers and snubber parts replaced, then the stage is tested under power.
DC bus & capacitors
Aged or leaking bus capacitors, pre-charge circuits and braking transistors.
Control & regulator boards
Processor, memory and regulator board faults diagnosed and repaired at component level.
Feedback interface
Encoder and resolver input circuits behind feedback, position and overspeed faults.
Internal power supply
Switch-mode supplies that leave a drive dead, rebooting or with a blank display.
Communication & I/O
Fieldbus, DRIVE-CLiQ, SERCOS and I/O interface faults.
Diagnosis guide
Common servo drive faults we fix
Trips on overcurrent as soon as the axis is enabled
Shorted IGBT or IPM module, failed gate driver, or a damaged motor cable
DC bus overvoltage when the axis decelerates
Failed braking transistor or resistor circuit, or bus voltage sensing fault
Undervoltage or pre-charge fault at power-up
Pre-charge circuit, bus capacitors or the incoming line supply
Overtemperature or overload after running a while
Failed cooling fan, clogged heat sink or degraded power devices
Encoder or feedback errors with a known-good motor
Damaged feedback input circuit or communication interface on the drive
No display, dead or rebooting
Internal switch-mode power supply or control board failure
Quality
How we test every repaired servo drive
Parts replaced is not the same as fixed. Every unit is proven under power before it leaves our Mississauga, Ontario repair centre.

Photos and condition report when the drive arrives
- 02
Root cause found before we quote, not just the blown part
- 03
Run under power with a motor on our own test jigs
- 04
Test report ships with every repaired drive

Servo drive repair questions
How long does a servo drive repair take?
Typical turnaround is 24–72 hours once you approve the quote. Exchange units usually ship within 1–2 business days of receiving your unit.
Is the evaluation free?
Yes. We power up and test the drive, find the root cause and send a written quote. No work starts without your approval.
How do you test a repaired servo drive?
Every repaired drive is run under power with a motor on our own test jigs, and a test report ships with the unit.
Do you repair obsolete servo drives?
Yes. We repair discontinued drives at component level, so proven machines keep running after the manufacturer stops support.
What warranty comes with the repair?
Every servo drive repair comes with a 12-month warranty.
