Repair Services
We Fix What Others Can't
Component-level repair for every major category of industrial electronics — diagnosed properly, tested under load, and returned with a warranty.
Eindotech Autovolt handles the full range of industrial electronics repair. Whether it is a drive fault that shut down your line, a PLC that stopped communicating, or an HMI with a dead screen — we diagnose at component level, repair to spec, and test before dispatch.

AC Drives & DC Drives
We repair AC variable speed drives and DC drives at component level — power stage faults, IGBT failures, gate driver issues, control board faults, and communication errors. All units are load tested before return.
- AC variable speed drives
- DC drives and controllers
- IGBT and power stage repair
- Gate driver and control board repair
- Full load rig testing before dispatch
All brands. Component-level repair.
Variable Frequency Drives (VFDs)
VFD faults are rarely simple. We go beyond surface-level checks — replacing power modules, rebuilding capacitor banks, repairing control cards, and resolving firmware or communication issues that others miss.
- All major VFD brands covered
- IGBT and power module replacement
- Capacitor bank rebuild
- Control card and keypad repair
- Parameter backup where possible
Precision repair for motion-critical systems
Servo Drives & Servo Motors
Servo faults affect accuracy, not just availability. We repair servo drive amplifiers and servo motor systems for CNC machines, robotics, and automation lines — restoring the precision your process depends on.
- Servo drive amplifier repair
- Servo motor fault diagnosis
- Encoder and feedback system repair
- CNC and robotics servo systems
- Functional motion testing
Your control logic, restored
PLCs & Industrial Controllers
PLC failures can bring an entire line to a halt. We repair CPU modules, I/O cards, communication modules, and power supply units across all major PLC platforms — with full functional verification after repair.
