DGR Product Lines We Repair
Our engineers are trained on the full DGR product range. Below are the major product families we service.
DGR Servo Amplifiers (SPA/SPB Series)
High-performance brushless servo drives for positioning and continuous motion applications. Common faults include encoder signal loss, parameter corruption, and thermal shutdown due to inadequate cooling in high-ambient textile mills and foundries.
DGR Frequency Converters (FCI Series)
AC frequency inverters for asynchronous motor speed control in conveyor systems and pump applications. Typical failures involve DC bus capacitor ripple, IGBT gate drive faults, and EMC filter degradation from moisture ingress in humid coastal facilities.
DGR Motion Control Modules (MCM Series)
Programmable logic modules for synchronized multi-axis motion in packaging and textile machinery. Repair needs include CANopen node failures, analog-to-digital converter drift, and firmware corruption from power interruptions.
DGR Encoder Feedback Modules (EFM Series)
Incremental and absolute encoder interface cards for closed-loop speed feedback. Prone to connector corrosion, optocoupler aging, and SSI protocol timing errors in vibration-heavy steel rolling mills.
DGR Soft-Start Controllers (SSC Series)
Thyristor-based inrush current limiters for large motor starting in cement, paper, and sugar plants. Failures stem from thyristor leakage, snubber capacitor breakdown, and phase-control circuit oscillation.
Why Choose Synchronics for DGR Repairs?

We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on DGR equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common DGR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DGR equipment arriving at our workshop.
- ✓DGR SPA Servo Encoder Signal Loss Error — Incremental encoder cable shielding degradation or connector oxidation in humid factory environments. Vibration-induced micro-disconnects also common in textile spindle drives.
- ✓DGR FCI Inverter DC Bus Over-Voltage Shutdown — Electrolytic capacitor ripple current elevation or regenerative braking energy from sudden motor deceleration without load dump resistor. Common in packaging machinery with frequent start-stop cycles.
- ✓DGR MCM CANopen Heartbeat Timeout — Corrupted device firmware after intermittent power loss or defective CAN termination resistors causing bus contention. Symptom: E_MCM_001 error code with loss of multi-axis synchronization.
- ✓DGR Soft-Start SSC Thyristor Leakage Current — Thermal cycling in SCR gates causes minority carrier leakage, especially in high-ambient cement and steel facilities. Uncontrolled inrush current results despite control signal absent.
- ✓DGR Frequency Converter Spurious EMI Fault Reset — Inadequate EMC filter grounding or loose cable gland seals allowing RF noise coupling into analog inputs. Symptom: random shutdown and restart in switchgear cubicles with VFDs stacked vertically.
- ✓DGR EFM Absolute Encoder SSI Protocol Error — Clock pulse timing skew or phase-shift in SSI decoder IC due to aging capacitors or PCB trace corrosion near connector. Symptom: garbled multi-turn position data causing homing failure.

Frequently Asked Questions — DGR Repairs
Do you repair DGR equipment anywhere in India?+
Yes. Synchronics repairs the full DGR product range — servo amplifiers, frequency inverters, motion control modules, encoder interfaces, and soft-start controllers. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other cities via our logistics network. All repairs completed in our flagship facility in Vadodara, Gujarat with 28+ years DGR expertise.
What is the typical turnaround time for DGR servo drive repair?+
Standard DGR servo amplifier (SPA/SPB series) repairs take 5-7 working days including component sourcing, power stage testing, encoder calibration, and parameter upload. Express service available for textile and automotive customers — 48-72 hour turnaround for firmware reload and connector repairs. We maintain stock of critical DGR servo boards in Vadodara facility.
Do you stock original DGR spare parts or use aftermarket components?+
Synchronics uses genuine DGR replacement components for all critical repairs — IGBT modules, electrolytic capacitors, optocouplers, and firmware. For connector maintenance, we source DIN 43650 and M12 connectors meeting DGR specifications. We do not compromise on component quality; all parts are sourced through authorized DGR distributors or direct from Germany.
Can you repair DGR frequency converters (FCI series) with burnt IGBT modules?+
Yes. DGR FCI IGBT failure is common in high-temperature foundries and rolling mills. Synchronics replaces power stage modules with thermal compound re-application, tests gate drive circuits independently, and verifies DC bus stability before shipment. We also diagnose root cause — whether regenerative braking, inadequate heatsinking, or control signal fault — to prevent recurrence.
What diagnostic tools does Synchronics use for DGR motion control troubleshooting?+
Our 180+ engineers use DGR proprietary diagnostic software (MCM Commissioning Suite), oscilloscopes for CANopen signal verification, ESR meters for capacitor health, and parameter backup-restore tools via USB/Ethernet. We maintain calibrated test benches for DGR servo loop tuning and encoder feedback validation. Full diagnostic report provided with every repair.
How do I send my DGR unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a DGR drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on DGR repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your DGR unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
