RMG Equipment We Repair — By Category
RMG Product Lines We Repair
Our engineers are trained on the full RMG product range. Below are the major product families we service.
RMG Servo Drives & Amplifiers
High-precision servo amplifiers for proportional and directional control valves. Common failures include capacitor degradation, IGBT module breakdown, feedback signal loss, and gate drive faults. Thermal stress and contaminated hydraulic fluid accelerate component wear.
RMG Proportional Valve Controllers
Electronic proportional and directional control valve modules with integrated feedback compensation. Repair focuses on solenoid driver circuits, pressure transducer faults, and PID loop instability causing oscillation and slow response.
RMG Closed-Loop Servo Systems
Integrated servo control units combining hydraulic proportioning with electronic feedback for precision positioning. Common issues include encoder cable degradation, servo loop instability, pressure relief valve electronics failure, and loss of proportional command signal.
RMG Fieldbus & Industrial Ethernet Interfaces
CANopen, Profibus, and EtherCAT gateway modules for RMG motion control integration into plant automation networks. Failures stem from poor EMI shielding, corroded connector pins, firmware corruption, and communication timeout loops.
RMG Pressure & Sensor Electronics
Pressure transducer signal conditioning, load cell amplifiers, and sensor bridge electronics for closed-loop hydraulic control. Common repairs address zero drift, span errors, 4-20mA output faults, and transducer connector oxidation.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common RMG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in RMG equipment arriving at our workshop.
- ✓RMG servo amplifier capacitor bank failure — Electrolytic capacitors in RMG power supply and gate drive circuits degrade prematurely due to India's high ambient temperature, humidity, and industrial dust ingress. Surge spikes from motor switching and hydraulic pressure transients accelerate breakdown.
- ✓RMG proportional solenoid driver IGBT short circuit — Gate oxide breakdown in IGBT modules occurs due to inadequate snubber network filtering or reverse EMF spikes from proportional solenoid coil collapse. Thermal cycling and vibration-induced solder fatigue on PCB pads initiate failure chains.
- ✓RMG closed-loop servo feedback signal loss — Encoder cable shield corrosion, intermittent connector contacts, and twisted-pair unraveling introduce noise into feedback loops. RMG signal conditioning circuits lose lock, triggering servo oscillation and proportional valve hunting.
- ✓RMG proportional valve spool position transducer drift — LVDT coil contamination, ferrite core cracking, and secondary winding insulation breakdown cause signal offset and non-linearity. Hydraulic fluid oxidation products and metal wear particles settle around LVDT electronics, degrading coupling.
- ✓RMG CANopen/Profibus interface communication timeout — Corroded RS485 connector pins, EMI from nearby servo motor cables, and firmware version incompatibility cause periodic frame loss. Termination resistor failure or floating CAN bus state triggers RMG gateway card faults.
- ✓RMG pressure transducer amplifier 4-20mA output stuck or drifting — Op-amp input offset drift due to temperature variation, failed precision resistor network tolerance, and leaking coupling capacitors cause analog output error. Transducer cable ground loop contamination injects noise into measurement signal chain.

Frequently Asked Questions — RMG Repairs
Do you repair RMG equipment anywhere in India?+
Yes. Synchronics repairs the complete RMG product range—servo drives, proportional valve controllers, closed-loop servo systems, and fieldbus gateway modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Jaipur, and all metro and industrial cities. Single repair facility in Vadodara, Gujarat ensures consistent quality and fast turnaround.
What RMG fault codes do you troubleshoot and repair?+
Synchronics diagnoses RMG servo module error codes including servo loop timeout, feedback signal loss, pressure relief fault, solenoid driver overload, CAN/Profibus communication error, and transducer out-of-range. We cross-reference RMG documentation, perform functional testing on our lab benches, and return equipment with full fault history and repair summary.
Can Synchronics repair RMG proportional valve electronics without OEM spare parts?+
Yes. For aged RMG proportional controllers, we source cross-compatible industrial components (capacitors, op-amps, IGBT modules, resistor networks) and rebuild PCBs to OEM functional specification. We test repaired modules on our proportional valve test rig under simulated load before returning. This approach reduces cost and lead time compared to original RMG spare modules.
How long does RMG servo drive repair typically take?+
Standard RMG servo amplifier repairs (capacitor replacement, IGBT module swap, connector cleaning) take 5-7 working days. Complex issues like LVDT feedback sensor replacement or proportional spool calibration may require 8-12 days. We provide same-day pickup and expedited repair options for critical production equipment. Contact our service desk for latest turnaround estimate.
Do you offer RMG preventive maintenance and test reports?+
Yes. Synchronics provides RMG equipment health checks, thermal imaging of power supply stages, capacitor ESR measurement, solenoid coil resistance testing, feedback loop oscilloscope analysis, and pressure transducer calibration verification. Full test reports with photographs and trend data guide future maintenance planning. Preventive service extends RMG equipment life and reduces unplanned downtime.
How do I send my RMG 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 RMG 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 RMG 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 RMG 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.
