GUNTHER Product Lines We Repair
Our engineers are trained on the full GUNTHER product range. Below are the major product families we service.
GUNTHER Servo Control Modules
Precision servo controllers and motion control amplifiers for multi-axis automation. Common issues include encoder feedback drift, capacitor degradation in power stages, and firmware corruption affecting axis synchronization and positioning accuracy.
GUNTHER Programmable Logic Controllers (PLC)
Modular PLC systems for industrial automation and real-time process control. Repair challenges include memory module failures, I/O card burnout from surges, communication port degradation, and ladder logic ROM corruption.
GUNTHER Electromechanical Relay Modules
Industrial-grade relay banks, contactor modules, and electromechanical switching arrays. Typical faults involve relay coil burnout, contact pitting, mechanical armature stiction, and solder joint fatigue in high-vibration environments.
GUNTHER Pneumatic & Hydraulic Valve Controllers
Proportional and directional solenoid valve drivers for fluid power systems. Common defects include solenoid coil insulation breakdown, valve spool stiction, pressure transducer failures, and response lag due to capacitor aging.
GUNTHER Motor Soft Starters & Reduced-Voltage Controllers
Three-phase motor starting systems with ramp control and bypass contactors. Repair issues stem from thyristor gating circuit failure, heat sink thermal degradation, phase loss detection faults, and control PCB connector corrosion.
GUNTHER Digital Operator Panels & Human-Machine Interfaces
Industrial touchscreen and hardwired HMI panels for machine control and process monitoring. Failures include display backlight degradation, touch sensor calibration loss, firmware crashes, and serial communication timeouts.
Why Choose Synchronics for GUNTHER Repairs?

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 GUNTHER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GUNTHER equipment arriving at our workshop.
- ✓GUNTHER servo controller position drift and axis misalignment — Encoder feedback signal degradation due to connector corrosion, cable shielding compromise, or internal quadrature counter overflow in long-runtime cycles. Temperature fluctuations also cause drift in analog reference circuits.
- ✓GUNTHER PLC memory module failure and ladder logic loss — Battery-backed RAM cells degrade after 5-7 years; backup battery sulfation prevents data retention. Program corruption also occurs from power surges or improper shutdown during firmware upload.
- ✓GUNTHER relay module contact pitting and electrical chatter — Arc erosion during inductive load switching (motors, solenoids) causes contact surface degradation. High vibration environments accelerate mechanical wear and reduce contact pressure.
- ✓GUNTHER proportional solenoid valve coil burnout — Continuous energization at full current without pulse-width modulation protection. Contamination in coil insulation and thermal stress from repeated pressure cycling degrades winding resistance.
- ✓GUNTHER soft starter thyristor gate drive circuit failure — Damp heat in industrial environments corrodes optocoupler LEDs in gate drive circuits. Voltage spikes from motor starting transients also degrade gate drive transformers and phase-shift capacitors.
- ✓GUNTHER HMI touchscreen display dimming and frozen screens — LED backlight degradation in 7-10 year old panels; electrolytic capacitors in driver circuitry dry out, causing voltage sag. Firmware memory corruption also freezes screen response to inputs.

Frequently Asked Questions — GUNTHER Repairs
Do you repair GUNTHER equipment anywhere in India?+
Yes. Synchronics repairs the full GUNTHER product range — servo controllers, PLCs, relay modules, proportional valve drivers, soft starters, and HMI panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other major cities. All repairs are completed at our state-of-the-art facility in Vadodara, Gujarat, with same-day diagnostics.
Can you recover a GUNTHER PLC that has lost its ladder logic program?+
Yes, Synchronics can often recover GUNTHER ladder logic in two ways: (1) if your plant has a backup program file, we reload it into the PLC after replacing failed memory modules, or (2) if no backup exists, we use EPROM extraction and ROM dumping techniques to recover partial program code. We always recommend maintaining offline program backups. Contact us with your PLC model number for recovery feasibility.
What is the typical turnaround time for GUNTHER servo controller repair?+
Standard turnaround for GUNTHER servo modules is 5-7 business days including diagnostics, component replacement, bench testing, and calibration. Express service (3-4 days) is available for critical production equipment. We perform full encoder signal verification, axis synchronization testing, and load simulation before release. Quotes provided within 24 hours of equipment receipt.
Do you stock GUNTHER replacement parts and modules?+
Synchronics maintains inventory of common GUNTHER replacement components including relay coils, solenoid assemblies, servo encoder modules, memory backup batteries, and electrolytic capacitors. For specialized modules (GSC-2000, GLC-200, GOP panels), we source directly from GUNTHER distributors or perform component-level repairs. Lead times for sourced modules typically 7-10 days. Priority stock items ship within 48 hours.
How do I know if my GUNTHER soft starter needs repair versus replacement?+
Synchronics diagnoses soft starter health by checking thyristor switching stability, gate drive circuit voltage levels, and phase-shift capacitor ESR. If 60-70% of the unit is functional, cost-effective component replacement restores operation. If multiple thyristor stacks are damaged or power section shows thermal degradation, replacement is recommended. Full diagnostic cost is Rs. 1,500-2,500; we waive it if you authorize repair.
How do I send my GUNTHER 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 GUNTHER 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 GUNTHER 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 GUNTHER 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.
