ROCKWELL Product Lines We Repair
Our engineers are trained on the full ROCKWELL product range. Below are the major product families we service.
ControlLogix and CompactLogix PLC Family
Rockwell's flagship programmable logic controllers used for process control and discrete manufacturing. Common failures include power supply module burnout, Ethernet port damage, memory corruption, and I/O card faults. Synchronics restores these to factory specification with full testing.
PowerFlex Variable Frequency Drives
Rockwell's three-phase AC drives for motors ranging 0.75 kW to 500+ kW. Typical issues: IGBT gate driver failure, DC bus capacitor degradation, cooling fan motor burnout, and firmware crashes. Synchronics rebuilds power stages and reprograms drive parameters.
Allen-Bradley Kinetix Servo and Motion Control
Precision servo drives and motion controllers for synchronous machine operation and robotic arms. Failures include encoder interface loss, PWM circuit degradation, and axis commissioning lockouts. Synchronics diagnoses motion faults and restores control loop stability.
Stratix Industrial Ethernet Switches and Routers
Rockwell managed and unmanaged switches for factory floor networking. Common issues: port burnout from surges, firmware corruption, redundancy ring failures, and MAC table overflow. Synchronics restores network connectivity and industrial protocol support.
PanelView Industrial HMI Terminals
Allen-Bradley touchscreen and button-based operator interfaces for machine visualization. Typical repairs: LCD backlight failure, touch sensor unresponsiveness, memory chip corruption, and power supply malfunction. Synchronics replaces components and restores operator access.
GuardLogix Safety-Rated Controllers
Rockwell SIL 3 certified safety PLCs for hazardous environments and emergency stop logic. Issues include safety-rated input module failure, diagnostic LED malfunction, and loss of redundancy. Synchronics performs full SIL compliance re-certification.

Common ROCKWELL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ROCKWELL equipment arriving at our workshop.
- ✓ControlLogix 1756-PA75 Power Supply Failure — Electrolytic capacitor dry-out due to high ambient factory temperatures (45-50°C) and continuous operation without thermal management. Capacitor ESR rises, voltage regulation fails, and the supply shuts down.
- ✓PowerFlex Drive IGBT Gate Driver Circuit Failure (Fault Code F-07) — Moisture ingress or solder joint micro-fractures on the gate driver PCB from thermal cycling in Indian monsoon climates. Gate drive voltage drops below 9V, IGBTs fail to switch, and the drive faults with overvoltage shutdown.
- ✓Kinetix Servo Drive Encoder Interface Loss (Fault Code 16#3220) — Differential encoder signal wiring damaged due to cable flex fatigue or contamination of the incremental encoder connector. Synchronics detects zero encoder counts during commissioning.
- ✓CompactLogix Ethernet Port Malfunction after Network Surge — ESD or lightning transient damages the Ethernet PHY IC (typically 100BASE-TX transformer and magnetics) despite industrial surge protection devices. Port LEDs remain dark and the controller cannot reach network.
- ✓PanelView 5500 LCD Backlight Failure and Ghosting — CCFL (cold cathode fluorescent lamp) or LED backlight string fails after 30,000+ operating hours; inverter circuit capacitors age and fail to supply correct sustaining voltage. Screen dims or flickers randomly.
- ✓Stratix 5400 Managed Switch Redundancy Ring Failure — Ring topology breaks when a single port fails or cable is unplugged; RSTP (Rapid Spanning Tree) recalculation halts data flow for 5-30 seconds, causing coordinated motion errors in synchronized systems.

Frequently Asked Questions — ROCKWELL Repairs
Do you repair Rockwell Automation equipment anywhere in India?+
Yes. Synchronics repairs all Rockwell Automation product ranges — CompactLogix, ControlLogix, PowerFlex drives, Kinetix servo systems, GuardLogix safety PLCs, PanelView HMIs, and Stratix networking equipment. We offer same-day PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and over 100 other cities. All repairs are performed in our ISO 9001 certified facility in Vadodara, Gujarat. Standard turnaround is 5-7 working days.
What is your expertise with Rockwell PowerFlex drive repairs?+
Synchronics has repaired over 2,000 PowerFlex drives (models 70, 4M, 525, 750-Series, 700H, 700S) across Indian textile mills, automotive plants, and cement facilities. We specialize in: IGBT stage replacement, DC bus capacitor bank reconstruction, gate driver IC substitution, firmware restoration, parameter re-commissioning, and full motor load testing. We maintain stock of critical power components and typically restore drives to full rated output within 5 days. Unlike OEM service, we diagnose root cause and upgrade components to prevent recurrence.
Can Synchronics repair a ControlLogix PLC that has failed power supply and corrupted program memory?+
Yes. ControlLogix dual faults are common in Indian factories due to voltage instability and thermal stress. Synchronics first replaces the power supply module (1756-PA75 or PA85), then performs data recovery from the PLC's backup memory or from the customer's documented program. We re-flash the memory, validate all I/O addressing, perform cold and hot start cycles, and test with a simulated load before shipping. Full repair typically takes 5-6 working days.
Do you stock Rockwell PLC and drive components or only repair and return originals?+
Synchronics repairs and restores original Rockwell modules whenever possible — this preserves your system configuration and avoids compatibility issues. However, for components with scarcity or extended lead times (example: 1756-PA75 power supplies, Kinetix servo encoder modules), we maintain strategic inventory and can install genuine industrial-grade equivalents with full functional warranty. All replacement components undergo the same 48-hour burn-in and test protocol as repaired units.
What warranty and support do you provide for Rockwell equipment repairs?+
Every Rockwell device repaired by Synchronics carries a 12-month functional warranty covering parts and labor. We provide free remote troubleshooting support during the first 30 days post-repair via WhatsApp, phone, or video call. Warranty covers component failure but excludes damage from incorrect installation, improper voltage input, or physical impact. We also issue detailed repair reports with replaced components, test results, and commissioning notes so your engineering team understands the fault origin and preventive measures.
How do I send my ROCKWELL 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 ROCKWELL 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 ROCKWELL 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 ROCKWELL 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.
