Ravel Equipment We Repair — By Category
Ravel Product Lines We Repair
Our engineers are trained on the full Ravel product range. Below are the major product families we service.
Ravel Compact PLC Range
Modular programmable logic controllers for textile, packaging, and food processing automation. Common issues include input/output card failures, memory corruption from power surges, communication port failures, and firmware lockouts after uncontrolled shutdowns.
Ravel SmartServo Drive Line
AC servo motor controllers for precision positioning in packaging, labeling, and converting machinery. Typical faults: encoder communication loss, over-temperature shutdowns, DC bus capacitor degradation, and firmware version conflicts affecting motion algorithms.
Ravel Axis Motion Controller
Multi-axis synchronized motion control for high-speed converting lines and rotary printing machines. Common failures include phase loss detection errors, encoder sync failures on slave axes, CAN-bus communication timeouts, and timing signal generation faults.
Ravel HMI Touch Panel Series
Industrial touchscreen interfaces for machinery operator control and diagnostics. Repair issues: display backlight LED failures, capacitive touch sensor drift, memory card read errors, and network ethernet port failures affecting remote monitoring.
Ravel PowerLink Inverter Range
Compact frequency inverters for motor speed control in Indian textile mills and pump stations. Common faults: IGBT module thermal runaway, DC bus voltage regulation failure, motor current sensing errors, and brake control relay sticking.

Common Ravel Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in Ravel equipment arriving at our workshop.
- ✓Ravel PLC Input Card Loss of Signal — Ravel RC-series controllers suffer input card failures when 24V supply rails experience voltage spikes from valve solenoid coils. Optocoupler chips degrade after repeated inductive kick transients common in textile mill solenoid valve circuits.
- ✓SmartServo Drive Encoder Synchronization Loss — Ravel SSD servo drives lose encoder reference after power interruptions during high-speed production runs. Incremental encoder index pulses fail to re-sync when servo firmware hangs during harsh motor deceleration or network communication dropout.
- ✓Ravel HMI Touchscreen Backlight Failure — The 24V DC LED backlight circuit in Ravel HMI-7T and HMI-10T panels fails when driver MOSFETs overheat due to poor thermal contact with aluminum backplate. Water ingress into the connector assembly accelerates corrosion of backlight power traces.
- ✓PowerLink Inverter DC Bus Overvoltage Shutdown — Ravel PL-series inverters experience DC bus capacitor aging in Indian hot mill environments—temperatures above 50°C degrade electrolytic capacity. Braking resistor faults cause regenerative voltage spikes that trigger protective shutdown on deceleration pulses.
- ✓Ravel AMC-4A Axis Synchronization Error on Slave Motors — Multi-axis Ravel AMC controllers lose slave axis timing when CAN-bus communication lines experience high EMI in Indian converting line environments. Slave encoder index pulses arrive out-of-phase with master encoder after network jitter exceeds firmware tolerances.
- ✓Ravel RC-Series Firmware Memory Corruption on Power Loss — Ravel compact PLC controllers experience non-volatile memory corruption when Indian sites experience multiple uncontrolled power cycles during brownouts or UPS battery depletion. EEPROM data becomes inconsistent, causing program lock-up or random output activation.

Frequently Asked Questions — Ravel Repairs
Does Synchronics repair Ravel equipment anywhere in India?+
Yes. Synchronics repairs the complete Ravel product portfolio—PLC controllers, servo drives, HMI touchscreens, motion axes, and frequency inverters. We offer pan-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all major industrial cities. All repairs are performed at our Vadodara facility with factory-level test equipment and genuine Ravel spares in stock.
What is the typical repair turnaround time for Ravel servo drives like the SSD-5K?+
Synchronics typically completes Ravel SmartServo drive repairs within 7-10 business days depending on parts availability and encoder recalibration complexity. For urgent textile mill production restarts, we can fast-track critical repairs within 48 hours. All servo drives undergo full burn-in testing and motion profile validation before return. We provide courier tracking throughout repair and send detailed test reports with every unit.
Can Synchronics recover a Ravel RC-32 PLC that won't power up after a factory electrical surge?+
Yes. Synchronics has recovered dozens of Ravel RC-series controllers damaged by electrical surges. We perform component-level diagnostics to identify burned input cards, damaged DC power regulators, and corrupted firmware. If your RC-32 won't boot, we extract the program from backup or your spare unit, replace damaged semiconductor modules, and reprogram the controller. We also install surge suppression modules to prevent recurrence and provide a detailed damage assessment report to support insurance claims.
What spares does Synchronics keep in stock for Ravel equipment?+
Synchronics maintains working inventory of Ravel replacement parts including input/output card modules for RC-series PLCs, encoder connector assemblies, DC bus capacitor banks for PowerLink inverters, LED backlight modules for HMI panels, CAN-bus transceiver chips, and brake control relays. We also hold firmware ROM chips and can reprogram field-programmable units to match your original configuration. Custom spares can be sourced from UK distributors within 5-7 days if not in stock.
Do you offer calibration and testing certificates for repaired Ravel servo drives?+
Yes. Every Ravel SmartServo and PowerLink inverter repaired by Synchronics is returned with factory-level calibration certificates documenting encoder alignment, servo response time, current sensing accuracy, and thermal stability. We test each unit under simulated production loads on our multi-axis test rig and provide motion profile validation reports. All certificates are ISO 9001 compliant and recognized by Indian textile and packaging industry quality auditors.
How do I send my Ravel 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 Ravel 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 Ravel 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 Ravel 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.
