RENU Equipment We Repair — By Category
RENU Product Lines We Repair
Our engineers are trained on the full RENU product range. Below are the major product families we service.
RENU VFD Series (3-Phase Industrial Drives)
Voltage range 1.5 kW to 400 kW. Common repairs include IGBT module failures, capacitor degradation, and firmware corruption. Used extensively in pump control, conveyor systems, and textile machinery applications across Indian plants.
RENU Soft Starter Series (Reduced Voltage Starters)
22A to 600A rated soft starters for motor inrush current management. Frequent issues include thyristor failures, control card faults, and thermal relay malfunctions affecting pump and compressor startups in cement and chemical industries.
RENU Servo Drive Module (Precision Motion Control)
Advanced closed-loop servo systems for packaging, printing, and textile machinery. Repair challenges include encoder interface failures, current sense amplifier drift, and position loop instability requiring precision oscilloscope diagnostics and parameter re-tuning.
RENU PLC and Logic Controller Series
Compact programmable logic controllers for process automation and machine control. Common faults include memory corruption, I/O module burnout, communication port failure, and Ethernet interface degradation affecting Indian SME manufacturing networks.
RENU Power Supply Modules (Industrial PSU)
Regulated 24V DC and 48V DC industrial power supplies ranging 50W to 1000W. Typical failures: capacitor swelling, transformer saturation, rectifier bridge failure, and output voltage regulation loss affecting critical control systems.
RENU Analog and Digital I/O Modules
Modular input/output cards for sensor integration and equipment control. Repair expertise includes optoisolator replacement, analog amplifier recalibration, and insulation resistance restoration for hazardous area installations.

Common RENU Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in RENU equipment arriving at our workshop.
- ✓RENU VFD IGBT Module Thermal Runaway Failure — Insufficient heatsink contact pressure, degraded thermal paste, or junction temperature sensor drift in RENU drives operating above 45C ambient in Indian textile mills. Water ingress accelerates this failure mode.
- ✓RENU Soft Starter Thyristor Misfire and Current Imbalance — Gate driver circuit failure, snubber capacitor degradation, or timing reference oscillator drift in RENU soft starters exposed to supply voltage fluctuations common in Indian industrial grids (±10% variations).
- ✓RENU PLC Memory Corruption and Program Loss — Inadequate backup battery voltage, flash memory cell failure, or electrical transient damage to RENU PLC during power disruptions or lightning strikes affecting Indian manufacturing facilities without proper surge protection.
- ✓RENU Encoder Interface and Position Feedback Dropout — Loose connector contacts, shielding degradation, or differential receiver IC failure in RENU servo drives caused by high-vibration textile or packaging machinery environments common in Indian factories.
- ✓RENU Capacitor Bank Swelling and Leakage Current Rise — Extended operation in hot, humid Indian manufacturing environments, coupled with high harmonic distortion from non-linear loads, causing electrolytic capacitor aging and internal pressure buildup in RENU power supplies and VFDs.
- ✓RENU Drive Firmware Version Mismatch and Control Loop Instability — Partially programmed firmware, corrupted bootloader, or parameter set incompatibility between RENU drive versions causing velocity oscillation and torque ripple in Indian cement kiln drives and conveyor systems.

Frequently Asked Questions — RENU Repairs
Do you repair RENU equipment anywhere in India?+
Yes. Synchronics repairs the complete RENU product portfolio — VFDs, soft starters, servo drives, PLCs, power supplies, and I/O modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Jaipur, and all tier-1/tier-2 cities. Equipment is serviced at our Vadodara facility and returned with full warranty.
Can you repair RENU VFDs that have burned-out IGBT modules?+
Absolutely. IGBT module failure is one of the most common RENU VFD repairs. Synchronics stocks replacement power modules for all RENU drive ratings (1.5 kW to 400 kW), installs with precision thermal paste and torque specifications, performs full electrical testing, and validates gate driver functionality before dispatch. Typical turnaround is 5-7 business days.
My RENU soft starter is showing unbalanced starting current across three phases. What could be wrong?+
Unbalanced three-phase starting in RENU soft starters typically indicates thyristor firing angle mismatch, gate driver timing drift, or snubber component failure. Synchronics measures phase angles using oscilloscope, replaces faulty thyristor modules and driver circuits, and validates phase balance within 2% before returning. This is a common issue in Indian grid environments with voltage asymmetry.
How long does RENU servo drive repair typically take?+
Servo drive repair complexity varies. Simple encoder connector repairs take 2-3 days. Position loop calibration and differential receiver replacement require 5-7 days. Full servo control board replacement and tuning may require 10 business days. Synchronics expedites critical repairs for textile and packaging machinery; most work completes within your scheduled maintenance window.
Do you have genuine RENU spare parts in stock?+
Yes. Synchronics maintains inventory of genuine RENU capacitors, thyristor modules, IGBT modules, control ICs, connectors, and firmware. For non-stock items, we source directly from authorized RENU distributors with 48-72 hour lead time across India. We never use counterfeit components; all repairs come with parts warranty and OEM compliance certification.
How do I send my RENU 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 RENU 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 RENU 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 RENU 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.
