30+ years repairing IDI drives and automation controllers across Indian manufacturing.
IDI Product Lines We Repair
Our engineers are trained on the full IDI product range. Below are the major product families we service.
IDI Variable Frequency Drives (VFD)
IDI's compact AC drives for motors 0.75 kW to 37 kW, widely deployed in Indian textile spindles and sugar processing equipment. Common issues include firmware corruption, IGBT thermal failures, and control board capacitor degradation under high ambient temperatures.
IDI Programmable Logic Controllers (PLC)
Modular PLC systems used for sequencing in packaging lines, pump control, and process automation across Indian food and pharma industries. Typical faults include input/output card failures, battery backup depletion, and communication module dropout.
IDI Soft Starter / Motor Control Modules
Electronic soft-start controllers reducing mechanical shock on mill motors and conveyor systems. Prone to phase-control thyristor aging, signal conditioning circuit failures, and protection relay calibration drift in tropical climates.
IDI HMI Touch Panels
7-inch to 15-inch industrial touchscreen interfaces for factory floor operator control stations. Screen flickering, touch input non-responsiveness, and Ethernet port intermittency are common field failures requiring reprogramming or display replacement.
IDI Communication Modules (Profibus, Ethernet, CANopen)
Gateway and communication interface cards enabling IDI equipment to integrate with Siemens SCADA systems and factory networks across Indian sugar mills and pharmaceutical plants. Dropout, protocol stack errors, and isolation failure are typical faults.
IDI Power Supply Units (PSU)
24 VDC switching power supplies embedded in IDI control cabinets and remote I/O racks. Common failures include blown rectifier bridges, transformer saturation from voltage spikes, and electrolytic capacitor dry-out in high-temperature mill environments.

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 IDI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in IDI equipment arriving at our workshop.
- ✓IDI VFD displays 'PH' or 'OC' fault code — Phase loss on motor supply or over-current detection due to winding short-circuit, cable damage, or IGBT bridge failure inside the drive. Common in Indian textile mills where single-phase supply fluctuations are frequent.
- ✓IDI PLC loses program after power cycle or shows 'BAT' warning — Backup battery (Lithium coin cell) inside CPU module has depleted, allowing program memory to corrupt. Typical in equipment running 15+ years or in environments with frequent power cuts across rural Indian factories.
- ✓IDI Soft Starter shows 'TH' (thermal) alarm constantly or fails to energise motor — Thyristor gate-drive circuit failure, phase-control optoisolator degradation, or snubber capacitor open-circuit. Exacerbated in high-ambient sugar factory and textile dyeing environments common across India.
- ✓IDI HMI touchscreen shows ghosting, dead zones, or partial screen blackout — LCD panel degradation from humid factory environment, digitiser calibration loss, or video buffer memory error. Indian coastal and monsoon-prone regions see accelerated display aging.
- ✓IDI Communication Module loses Profibus or Ethernet link intermittently — Isolation optocoupler failure on RS-485/Profibus interface, loose connector contact due to vibration, or firmware communication stack timeout. Particularly common in vibrating machinery and foundry environments.
- ✓IDI Power Supply Unit outputs zero or unstable 24 VDC; control circuits dead — Blown input rectifier diode or bridge due to mains surge, transformer short-circuit from moisture ingress, or regulator IC thermal shutdown. Common post-monsoon failure in Indian mill control cabinets with poor cabinet sealing.

Frequently Asked Questions — IDI Repairs
Do you repair IDI equipment anywhere in India?+
Yes. Synchronics repairs the full IDI product range — variable frequency drives, PLCs, soft starters, HMI panels, and communication modules. We offer pan-India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other major cities. All repairs are performed at our Vadodara, Gujarat facility with 30-day turnaround on most faults.
What is an IDI 'PH' fault code on a VFD, and can you repair it?+
PH indicates phase loss or phase rotation error. It occurs when one of three mains supply phases is missing or reversed — common in Indian mills with weak grid connections. Synchronics diagnoses the root cause (motor winding short, cable damage, or IGBT failure), performs insulation testing, and replaces faulty power modules. We calibrate the protection relay and test under full load before return.
My IDI PLC lost its program after a power cut. Can Synchronics recover it?+
Yes. If you have a backup program file, we restore it immediately. If not, Synchronics may be able to extract the program from the EEPROM memory chip using specialised tools (success depends on memory integrity). We also replace the backup battery, update to the latest firmware, and recommend implementing UPS or dedicated 24 VDC backup supplies to prevent future data loss.
How much does IDI drive or PLC repair cost, and do you offer warranty?+
Repair costs depend on the fault type and parts required (typically INR 2,500 to 15,000 for drive repairs). Synchronics offers a 12-month warranty on all repairs, covering parts and labour. We provide free fault diagnosis, detailed quotation, and rapid turnaround for critical production equipment. Onsite repairs and commissioning support are available at additional cost.
Does Synchronics stock spare parts for IDI drives and PLCs?+
Yes. Synchronics maintains stock of common IDI spare components — IGBT modules, capacitors, optoisolators, communication cards, and touchscreen panels. We source genuine replacements and equivalent alternatives approved by IDI. Custom module programming and parameter configuration are included in our repair service.
How do I send my IDI 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 IDI 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 IDI 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 IDI 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.
