DELTA Equipment We Repair — By Category
DELTA Product Lines We Repair
Our engineers are trained on the full DELTA product range. Below are the major product families we service.
DVP PLC Series
DELTA's modular programmable logic controllers (DVP-EH, DVP-ES, DVP-SX) used for machinery control, sequencing, and process automation. Common issues include corrupt program memory, communication module failures, and relay output failures.
DOP HMI Touch Panels
DELTA's operator interface terminals (DOP-B, DOP-W, DOP-AS) for real-time monitoring and machine control. Repair needs typically include LCD screen corruption, touchscreen calibration failure, communication card defects, and firmware corruption.
VFD Variable Frequency Drives
DELTA's variable frequency drives (VFD-M, VFD-B, VFD-EL) for motor speed control in pumps, fans, and conveyors. Common failures include power stage IGBT breakdown, capacitor bank degradation, and cooling fan motor failures.
ASDA-A2 Servo Drive System
DELTA's closed-loop servo drive and motor platform for precision positioning in textile machinery, printing presses, and packaging lines. Typical repair issues include servo encoder communication loss, power module thermal shutdown, and brake solenoid failures.

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 DELTA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DELTA equipment arriving at our workshop.
- ✓DVP PLC program memory corruption or loss — Power fluctuations, defective backup battery, or corrupted SD card in communication modules cause the DVP series to lose stored logic programs. This is particularly common in Indian facilities with unstable grid power.
- ✓DOP HMI touchscreen unresponsive or calibration drift — Environmental humidity, temperature extremes, and dust ingress damage the capacitive touch sensor layer in DOP panels. Indian manufacturing facilities with poor climate control experience accelerated touchscreen degradation.
- ✓VFD overheating and thermal shutdown (Er7/Er8 codes) — Cooling fan motor failure, blocked heatsink fins, or defective thermal sensor in VFD power stage. High ambient temperatures in Indian summer and poor ventilation in cramped machinery rooms accelerate thermal failures.
- ✓ASDA servo drive encoder communication loss (Er24 fault) — Loose or damaged encoder cable connections, shielding deterioration, or encoder signal converter card failure in the servo drive module. Vibration from running machinery degrades encoder connectors over time.
- ✓DVP communication module Ethernet or RS232 port failure — Static discharge, lightning surge, or prolonged power transient damage the network interface circuitry in DELTA communication expansion cards. Indian facilities without adequate surge protection are particularly vulnerable.
- ✓VFD inverter IGBT power stage failure (Er1/Er2 codes) — Thermal cycling, moisture ingress, or solder joint fatigue in IGBT modules causes short-circuit across the DC bus. Overloaded motor conditions or locked rotor faults accelerate power stage wear.

Frequently Asked Questions — DELTA Repairs
Do you repair DELTA equipment anywhere in India?+
Yes. Synchronics repairs the full DELTA product range — DVP PLCs, DOP HMI panels, VFD drives, servo systems, and communication modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all tier-2 industrial cities. Equipment is transported to our central repair facility in Vadodara, Gujarat, and returned with comprehensive test reports.
What is the typical turnaround time for DELTA PLC or HMI repair?+
Standard DELTA repairs (DVP PLC, DOP HMI) are completed in 3-5 working days from receipt. Inverter and servo drive repairs typically take 5-7 days due to thermal stress testing and motor load verification. Express service is available for critical production equipment — we can prioritize your DELTA unit for 1-2 day turnaround. All repairs come with 90-day warranty and detailed technical report.
Can you repair DELTA VFD drives with burnt power modules?+
Yes. Synchronics specializes in VFD power stage repair and replacement. We stock genuine DELTA IGBT modules, capacitor banks, and thermal management components. If your VFD shows Er1, Er2, or thermal shutdown codes, we diagnose the failure, replace burnt components, and perform DC bus voltage testing and motor load simulation before return. We also identify why the power stage failed — often motor winding issues or mechanical jamming — and advise preventive measures.
What DELTA servo drive models do you repair, and how long is the turnaround?+
Synchronics repairs the entire ASDA-A2 servo drive family (ASDA-A2-BE, ASDA-A2-E, ASDA-A2-EU variants). Common servo issues — encoder communication loss, brake solenoid failure, thermal sensor faults, and servo encoder alignment problems — are repaired and tested on our servo load bench. Typical turnaround is 5-7 days. We verify servo response across full speed range before return to ensure textile machinery, printing presses, and packaging lines restart without positioning errors.
Do you source genuine DELTA replacement parts and components?+
Yes. Synchronics maintains stock of genuine DELTA spare parts — EEPROM modules, cooling fans, capacitor banks, IGBT power modules, touchscreen panels, encoder cables, and communication cards. We never use counterfeit or substandard components. All parts are sourced through authorized DELTA distributors in India. Genuine parts carry manufacturer warranty and ensure your DELTA equipment meets original performance specifications and safety standards.
How do I send my DELTA 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 DELTA 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 DELTA 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 DELTA 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.
