ASD-B Series Servo Drives
High-precision servo amplifiers for closed-loop motion control in packaging, textile, and precision manufacturing. Repair focus on Hall sensor interface failures, encoder communication loss, and thermal shutdown issues.
DVP Series Programmable Logic Controllers
Compact PLC modules for discrete automation and process control. Frequently repaired for input/output card failures, power supply degradation, and program memory corruption affecting industrial relay and counter functions.
AS Series Motion Controllers
Advanced multi-axis motion control systems for CNC machines, printing equipment, and automated assembly lines. Common issues include axis calibration loss, interpolation errors, and communication interface faults with stepper and servo motors.
DOP Series Human-Machine Interfaces
Industrial touchscreen and panel displays for operator control and real-time monitoring. Repair addresses LCD backlight failure, touch sensor degradation, communication port failures, and corrupted firmware leading to display freeze or unresponsive input.
ASD-A Series Frequency Inverters
Advanced industrial inverters for medium-voltage three-phase motors in steel mills, textile processing, and heavy manufacturing. Specialist repair for power module IGBT faults, gate driver failures, and cooling system malfunctions.

Common DELTA ENGINEERING Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DELTA ENGINEERING equipment arriving at our workshop.
- ✓VFD capacitor bank failure causing nuisance tripping — Delta VFD electrolytic capacitors in the DC bus degrade over 5-8 years due to high ambient temperatures (40-50°C common in Indian plants) and continuous industrial duty cycles. This increases internal ESR, reducing filtering efficiency and triggering overvoltage protection shutdowns.
- ✓Servo drive encoder communication loss (Error E16) — Delta ASD-B servo amplifiers lose connection to motor encoder due to cable shielding degradation, bent connector pins, or loose ferrite clamp near motor leads. Common in high-vibration environments like spinning frames and pressing machines.
- ✓VFD fault code F0001 (overload detected) — Delta drives record false overload trips due to software watchdog timeout, shorted IGBTs in power stage, or calibration drift in current measurement circuitry after 6+ years of thermal cycling in foundries and chemical plants.
- ✓DVP PLC input/output card malfunction (channels reading stuck or inverted) — Delta compact PLCs suffer I/O card failures when exposed to electrical transients, surge current spikes from solenoid switching, or contamination ingress in humid environments common to food processing and textile mills across Gujarat and Tamil Nadu.
- ✓DOP HMI touchscreen unresponsive or display flicker — Delta industrial panels experience LCD backlight LED failure, loose LVDS ribbon connectors inside the panel, or touch controller IC degradation after 3-4 years in high-humidity environments like textile sizing and paint shops. Vibration also causes ribbon cable micro-fractures.
- ✓Stepper motor controller stall or axis position loss (AS series) — Delta motion controllers lose axis reference during CNC printing or automatic packaging operations due to stepper phase winding shorts, step pulse signal noise on shared control cables, or firmware corruption from power supply transients.

Frequently Asked Questions — DELTA ENGINEERING Repairs
Do you repair DELTA ENGINEERING equipment anywhere in India?+
Yes. Synchronics repairs the full Delta Engineering product range — VFD drives, servo amplifiers, PLCs, motion controllers, HMIs, and stepper systems. We offer PAN India door pickup from major metros: Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all regional cities. Same-facility diagnostics and repair at our Vadodara, Gujarat headquarters.
What is the typical turnaround time for Delta VFD and servo drive repair?+
Standard turnaround is 5-7 working days for diagnostics, spare part procurement, repair, and full functional testing. Express 48-72 hour service available for critical production equipment. Synchronics maintains stock of common Delta capacitors, IGBT modules, relay cards, and encoder components to minimize wait time. Urgent cases receive priority bench allocation.
Do you stock genuine Delta Engineering spare parts and components?+
Yes. Synchronics maintains authorized inventory of Delta spare parts including capacitor modules, IGBT power stages, optoisolator I/O cards, LCD display panels for DOP series, and servo motor feedback cables. We source directly from Delta Electronics and authorized distributors to guarantee authenticity. All spares come with warranty and fit verification before installation.
Can you repair Delta VFD fault codes like F0001, F0003, and E16?+
Yes. We specialize in Delta fault code diagnosis and repair across all VFD-M, ASD-A, and ASD-B series. Fault codes F0001 (overload), F0003 (overvoltage), and E16 (encoder loss) require different root-cause analysis. Our engineers use Delta diagnostic software and oscilloscopes to pinpoint hardware vs. software issues, perform component-level repair, and validate fault resolution before customer dispatch.
Do you offer on-site support or preventive maintenance for Delta automation systems?+
Yes. Synchronics provides field service contracts, on-site diagnostics, and predictive maintenance programs for Delta equipment in Indian plants. We conduct thermal imaging of VFD heatsinks, vibration analysis of servo-driven shafts, and capacitor ESR trending to predict failures 2-3 months in advance. Preventive service reduces unplanned downtime and extends equipment life by 3-5 years.
How do I send my DELTA ENGINEERING 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 ENGINEERING 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 ENGINEERING 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 ENGINEERING 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.
