DELFI-TECH Product Lines We Repair
Our engineers are trained on the full DELFI-TECH product range. Below are the major product families we service.
DFS-Motion Servo Drive Family
High-performance brushless servo drive controllers with integrated encoder feedback and multi-axis synchronisation. Common issues: encoder cable faults, phase loss detection errors, brushless commutation signal dropout, thermal sensor failures, and firmware version incompatibility with legacy motion software.
DELFI Stepper Control Modules
Compact stepper motor driver boards for precision positioning in packaging and labelling machinery. Prone to coil winding breakdown from moisture ingress, microstepping circuit failures, and power supply capacitor aging in high-temperature factory environments.
DRT-RealTime Controller Platform
Embedded real-time control processor for synchronous multi-axis motion and I/O handling. Failure modes include FPGA bitstream corruption, DRAM module defects, SD card filesystem errors, and RTC battery depletion affecting scheduled motion profiles.
DELFI HMI Touch Panel Series
Industrial touch interfaces for DELFI-TECH motion systems, featuring 7-inch and 10-inch displays. Common repairs include LCD panel backlight failure, capacitive touch controller IC defects, Ethernet port corrosion, and SD card slot damage from repeated firmware updates.
DFS-IO Fieldbus Gateway Modules
PROFIBUS, EtherCAT, and MODBUS interface modules for DELFI servo drives. Issues include isolated DC-DC converter failures, optocoupler circuit degradation, firmware synchronisation loss, and connector pin corrosion in dusty mill environments.
DELFI Power Supply Units (PSU)
Stabilised 24V, 48V industrial power supplies with redundancy and overvoltage protection for DELFI-TECH control systems. Typical failures: capacitor bulging, transformer thermal breakdown, voltage regulation IC failure, and fuse holder corrosion from industrial contaminants.

Common DELFI-TECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DELFI-TECH equipment arriving at our workshop.
- ✓DFS servo drive encoder signal loss and phase error — DELFI servo drives rely on incremental or absolute encoders for commutation feedback. Encoder cable abrasion, connector corrosion from humidity, or encoder IC sensor chip failure causes the DFS to report ERR-ENC-001 or ERR-COMM-302, disabling the servo loop and halting synchronized motion.
- ✓DRT real-time controller FPGA bitstream corruption — Power supply fluctuations during firmware updates, SD card read errors, or extended storage in high-temperature environments cause FPGA configuration memory corruption. The DRT-X series displays ERR-FPGA-CONF-FAIL and locks motion control, requiring factory bitstream re-upload.
- ✓DSM stepper driver coil winding short circuit — In humid Indian textile and packaging mills, moisture penetrates the DSM stepper module windings, causing phase-to-phase short circuits. The driver IC thermal sensor detects the current spike and cuts power, reported as ERR-COIL-SHORT or ERR-THERM-CUTOUT, stopping intermittent position movements.
- ✓DFS-IO fieldbus gateway Ethernet port failure — EtherCAT or industrial MODBUS Ethernet modules in DELFI-IO gateway cards suffer from pin corrosion, isolation transformer saturation, and connector pin pitting due to high dust and electrical transients common in Indian automotive and packaging plants. Interface shows ERR-LINK-DOWN or intermittent packet loss.
- ✓DHM HMI touch panel LCD backlight and capacitive touch failure — DELFI-TECH DHM touch panels in harsh factory environments experience backlight CCFL or LED aging, electrochemical migration in the touch controller capacitive matrix, and power supply IC failure. Panel becomes unresponsive or displays dim, flickering image with ERR-TOUCH or ERR-LCD codes.
- ✓DPS power supply electrolytic capacitor bulging and voltage instability — DELFI PSU capacitors deteriorate in Indian factories operating 24/7 in 45-50 degree Celsius ambient temperatures. Capacitor ESR increases, reducing ripple rejection and causing servo drive supply voltage sag, triggering ERR-PSU-LOW-VOLTAGE and jerky motion or position loss.

Frequently Asked Questions — DELFI-TECH Repairs
Do you repair DELFI-TECH equipment anywhere in India?+
Yes. Synchronics repairs the full DELFI-TECH product range — servo drives, stepper controllers, real-time processors, HMI touch panels, fieldbus gateways, and power supplies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bengaluru, Kolkata, and all other cities. Same diagnostic and repair facility in Vadodara, Gujarat. Express turnaround available for critical production equipment.
My DELFI DFS servo drive shows ERR-COMM-302. Can you fix it?+
ERR-COMM-302 is a commutation signal loss error, usually caused by encoder connector corrosion or encoder IC failure. Synchronics diagnoses the root cause using encoder signal oscilloscope analysis, cable resistance measurement, and IC functionality testing. We replace faulty components, recalibrate encoder offset for your machinery's mechanical setup, and test the servo loop under load before return. Most recoveries complete within 3-5 working days.
What happens if my DRT-RealTime controller suffers FPGA corruption during a firmware update?+
FPGA bitstream corruption locks your motion control system. Synchronics has direct access to DELFI-TECH's factory programming tools and official bitstream files. We restore the correct firmware, perform complete system validation including SD card integrity checks and power supply stability tests, and provide firmware backup procedures to prevent recurrence. This critical repair typically takes 1-2 days.
Can Synchronics repair DELFI stepper drivers damaged by moisture and humidity?+
Yes. Indian textile mills and packaging plants face severe moisture challenges. DELFI DSM stepper modules suffer coil winding short circuits from humidity. Synchronics replaces damaged coils, applies protective conformal coating, advises installation of enclosure desiccant packs, and tests motor holding torque and microstepping accuracy before shipment. We've successfully recovered dozens of DSM modules from high-humidity factory environments.
Do you carry DELFI-TECH spare parts inventory in India?+
Synchronics maintains critical DELFI-TECH spare parts inventory in Vadodara including encoder modules, stepper coils, power supply capacitors, fieldbus gateway cards, and touch panel LCD assemblies. For long-lead items, we coordinate directly with DELFI-TECH's European distribution network to minimise your downtime. Most routine repairs use in-stock components; larger projects are expedited via air freight.
How do I send my DELFI-TECH 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 DELFI-TECH 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 DELFI-TECH 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 DELFI-TECH 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.
