DTI Product Lines We Repair
Our engineers are trained on the full DTI product range. Below are the major product families we service.
DTI Stepper Motor Drivers
Microstepping drivers for NEMA and industrial stepper motors, featuring variable current control and step/direction interfaces. Common issues include phase winding faults, current regulation drift, and thermal shutdown cycling in high-ambient manufacturing environments.
DTI Servo Amplifiers
Closed-loop servo drives with analog and digital command inputs, integrated velocity feedback loops, and multi-axis synchronization capability. Repairs address encoder signal loss, current loop instability, and commutation faults in high-speed spindle and positioning applications.
DTI Motion Controllers
Multi-axis motion control processors with real-time trajectory generation, networked command interfaces, and I/O expansion modules. Typical faults include timing synchronization errors, communication timeouts, and firmware corruption affecting coordinated axis movement.
DTI Encoder Interface Modules
Quadrature and SSI encoder signal conditioning cards with differential input protection and isolated digital outputs. Common failures include transformer burnout from power surges, high-speed pulse counting errors, and loss of encoder offset calibration.
DTI Power Supply Modules
Isolated DC supplies for multi-axis motor drive systems, featuring active current limiting and thermal protection circuits. Repair issues stem from capacitor aging, rectifier bridge faults, and regulation losses under full-load thermal stress.
Why Choose Synchronics for DTI Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on DTI equipment.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
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 DTI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DTI equipment arriving at our workshop.
- ✓Phase winding open circuit in stepper drivers — DTI stepper driver phase windings fail due to thermal cycling and inadequate heat dissipation in dusty Indian manufacturing plants. Extended continuous operation at rated current without thermal management accelerates insulation breakdown.
- ✓Servo encoder signal timeout error — DTI servo amplifiers expect continuous quadrature or SSI encoder pulses; loose connectors, EMI from adjacent welding equipment, or degraded cable insulation interrupts signal transmission and triggers fault shutdown.
- ✓Current regulation loop instability leading to motor chatter — DTI servo drive tuning parameters drift with component aging, or sampling frequency conflicts occur when multiple drives run on shared power distribution in industrial facilities. Inadequate DC bus capacitance amplifies the problem.
- ✓Thermal shutdown cycling under sustained load — DTI motor drivers accumulate dust on heatsink fins, or thermal sensor calibration drifts causing false over-temperature detection. Indian ambient temperatures exceeding 50°C in non-air-conditioned factories compound the issue.
- ✓Firmware corruption blocking motion controller startup — Power interruptions during DTI motion controller firmware updates, or bit flips in flash memory caused by static discharge in dry climates common during Indian summers corrupt the boot sector.
- ✓Multi-axis timing synchronization loss during high-speed coordinated motion — DTI controllers synchronize axes via shared timing references; EMI from spindle drives or inadequate real-time OS performance degrades inter-processor communication and causes axis drift during concurrent motion paths.

Frequently Asked Questions — DTI Repairs
Do you repair DTI equipment anywhere in India?+
Yes. Synchronics repairs the full DTI product range — stepper and servo drivers, motion controllers, encoder modules, and power supplies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Bangalore, and all other cities. All equipment is serviced at our facility in Vadodara, Gujarat, with 3-7 day turnaround on most repairs.
What is the typical repair cost for a DTI servo amplifier?+
DTI servo amplifier repairs typically cost INR 8,000-18,000 depending on fault severity. Minor issues like connector rework or thermal calibration cost INR 8,000-10,000. Component replacements (MOSFET stages, capacitor banks) range INR 12,000-18,000. We provide free diagnostic quotes and detailed repair reports after testing at Synchronics.
Can Synchronics repair DTI stepper drivers with burned-out phase coils?+
Yes, completely. If a DTI stepper driver phase winding is open or shorted, Synchronics re-winds or replaces the entire stator assembly. For models like SI-8718 and SI-8945, we maintain rebuilt coil stocks and test rewound units under full-current load. Repaired drivers receive updated heatsink designs and conformal coating for enhanced reliability in industrial environments.
How do I troubleshoot a DTI motion controller that won't boot after a power failure?+
First, verify power supply output voltages (typically 24V logic and 48V motor rails). Check that the DC link capacitor shows no visible damage or corrosion. If the controller LED does not illuminate, it may have corrupted firmware. Bring the unit to Synchronics for memory diagnostics — we can usually re-flash the boot sector and restore operation. UPS backup systems are recommended for facilities with unstable power to prevent future corruption.
Do you have DTI replacement parts in stock?+
Synchronics maintains a working inventory of common DTI components including stepper coils (NEMA 17, 23, 34 specifications), servo driver power MOSFETs, thermal sensors, and encoder interface ICs. For rare or obsolete DTI models, we source parts from global distributors with 5-10 day lead times. Emergency repairs can sometimes proceed with functionally equivalent substitutes approved by our engineering team.
How do I send my DTI 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 DTI 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 DTI 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 DTI 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.
