DYNAMICS RESEARCH Product Lines We Repair
Our engineers are trained on the full DYNAMICS RESEARCH product range. Below are the major product families we service.
DASHER and NOVA Real-Time Controllers
Ruggedized real-time computer systems for process control, data acquisition, and industrial automation. Common issues include memory module failures, backplane corrosion, power supply degradation, and firmware boot failures due to aging NVRAM or hard disk drive wear.
D-Series Motion Control Drives
Servo and stepper motor drive systems for precision positioning and motion applications. Frequent faults include thyristor/IGBT failures from thermal cycling, analog feedback signal loss, encoder interface degradation, and velocity loop instability causing oscillation.
I/O Expansion Modules and Interface Cards
Digital and analog input/output modules, communication interface cards (RS-232, RS-485, Ethernet adapters). Repair challenges include relay contact wear, optocoupler aging, connector corrosion, and signal conditioning circuit drift in analog modules.
Power Supply Units and Distribution Modules
Multi-rail power supplies and distribution boards for DRC systems. Typical failures: capacitor electrolyte leakage, rectifier bridge breakdown, transformer core saturation, voltage regulation circuit failure, and thermal shutdown due to fan bearing wear.
Legacy Firmware and EPROM Modules
Read-only memory modules, EPROM cartridges, and firmware storage devices. Common issues include data corruption, EPROM programming failures, firmware version incompatibility, and boot sequence failures from memory cell degradation.
Communication and Fieldbus Adapters
Industrial network interface boards supporting proprietary DRC protocols and standard fieldbus (Modbus, Profibus). Failures include transceiver chip damage, signal isolation transformer breakdown, and protocol stack firmware crashes.

Common DYNAMICS RESEARCH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNAMICS RESEARCH equipment arriving at our workshop.
- ✓Memory module failure and data corruption — Dynamics Research DASHER and NOVA systems use DRAM and NVRAM modules prone to electrolyte leakage in aging capacitors, resulting in intermittent memory access errors, checksums failures, and system lockups. Thermal cycling in Indian manufacturing environments accelerates degradation.
- ✓Power supply output voltage regulation failure — DRC multi-rail power supplies suffer from voltage reference circuit drift, failing pass-through transistors, and worn electrolytic capacitors causing output ripple. Under-voltage lockout trips or over-voltage damage to downstream logic boards result.
- ✓Servo drive thyristor and gate drive circuit failure — Dynamics Research D-Series servo drives experience thyristor or IGBT junction failures from gate drive circuit faults, leading to inability to energize motor windings. Thermal cycling and transformer losses in humid Indian plants accelerate failure.
- ✓Encoder feedback signal loss and velocity loop instability — Motion control systems lose quadrature encoder signals due to corroded connectors, broken signal cables, or encoder interface IC failure. This causes velocity loop oscillation and uncontrolled motor acceleration, risking equipment damage.
- ✓Communication interface board transceiver failure — RS-232/RS-485 transceiver chips in Dynamics Research communication cards degrade from ESD damage, over-voltage events, or long-term signal line stress. Serial communication becomes unreliable or ceases entirely.
- ✓EPROM and firmware programming failure — Legacy DRC systems using EPROM cartridges experience programming failures when cartridge contacts corrode, programmer equipment ages, or firmware images become corrupted. System fails to boot or runs incorrect application code.

Frequently Asked Questions — DYNAMICS RESEARCH Repairs
Do you repair Dynamics Research equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full Dynamics Research product range — DASHER and NOVA controllers, D-Series motion drives, I/O modules, power supplies, and communication adapters. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other major cities. All repairs are performed in our fully equipped facility in Vadodara, Gujarat. Typical TAT is 5-10 working days depending on fault complexity.
Can you repair legacy Dynamics Research DASHER systems no longer supported by the manufacturer?+
Absolutely. Many Indian plants still operate DASHER-32 and DASHER-48 controllers from the 1980s and 1990s. Synchronics has extensive experience diagnosing and repairing end-of-life DRC systems. We maintain spare memory modules, power supplies, and interface cards sourced from our inventory and carefully selected donors. Our engineers can also adapt DASHER-based systems with modern I/O interfaces or firmware updates if required.
What is included in a Dynamics Research servo drive repair?+
Our D-Series servo drive repair includes full diagnostic testing, thyristor/IGBT replacement if failed, gate drive circuit repair, power transformer inspection and winding testing, capacitor bank replacement with rated industrial components, velocity loop calibration, and load testing with dummy motor loads. We provide a detailed report with before/after performance curves and issue root-cause analysis.
How do you handle Dynamics Research firmware and EPROM cartridge issues?+
Synchronics uses advanced EPROM programming equipment and maintains an archive of legacy DRC firmware versions. If a cartridge cannot be reprogrammed due to cell degradation, we can often migrate to modern flash memory modules with firmware adaptation. We verify all firmware after programming using checksum validation and boot sequence testing on actual DRC hardware before shipment.
Do you offer on-site repair or support for Dynamics Research systems in Indian factories?+
Our primary service model is depot repair with free PAN India pickup and delivery. For urgent situations, we can arrange emergency on-site diagnostics or temporary system bypassing (subject to availability). Contact our technical support team in Vadodara with your site requirements and we will propose the best option for your production timeline and budget.
How do I send my DYNAMICS RESEARCH 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 DYNAMICS RESEARCH 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 DYNAMICS RESEARCH 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 DYNAMICS RESEARCH 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.
