Expert DMA servo drive and motion controller repair across all generations and application types.
DMA Product Lines We Repair
Our engineers are trained on the full DMA product range. Below are the major product families we service.
DMA Servo Amplifiers
Compact single and multi-axis servo amplifiers with integrated motion control. Common failures include capacitor ripple failures (caused by Indian power quality), encoder connection loss due to vibration-induced wire breakage, and thermal shutdown caused by inadequate cooling in tropical climates.
DMA Stepper Drive Modules
Microstepping drivers for precision positioning in CNC, textile machinery, and packaging equipment. Typical faults include driver IC burnout from phase winding shorts, encoder loss-of-signal errors, and firmware corruption from power surges during monsoon season.
DMA Motion Controller Boards
Modular PLCs and motion controllers for multi-axis synchronized applications. Repair focus: relay contact welding in high-current switching circuits, EEPROM corruption, and CAN/Profibus communication interface failures.
DMA Encoder Interface Modules
High-resolution feedback systems for closed-loop motion. Frequent issues: incremental encoder signal loss from cable strain, commutation sensor offset errors, and SSI/CANopen communication dropouts in EMI-heavy factory floors.
DMA Power Supply Units
Regulated supplies for servo and stepper systems, typically 24V/48V DC outputs. Common failures: electrolytic capacitor degradation (high failure rate in Indian ambient temperatures), rectifier bridge shorts, and transformer core saturation under voltage fluctuations.

Common DMA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DMA equipment arriving at our workshop.
- ✓Servo amplifier thermal shutdown during monsoon — DMA servo drives in Indian coastal and humid regions experience accelerated electrolytic capacitor degradation. Combined with inadequate heatsink cooling due to dust accumulation, the amplifier enters thermal protection mode, causing intermittent axis lockouts.
- ✓Encoder signal loss - DMA E-code errors — Vibration-induced wire breakage in encoder cables, combined with poor shielding and grounding practices common in retrofit installations on older Indian machinery. DMA firmware reports E-code 42 (encoder timeout).
- ✓Power supply capacitor ripple failure — Indian industrial power supply contains 100-250V voltage spikes and phase imbalance, especially in rural manufacturing zones. DMA PSUs use standard aluminum electrolytic capacitors that fail prematurely under these conditions within 2-3 years.
- ✓CAN/Profibus communication timeout — EMI from nearby welding equipment, VFDs, or overhead power lines in integrated manufacturing halls causes communication packet loss on DMA MotionLogic controllers. Improper fieldbus grounding and unshielded cables exacerbate the issue.
- ✓EEPROM corruption - DMA parameter loss — Sudden power loss (common during load-shedding in Indian grids) during EEPROM write cycles corrupts servo parameters, acceleration profiles, and PID tuning values stored on DMA motion controllers.
- ✓Stepper driver IC burnout - phase short — Winding phase shorts in stepper motors connected to DMA Step-Pro drivers, often caused by mechanical jam or excessive load causing current surge that overwhelms the integrated H-bridge driver IC (typically Allegro or TI chipset).

Frequently Asked Questions — DMA Repairs
Do you repair DMA equipment anywhere in India?+
Yes. Synchronics repairs the full DMA product range across all generations - servo amplifiers, stepper drives, motion controllers, encoder interfaces, and power supplies. We offer PAN India door pickup service from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other major cities. All repairs are performed at our fully equipped facility in Vadodara, Gujarat, with TAT of 5-7 working days for most units.
What is DMA E-code 42 and how do you fix it?+
E-code 42 on DMA servo drives indicates encoder timeout - the amplifier has lost communication with the rotary encoder feedback signal. Root causes include cable breakage from vibration, connector corrosion, or encoder power supply failure. Synchronics diagnoses via oscilloscope signal verification, tests encoder output voltage (typically 5V square wave or 0-10V analog), repairs cabling with proper shielding, and replaces connectors as needed. We also check encoder mounting and alignment on the motor shaft.
How often should DMA servo capacitors be replaced preventively?+
In Indian industrial environments with high ambient temperature (35-45°C) and humidity, DMA servo amplifier electrolytic capacitors degrade faster than in European climates. We recommend capacitor replacement every 4-5 years of continuous operation, or earlier if you notice thermal shutdown events or ripple voltage above 500mV. Synchronics can perform preventive capacitor upgrades using high-reliability, extended-temperature rated alternatives during routine maintenance.
Does DMA drive firmware need updating for Indian power supply conditions?+
Yes. Standard DMA firmware assumes regulated 3-phase 50Hz supply with <5% voltage imbalance. Indian grids commonly see 10-15% imbalance, voltage spikes up to 250V, and phase dropouts in rural areas. Synchronics applies custom firmware patches to increase thermal protection margins, adjust encoder signal timing windows, and enable brownout recovery on DMA MotionLogic and servo drive units. We also advise on AVR or UPS backup installation at the machinery input.
Can Synchronics repair DMA stepper drivers with blown ICs?+
Yes, absolutely. DMA Step-Pro and MicroStep drivers commonly fail due to phase winding shorts or overcurrent events that burn out the integrated stepper driver IC. Synchronics replaces ICs (Allegro A4988, TI DRV8825, or equivalent) with OEM or high-reliability alternatives, tests motor winding resistance, reprograms micro-stepping profiles, and performs load testing. We recommend installing soft-start circuits and current limiting resistors to prevent future failures.
How do I send my DMA 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 DMA 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 DMA 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 DMA 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.
