DIMAC Equipment We Repair — By Category
DIMAC Product Lines We Repair
Our engineers are trained on the full DIMAC product range. Below are the major product families we service.
DIMAC Servo Drives (DC)
Precision DC servo drives used in textile looms, printing presses, and packaging machinery. Common failures include thyristor bridge failures, capacitor ripple breakdown, and control board firmware corruption under voltage spikes.
DIMAC AC Motor Controllers
Industrial AC drive units for spindle motors and conveyor systems. Susceptible to phase loss detection circuit failure, encoder interface faults, and thermal runaway due to inadequate cooling in high-dust environments.
DIMAC Embedded Motion Controllers
Programmable motion control boards for multi-axis applications. Typical faults include real-time clock drift, analog input conditioning circuit failure, and corrupted motion profile memory.
DIMAC Encoder Interface Modules
Specialized interface boards for incremental and absolute encoders in closed-loop servo systems. Failure modes include differential signal conditioning circuit degradation and quadrature decoding logic faults.
DIMAC Power Supply Units (PSU)
Regulated 24VDC and 48VDC supplies for drive and control circuits. Common issues: transformer insulation breakdown, bridge rectifier failure, and voltage regulation IC malfunction under load transients.
DIMAC Fieldbus Gateway Modules
Interface modules for PROFIBUS, CANopen, and analog I/O integration in networked automation cells. Faults typically involve protocol stack crashes, memory corruption, and transceiver IC failure.

Common DIMAC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DIMAC equipment arriving at our workshop.
- ✓Thyristor bridge gate drive circuit failure — DIMAC DC servo drives use phase-controlled thyristor bridges; gate drive transformers and optocoupler circuits degrade under sustained overload or electromagnetic interference from adjacent plant equipment. Gate signal loss results in uncontrolled commutation and motor cogging.
- ✓Encoder signal conditioning circuit noise immunity loss — DIMAC servo systems rely on precise encoder feedback; differential receiver circuits (often ECL or LVDS based) degrade when exposed to high dV/dt transients from switching power supplies or motor cable crosstalk. Signal-to-noise ratio drops below decode threshold.
- ✓Capacitor ripple voltage failure in main DC bus — DIMAC drives use aluminum electrolytic capacitors in harsh factory environments with temperature swings, dust ingress, and harmonic current from non-linear loads. Capacitor ESR increases, ESL broadens, and rated ripple current margin is exceeded leading to catastrophic failure.
- ✓Motion profile memory corruption and erratic axis movement — DIMAC embedded motion controllers store trajectory tables and velocity ramps in on-board EEPROM; electromagnetic interference during runtime or improper firmware update procedures corrupt the motion database. Axes execute partial or inverted profiles.
- ✓Analog-to-digital converter (ADC) channel accuracy loss and setpoint creep — DIMAC servo drive analog command inputs rely on precision ADC stages; capacitive coupling circuits and voltage reference buffers drift due to thermal stress, moisture ingress into PCB fiberglass, and aging of thin-film resistor networks. Loop gains require constant manual re-tuning.
- ✓PROFIBUS gateway protocol stack timeout and intermittent fieldbus loss — DIMAC fieldbus gateway modules run embedded real-time PROFIBUS or CANopen stacks; memory leaks in protocol handler routines, missing watchdog timer service calls, or congestion from high-frequency polling cause stack crashes. Equipment drops off network for 5-30 seconds at random intervals.

Frequently Asked Questions — DIMAC Repairs
Do you repair DIMAC equipment anywhere in India?+
Yes. Synchronics repairs the full DIMAC product range — servo drives, AC controllers, motion boards, encoder interfaces, power supplies, and fieldbus modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Indore, Surat, and all other cities. All repairs are handled in our central facility in Vadodara, Gujarat, with turnaround time of 5-10 working days for most faults.
What is a typical DIMAC servo drive fault and how do you diagnose it?+
Common DIMAC servo drive failures include thyristor gate drive loss, encoder signal noise, and capacitor ripple failure. Synchronics uses thermal imaging to detect failed power semiconductors, oscilloscope analysis to capture encoder waveforms and gate drive signals, and precision LCR metering to measure capacitor ESR and ripple current. We provide detailed fault reports with root cause analysis and preventive recommendations.
Can Synchronics reprogram or update DIMAC servo drive firmware?+
Yes. Synchronics has access to DIMAC firmware repositories and specialized programming equipment. We can update motion controller code, reprogram servo gain tables, restore corrupted EEPROM motion profiles, and modify soft-start parameters. All firmware updates are performed in a controlled test environment with load simulation before return to customer.
Our DIMAC textile loom drive keeps losing encoder feedback intermittently. What could be the cause?+
Intermittent encoder loss in DIMAC servo systems typically results from signal conditioning circuit noise immunity degradation, poor cable shielding, or connector corrosion. DIMAC drives are sensitive to high dV/dt transients from nearby switching supplies and motor PWM noise. Synchronics inspects encoder cabling for physical damage, measures differential signal amplitude using high-bandwidth oscilloscopes, tests receiver IC response to noise injection, and upgrades shielding and ferrite filtering if needed.
How much does a typical DIMAC servo drive repair cost in India?+
Repair costs depend on fault severity. Minor issues (firmware corruption, capacitor replacement, encoder interface reset) typically cost Rs. 8,000-15,000. Major failures (thyristor bridge replacement, multi-stage board redesign, encoder signal path restoration) range Rs. 25,000-50,000. Synchronics provides free diagnostic assessment via email or phone and detailed quote before proceeding. We also offer spare parts availability and warranty on repaired units.
How do I send my DIMAC 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 DIMAC 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 DIMAC 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 DIMAC 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.
