ADL Equipment We Repair — By Category
ADL Product Lines We Repair
Our engineers are trained on the full ADL product range. Below are the major product families we service.
ADL Servo Drives (SD Series)
Compact servo drive units controlling brushless and brush DC motors. Common issues include encoder communication loss, thermal shutdown under sustained load, and capacitor bank degradation affecting regenerative braking performance.
ADL Motion Controllers (MC Series)
Multi-axis motion control boards interfacing stepper and servo motors via step/direction or CAN protocols. Typical faults: step pulse generation failures, axis synchronisation loss, and memory corruption in stored motion profiles.
ADL Indexer Modules (IDX Series)
Dedicated indexing controllers for rotary and linear positioning in production machinery. Common problems: limit switch input failures, out-of-sync positioning after power interruption, and spindle speed regulation drift.
ADL Encoder Interface Boards (EIB Series)
Precision encoder signal conditioning and velocity feedback modules. Frequent issues include differential signal noise immunity loss, quadrature decoding errors, and hall commutation timing misalignment.
ADL Logic I/O Modules (LIO Series)
Isolated digital and analogue I/O expansion for machinery automation. Typical failures: relay coil burnout, opto-isolator LED degradation, and analogue signal conversion errors in harsh plant environments.

Common ADL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ADL equipment arriving at our workshop.
- ✓Encoder communication loss / quadrature signal error — ADL servo drives depend on continuous encoder feedback. Cable shielding breakdown, connector corrosion, or failed differential line drivers cause position sensing failure and motor stall.
- ✓Capacitor bank failure / regenerative braking shutdown — ADL servo drives use large electrolytic capacitor banks for energy storage during deceleration. Thermal cycling and plant humidity cause capacitor ESR rise and rupture, preventing energy discharge and triggering thermal alarms.
- ✓Step pulse generation failure / axis lockup — ADL motion controllers generate precise step/direction pulses for stepper motor control. Corrupted firmware, latch-up of output stage, or ground plane discontinuity causes missing or jittered pulses, leading to lost steps and mechanical stall.
- ✓PID loop instability / oscillatory motor behaviour — ADL servo drive tuning depends on proportional, integral, and derivative gain parameters. Plant parameter shifts or incorrect tuning causes underdamped oscillation, overshoot, or loss of convergence in velocity control.
- ✓Thermal shutdown during sustained high-load operation — ADL servo drives have built-in thermal protection. Heatsink dust accumulation, aged thermal interface material, or failed cooling fan reduces heat dissipation. Continuous current above rated torque triggers premature thermal trip.
- ✓Memory corruption / loss of stored motion profiles — ADL indexer and motion controller modules store programmed motion sequences in EEPROM. Power supply surges, static discharge, or failed write protection logic corrupt motion data, causing unexpected machine behaviour or refusal to start programs.

Frequently Asked Questions — ADL Repairs
Do you repair ADL equipment anywhere in India?+
Yes, Synchronics repairs the complete ADL product portfolio—servo drives, motion controllers, indexers, encoder interface boards, and I/O modules. We offer PAN India door pickup from Bangalore, Pune, Mumbai, Delhi, Chennai, Hyderabad, Ahmedabad, and all major industrial cities. All repairs are processed at our Vadodara, Gujarat facility with 48–72 hour turnaround for standard faults.
What is ADL encoder feedback and why does it fail in Indian manufacturing plants?+
ADL servo drives use rotary or linear encoders to sense motor position and speed in real-time. In India's high-heat, high-humidity, and dusty plant environments, encoder cable shielding degrades, connectors oxidise, and differential signal quality deteriorates. Synchronics replaces connector contacts, shields cables with shielded twisted pair, and tests quadrature signals before reinstalling drives on your machines.
How do I know if my ADL drive capacitor bank has failed?+
Typical signs: motor loses power suddenly during peak torque demand, drive triggers thermal protection without overload, or regenerative braking is disabled. If your ADL servo drive is 5+ years old and operates in a hot machine enclosure, capacitor ageing is likely. Synchronics performs ESR (equivalent series resistance) testing and replaces failed capacitor banks with high-reliability industrial components rated for Indian temperature extremes.
Can you reprogram ADL motion controller firmware and tune servo parameters?+
Absolutely. Synchronics has ADL development software and tuning tools. We reprogram corrupted EEPROM, restore factory firmware, rerun closed-loop servo tuning for your specific load, and save corrected PID gains. We test all axis movements and interpolation modes before dispatch. Typical cost and lead time depend on complexity; contact our engineers with your specific ADL model.
Do you stock ADL spare components and modules?+
Yes. Synchronics maintains inventory of high-wear ADL parts: electrolytic capacitors, differential line driver ICs, relay modules, thermal sensors, and opto-isolators. For older ADL models no longer in production, we source compatible cross-reference components and validate performance before installing. We also fabricate custom encoder interface cables to exact ADL specifications.
How do I send my ADL 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 ADL 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 ADL 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 ADL 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.
