AYDIN CONTROLS Product Lines We Repair
Our engineers are trained on the full AYDIN CONTROLS product range. Below are the major product families we service.
Series 2000 Servo Drive Family
Analogue servo amplifiers for precision motion control in legacy systems. Common faults include capacitor ageing, thermal runaway, and encoder feedback signal loss due to connector corrosion in industrial environments.
Series 5000 Digital Motion Controller
Digital position and velocity controllers with multi-axis capability. Failure modes include firmware corruption, power supply degradation under transient loads, and I/O module isolation failures in high-EMI factory floors.
Analog Feedback Processing Modules
Signal conditioning and feedback linearisation electronics for potentiometric and resolver feedback. Typical issues are zero-drift in DAC output, reference voltage instability, and input filter capacitor ESR failure causing bandwidth loss.
Power Supply Modules (PSM Range)
Regulated DC and AC power supplies for servo and control circuits. Indian manufacturing plants report PSM failures due to voltage sag, harmonic distortion from non-linear loads, and inadequate thermal management in tropical climates.
Velocity and Torque Monitor Interface
Real-time dynamic monitoring and fault logging electronics for servo loop supervision. Common failures include memory corruption in event log, watchdog timer drift, and analogue input offset errors.

Common AYDIN CONTROLS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AYDIN CONTROLS equipment arriving at our workshop.
- ✓Series 2000 Capacitor Bank Dry-Out and ESR Rise — Aydin Controls servo amplifiers from the 1980s-2000s used electrolytic capacitors susceptible to electrolyte evaporation in high-temperature Indian factory environments. ESR increase destabilises the feedback loop, causing oscillation and eventual driver shutdown.
- ✓Series 5000 Firmware Corruption and Boot Failure — Power interruptions, brownouts, and transient spikes on Indian industrial power grids can corrupt the EEPROM in Series 5000 digital controllers, preventing normal boot sequence and system initialisation.
- ✓Encoder Feedback Signal Loss and Intermittent Faults — Aydin Controls servo systems rely on incremental or absolute encoders for position feedback. Connector corrosion, cable chafing, and EMI coupling from VFDs on the same plant floor cause intermittent signal loss and CRC errors in feedback telemetry.
- ✓Analogue Feedback Module DAC Offset and Zero-Drift Error — AFM series reference voltage stability is compromised by supply ripple, temperature drift in precision resistors, and aging of thin-film resistor networks. This causes proportional band errors and steady-state position offsets in closed-loop systems.
- ✓Power Supply Module Undervoltage Shutdown Under Load Transients — Indian factories experience frequent grid sag, voltage flicker, and harmonic distortion. Aydin Controls PSM modules with marginal regulation margin shut down unnecessarily, halting production. Weak filtering and limited hold-up time worsen the issue.
- ✓Velocity and Torque Monitor Watchdog Timer Drift and False Alarms — VTMI module crystal oscillators age and drift at different rates than the servo loop clock, causing watchdog timer to trigger false fault conditions. Temperature cycling in uncontrolled Indian factory environments accelerates drift.

Frequently Asked Questions — AYDIN CONTROLS Repairs
Do you repair Aydin Controls equipment anywhere in India?+
Yes. Synchronics repairs the full Aydin Controls product range — servo drives, motion controllers, feedback modules, and power supplies. We offer pan-India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 cities. All repairs are performed at our factory in Vadodara, Gujarat, with fast turnaround and full diagnostic reports.
What is the typical repair cost and turnaround time for Aydin Controls servo amplifiers?+
Aydin Controls servo amplifier repair costs range from INR 8,000 to INR 35,000 depending on fault severity and component replacement needs. Most faults are diagnosed and repaired within 3-5 working days. Catastrophic failures (burnt output transistors, shorted transformers) may require sourcing specialist components and take up to 7-10 days. Synchronics provides free preliminary diagnostics and a written repair quote before proceeding.
How do I know if my Aydin Controls Series 2000 or 5000 controller is worth repairing versus replacement?+
Synchronics evaluates repair viability based on PCB condition, parts availability, and age of equipment. Most Series 2000 and 5000 controllers are economical to repair — we typically restore 85-90% of failed units to full operational status. We provide a repair cost estimate and expected lifespan post-repair so you can make an informed decision. For equipment >30 years old, we explore refurbishment and performance upgrades.
Do you stock Aydin Controls replacement boards and spare parts?+
Synchronics does not stock new Aydin Controls boards, as the company is now predominantly used in legacy systems. However, we maintain a library of donor boards and salvaged components from returned equipment. For critical repairs, we source NOS (new old stock) modules and original components through our international supplier network, typically within 5-7 working days. We also perform component-level repairs and PCB rework for obsolete modules.
Can Aydin Controls equipment be upgraded or retrofitted to modern servo technology?+
Yes. Many Indian textile mills, precision machine shops, and automotive suppliers still rely on legacy Aydin Controls systems. Synchronics designs hybrid retrofits — replacing ageing servo amplifiers with modern SIEMENS or DANFOSS drives while preserving existing encoders, motors, and control logic. We provide complete system integration, commissioning, and operator training. This approach extends machine life 15+ years at a fraction of full equipment replacement cost.
How do I send my AYDIN CONTROLS 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 AYDIN CONTROLS 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 AYDIN CONTROLS 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 AYDIN CONTROLS 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.
