ALLESTEC Product Lines We Repair
Our engineers are trained on the full ALLESTEC product range. Below are the major product families we service.
ALLESTEC AC Servo Drives
High-precision servo motor controllers for textile machinery, packaging equipment, and automated assembly systems. Common faults include encoder signal loss, phase imbalance detection, and thermal runaway during rapid acceleration cycles typical in Indian textile production.
ALLESTEC Industrial PLC Controllers
Compact and modular programmable logic controllers for process automation and real-time control. Repair needs often involve communication module failures, analog input card degradation, and firmware corruption in high-humidity factory environments.
ALLESTEC HMI Touch Panels
Industrial human-machine interface terminals for process monitoring and operator control. Failures typically include touchscreen unresponsiveness, internal NAND flash corruption, and communication gateway faults in chemically aggressive environments.
ALLESTEC Frequency Inverters
Three-phase variable frequency drives for pumps, compressors, and fan motors in HVAC and process cooling systems. Common issues include gate driver failures, DC bus capacitor degradation, and IGBT module thermal stress under sustained high-load operation.
ALLESTEC Communication Modules
Industrial Ethernet, Profibus, and Modbus gateways for networked automation systems. Failures arise from connector corrosion, protocol stack errors, and EMI-induced signal integrity loss in noisy factory floors.
ALLESTEC Analog I/O Boards
Precision signal conditioning and measurement cards for 4-20mA sensor inputs and 0-10V output control. Repair work typically addresses ADC drift, op-amp saturation, and DAC non-linearity after prolonged exposure to temperature extremes.

Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ALLESTEC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALLESTEC equipment arriving at our workshop.
- ✓ALLESTEC servo drive encoder communication loss — Encoder cable damage, loose M12 connectors, or corroded header pins on the drive's encoder input stage. Prevalent in dusty textile mills where vibration and humidity degrade connector contacts over time.
- ✓ALLESTEC PLC Ethernet communication timeout — Faulty RJ45 magnetics transformer, corrupted MAC firmware in the communication coprocessor, or failed isolation optocoupler. Often triggered after power surges or extended network congestion.
- ✓ALLESTEC HMI touchscreen no response to input — Internal NAND flash memory wear-out, corrupted touchscreen calibration data, or failed touch controller IC due to thermal cycling. Common in food processing plants with temperature fluctuations.
- ✓ALLESTEC inverter DC bus overvoltage trip during load release — Faulty DC bus capacitor bank allowing voltage spikes, defective regenerative braking resistor, or failed soft-stop firmware logic in the inverter's microcontroller.
- ✓ALLESTEC analog input card reading drift and non-linearity — Op-amp offset voltage drift due to thermal stress, ADC reference voltage instability, or leakage current in precision resistor networks. Particularly problematic in uncontrolled foundry and steel mill environments.
- ✓ALLESTEC communication module Profibus slave timeout errors — Shielded twisted-pair cable degradation, failing 120-ohm termination resistors, or corrupted Profibus stack in the module's microcontroller. Induced by excessive EMI from nearby welding or induction equipment.

All repairs are completed at our fully equipped 18,000 sq ft facility in Vadodara, Gujarat. Express turnaround available for critical production line repairs.
What is the typical turnaround time for ALLESTEC servo drive repair?+
Standard ALLESTEC servo drive repair takes 5-7 working days including diagnostics, component replacement, and full functional testing. For critical textile mill or packaging line shutdowns, we offer 48-hour expedited service with additional bench fees. Overnight courier pickup and delivery available across India.
Do you stock genuine ALLESTEC spare components and modules?+
Synchronics maintains inventory of authentic ALLESTEC replacement components including encoder input modules, Ethernet transformers, capacitor packs, and firmware EPROM modules. We source directly from ALLESTEC distributors to guarantee genuine parts and compatibility. All repairs use original components with full traceability for compliance audits.
Can you recover data or programs from a faulty ALLESTEC PLC?+
Yes. We specialize in ALLESTEC PLC memory recovery and firmware extraction. Even if the controller is non-responsive, our engineers can access the internal EEPROM and NAND flash to recover your ladder logic programs and configuration data. We can restore the recovered program to a repaired or replacement PLC and test it against your process specification.
What warranty do you provide on ALLESTEC repairs?+
All ALLESTEC repairs carry a comprehensive 12-month parts and labor warranty covering the repaired component. We also provide 30 days of free technical support for integration back into your production line. Optional 24-month extended warranty available for high-criticality equipment. Every repair includes detailed test reports and a performance baseline for future maintenance planning.
How do I send my ALLESTEC 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 ALLESTEC 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 ALLESTEC 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.
