AICHI KEISOH CO Product Lines We Repair
Our engineers are trained on the full AICHI KEISOH CO product range. Below are the major product families we service.
Aichi Keisoh Servo Drives
AC and DC servo amplifiers for precision motion control. Common repairs include encoder interface failures, IGBT module burnout, and firmware corruption in legacy models. Critical for textile machinery and injection moulding equipment.
Motion Control Modules
Programmable motion controllers and pulse generators for multi-axis positioning. Typical faults include timing circuit degradation, connector oxidation, and communication protocol loss between modules.
Encoder Systems and Feedback Interface
Incremental and absolute encoder interfaces, signal conditioners, and converter modules. Common issues include shielding degradation, connector pin corrosion, and analog-to-digital conversion errors in noisy factory environments.
Power Stage Modules
Transistor and IGBT output stages for high-current servo applications. Frequent failures: thermal runaway, solder joint cracking under vibration, and gate drive circuit faults in Indian humidity-prone installations.
Legacy Analog Control Systems
Older potentiometer-based controllers and analog feedback circuits. Repair challenges include capacitor leakage, potentiometer wear, and noise immunity in retrofitted machinery across India's textile and pump sectors.

Common AICHI KEISOH CO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AICHI KEISOH CO equipment arriving at our workshop.
- ✓Encoder interface signal loss or drift — Aichi Keisoh encoder conditioners are sensitive to cable shielding degradation and connector corrosion in high-vibration Indian factory environments. Moisture ingress in coastal facilities accelerates pin oxidation.
- ✓Servo drive not responding to command pulses — Aichi Keisoh SD-series drives lose pulse recognition due to input optocoupler failure or corrupted firmware. Common in older machines retrofitted with modern PLC systems generating non-standard pulse widths.
- ✓IGBT module thermal shutdown during operation — Power stage thermal management fails in Aichi Keisoh servo modules due to solder joint cracking under cyclic vibration, or capacitor dry-out reducing heat dissipation efficiency in the power PCB.
- ✓Motion controller firmware corruption or boot failure — Aichi Keisoh MC-series controllers experience power supply transients or incomplete program uploads, leaving firmware in corrupted state. Frequent in Indian facilities with unstable electrical supply or improper shutdown procedures.
- ✓Analog feedback signal noise or offset error — Legacy Aichi Keisoh analog controllers suffer from capacitor ageing and ground plane separation, creating noise coupling from adjacent motor cables. EMI from unshielded power lines in older Indian factories worsens the issue.
- ✓Communication timeout between motion modules — Aichi Keisoh multi-axis systems drop inter-module communication due to failed isolation transformers, damaged RS-485 transceivers, or corrupted serial firmware handshake protocol.

Frequently Asked Questions — AICHI KEISOH CO Repairs
Do you repair Aichi Keisoh servo drives and motion controllers across India?+
Yes. Synchronics Electronics maintains PAN-India service for all Aichi Keisoh product families. We collect faulty equipment from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and 500+ Indian cities via our logistics partner. Repairs are completed in our Vadodara, Gujarat facility and returned within 7-10 working days. Express service available.
What is the typical lead time for Aichi Keisoh servo amplifier repair?+
Standard turnaround is 7-10 working days from receipt. We prioritise diagnostic testing (24 hours), component sourcing (2-3 days), repair and testing (2-3 days). For critical failures in Indian production lines, we offer 48-hour express repair at 40% premium. Synchronics maintains a stock of common Aichi Keisoh replacement modules including power stages, encoder interfaces, and control PCBs.
Can Synchronics repair older Aichi Keisoh analog servo controllers from 1990s-era textile machinery?+
Absolutely. Synchronics specialises in legacy Aichi Keisoh analog systems widely installed in Indian textile mills and packaging lines. We source rare potentiometers, capacitors, and transformers, and perform component-level repairs on vintage boards. Our engineers have restored machines dating back 25+ years. We provide technical documentation and spare part recommendations for long-term operation.
Do you test Aichi Keisoh encoder interfaces with actual encoder hardware before return?+
Yes. Synchronics tests all repaired Aichi Keisoh encoder interface modules using calibrated incremental and absolute encoders under simulated load conditions. We verify zero-offset, pulse accuracy, and signal integrity over full operational range (0-5000 RPM typically). Custom test setups are available for non-standard encoder protocols.
What warranty do you provide on Aichi Keisoh servo drive repairs?+
Synchronics offers 12 months warranty on all labour and replaced components for Aichi Keisoh repairs. We guarantee proper functionality under original equipment specifications and Indian industrial operating conditions (temperature 10-40C, humidity up to 80%). Warranty excludes damage from power surges, mechanical shock, or water ingress after repair delivery.
How do I send my AICHI KEISOH CO 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 AICHI KEISOH CO 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 AICHI KEISOH CO 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.
