ALW Product Lines We Repair
Our engineers are trained on the full ALW product range. Below are the major product families we service.
ALW M-Series Motion Controllers
Real-time motion control platforms for multi-axis machining and assembly. Common failures include encoder interface faults, PWM output card degradation, and firmware corruption from power surges.
ALW CPL Programmable Logic Controllers
Modular PLC systems for process automation and discrete manufacturing. Typical issues: I/O module failures, communication card faults (Profibus/EtherCAT), battery backup failure affecting retention memory.
ALW ServoLink Servo Drive Systems
Closed-loop servo amplifiers for precision positioning and velocity control. Common defects: capacitor bank ageing, resolver feedback circuit noise, gate driver IC burnout from load transients.
ALW ProComm Industrial Communication Modules
Gateway and protocol converter modules for EtherCAT, PROFINET, and CANopen networks. Failures often stem from network surge damage, optical port degradation, or bootloader corruption.
ALW PowerSync Distributed I/O Terminals
Remote digital and analogue I/O modules for decentralised plant architectures. Prone to field-wiring transient damage, relay contact wear, and analogue input channel offset drift.
Why Choose Synchronics for ALW Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on ALW equipment.
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 ALW Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALW equipment arriving at our workshop.
- ✓ALW Motion Controller Encoder Interface Failure — EMI from nearby welding or induction heating damages the differential encoder input amplifier on M-Series controllers. Shielding degradation or improper grounding allows noise to corrupt position feedback signals.
- ✓CPL PLC Profibus Communication Card Lockup — ALW CPL Profibus modules (CPL-32/64) occasionally freeze under network surge or collision-heavy bus conditions. Repeated slave timeouts trigger firmware watchdog resets, causing intermittent drops in real-time data.
- ✓ServoLink Capacitor Bank Electrolytic Failure — Harsh Indian ambient temperatures (40-50°C in machinery rooms) accelerate aluminium electrolytic capacitor ageing in ALW ServoLink servo drives. Ripple current overload from overdriven axes stresses capacitors, leading to leakage and eventual short-circuit.
- ✓ProComm EtherCAT Optical Port Signal Loss — ALW ProComm modules (PC-ETH, PC-DUAL) deployed in dusty textile mills or cement plants suffer optical connector fouling and fibre misalignment. Sudden loss of EtherCAT slave communication halts synchronised motion.
- ✓ALW Motion Controller EEPROM Data Corruption — Power supply brownout or abrupt power-off during firmware programming corrupts ALW M-Series controller configuration memory. System boots with invalid motor parameters, causing servo instability and axis runaway.
- ✓PowerSync Analogue Input Channel Offset Drift — ALW PowerSync AI modules exposed to high humidity or vibration experience op-amp reference voltage drift. Temperature hysteresis in component layouts causes reported analogue values to deviate 2-5% from true input, destabilising process control loops.

Frequently Asked Questions — ALW Repairs
Do you repair ALW equipment anywhere in India?+
Yes, Synchronics repairs the complete ALW product portfolio — motion controllers, PLCs, servo drives, communication modules, and I/O terminals. We offer PAN India door pickup from major metros including Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all tier-2 cities. All repairs are performed in our ISO-certified facility in Vadodara, Gujarat.
What is the typical turnaround time for ALW M-Series motion controller repair?+
Standard ALW motion controller diagnosis and repair takes 5-7 working days. Encoder amplifier replacement takes 2-3 days; firmware restoration from 1-2 days. For time-critical applications, we offer expedited 24-48 hour repair with rush charges. Synchronics maintains stock of common ALW spare boards and components.
Can you repair ALW controllers with corrupted firmware?+
Absolutely. ALW M-Series and CPL controllers with corrupted EEPROM are our specialty. We use JTAG boundary-scan programming to bypass non-functional bootloaders, restore factory firmware, and reload your backed-up parameter configurations. Even bricked units can usually be recovered without component replacement.
Do you stock spare parts for ALW drives and modules?+
Synchronics maintains active inventory of common ALW replacement modules: servo drive power sections, Profibus/EtherCAT communication cards, analogue input modules, and encoder interface boards. For rare or obsolete ALW parts, we source directly from European suppliers within 10-15 days. Field repairs often completed same-day from stock.
What warranty do you provide on ALW repairs?+
All Synchronics ALW repairs include 12 months warranty on replaced components and labour. For servo drives and power modules, we extend coverage to field failures under normal industrial use. Warranty excludes damage from external surges, overload, or misapplication. Extended warranties available upon request.
How do I send my ALW 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 ALW 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 ALW 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 ALW 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.
