AALTER Product Lines We Repair
Our engineers are trained on the full AALTER product range. Below are the major product families we service.
AALTER AC Series PLC
Programmable logic controllers for discrete and process automation. Common failures include input/output module burnout, power supply degradation, and internal relay contact wear. Memory corruption and communication port failures also occur in older units.
AALTER Motion Control Modules
Servo drive and stepper motor control units for precision positioning. Typical repair needs include MOSFET/IGBT failure, encoder feedback loss, current sensor malfunction, and thermal management issues in high-duty applications.
AALTER Fieldbus Coupler & Gateway
Industrial communication interface cards for PROFIBUS, CANopen, and EtherCAT networks. Failures manifest as loss of node communication, baudrate negotiation errors, galvanic isolation breakdown, and optical coupler degradation in harsh environments.
AALTER Power Supply Units
Regulated DC power modules (24V, 48V) for distributed automation. Common defects include electrolytic capacitor swelling, voltage regulation IC failure, transformer secondary winding breakdown, and input protection relay sticking.
AALTER Human-Machine Interface (HMI) Terminals
Touchscreen and keypad operator panels for plant floor control. Repair issues include LCD panel degradation, touchscreen calibration loss, internal power conversion failures, and communication port corrosion from moisture ingress.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common AALTER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AALTER equipment arriving at our workshop.
- ✓AALTER AC Series PLC input module failure — Extended exposure to electrical noise and voltage spikes in Indian textile mills and foundries causes input optocoupler degradation and photodiode failure, preventing signal recognition from field sensors.
- ✓AALTER Motion Control servo drive overheating shutdown — In high-ambient-temperature Indian pharma and chemical plants, inadequate heatsink contact, thermal paste degradation, and internal cooling fan failure cause the drive to thermal-throttle and lose torque output.
- ✓AALTER fieldbus coupler communication timeout errors — Dust ingress, connector corrosion, and galvanic isolation capacitor aging in humid Indian manufacturing environments—particularly in sugar mills and textile dyeing units—disrupt PROFIBUS or CANopen packet transmission.
- ✓AALTER power supply output voltage drift below tolerance — Electrolytic capacitor ripple current stress, voltage reference IC aging, and transformer core saturation in old units cause 24V outputs to sag, affecting downstream PLC input reliability.
- ✓AALTER HMI touchscreen loss of responsiveness or dead zones — Moisture condensation, temperature cycling, and corrosion of the touch controller IC connections in humid Indian coastal plants and rainwater-exposed outdoor control enclosures degrade capacitive touch sensing.
- ✓AALTER PLC memory corruption / program loss after power loss — Aging backup battery failure combined with low-quality capacitor banks in power supply means the PLC cannot preserve SRAM contents during brown-out events common in Indian industrial power grids.

Frequently Asked Questions — AALTER Repairs
Do you repair AALTER equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full AALTER product range—PLCs, motion controllers, fieldbus modules, power supplies, and HMI terminals. We offer pan-India door-to-door pickup from Mumbai, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Pune, Kolkata, and all tier-2 cities. Equipment is serviced in our Vadodara, Gujarat facility and returned with 6-month warranty.
What is the typical turnaround time for AALTER PLC repair at Synchronics?+
Standard AALTER PLC repairs take 5–7 working days after receipt, including diagnostics, board-level repair, and full functional testing. Express service (3-day) is available for critical production failures. We maintain stock of common replacement modules and capacitor packs to accelerate repairs for Indian textile and pharma plants running tight production schedules.
Can Synchronics repair AALTER motion control servo drives with encoder feedback faults?+
Yes, absolutely. We specialize in AALTER MC-series servo drive repair, including encoder input circuit restoration, signal conditioning amplifier replacement, and MOSFET bridge rebuilding. We test drives under simulated load and verify encoder feedback stability before return, ensuring precise positioning performance for Indian automotive and precision manufacturing clients.
Do you provide AALTER PLC firmware updates and parameter re-commissioning after repair?+
Yes. Synchronics provides firmware re-flash, program restoration from backup files, and parameter re-commissioning as part of our AALTER repair service. If you have the original GSD files or parameter backups, we can restore your exact configuration. We also support program reconfiguration for customers unable to provide original code—common in older Indian plant installations.
What is your warranty on AALTER equipment repairs?+
All Synchronics AALTER repairs carry a 6-month comprehensive warranty covering parts and labor for the repaired function. Extended 12-month warranty is available on request. We also offer a 30-day money-back guarantee if the unit fails to meet agreed performance specs—rare, given our rigorous test protocols on Indian temperature and humidity conditions.
How do I send my AALTER 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 AALTER 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 AALTER 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 AALTER 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.
