LS ELECTRIC Equipment We Repair — By Category
LS ELECTRIC Product Lines We Repair
Our engineers are trained on the full LS ELECTRIC product range. Below are the major product families we service.
LSIS iG5A VFD Series
Compact, high-performance variable frequency drives for 0.75-37 kW AC motors. Common issues include capacitor failure, IGBT module burnout, and communication faults in networked installations typical of Indian food processing and cement plants.
LS ELECTRIC Soft Starter G3 Series
Three-phase soft starters for motor inrush current control in textile mills and pump stations. Failures typically involve thyristor degradation, cooling fan blockage in dusty Indian plant environments, and firmware corruption.
LSIS GLOFA PLC Series
Compact and modular programmable logic controllers widely deployed in auto-component manufacturing and packaging lines. Repair needs include memory backup battery replacement, communication module failures, and I/O card burnout from electrical transients.
LS ELECTRIC Low-Voltage Switchgear & Contactors
Industrial contactors, thermal overload relays, and distribution panels for 20A-1000A applications. Common faults include coil insulation breakdown, contact welding, and arc suppression circuit failures in high-ambient Indian industrial settings.
LS ELECTRIC HMI Panels
Human-machine interface touch panels (7-inch to 15-inch displays) for process visualization and control. Repair issues include TFT backlight failure, capacitive touchscreen unresponsiveness, and power supply module degradation.
LS ELECTRIC Servo Drives & Motors
Compact servo systems for precision positioning in woodworking, printing, and pharmaceutical machinery common to western Indian manufacturing clusters. Failures include encoder cable breakage, power stage shorts, and firmware update issues.

Common LS ELECTRIC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LS ELECTRIC equipment arriving at our workshop.
- ✓LS ELECTRIC iG5A VFD display goes blank — Electrolytic capacitor failure on the control board power supply, accelerated by ambient temperature exceeding 45-50°C typical in Indian foundries and steel plants without adequate HVAC. High dust ingress also causes cooling fin blockage and overheating.
- ✓LS ELECTRIC soft starter thyristor short circuit — Thyristor gate isolation breakdown due to voltage spikes during motor starting transients, especially in Indian textile mills with poor earthing infrastructure or adjacent heavy welding equipment. Moisture ingress into hybrid module accelerates this failure.
- ✓GLOFA PLC memory contents lost after power cycle — Backup battery (CR2032) depletion or connection corrosion on the CPU board — this is a time-dependent failure (typically 3-5 years) in Indian plants without uninterruptible power supply. Solder joint cracking around battery holder due to thermal cycling also occurs.
- ✓LS ELECTRIC contactor coil won't de-energize or chatters — Coil insulation failure causing partial short turns, or mechanical stiction in the armature guide due to iron oxide buildup and moisture — common in humid coastal Indian plants or those with poor control enclosure sealing. Contact welding from arc flash also prevents separation.
- ✓LS ELECTRIC HMI touchscreen unresponsive or erratic cursor — Capacitive touch sensor degradation from high humidity (>80% RH) in Indian pharmaceutical and food plants, or static electricity accumulation on display surface. Internal digitizer calibration drift also causes intermittent responsiveness.
- ✓LS ELECTRIC servo drive alarm code E-1 or E-2 (encoder/power fault) — Encoder cable shield grounding at both ends causing ground loop noise, or physical cable wear near motor connector from continuous machine vibration — typical in woodworking planers and printing equipment. Power stage half-bridge failure also triggers these codes.

Frequently Asked Questions — LS ELECTRIC Repairs
Do you repair LS ELECTRIC equipment anywhere in India?+
Yes. Synchronics repairs the complete LS ELECTRIC product range — VFDs, soft starters, PLCs, HMI panels, low-voltage switchgear, and servo systems. We offer PAN India express pickup and repair from our Vadodara, Gujarat facility. We serve customers across Mumbai, Pune, Ahmedabad, Surat, Chennai, Bangalore, Hyderabad, Delhi, Chandigarh, and all industrial cities.
What is the typical repair turnaround time for LS ELECTRIC VFDs?+
For standard LS ELECTRIC iG5A and older VFD models, turnaround is typically 5-7 working days including diagnostic testing, parts procurement, repair, and full load commissioning. Rush service (48-72 hours) is available for critical production equipment. We maintain stock of common failure modules like power stage IGBTs, control board capacitors, and firmware chips.
Do you stock genuine LS ELECTRIC spare parts?+
Yes. Synchronics maintains inventory of critical LS ELECTRIC spare parts including IGBT modules, electrolytic capacitors, contactors, thermal overload relays, and encoder cables. For obsolete parts, we source directly from authorized LS ELECTRIC distributors in South Korea and maintain a 3-week lead time guarantee for most components.
Can you repair LS ELECTRIC equipment without the original documentation or program?+
Absolutely. For LS ELECTRIC PLCs and drives, we can extract firmware and recover program memory using specialized test equipment. For soft starters and switchgear without documentation, we diagnose by reverse-engineering the schematic from board markings. However, we recommend customers maintain backup program copies to expedite repairs and avoid production downtime.
What warranty do you provide on LS ELECTRIC repairs?+
Synchronics provides 12 months' comprehensive warranty on all LS ELECTRIC repairs — covering parts, labor, and firmware integrity. Warranty covers material defects and our workmanship, but not damage from external causes (power surges, mechanical trauma, liquid ingress). Extended 24-month warranty is available on request for mission-critical equipment.
How do I send my LS ELECTRIC 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 LS ELECTRIC 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 LS ELECTRIC 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 LS ELECTRIC 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.
