INFASE Product Lines We Repair
Our engineers are trained on the full INFASE product range. Below are the major product families we service.
INFASE Soft Starters (CFW Series)
Electronic soft starting systems that reduce inrush current and mechanical stress on motors. Common faults include thyristor firing circuit failures, temperature sensor malfunctions, and control board capacitor dry-out in high-ambient Indian environments.
INFASE Variable Frequency Drives (AFS Series)
Compact and rugged VFDs for pump, fan, and compressor applications with integrated DC chokes and EMC filters. Typical repair needs involve IGBT module failures, encoder interface issues, and cooling fan bearing wear.
INFASE Power Factor Correction (PFC Series)
Automated capacitor-based power factor correction units with harmonic filtering for compliance with Indian electricity board standards. Capacitor swelling, thyristor short circuits, and control relay sticking are frequent failure modes.
INFASE Harmonic Filters and Reactors
Passive and active harmonic mitigation systems for industrial facilities with heavy VFD and non-linear loads. Repair focuses on inductor winding insulation breakdown, capacitor bank degradation, and capacitive voltage divider failures.
INFASE Control Panels and Interface Modules
Integrated control panels featuring INFASE electronics, operator interfaces, and protection relays for motor starter systems. Common issues include relay contact erosion, potentiometer drift, and solder joint cracking due to vibration.

Common INFASE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in INFASE equipment arriving at our workshop.
- ✓Soft starter thyristor firing circuit breakdown — INFASE soft starters operate continuously in Indian textile and sugar mills with frequent on-off cycles. Gate drive circuits degrade due to thermal cycling and moisture ingress, causing thyristors to remain permanently ON or OFF. Pulse transformer insulation breakdown is common.
- ✓Capacitor swelling and electrolyte leakage — INFASE VFDs and soft starters use aluminium electrolytic capacitors that degrade rapidly in Indian ambient temperatures exceeding 40-45°C. High switching frequencies (16 kHz typical) generate core heat; inadequate ventilation in tropical climates accelerates capacitor failure.
- ✓IGBT module junction failure and paralleling imbalance — INFASE AFS-Series VFDs pair IGBTs in parallel for higher current rating. Current imbalance due to gate drive skew or solder joint fatigue causes one IGBT to conduct more heavily, leading to thermal runaway and junction melt in one module of the pair.
- ✓Power factor correction capacitor bank resonance and tripping — INFASE PFC systems are subject to harmonic distortion from VFD loads in Indian sugar and cement plants. Capacitor bank natural frequency aligns with harmonic orders, causing resonance, over-voltage conditions, and nuisance relay trip-outs. Contactor coil wear prevents proper bank discharge.
- ✓Encoder interface and motor speed feedback loss — INFASE closed-loop VFDs use optical or magnetic encoders for field-oriented control. Bearing wear, connector corrosion from sweat and humidity, and EMI from adjacent unshielded cables cause intermittent or total speed feedback loss, triggering fault codes F2.0 or F4.1.
- ✓Control relay contact chatter and stiction in starter contactors — INFASE control panels in Indian mills experience rapid on-off cycling and high ambient dust. Relay coils wear, contacts develop carbon buildup and mechanical stick, or armature springs lose tension — all causing erratic motor enable/disable sequences and unexpected motor stalls.

Frequently Asked Questions — INFASE Repairs
Do you repair INFASE equipment anywhere in India?+
Yes. Synchronics repairs the full INFASE product range — soft starters, variable frequency drives, power factor correction units, and harmonic filters. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Kolkata, and all other cities. Central facility in Vadodara, Gujarat with 48-72 hour repair turnaround for most INFASE equipment.
What is the typical cause of INFASE soft starter thyristor failure in Indian industrial plants?+
INFASE soft starters fail primarily due to thermal cycling and moisture ingress in high-ambient (40-45°C) Indian factory environments. Gate drive transformer insulation breaks down, thyristor firing pulses become erratic, and the starter either locks ON (causing motor stall) or locks OFF (no motor start). Synchronics replaces gate drive boards, tests all thyristors under rated current, and applies conformal coating for lasting humidity resistance.
Can you repair INFASE power factor correction panels with capacitor bank failure?+
Absolutely. INFASE PFC capacitor banks are vulnerable to harmonic resonance in plants with multiple VFDs. Synchronics diagnoses harmonic distortion using power quality measurement, replaces failed capacitors and contactors, and retuning the detuning reactor to prevent resonance. We reprogram protection relay thresholds and deliver a stable, compliant power factor exceeding 0.95 as per Indian electricity board standards.
What warranty does Synchronics offer on INFASE repairs?+
Synchronics provides a 12-month warranty on all component replacements and 6 months on repaired units. Labor and retest are included. If a repaired INFASE drive or soft starter fails within warranty due to manufacturing defect in our repair, we re-repair at no charge or provide replacement credit. Warranty excludes damage from customer installation errors or electrical surges.
Do you stock original INFASE spare parts and modules?+
Yes. Synchronics maintains inventory of common INFASE replacement modules including thyristor stacks, IGBT modules, gate drive boards, and capacitor banks. For rare or obsolete INFASE parts, we arrange import from authorised Brazilian distributors with typical 5-7 day lead time. Critical components are available under expedited order within 48 hours for emergency plant restarts.
How do I send my INFASE 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 INFASE 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 INFASE 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 INFASE 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.
