TECO Equipment We Repair — By Category
TECO Product Lines We Repair
Our engineers are trained on the full TECO product range. Below are the major product families we service.
N3-Series AC Drives
TECO's entry-level scalar and V/F control VFDs (0.4–22 kW) widely used in pumps, fans, and compressors. Common faults: capacitor ripple, cooling fan motor failure, phase loss detection circuit malfunction, and firmware corruption from power surges.
N7-Series Vector Control Drives
TECO's advanced sensorless vector drives (0.4–55 kW) for precision spindles, extruders, and metal processing. Deliver high starting torque and dynamic load response. Repairs include speed feedback circuit failures, encoder signal loss, DC bus voltage instability, and rotor parameter reset.
EFC 3000 Series HMI and Control Panels
TECO's industrial human-machine interface terminals (5–10 inch touchscreen) used in batch processes and real-time monitoring. Common issues: touch sensor malfunction, memory corruption, communication port failure (RS485, Modbus), and power supply ripple.
TECO Soft Starters (TS Series)
Solid-state soft starters (5.5–160 kW) for reducing inrush current in large motor loads. Faults include thyristor gate drive circuit failure, control input signal noise immunity loss, and overtemperature sensor drift.
TECO Servo Amplifiers and Motors
Closed-loop servo systems for precision positioning in printing, packaging, and textile machinery. Repair challenges: Hall sensor signal degradation, current loop instability, encoder feedback cable shielding loss, and triac commutation failure.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common TECO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TECO equipment arriving at our workshop.
- ✓N3/N7 series capacitor dry-out and ripple failure — Indian tropical humidity and ambient temperatures (35–48°C) in factory floors accelerate electrolytic capacitor drying. Ripple voltage rises, triggering over-voltage shutdown or intermittent drive restart.
- ✓TECO VFD speed instability and hunting oscillation — Improper V/F curve tuning for Indian 3-phase 415V unstable grid (voltage fluctuation ±10%), loose motor cable shielding causing feedback noise, or encoder resolution mismatch in vector mode.
- ✓TECO soft starter thyristor gate drive short circuit — Moisture ingress in humid environments, solder joint cracks from vibration in cement/steel mills, or gate resistor carbon tracking from repeated soft-start surges.
- ✓N7 vector drive rotor parameter loss and speed feedback failure — Power surges during monsoon grid disturbances erase EEPROM rotor constants. Encoder cable breaks or connector oxidation in textile mills cause sensorless operation failure and loss of torque control.
- ✓TECO HMI touchscreen unresponsiveness and display flicker — Dust and moisture ingress under touchscreen glass, power supply ripple exceeding 5V tolerance, or Flash memory CRC error from sudden power loss during firmware upload.
- ✓TECO servo amplifier current loop instability and thermal shutdown — Inadequate PWM heatsink cooling in compact servo cabinets, hall sensor Hall IC degradation reducing commutation accuracy, or incorrect current sense resistor tolerance (1% vs 5%) causing over-current false trips.

Frequently Asked Questions — TECO Repairs
Do you repair TECO equipment anywhere in India?+
Yes. Synchronics repairs the full TECO product range — N3 and N7 drives, soft starters, servo amplifiers, and HMI terminals. We offer PAN-India door pickup and drop from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Indore, Nagpur, and all other cities. Service hub in Vadodara, Gujarat. Same-day diagnostics and 5-7 day turnaround for most TECO repairs.
What is the typical repair cost for a TECO N3 or N7 VFD?+
TECO drive repair cost ranges 15,000–45,000 INR depending on fault severity and spare parts required. Capacitor and cooling fan replacement runs 18,000–28,000 INR. Vector drive encoder or gate driver IC replacement costs 30,000–50,000 INR. We provide upfront quote and parts breakdown. Genuine TECO spares are stocked; repair takes 5–7 days. Warranty: 12 months on repaired unit.
Can you help if my TECO drive shows E-07, E-11, or E-14 fault codes?+
Absolutely. E-07 is over-current (check motor short/ground), E-11 is over-voltage (grid spike), E-14 is over-temperature (fan failure or ambient heat). Synchronics decodes TECO fault codes, performs motor insulation test, checks DC bus capacitors, and clears error flags only after root cause is fixed. We document fault logs and provide remediation advice to prevent recurrence in your plant.
Do you offer TECO drive parameter backup and restoration service?+
Yes. Before repair, we back up all TECO drive parameters (V/F curve, acceleration ramp, encoder Km, soft-start threshold) to our server using official TECO parameter loader tool. If firmware is corrupted, we restore from backup. If parameters are lost, we use your motor nameplate to rebuild rotor constants. We also provide printed parameter sheets for your maintenance team's reference.
What is your experience repairing TECO servo systems in textile and printing machinery?+
Synchronics has repaired 150+ TECO servo drives in Indian textile mills, rotogravure printing presses, and packaging lines over the past 15 years. We specialize in closed-loop servo tuning for precision spindle speed control, dancer arm feedback circuits, and multi-axis synchronization. Our technicians understand jitter, cogging torque, and phase lag issues specific to Indian ambient temperatures and 415V grid disturbances. We work with OEM suppliers and mill maintenance teams to restore uptime quickly.
How do I send my TECO 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 TECO 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 TECO 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 TECO 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.
