TROY ENTEREPRISE CO LTD Equipment We Repair — By Category
TROY ENTEREPRISE CO LTD Product Lines We Repair
Our engineers are trained on the full TROY ENTEREPRISE CO LTD product range. Below are the major product families we service.
TROY SM Series Servo Drives
Compact servo amplifiers for motion control in textile looms, packaging machines, and CNC equipment. Common faults include capacitor aging, encoder signal loss, and thermal runaway under load cycling.
TROY VF Series Variable Frequency Drives
Three-phase AC motor drives rated 0.5-75 kW for pump, fan, and conveyor applications. Field failures often stem from DC bus overvoltage, IGBT switching faults, and sensorless vector control instability.
TROY MC Series Motion Controllers
Multi-axis industrial controllers for synchronized machine operations in printing, weaving, and material handling. Repair issues include firmware corruption, I/O card failure, and fieldbus communication dropout.
TROY RS Series Regenerative Servo Systems
Energy-recovery servo solutions for high-speed repetitive machinery common in Indian automotive and consumer appliance manufacturing. Prone to capacitor bank derating and AC line harmonic distortion.
TROY EX Series Explosion-Proof Drives
ATEX/IECEx rated servo and variable frequency drives for sugar mills, oil processing, and chemical plants operating in hazardous zones. Enclosure seal degradation and potted winding moisture ingress are primary repair drivers.

Common TROY ENTEREPRISE CO LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TROY ENTEREPRISE CO LTD equipment arriving at our workshop.
- ✓DC Bus Overvoltage Trip on VF Series — Regenerative braking energy from motor deceleration exceeds drive capacitor absorption capacity, common in Indian textile spinning and winding applications where rapid motor stops are frequent. Undersized braking resistors or missing resistor networks cause voltage spikes to 850V+.
- ✓Encoder Signal Loss in SM Servo Drives — Incremental encoder cabling degradation due to vibration in high-speed packaging and converting lines. EMI from large contactors and soft-starters causes encoder pulse counting errors and servo loop instability.
- ✓IGBT Module Failure with Thermal Shutdown — Thermal cycling in ambient temperatures above 45°C (common in Indian foundries and sugar plants) combined with aluminum heatsink corrosion and TIM (Thermal Interface Material) degradation reduces heat dissipation. Over-current spikes from locked motor conditions accelerate IGBT junction stress.
- ✓Firmware Corruption in MC Motion Controllers — Power transients during grid voltage surges or improper shutdown sequences corrupt flash memory in TROY controllers. Lightning strikes and load shedding in Indian industrial areas trigger spontaneous firmware resets.
- ✓Fieldbus Communication Timeout (CANopen/EtherCAT) — Loose or corroded M12 connectors in production floor environments, or improperly terminated fieldbus segments in multi-machine installations. TROY controllers are sensitive to impedance mismatches and stub length violations.
- ✓Potted Winding Moisture Ingress in EX Series — Condensation in explosion-proof enclosures from rapid temperature swings in tropical Indian climate (sugar mills, oil refineries) causes moisture to penetrate polyurethane potting compound. Salt air and chemical vapor environments accelerate degradation.

Frequently Asked Questions — TROY ENTEREPRISE CO LTD Repairs
Do you repair TROY ENTERPRISE equipment anywhere in India?+
Yes. Synchronics repairs TROY servo drives, VFDs, and motion controllers across India with PAN-India door pickup from all major cities — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and others. Our main repair facility in Vadodara, Gujarat stocks TROY spare parts and offers 24-48 hour standard turnaround. We also provide on-site emergency repairs for critical production machines.
What is the typical turnaround time for TROY SM servo drive repair?+
Standard service is 48 hours from receipt to dispatch. SM servo drives undergo component-level diagnostics, capacitor and IGBT testing, firmware validation, and 2-hour full-load burn-in on our test benches. Express 24-hour service is available for emergency textile mill stoppages. We track TROY servo repairs using barcode systems for transparency.
Can Synchronics repair TROY EX explosion-proof drives and maintain ATEX certification?+
Yes. Our technicians are trained on ATEX and IECEx assembly, testing, and documentation protocols. When repairing TROY EX series drives, we use only certified potting compounds, perform Group II Category 3 compliance verification, and issue full ATEX certification paperwork. Potted modules are sourced from TROY-approved vendors to preserve explosion-proof integrity.
What should I do if my TROY VF drive shows E-OV (overvoltage) error codes?+
E-OV errors on TROY VF series indicate DC bus voltage exceeded 750V, typically from regenerative braking energy. First, check if a dynamic braking resistor is installed and its rating. Send the drive to Synchronics for immediate inspection — we'll measure DC bus capacitor ESR, verify braking resistor specifications, and likely upsize your capacitor bank. We also review your motor deceleration profiles and recommend firmware parameter changes to reduce voltage spikes.
Do you stock replacement capacitors and IGBT modules for TROY drives?+
Yes. Synchronics maintains genuine TROY-compatible industrial-grade capacitors (Nippon Chemi-con, Rubycon) rated for 85°C and above, and IGBT modules from Infineon and Fuji Electric matched to TROY specifications. We source EX series potted modules directly through TROY's authorized Indian distributors to ensure ATEX compliance. Lead times for stocked components are same-day; special industrial grades are 3-5 working days.
How do I send my TROY ENTEREPRISE CO LTD 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 TROY ENTEREPRISE CO LTD 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 TROY ENTEREPRISE CO LTD 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 TROY ENTEREPRISE CO LTD 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.
