LUST Product Lines We Repair
Our engineers are trained on the full LUST product range. Below are the major product families we service.
LUST Synchronous Motor Controllers
Closed-loop servo control systems for high-precision positioning in textile machinery and machine tools. Common faults include encoder signal loss, thermal runaway, and commutation phase shift errors that cause vibration and position drift.
LUST Frequency Converters & VFDs
3-phase AC drive systems for fan, pump, and compressor applications across Indian industrial facilities. Repair challenges include DC bus capacitor aging, IGBT gate driver failures, and CAN/Profibus communication timeouts.
LUST Servo Amplifiers
Dual-axis and multi-channel amplifier modules for OEM machine tool builders. Prone to resolver breakdown, PWM output transistor failure, and current sense circuit drift — especially in high-vibration packaging line environments.
LUST Embedded Industrial PCs & I/O Modules
Real-time embedded controllers with analog I/O, relay output, and fieldbus interfaces for textile loom and automotive assembly line sequencing. Common failures include SD card corruption, RTC battery failure, and relay contact welding.
LUST Resolver & Encoder Interface Cards
Precision feedback signal conditioning modules for motor position feedback loops. Failures stem from resolver coil insulation breakdown, cable shield corrosion in humid textile mill environments, and ADC bit depth degradation.
LUST Safety-Rated Control Modules
SIL2/SIL3-certified safety logic modules used in automotive assembly machinery and machine tool interlocks across Indian OEM lines. Diagnosis requires certified safety function testing and dual-channel redundancy verification.

Common LUST Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LUST equipment arriving at our workshop.
- ✓Resolver signal dropout and encoder loss — LUST synchronous motors rely on precision resolver or incremental encoder feedback. In Indian textile mills and automotive plants with high EMI environments, resolver coil insulation degradation and connector corrosion cause intermittent signal loss, triggering E-stop logic.
- ✓IGBT gate driver failure and shoot-through events — LUST frequency converter IGBT modules degrade under thermal cycling common in Indian summer conditions. Gate driver optocoupler decay causes cross-conduction, generating destructive shoot-through events that cascade secondary IGBT failure.
- ✓Commutation phase shift and vibration — LUST servo controllers derive commutation angle from resolver feedback. Phase drift occurs when resolver excitation voltage droops, COS/SIN signal attenuates, or firmware calibration constants corrupt — causing 15-30 degree phase error and audible cogging.
- ✓DC bus capacitor aging and voltage sag — LUST frequency converters use 470-1000uF aluminum electrolytic capacitors rated 450-550VDC. In Indian industrial environments with ambient >40°C, capacitor ESR rises and capacitance falls 30-50% within 5-8 years, causing output voltage ripple and soft-fault codes.
- ✓CAN bus and Profibus communication timeouts — LUST embedded industrial PCs communicate over CAN 2.0B or Profibus DP fieldbus to slave I/O modules. Cable shield discontinuity, stub termination mismatch, and corrupted transceiver firmware cause frame loss and machine halt.
- ✓Relay contact welding and output module failure — LUST I/O relay modules rated 16A inductive load degrade under Indian industrial switching loads. Transient voltage spikes, arcing, and contact material migration cause relay contacts to weld or fail open, disabling critical interlocks in textile loom and automotive assembly lines.

Frequently Asked Questions — LUST Repairs
Do you repair LUST equipment anywhere in India?+
Yes. Synchronics repairs the full LUST product range — synchronous motor controllers, frequency converters, servo amplifiers, embedded PCs, and resolver interface cards — all 22+ products in our catalog. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other metro and tier-2 cities. Repair happens in our ISO 9001 facility in Vadodara, Gujarat, with typical turnaround 5-7 working days.
What is the typical cost and timeline for LUST servo amplifier repair?+
LUST servo amplifier repair costs INR 8,000-25,000 depending on fault complexity — resolver recalibration, IGBT replacement, or full analog board replacement. Diagnostics are free and non-invasive. We charge only for parts and labor after fault confirmation. Turnaround is 5-7 days from receipt. Warranty is 12 months parts and labor.
Can Synchronics repair LUST resolver encoder feedback systems?+
Yes. LUST precision resolver and incremental encoder interfaces are core to our repair capability. We perform full resolver winding insulation testing (megohm measurement), COS/SIN signal amplitude and phase verification, encoder quadrature pulse verification, and re-calibration using LUST proprietary software. Common resolver failures in Indian textile mills are fixed within 3-4 days.
Do you stock LUST spare parts — capacitors, IGBTs, relays, optocouplers?+
Synchronics maintains stock of common LUST replacement components including 450VDC electrolytic and film capacitors, IGBT modules (1200V/600A), relay coils, gate driver optocouplers, and resolver connectors. We source directly from German suppliers via our established logistics network, ensuring 99% authentic parts. Lead time for rare modules is 5-10 days.
How does Synchronics test LUST frequency converter repairs before shipment?+
Every repaired LUST frequency converter undergoes 48-hour continuous burn-in under simulated load (1.5x rated power) on our test stand. We measure DC bus voltage ripple, output three-phase harmonics, thermal stability, and communication protocol throughput. Full diagnostic report with scope captures is provided. This ensures zero-defect returns to Indian automotive and textile plants.
How do I send my LUST 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 LUST 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 LUST 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 LUST 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.
