CARVAN Product Lines We Repair
Our engineers are trained on the full CARVAN product range. Below are the major product families we service.
CARVAN Stepper Motor Drives
Microstepping and full-step driver boards controlling NEMA and IEC stepper motors. Common failures include transistor burnout, encoder interface faults, and phase-shift errors causing loss of position accuracy. Motor holding current instability and thermal shutdown issues frequent in high-ambient Indian textile facilities.
CARVAN Motion Controller Units
Compact PLC-based motion controllers with pulse-train outputs and closed-loop feedback integration. Prone to firmware corruption, real-time clock battery failure, and stepper pulse synchronization errors affecting multi-axis coordination in printing and labeling machinery.
CARVAN Servo Drive Amplifiers
Single and dual-axis servo amplifiers for AC servo motors in precision positioning applications. Failures include gate-driver MOSFET short-circuits, back-EMF detection calibration loss, and encoder signal conditioning board degradation in dusty factory environments.
CARVAN Encoder Interface Cards
Quadrature and incremental encoder signal conditioning and isolation boards. Common faults are opto-coupler failures, signal comparator drift, and connector corrosion causing missed encoder pulses and position loss in real-time systems.
CARVAN Stepper Power Supply Modules
Regulated 24VDC and 48VDC supplies with current-limiting protection for multi-motor stepper applications. Failure modes include switching transistor burnout, secondary-side rectifier failure, and electrolytic capacitor drying causing brownout conditions and motor holding force loss.

Common CARVAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CARVAN equipment arriving at our workshop.
- ✓Stepper motor phase loss or stuttering movement — CARVAN DK-series drive output transistors fail short-circuit due to repeated surge currents from inductive motor winding kickback or inadequate snubber diode protection. Thermal stress from poor heatsink contact accelerates failure in Indian summer heat.
- ✓Position accumulation error or axis drift during long print runs — CARVAN MCS motion controller internal clock drifts, or step-pulse synchronization firmware degrades after firmware update or power-cycle corruption. Encoder feedback noise in electrically noisy Indian factories causes missed quadrature counts.
- ✓Servo drive LED fault indicators with no motor response — CARVAN SVA servo amplifier gate-driver ICs fail, disabling MOSFET switching despite valid command signals. Encoder connection pins corroded by humidity or vibration exposure cause open-circuit feedback preventing servo loop closure.
- ✓Encoder interface card intermittent signal loss or random axis jumps — CARVAN ENC-series opto-coupler LED efficiency degrades over time, reducing signal-to-noise margin below safe thresholds. PCB trace corrosion from salt air exposure in coastal Indian manufacturing facilities breaks differential signal paths.
- ✓Repeated power supply brownout or motor holding force loss during idle — CARVAN PSU secondary-side electrolytic capacitors dried out from thermal stress, reducing output filter capacitance by 40-60 percent. Aging causes peak current delivery to fail during stepper motor micro-stepping current transients.
- ✓Microstepping resolution loss or coarse movement instead of fine increments — CARVAN stepper driver DAC (digital-to-analog converter) reference voltage drifts or reference resistor network develops thermal intermittent contacts, degrading current accuracy. Multi-motor systems suffer cross-talk through power supply common-mode noise.

Frequently Asked Questions — CARVAN Repairs
Do you repair CARVAN equipment across all of India?+
Yes. Synchronics maintains PAN India repair service for CARVAN stepper drives, servo amplifiers, motion controllers, and encoder interface systems. We offer free courier pickup from Mumbai, Delhi, Bangalore, Hyderabad, Pune, Chennai, Ahmedabad, Kolkata, and all other Indian cities. Repairs are performed in our Vadodara facility with 3-7 day turnaround and comprehensive post-repair testing.
What is the typical repair cost for a CARVAN stepper motor drive failure?+
CARVAN stepper drive repair costs range from INR 4,500-12,000 depending on fault severity. Output transistor burnout and phase loss repairs typically cost INR 6,000-8,000. Complex firmware corruption or encoder interface damage runs INR 9,000-12,000. Synchronics provides free diagnosis and written quotation within 24 hours. Most repairs include 12-month warranty covering same component failure.
How do I know if my CARVAN motion controller can be repaired or needs replacement?+
CARVAN motion controller firmware corruption, clock failure, and stepper pulse generation errors are readily repaired by Synchronics. Reprogramming, oscillator re-calibration, and output stage restoration typically restore 95%+ of failed units. If the microprocessor itself is damaged or CPLD logic failure is confirmed, we advise replacement. Send your unit for free diagnosis—we'll provide a clear repair vs. replace recommendation within 48 hours.
Can Synchronics repair CARVAN drives that have been previously repaired by other technicians?+
Absolutely. Synchronics frequently restores CARVAN equipment damaged by inexperienced repair attempts. We remove solder bridges, replace incorrectly soldered components, rebuild damaged PCB traces, and restore proper thermal management. We perform full electrical testing and component-level verification—restoring your drive to factory specification regardless of prior history.
What makes CARVAN stepper motors fail in Indian manufacturing environments?+
CARVAN stepper drives in Indian factories fail primarily from thermal stress (ambient heat without proper ventilation), electrical surges from unprotected induction motor loads, humidity-induced corrosion in coastal facilities, and inadequate power supply filtering in electrically noisy facilities. Textile mills and packaging plants experience highest failure rates due to continuous 24/7 operation and high dust exposure. Synchronics repairs all CARVAN failure modes and recommends protective measures—EMI filtering, isolated 24VDC supplies, and thermal management upgrades—to prevent recurrence.
How do I send my CARVAN 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 CARVAN 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 CARVAN 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 CARVAN 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.
