HAUNI Product Lines We Repair
Our engineers are trained on the full HAUNI product range. Below are the major product families we service.
HAUNI PROTOS Series
High-speed cigarette making and packing lines. Common faults include servo encoder failures, drive communication errors, and pneumatic valve control malfunctions. Requires precision calibration after repair.
HAUNI Motion Control Systems
Synchronized stepper and servo drive modules for tobacco leaf feeding and cutting systems. Prone to encoder signal loss, stepper motor coil burnout, and PLC communication timeouts in high-humidity factory environments.
HAUNI CUTTIN Series
Tobacco cutting and homogenization equipment with integrated PLC and frequency inverters. Common issues: blade vibration sensor faults, inverter thermal failures, and encoder drift in continuous-duty operations.
HAUNI Baling and Storage Systems
Automated tobacco bale handling and storage automation. Frequent faults: DC motor drive overload, solenoid valve coil shorts, proximity sensor degradation, and PLC input module failures.
HAUNI Leaf Feeder Control Electronics
Precision feeder systems for tobacco leaf distribution. Issues include encoder cable breakage, stepper motor phase failures, analog signal noise in sensor inputs, and firmware corruption.
HAUNI Packaging Line Interface Modules
Network-connected control interfaces and HMI boards for integration with factory MES. Prone to Ethernet port damage, relay card burnout, and real-time OS crashes under thermal stress.

Common HAUNI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HAUNI equipment arriving at our workshop.
- ✓Servo encoder signal loss or intermittent dropout — HAUNI equipment runs 24/7 in tobacco dust environments. Encoder cable insulation degrades, connectors corrode, or the encoder disk becomes contaminated with tobacco particles and moisture. This causes the servo drive to lose position feedback.
- ✓Motion control synchronization timeout errors — HAUNI MCS (Motion Control Systems) rely on precise inter-axis timing. PLC communication delays, corrupted firmware in motion modules, or real-time OS crashes cause synchronization faults, leading to product jams and line shutdown.
- ✓Frequency inverter thermal shutdown and nuisance tripping — HAUNI CUTTIN equipment draws peak current during leaf cutting cycles. Inverters in humid, dust-laden factories experience heatsink clogging, fan bearing wear, and capacitor ESR drift — triggering temperature cutouts even under normal load.
- ✓Proximity sensor signal intermittency or complete failure — HAUNI baling and leaf feeder systems use inductive/capacitive proximity sensors for tobacco bale position and flow detection. Sensor cables get pinched by machinery vibration, cable screens corrode, or sensor faces accumulate tobacco dust layer that blocks sensing.
- ✓PLC input/output module card failure or slot burnout — HAUNI packaging line PLC cabinets endure sudden load spikes when solenoid valves fire, electrical surges during power transients, and moisture ingress from condensation. I/O module relay contacts weld or fail, or backplane traces burn.
- ✓Stepper motor coil burnout and loss of step integrity — HAUNI leaf feeder and motion control systems run stepper motors continuously. Phase coil insulation fails due to moisture and thermal cycling, or the stepper driver IC outputs get shorted by vibration-induced connector contact bounce, causing full coil burnout.

Frequently Asked Questions — HAUNI Repairs
Do you repair HAUNI equipment anywhere in India?+
Yes. Synchronics repairs the complete HAUNI control electronics portfolio — servo drives, motion controllers, PLC modules, frequency inverters, and packaging line interfaces. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all major cities. All repairs are performed in our ISO-certified Vadodara facility with same-day diagnostics and 5-7 day turnaround on most units.
What is the typical turnaround time for HAUNI PROTOS servo drive repair?+
HAUNI PROTOS servo drives are critical — we prioritize these. Standard diagnostics take 24 hours. If capacitors or power stage is involved, 3-5 days. If encoder or resolver replacement is needed, add 2-3 days for calibration. We offer expedited service for tobacco factories with backup lines — we can often loan a tested spare while yours is being repaired, keeping your downtime to zero.
Can Synchronics repair HAUNI motion control modules if I do not have original firmware?+
Yes. Even without your original firmware image, Synchronics has archived HAUNI firmware versions for MCS-8, MCS-16, and MCS-Advanced modules. We contact HAUNI service in Germany if needed. We also perform reverse-engineering of EEPROM data to recover your original parameter set. Once repaired and flashed, we run all modules on our test harness to verify motion sync before you take delivery.
What preventive maintenance do you recommend for HAUNI packaging line electronics in Indian factories?+
HAUNI equipment thrives on prevention. We recommend: (1) quarterly encoder cable and connector inspection, (2) annual heatsink and cooling fan cleaning, (3) semi-annual capacitor ESR testing on inverters, (4) sensor face wipe-down every 3 months (tobacco dust accelerates failure), and (5) PLC module reseating annually. Synchronics offers scheduled PM contracts for tobacco factories — we conduct on-site audits and generate preventive work orders, reducing unplanned downtime by 60-70%.
Do you stock HAUNI spare parts or replacement modules?+
Synchronics maintains a stock of common HAUNI replacement modules — encoder assemblies, relay cards, filter capacitors, and servo motor connectors. For critical items like PROTOS servo drives or MCS motion modules, we can source spares from HAUNI service partners in Europe within 7-10 days. We also refurbish and certify faulty HAUNI modules that our customers bring in, offering 40-50% cost savings versus new parts while maintaining warranty.
How do I send my HAUNI 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 HAUNI 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 HAUNI 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 HAUNI 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.
