HITA Product Lines We Repair
Our engineers are trained on the full HITA product range. Below are the major product families we service.
HITA Servo Motor Drivers
High-precision AC servo motor controllers used in automated machinery and precision positioning systems. Common failures include firmware corruption, encoder signal loss, and thermal overload detection circuits requiring specialist calibration and component-level repair.
HITA Proportional Valve Controllers
Proportional directional control and pressure reducing valve electronics for hydraulic power circuits in excavators, loaders, and crushing plant machinery. Typical repair needs include solenoid driver circuit failures, pressure transducer interface issues, and PWM signal conditioning problems.
HITA Motion Control PLCs
Compact programmable logic controllers for coordinated multi-axis motion in textile, packaging, and material handling equipment. Frequent issues include input/output module failures, communication port degradation, and battery-backed memory loss affecting program retention.
HITA Hydraulic Pump Motor Controllers
Variable displacement pump and motor control units for energy-efficient hydraulic systems in large presses, injection molding machines, and marine deck machinery. Common faults involve pressure compensator logic circuits, swashplate position feedback sensors, and load-sensing signal processing.
HITA Frequency Inverters
Industrial AC drive units for hydraulic pump motors and auxiliary equipment in textile mills and food processing plants across India. Repair challenges include IGBT module thermal stress, DC bus capacitor aging, and control transformer primary winding insulation breakdown.

Common HITA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HITA equipment arriving at our workshop.
- ✓HITA servo encoder signal loss and position feedback errors — Repeated thermal cycling in industrial environments degrades encoder cable shielding and connector pins on HITA servo motors. Vibration-induced micro-fractures in encoder PCB solder joints are common in mining and crushing equipment operating in high-vibration zones.
- ✓HITA proportional solenoid driver coil burnout and open-circuit failures — Prolonged exposure to hydraulic fluid contamination and moisture ingress causes solenoid coil insulation degradation. Spikes from proportional valve switching transients damage solenoid driver MOSFETs when protective snubber circuits fail or become ineffective over time.
- ✓HITA pressure transducer signal conditioning and ADC conversion errors — Hydraulic fluid ingress into transducer connector ports corrodes conditioning amplifier input circuits and shifts sensor calibration curves. Contaminated sensor supply voltages introduce noise that causes erratic pressure readings and false alarm shutdowns in HITA controller logic.
- ✓HITA motion control PLC flash memory corruption and program loss — Sudden power loss during program upload or unexpected mains voltage spikes corrupt HITA PLC firmware sectors. Battery-backed RAM failure during extended shutdowns causes loss of critical configuration parameters and calibration data stored in SRAM.
- ✓HITA hydraulic pump variable displacement swashplate position feedback instability — Linear position transducer drift caused by thermal expansion mismatch between sensor and mechanical linkage produces non-linear feedback signals. Swashplate centering spring fatigue and load-sensing compensator cartridge spool stiction cause oscillatory control response in HITA pump motor units.
- ✓HITA inverter DC bus capacitor ripple voltage rise and thermal runaway — Aluminum electrolytic capacitors in HITA frequency inverters age under high ambient temperatures in Indian steel mills and textile plants, causing equivalent series resistance (ESR) increase. Prolonged overload conditions and harmonic current injection accelerate capacitor aging and lead to thermal runaway conditions.

Frequently Asked Questions — HITA Repairs
Do you repair HITA equipment anywhere in India?+
Yes. Synchronics repairs the complete HITA product portfolio including servo drives, proportional valve controllers, motion control PLCs, and hydraulic pump motor units. We offer nationwide door pickup from Mumbai, Pune, Delhi, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all major Indian cities. Your HITA equipment ships to our ISO-certified repair facility in Vadodara, Gujarat for specialist diagnostics and repair.
How do HITA proportional valve controller faults affect production in Indian textile mills?+
HITA proportional valve controllers regulate hydraulic flow to coordinated spindle pressure and color dosing systems in Indian textile operations. Solenoid driver failures or pressure transducer signal loss causes uneven dyeing, product quality variation, and unplanned shutdowns. Synchronics' HITA specialists diagnose fault codes using factory diagnostic interfaces and replace failed solenoid drivers and signal conditioning circuits, restoring proportional control authority and production consistency.
What is the typical turnaround time for HITA servo drive repair at Synchronics?+
Standard HITA servo drive repair requires 8-12 working days including comprehensive diagnostics, component-level repairs, firmware verification, and multi-point functional testing. Express turnaround (4-6 days) is available for critical production shutdowns. We maintain stock of common HITA servo modules and proportional solenoid drivers to minimize repair duration for Indian manufacturing plants with tight production schedules.
Does HITA equipment repair require original spare parts or can equivalent components be used?+
Synchronics uses original HITA components wherever critical to equipment performance, especially for servo encoder modules, pressure transducers, and power stage semiconductors. For passive components and connectors, we source OEM-equivalent industrial-grade parts with matching specifications. All replacements carry component traceability documentation. We never compromise on quality for cost savings — your HITA system returns to design performance specifications.
How does Synchronics handle HITA equipment with multiple fault codes displayed simultaneously?+
Simultaneous HITA fault codes often indicate a root cause cascade rather than independent failures. Our diagnostic methodology isolates the primary failure using functional block testing — we identify whether the issue originates in power supply circuits, sensor feedback paths, or control algorithm logic. For example, a single faulty pressure transducer can trigger multiple proportional valve fault codes. Synchronics performs systematic root cause analysis before commencing repairs, ensuring the core problem is addressed rather than treating symptoms.
How do I send my HITA 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 HITA 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 HITA 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 HITA 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.
