HISO Product Lines We Repair
Our engineers are trained on the full HISO product range. Below are the major product families we service.
HV Series AC Servo Amplifiers
High-voltage servo drive amplifiers for industrial motors. Common faults include encoder signal loss, over-current trips during acceleration, and thermal protection activation in dusty factory environments. HISO HV drives are prevalent in Indian textile and packaging machinery.
MV Stepper Motor Drivers
Compact microstepping drivers for CNC machines, printing presses, and assembly automation. Repair focus includes phase winding shorts, controller communication timeouts, and step-pulse input synchronization failures common in retrofitted Indian industrial equipment.
NC-series Motion Controllers
Networked motion controllers for multi-axis synchronization in packaging, labeling, and automotive sub-assembly lines. Typical failures: Ethernet module faults, trajectory interpolation crashes, and firmware corruptions after power surges common in Indian grid environments.
EC Series Encoder Modules
Incremental and absolute encoder feedback modules for closed-loop servo systems. Frequent issues: SSI/CANopen signal dropout, connector corrosion in humid Indian factories, and signal conditioning circuit failures causing servo instability.
PG-series Parameter Generators
Hand-held programming interfaces and parameter backup units for HISO drives. Common faults: LCD display failures, EEPROM read-write errors, and communication cable intermittency in industrial field conditions.
Why Choose Synchronics for HISO Repairs?
PCB-Level Expertise

Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common HISO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HISO equipment arriving at our workshop.
- ✓Encoder signal loss - no feedback to servo — Encoder connector oxidation or shielding degradation is the leading cause in Indian high-humidity factory environments. SSI/CANopen cable continuity loss under vibration also triggers this fault in retrofit installations.
- ✓Over-current shutdown during acceleration ramp — Inadequate acceleration time settings for HISO MV drivers cause phase current spikes exceeding 150% rated. Mechanical friction or brake drag in spindle or press systems exacerbates the condition.
- ✓Thermal protection activated repeatedly — Poor heatsink contact, inadequate cooling airflow in Indian monsoon-dust environments, and continuous high-duty cycles in automotive assembly lines cause HISO amplifier die temperatures to exceed 85°C thresholds.
- ✓Servo fault E03 or E05 - control loop instability — Servo gain parameters (Kp, Ki) mismatched to motor/load dynamics after retrofitting. Grid voltage fluctuations (180V-240V swings common in rural India) destabilize phase-lock loops in HISO NC controllers.
- ✓Stepper stall - missed step count during operation — Over-temperature motor coils, over-speed commanded beyond HISO MV driver switching frequency limits, or inadequate step-pulse signal amplitude from legacy CNC controllers in Indian machine shops.
- ✓Firmware corruption - drive unresponsive to commands — Power loss during parameter write cycle, surge transients from Indian grid instability, or corrupted bootloader from third-party parameter tools. HISO drives lack battery-backed NVRAM protection.

Frequently Asked Questions — HISO Repairs
Do you repair HISO equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full HISO product range — AC servo amplifiers, stepper drivers, motion controllers, and encoder modules across all specifications. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, and all other major cities. Same-facility turnaround in Vadodara, Gujarat. Call +91-265-2766666 for logistics support.
What HISO fault codes does Synchronics repair?+
We diagnose and resolve HISO error codes including E01 (phase loss), E03 (feedback fault), E05 (servo instability), E10 (over-current), E12 (thermal protection), E20 (encoder timeout), and E30 (parameter corruption). Each code is traced to root cause — electrical, mechanical, or firmware — using oscilloscope and thermal imaging diagnostics.
Can you reprogram HISO drives with custom servo parameters?+
Yes. Synchronics holds HISO parameter engineering expertise for HV and MV series. We re-tune Kp/Ki gains for new motor/load combinations, adjust acceleration profiles to prevent stall, and configure multi-axis synchronization for NC controllers. All parameter sets are validated under loaded test conditions before return.
How fast is HISO drive repair turnaround at Synchronics?+
Standard HISO repair turnaround is 5-7 working days from receipt. Encoder and parameter module repairs complete in 2-3 days. For critical production downtime, we offer same-day diagnostic reports and expedited repair at no extra cost. Urgent spares are available from our in-stock component inventory.
Do you provide HISO drive firmware upgrades and bootloader recovery?+
Yes. Synchronics performs HISO firmware reprogramming via in-circuit boundary-scan and ROM recovery techniques. We upgrade to latest firmware versions to fix known bugs and patch security issues. Bootloader recovery from corrupted state is our standard procedure — no data loss. Full firmware validation testing is included.
How do I send my HISO 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 HISO 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 HISO 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 HISO 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.
