KEP Equipment We Repair — By Category
KEP Product Lines We Repair
Our engineers are trained on the full KEP product range. Below are the major product families we service.
KEP SERVODRIVE Series
High-performance servo drives for CNC machine tools and automated assembly systems. Common faults include encoder communication loss, overcurrent shutdown, and position loop instability causing production halts.
KEP MOTIONCONTROL PLC Module
Compact motion control logic for multi-axis synchronized applications. Repair issues involve I/O module failures, timing synchronization loss, and program memory corruption affecting textile and packaging lines.
KEP NEXMOTION Stepper Driver
Cost-effective stepper motor drivers for industrial OEM equipment. Typical faults include phase winding shorts, step/direction signal interface failure, and thermal shutdown under sustained load conditions.
KEP ACMOTOR Drive Controller
AC induction motor control units for conveyor systems and fan drives. Common failures involve capacitor degradation, IGBTswitch damage, and thermal sensor malfunction triggering false overload faults.
KEP EtherCAT Gateway Module
Industrial fieldbus interface for real-time distributed motion control. Repair focus includes Ethernet PHY layer issues, CAT5e cable termination problems, and firmware synchronization errors in synchronized multi-drive setups.
Why Choose Synchronics for KEP Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on KEP equipment.
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 KEP Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KEP equipment arriving at our workshop.
- ✓Encoder communication loss SERVO drive failure — KEP SERVODRIVE units experience shielded encoder cable degradation near motor mounting or connector oxidation at the drive's encoder input terminal block. Vibration and thermal cycling in machine tool enclosures accelerate wire breakage.
- ✓Overcurrent shutdown false trigger during acceleration — KEP SERVODRIVE current sense circuits drift due to aging shunt resistors or improper tuning of servo loop gains during installation. Mechanical load spikes at startup exceed miscalibrated thresholds causing nuisance trips.
- ✓MOTIONCONTROL PLC module I/O port dead after power surge — KEP MC-series input optocouplers or output relay drivers are damaged by nearby inductive load switching transients or inadequate suppression diodes on solenoid circuits in textile mill environments.
- ✓Stepper driver phase winding short circuit NX-SD series — KEP NEXMOTION stepper drivers fail when moisture ingress combined with vibration causes insulation breakdown between motor phase windings inside the drive's power output section. Common in high-humidity food processing and pharmaceutical facilities.
- ✓EtherCAT synchronization timeout every 30-60 seconds — KEP EGW gateway module experiences jitter in Ethernet clock recovery when cable runs exceed 50m or when industrial radio frequency (RF) sources are located nearby. Firmware version mismatch between gateway and master control also triggers sync loss.
- ✓AC motor drive IGBT gate drive circuit failure thermal shutdown — KEP AC-series drives used in Indian cotton mills experience gate driver IC failures due to thermal stress combined with inadequate heatsink surface contact. Dust accumulation and insufficient cooling ventilation reduce thermal dissipation capacity.

Frequently Asked Questions — KEP Repairs
Do you repair KEP equipment anywhere in India?+
Yes. Synchronics repairs the complete KEP product range including SERVODRIVE, MOTIONCONTROL, NEXMOTION, and EtherCAT gateway modules. We offer door pickup from every major Indian city — Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, and beyond. All repairs are done at our 180+ engineer facility in Vadodara, Gujarat with 5-10 day turnaround.
What is the typical cause of KEP SERVODRIVE overcurrent faults in Indian machine tools?+
KEP servo drives in Indian CNC shops frequently trip overcurrent due to misconfigured acceleration ramps that don't match machine inertia, or degraded encoder feedback causing position loop instability. Our engineers recalibrate the servo loop, verify encoder signal integrity, and reprogram motion profiles using KEP's commissioning software to eliminate nuisance trips.
Can you repair KEP stepper drivers with burned-out phase windings?+
Yes. We replace damaged H-bridge MOSFETs and phase driver ICs, then apply conformal coating to protect against moisture — critical for textile mills and food plants. Each repaired stepper driver is tested under load before return to confirm phase-to-phase isolation and torque output.
How do you handle KEP EtherCAT synchronization issues in multi-axis setups?+
We diagnose sync timeout errors by verifying Ethernet cable quality (CAT6 compliance), installing ferrite suppression, and matching firmware versions between KEP gateway and your master controller. We then validate cycle time stability under production-like load using oscilloscope measurement.
What warranty do you offer on KEP drive repairs?+
Synchronics provides a 12-month comprehensive warranty on all KEP servo drive, motion controller, and stepper driver repairs covering parts and labor. Defects found in warranty period are repaired or replaced at no cost. Extended 24-month warranties are available for critical production equipment.
How do I send my KEP 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 KEP 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 KEP 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 KEP 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.
