KEB Equipment We Repair — By Category
KEB Product Lines We Repair
Our engineers are trained on the full KEB product range. Below are the major product families we service.
COMBIVERT Frequency Inverters
KEB's flagship AC drive family offering scalable power ratings from fractional to multi-megawatt. Common issues include capacitor degradation under thermal stress, firmware corruption in humid Indian environments, and CAN/Profibus communication faults. COMBIVERT units operate in 400V three-phase industrial plants across textiles, cement, and sugar production.
MULTI Servo Amplifiers
Precision servo drive systems for synchronized multi-axis machinery. Repair focus includes resolver interface failures, encoder cable shielding degradation, phase loss detection errors, and PWM output stage faults. MULTI drives are critical in packaging lines, printing machinery, and CNC metal-working operations throughout Indian manufacturing.
KEDRIVE Embedded Drive Controllers
Compact, integrated motion controllers combining inverter and logic functions in one unit. Common faults: software lockups after power surges, SD card corruption, Ethernet port failures, and temperature sensor drift. Widely deployed in Indian food processing, pharmaceutical manufacturing, and material handling systems.
MAZO DC Brush Drive Systems
Robust DC drive technology for legacy and new installations requiring simple, field-proven control. Repair issues include armature winding shorts, field coil burnout, thyristor base drive circuit failure, and analog reference card drift. MAZO drives remain prevalent in Indian railway workshops, steel mills, and heavy equipment manufacturers.
KECONTROL Operator Panels and HMI
Human-machine interfaces and control panels integrating KEB logic with industrial fieldbus communication. Repair work addresses touchscreen layer delamination, backup battery failures, Modbus RTU interface corruption, and DC power supply module faults under high ambient temperature conditions.

Common KEB Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KEB equipment arriving at our workshop.
- ✓KEB COMBIVERT capacitor dry-out and voltage collapse — Electrolytic filter capacitors in KEB inverters degrade rapidly in high-temperature Indian manufacturing plants (40°C+ ambient). Moisture ingress and thermal cycling accelerate dielectric breakdown, particularly in units without climate control or proper ventilation.
- ✓KEB COMBIVERT E26 / E27 error codes with drive lockout — E26 (phase loss / unbalanced supply) and E27 (phase reversal) errors occur commonly in Indian industrial sites with aging three-phase transformer banks, undersized mains cabling, or diesel genset supply. KEB's sensitive input monitoring triggers false trips during grid instability.
- ✓MULTI servo encoder communication timeout and loss of synchronization — Resolver or digital encoder cable runs in Indian plants often share conduit with main motor power cables, causing EMI coupling. Flexing crane duty cycles and vibration-induced connector micro-fractures degrade signal integrity on KEB's proprietary encoder protocols.
- ✓KEDRIVE F0 / F1 Ethernet port and SD card slot intermittent faults — Mechanical stress from repeated cable insertion, salt spray corrosion in coastal Indian plants (Gujarat, Maharashtra sea-facing installations), and conformal coating degradation expose PCB copper traces to oxidation and micro-fractures.
- ✓KEB MAZO DC thyristor base drive circuit failure—no armature current — Inadequate heatsinking and lack of forced air cooling in Indian foundries and rolling mills allow thyristor junction temperatures to exceed safe limits. Gate drive transformers saturate and fail, leaving the thyristor permanently off despite command signals.
- ✓KEB KECONTROL touchscreen delamination and Modbus RTU communication loss — High humidity and temperature cycling in Indian food processing and dairy plants cause glass-to-LCD adhesive failure. Simultaneous RS485 termination resistor dry-solder joints develop under vibration, breaking Modbus node connectivity on the plant network.

Frequently Asked Questions — KEB Repairs
Do you repair KEB equipment anywhere in India?+
Yes, Synchronics repairs the full KEB product range—COMBIVERT frequency inverters, MULTI servo amplifiers, KEDRIVE embedded controllers, MAZO DC drives, and KECONTROL HMI panels. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, and all other major cities. Your KEB drives are serviced in our central facility in Vadodara, Gujarat, with turnaround time typically 5-10 business days depending on fault severity.
What are the most common KEB COMBIVERT failures Synchronics encounters in Indian plants?+
Electrolytic capacitor dry-out (accelerated by 40°C+ ambient temperatures and poor cooling airflow) and input voltage monitoring errors (E26 / E27) are the top two issues we repair. Capacitors fail within 3-5 years in tropical Indian climates unless equipped with cabinet dehumidification. Synchronics replaces degraded capacitor banks with premium tropical-rated components and recalibrates supply voltage thresholds to reduce nuisance trips from grid instability common in rural Indian industrial areas.
Do you stock genuine KEB spare parts for fast repair turnaround?+
Synchronics maintains a dedicated KEB spare parts inventory—capacitors, thyristors, encoder connectors, Ethernet PHY modules, and common firmware cards. For stock items, repair dispatch is 2-3 days. For non-stock specialized components, we coordinate directly with KEB's German factory and regional distributors to minimize wait time. All replacement parts carry full warranty and factory traceability documentation.
How do KEB MULTI servo drives fail in Indian packaging and printing machinery?+
MULTI servo faults in Indian OEMs typically stem from encoder cable EMI coupling (improper cable routing next to motor power), thermal stress in inadequately cooled control cabinets, and resolver winding insulation breakdown after monsoon humidity ingress. Synchronics re-routes encoder cables in shielded conduit, upgrades cabinet cooling, and replaces resolver assemblies with factory-matched units. We perform full multi-axis synchronization testing before return to ensure seamless integration with customer machinery.
Can Synchronics repair KEB drives remotely or test them online before dispatch?+
Yes. Synchronics can conduct preliminary remote diagnostics if you provide KEB fault codes, control signal logs, or photo of error display. Full online repair is possible for firmware reloads and parameter resets. However, hardware faults (capacitor, thyristor, encoder interfaces) require physical inspection and component replacement in our lab. We advise on which faults can be addressed remotely versus requiring shipping. Real-time troubleshooting calls with our KEB-specialist engineers are available to help stabilize production while repair is in progress.
How do I send my KEB 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 KEB 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 KEB 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 KEB 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.
