KUBLER Product Lines We Repair
Our engineers are trained on the full KUBLER product range. Below are the major product families we service.
Incremental Encoders (Optisch)
Kubler incremental optical encoders with glass disk technology for position feedback. Common issues include disk contamination, LED degradation, phototransistor failure, and bearing wear causing signal dropout or noise in A/B/Z channels.
Absolute Encoders (CANopen, SSI, Profibus)
Kubler absolute multi-turn and single-turn encoders with CANopen, SSI, and Profibus interfaces for direct integration into automation networks. Faults include signal processor module failure, rotary transformer winding shorts, and interface connector oxidation.
Rotary Switches and Coded Disks
Kubler coded disk rotary switches and mechanical position indicators for manual machine tool positioning and application-specific encoding. Failure modes include contact corrosion, disk wear, shaft misalignment, and detent mechanism failure.
Optical Incremental Sensors (Sendix)
Sendix range incremental sensors for conveyor systems and packaging machinery with rugged IP67 housing. Common repairs involve shaft seal degradation, bearing play, and electronics module moisture ingress in humid textile and food-processing plants.
Torque and Angle Sensors
Kubler torque transducers and angle measurement modules for precision applications in industrial automation. Issues include amplifier PCB failures, strain gauge bridge imbalance, and connector pin corrosion in chemical and cement plant environments.
Hollow Shaft Encoders
Kubler hollow bore encoders for direct mounting on motor shafts and spindles in CNC machines and industrial robots. Repair challenges include magnetic coupling slip, bearing preload loss, and signal conditioning module failure under vibration.

Common KUBLER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in KUBLER equipment arriving at our workshop.
- ✓Incremental encoder signal loss or dropout — Optical disk contamination by dust, coolant mist, or oil vapor is the primary cause in Indian manufacturing environments. Secondary causes include LED brightness degradation, phototransistor junction damage, or bearing wear causing axial disk wobble that breaks signal alignment.
- ✓Absolute encoder CANopen communication timeout — Kubler absolute encoders commonly experience CAN transceiver IC failure, particularly in plants with poor power supply regulation or lightning-prone locations. Cold solder joints on the processor module and corroded CAN connector pins also cause intermittent bus dropout.
- ✓Bearing play and mechanical runout in encoder shaft — Extended operation in high-vibration packaging machinery (especially in pharmaceutical and FMCG plants) causes Kubler bearing preload loss and radial play. This creates disk wobble, signal noise, and eventual bearing spalling that damages the optical surfaces.
- ✓SSI signal line open or intermittent frame errors — Kubler SSI encoders fail due to shielded cable abrasion at connector exit (common in robot cable chains), corrosion of SSI differential line drivers in high-humidity textile mills, or improper termination resistor values on integrator PCBs.
- ✓Rotary transformer winding open or shorted in multi-turn encoders — Kubler absolute encoders using rotary transformer technology experience winding shorts due to insulation breakdown under moisture and thermal cycling in cement plants and steelworks. Vibration-induced fretting at winding connections also causes intermittent faults.
- ✓Connector pin oxidation causing signal noise or CAN frame loss — Kubler encoders deployed in high-chloride environments (coastal plants) and food-processing facilities with washdown cycles experience rapid contact corrosion on M12 and DIN 43650 connectors. Electrolytic corrosion is accelerated by dissimilar metals in mixed cable assemblies.

Frequently Asked Questions — KUBLER Repairs
Do you repair Kubler encoders anywhere in India?+
Yes. Synchronics Electronics repairs the full Kubler encoder and sensor range across India. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Jaipur, and all other major cities. Faulty units are brought to our Vadodara facility (Gujarat) for diagnosis, repair, and full functional testing. Typical turnaround is 5-7 days including shipping.
What is the difference between Kubler incremental and absolute encoders, and which is better for my CNC machine?+
Kubler incremental encoders output pulse trains (A/B/Z signals) and require a controller to track position from machine startup. Absolute encoders output unique codes for each shaft angle, retaining position data after power loss. For CNC machine tools, incremental encoders are cost-effective for closed-loop feedback; absolute encoders are essential for applications requiring position retention (multi-axis mills with power-off halt requirements). Synchronics can advise based on your machine architecture.
Why does my Kubler encoder output noisy signals in my packaging line?+
Signal noise in Kubler encoders is commonly caused by dust/coolant contamination on the optical disk, bearing play causing disk wobble, or worn phototransistors producing weak signal amplitude. High-vibration environments (typical in pharmaceutical packaging) accelerate bearing wear. Synchronics performs optical inspection, signal amplitude measurement, and bearing TIR check to pinpoint the cause. Most noisy-signal repairs involve disk cleaning and bearing replacement.
Can Synchronics repair Kubler CANopen encoders with intermittent CAN bus dropout?+
Yes. CANopen dropout in Kubler absolute encoders is usually caused by cold solder joints, CAN transceiver IC failure, or corroded connector pins. Synchronics performs CANopen node scan, inspects solder connections under magnification, and tests the transceiver IC with a TIA/EIA CAN analyzer. We replace failed components, clean connectors, and perform extended CANopen communication testing to ensure reliable network integration.
What is your warranty on repaired Kubler encoders?+
Synchronics provides 12 months return-to-base warranty on all repaired Kubler encoders, covering defects in workmanship and replaced components. The warranty covers optical signal integrity, CANopen/SSI communication, bearing runout, and connector function. Warranty excludes damage from mishandling, mechanical shock, or non-compliance with Kubler installation guidelines. Optional extended warranty available for mission-critical packaging and automation systems.
How do I send my KUBLER 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 KUBLER 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 KUBLER 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 KUBLER 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.
