JAQUIER + LEHMANN Product Lines We Repair
Our engineers are trained on the full JAQUIER + LEHMANN product range. Below are the major product families we service.
Jaquier + Lehmann Servo Drive Systems
Compact, high-precision servo drive modules designed for positioning, spindle control, and synchronisation applications. Common faults include EEPROM corruption, power stage failures, and encoder communication loss requiring specialised calibration during repair.
Electromechanical Positioning Actuators
Swiss-built linear and rotary positioning systems with integrated feedback. Repairs typically involve stepper coil testing, lead screw backlash diagnosis, and resolver/encoder recalibration to restore positioning accuracy within tolerances.
Control Interface Modules
Fieldbus-compatible control boards (Profibus, CANopen) for Jaquier + Lehmann motion systems. Typical issues include communication timeouts, relay failures, and analogue input signal conditioning faults requiring firmware updates and component-level repair.
Spindle Drive Electronics
Three-phase AC and DC spindle drive units for precision grinding and machining equipment. Repairs address capacitor dry-out, thyristor stack testing, speed regulation drift, and thermal sensor replacement.
Integrated Motion Controllers
Multi-axis motion coordination platforms combining servo management with PLC-style logic. Common faults include flash memory exhaustion, inter-axis synchronisation loss, and analogue/digital I/O module failures.

Common JAQUIER + LEHMANN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in JAQUIER + LEHMANN equipment arriving at our workshop.
- ✓Servo drive EEPROM parameter corruption — Jaquier + Lehmann servo drives store calibration and gain parameters in EEPROM. Power surges, interrupted programming sequences, or age-related flash degradation corrupt this memory, causing erratic axis movement or complete drive disable. Indian manufacturing sites with unstable power supply experience this frequently.
- ✓Encoder or resolver signal loss mid-cycle — Jaquier + Lehmann positioning systems rely on high-resolution encoders or resolvers. Vibration-induced connector micro-fractures, cable abrasion in high-speed applications, or feedback module IC failure result in lost position data and E-stop activation. Common in textile, packaging, and precision engineering plants.
- ✓Power stage transistor or MOSFET stack failure — Jaquier + Lehmann servo drives use robust but thermally-sensitive power stages. Overload conditions, inadequate heatsink contact, or internal coolant leakage in liquid-cooled systems cause junction temperature runaway and catastrophic transistor failure, resulting in output short or open circuit.
- ✓Profibus or CANopen communication timeout — Jaquier + Lehmann control interface modules use Swiss precision connectors prone to oxidation and vibration-loosening in industrial environments. Firmware version mismatches between main drive and fieldbus module also cause intermittent communication loss.
- ✓Capacitor dry-out and voltage regulation failure — Jaquier + Lehmann drive and spindle controller boards use long-life aluminium electrolytic capacitors rated for 85-105 degrees Celsius. In Indian heat-prone environments without adequate cooling, electrolyte evaporation causes ESR rise, voltage ripple increase, and eventual capacitor failure within 3-5 years of operation.
- ✓Positioning accuracy drift beyond process tolerance — Jaquier + Lehmann electromechanical positioners accumulate lead screw backlash and bearing preload loss over time. Thermal expansion differences between steel and brass components in high-cycle applications cause hysteresis buildup, degrading repeatability below the required +/- micron tolerance.

Frequently Asked Questions — JAQUIER + LEHMANN Repairs
Do you repair Jaquier + Lehmann equipment anywhere in India?+
Yes. Synchronics repairs the full Jaquier + Lehmann product range — servo drives, electromechanical positioners, spindle controllers, and motion interface modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major industrial cities. All repairs are processed at our central facility in Vadodara, Gujarat, with 48-hour turnaround for standard faults.
What makes Jaquier + Lehmann servo drives difficult to repair compared to other brands?+
Jaquier + Lehmann drives embody Swiss precision design with tightly-toleranced feedback systems and proprietary EEPROM calibration data. Incorrect parameter restoration or misaligned servo loop gain tuning can render the drive unusable. Synchronics maintains authentic Swiss calibration libraries and performs functional testing on loaded servo systems to match the original OEM performance envelope. This level of precision is essential for applications requiring +/- 0.1mm positioning repeatability.
Can you source genuine Jaquier + Lehmann spare parts and modules?+
Synchronics maintains authorised supplier relationships for Jaquier + Lehmann original components, including power modules, encoder feedback cards, and control interface boards. For obsolete parts (pre-2005 models), we perform cross-component analysis and functional equivalencing with tested industrial alternatives. Lead times for Swiss-origin parts are typically 10-14 days; we expedite orders for critical production shutdowns.
How do I know if my Jaquier + Lehmann drive can be repaired or needs replacement?+
Synchronics provides free diagnostic evaluation. We test power stage functionality, EEPROM integrity, feedback signal quality, and communication module health. Drives with repairable faults (capacitor replacement, connector refurbishment, firmware update) typically represent 70-80% cost savings versus new units. Only drives with multiple cascade faults (power stage + control board failure) or physically cracked PCBs are uneconomical to repair. We provide a detailed repair cost estimate before proceeding.
What is the typical repair turnaround time for Jaquier + Lehmann servo drive failures?+
Standard Jaquier + Lehmann servo drive repairs (power stage failure, capacitor replacement, encoder recalibration) take 5-7 working days. Complex faults involving EEPROM corruption, multi-module testing, or thermal bench validation extend to 10-12 days. Synchronics offers express 48-hour service for documented production emergencies, with priority parts expediting and weekend technician availability. All repairs include 12-month component-level warranty.
How do I send my JAQUIER + LEHMANN 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 JAQUIER + LEHMANN 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 JAQUIER + LEHMANN 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 JAQUIER + LEHMANN 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.
