BACHER Product Lines We Repair
Our engineers are trained on the full BACHER product range. Below are the major product families we service.
Bacher Proportional Valve Controllers
Electronic proportional control units for industrial hydraulic systems. Common issues include spool valve hysteresis, proportional solenoid coil burnout, feedback transducer drift, and LVDT signal loss. Prevalent in plastic injection moulding and die-casting lines.
Bacher Servo Amplifiers and Motion Controllers
Compact servo drive units for machine tool spindles and multi-axis positioning. Typical faults: gate driver failure, power stage thermal runaway, encoder signal corruption, and PID loop instability on rapid axis movement.
Bacher Machine Tool Interface Modules
Programmable control interfaces bridging legacy CNC machines to modern automation systems. Repair focus: relay contact pitting, optical isolator degradation, firmware corruption, and serial protocol timeout errors on RS-485 links.
Bacher Integrated Automation Nodes
Modular PLC-style controllers for production line synchronisation and sequence logic. Recurring faults: capacitor plague, input/output module isolation breakdown, real-time clock battery depletion, and software permission conflicts after power loss.
Bacher Feedback Transducers and Sensors
High-precision LVDT, proximity, and potentiometric position sensors for closed-loop control. Common failures: cable connector oxidation, sensing element mechanical wear, excitation voltage supply noise coupling, and nonlinear output calibration drift.
Bacher Custom Control Modules
Application-specific analog and digital control cards for foundries, forges, and textile dyeing operations. Typical repair scope: power supply regulation collapse, solid-state relay thermal cycling failure, and customer firmware debugging on embedded microcontrollers.

Common BACHER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in BACHER equipment arriving at our workshop.
- ✓Proportional solenoid coil open-circuit failure — Bacher proportional valve coils are wound on aluminium bobbins. Moisture ingress combined with thermal cycling in humid Indian factory environments causes copper wire oxidation and insulation breakdown, particularly in coastal automotive and textiles plants.
- ✓Servo amplifier MOSFET gate driver IC thermal runaway — Bacher SA-2000 and SA-3000 series amplifiers use IR2110 or Infineon gate drivers. Continuous 200+ kHz PWM switching at high ambient temperature (>45°C in Indian machine shops) causes substrate leakage current and parasitic thermal feedback, leading to cascading gate driver collapse.
- ✓Machine tool CNC interface protocol timeout and communication hang — Bacher MTI modules use legacy RS-485 with proprietary handshake timing. Electrical noise from nearby VFD cables, ground loop potential difference, and corrupted bootloader firmware after unexpected power loss cause the module to ignore commands and lock up every 2-4 hours of operation.
- ✓Integrated automation node capacitor plague and voltage regulator collapse — Bacher AUTO-Node series (2002-2010 production) used low-ESR polymer capacitors with inadequate ripple current rating. Combined with +12V linear regulator operating at 70°C ambient in enclosed control cabinets, electrolytic degradation causes regulator oscillation, lockup, and input/output module dropout.
- ✓LVDT feedback transducer connector corrosion and signal noise coupling — Bacher LVT series uses unshielded twisted pair in connector pins exposed to coolant aerosol and dust in Indian CNC and plastic injection shops. Copper pin oxidation increases contact resistance; lack of signal cable shielding couples 50 Hz mains noise and harmonic distortion, causing proportional valve chatter and runaway motion.
- ✓Real-time clock battery depletion and timestamp corruption in logic sequences — Bacher AUTO-Node and Legacy-Link modules embed a small CR2032 battery for RTC backup (typical 5-year life). When depleted, timestamp registers default to epoch 1970, causing production sequence logic to fail, timestamp-dependent interlocks to malfunction, and batch records to become untrustworthy in food, pharma, and chemical processing plants.

Frequently Asked Questions — BACHER Repairs
Do you repair Bacher equipment anywhere in India?+
Yes. Synchronics repairs the full Bacher product range — proportional controllers, servo drives, machine tool interfaces, automation nodes, and feedback transducers. We offer PAN India courier pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Kolkata, and all other industrial cities. All repairs are handled at our ISO 9001 facility in Vadodara, Gujarat. Average turnaround is 7-10 working days.
How do you diagnose Bacher proportional valve controller faults?+
Synchronics performs three-tier diagnostics: (1) Non-destructive electrical test — coil resistance, solenoid force measurement, feedback transducer calibration curve; (2) Functional validation on dedicated hydraulic test bench with dummy spool valve and pressure gauge; (3) Software/firmware verification using Bacher CAT diagnostic protocol and parameter readback. This approach isolates failures to coil, electronics, or spool/spool-sleeve wear.
What is the typical warranty on a Bacher repair from Synchronics?+
All Bacher repairs carry 12 months RTB (Return to Base) warranty and 6 months on-site warranty (call-out labour included in metro areas). We maintain spares inventory for common failure modes — coils, gate drivers, capacitor modules — so repeat failures are rare. Custom modules and proportional cards carry 18-month warranty if firmware updates are installed.
Can you service Bacher equipment that is no longer under OEM support?+
Absolutely. Synchronics specialises in legacy Bacher equipment — MTI-100, AUTO-Node 16, early SA-2000 series amplifiers. We maintain design documentation, source equivalent components where Bacher originals are obsolete, and reverse-engineer firmware for units with corrupted code. Indian textile mills, foundries, and small CNC job shops rely on us to keep 15-20 year old Bacher installations running.
How do I prevent Bacher servo amplifier and proportional controller failures in my factory?+
Synchronics recommends: (1) Install filtered power supplies and 3-phase EMC filters per IS/IEC 61800 to reduce harmonic distortion. (2) Use shielded twisted-pair cable with ferrite chokes on all signal lines. (3) Maintain cabinet temperature below 45°C with axial cooling fan. (4) Perform annual capacitor ESR testing on AUTO-Node units. (5) Request on-site commissioning and parameter audit every 3 years. We offer Bacher preventive maintenance contracts covering all these checks.
How do I send my BACHER 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 BACHER 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 BACHER 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 BACHER 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.
