FSM Product Lines We Repair
Our engineers are trained on the full FSM product range. Below are the major product families we service.
FSMAXIAL Grinding & Polishing Spindle Systems
High-speed spindle control electronics for precision grinding and polishing operations. Common issues include spindle bearing wear feedback errors, encoder signal loss, servo amplifier failures, and thermal protection circuit faults affecting finish quality.
FSM RENOVA Automated Finishing Centres
Integrated finishing systems combining CNC motion control, spindle regulation, and material handling. Repair focus on main servo drives, proximity sensors, tool wear monitoring electronics, and process parameter memory chip failures.
FSM Deburring & Edge Finishing Controls
Specialized PLC and motion controller electronics for automated deburring operations. Typical faults include analogue output module failures affecting feed rate precision, pressure sensor signal corruption, and limit switch circuit malfunctions.
FSM Spindle Power Amplifiers & Drives
Dedicated power electronics managing 3-phase spindle motors from 2 kW to 30 kW. Failure modes include IGBT module breakdown, capacitor degradation, spindle current feedback instability, and thermal sensor disconnection.
FSM HMI Touch Interfaces & Monitoring Panels
7-inch to 15-inch operator interfaces for process control and real-time system diagnostics. Common failures: capacitive touch sensor degradation, memory corruption affecting recipe storage, communication interface errors, and backlight LED failure.
FSM Encoder & Position Feedback Systems
Absolute and incremental encoders providing spindle speed and tool position feedback. Repair addresses cable shielding damage, connector oxidation, internal disc wear, and signal conditioning circuit failures causing grinding quality loss.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common FSM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in FSM equipment arriving at our workshop.
- ✓FSM spindle encoder signal dropout intermittent — Humidity ingress into optical encoder housing or worn slip rings in rotary coupling cause intermittent signal loss, triggering spindle overspeed faults and production stoppages. Common in high-vibration grinding operations.
- ✓FSM spindle amplifier IGBT thermal shutdown loop — Aged electrolytic capacitors in FSP power amplifiers develop high ESR, reducing charge storage and triggering false over-temperature shutdowns even at normal operating loads. Affects spindle motor acceleration performance.
- ✓FSM HMI touchscreen recipe data corruption loss — Power interruptions or EEPROM flash wear cause stored finishing program parameters to become inaccessible, forcing manual reconfiguration. Critical for multi-operation grinding sequences.
- ✓FSM servo motor feedback current unstable fluctuation — Connector pin corrosion in motor feedback cable or internal Hall-effect sensor degradation in RENOVA servo drives causes noisy current feedback, reducing feed rate precision and finish consistency.
- ✓FSM deburring control pressure sensor readings invalid — Crystalline salt deposits from coolant misting corrode piezoelectric sensor diaphragms in DBCONTROL circuits, causing feed pressure to become unmeasurable and automated deburring sequences to fail.
- ✓FSM communication interface Ethernet timeout fault codes — Inadequate cable shielding in industrial environments or network switch port saturation causes RENOVA HMI to lose contact with spindle controller, triggering E-COMM error codes and production halt.

Frequently Asked Questions — FSM Repairs
Do you repair FSM equipment anywhere in India?+
Yes. Synchronics repairs the complete FSM product range — spindle drives, servo amplifiers, HMI touchscreens, encoders, and RENOVA finishing system electronics. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, and all other cities. Repairs completed in our Vadodara facility with 30-day comprehensive warranty.
What FSM spindle motor repairs can Synchronics handle?+
Synchronics repairs FSM spindle amplifiers (2 kW to 30 kW), replaces burnt IGBT modules, restores capacitor banks, recalibrates thermal sensor circuits, and tests spindle ramp profiles on dedicated motor test bench. We also diagnose encoder signal quality issues causing spindle regulation faults in FSMAXIAL and RENOVA systems across Indian manufacturing plants.
How long does FSM HMI touchscreen repair take?+
HMI flash memory recovery typically takes 5-7 working days depending on data corruption severity. Touchscreen display replacement and capacitive sensor restoration take 3-4 days. Synchronics validates all recovered or reprogrammed recipes against your original FSM parameter database before dispatch to ensure seamless production restart.
Can you repair FSM RENOVA grinding system communication errors?+
Yes. Synchronics diagnoses RENOVA Ethernet and serial communication faults, replaces corroded connectors, installs industrial-grade shielded cabling, configures network switches for real-time traffic priority, and validates spindle-to-controller latency meets FSM specification. We serve precision finishing plants across Gujarat, Maharashtra, and Tamil Nadu requiring zero-downtime RENOVA restoration.
What warranty do you provide on FSM repairs?+
Synchronics offers 30-day comprehensive warranty on all FSM repairs covering parts and labour. Extended 12-month warranty available for spindle amplifiers and servo drives. All repairs backed by certificate of compliance with FSM technical specifications and tested performance validation on our industrial test equipment.
How do I send my FSM 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 FSM 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 FSM 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 FSM 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.
