ELECTRO-NUMERICS Product Lines We Repair
Our engineers are trained on the full ELECTRO-NUMERICS product range. Below are the major product families we service.
EN-Series Numerical Controllers
Standalone CNC control units managing multi-axis machine tool motion, feed rates, and tool path execution. Common failures include parameter corruption, axis miscalibration, and encoder signal loss leading to position errors and machine lockups.
Servo Amplifier Modules
Single and dual-axis servo drive modules for spindle speed regulation and precision feed axis control. Failures typically manifest as thermal shutdown, servo loop instability, and loss of torque response during heavy cutting operations.
Spindle Drive Units
Dedicated AC spindle drivers providing variable frequency output for CNC spindle motors. Common faults include capacitor aging, phase imbalance detection, and over-speed trip conditions that halt production.
Motion Control Processor Boards
Core processing and timing boards handling interpolation, servo loop closure, and I/O management. Repairs address EEPROM failures, crystal oscillator faults, and daughter board connector corrosion issues.
Encoder Interface Modules
Signal conditioning and counting boards for incremental and absolute position feedback from machine encoders. Typical failures include optocoupler degradation and differential line receiver damage causing position jitter.

Common ELECTRO-NUMERICS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELECTRO-NUMERICS equipment arriving at our workshop.
- ✓Axis position drift and servo error accumulation — Electro-Numerics encoders suffer intermittent signal dropout due to cable shielding degradation or connector oxidation. The servo loop cannot maintain closed-loop feedback, causing the axis to drift and triggering servo-error alarms after extended machine runtime.
- ✓Spindle over-speed trip during rapid acceleration — Electro-Numerics spindle drive modules contain aging filter capacitors that degrade under thermal stress in Indian workshop environments. Weakened voltage regulation causes speed feedback instability, falsely triggering over-speed protection circuits.
- ✓Parameter memory loss and startup boot failure — Electro-Numerics controllers use older EEPROM technology susceptible to bit-flip corruption from thermal cycling and power surges. Parameter loss causes the controller to hang during initialization, displaying E-001 or E-002 error codes.
- ✓Intermittent axis lock-up during programmed moves — Electro-Numerics motion controller boards experience timing violations caused by failing crystal oscillators or corrupted interpolation firmware. The servo loop fails to update step/direction commands, halting mid-cycle.
- ✓Thermal shutdown and servo amplifier derating — Electro-Numerics servo amplifier modules accumulate dust and thermal paste degradation on heat sinks over years of operation in Indian manufacturing floors. Junction temperature sensors falsely trigger cutback or shutdown, reducing machine capability.
- ✓Loss of feed rate synchronization between multiple axes — Electro-Numerics controllers with dual or quad-axis configurations suffer clock skew when daughter boards develop cracked solder joints or timing line failures. Axis synchronization errors cause taper cutting and profile distortion.

Frequently Asked Questions — ELECTRO-NUMERICS Repairs
Do you repair Electro-Numerics equipment anywhere in India?+
Yes. Synchronics repairs the complete Electro-Numerics product range including numerical controllers, servo amplifiers, spindle drives, and motion processor boards across all model generations. We offer PAN-India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Chandigarh, and all other major cities. All repairs are handled at our state-of-the-art facility in Vadodara, Gujarat, with typical 48-72 hour turnaround.
What should I do if my Electro-Numerics controller displays E-001 error on startup?+
E-001 indicates EEPROM parameter checksum failure — a common issue in older Electro-Numerics controllers. Do not power-cycle repeatedly as this may cause further corruption. Contact Synchronics immediately. We will read your EEPROM content, restore valid parameters matched to your specific machine model and tooling configuration, and install surge protection to prevent recurrence. Most E-001 repairs complete within 48 hours.
Can Synchronics repair Electro-Numerics servo amplifiers, or do I need to buy new?+
Synchronics completely repairs Electro-Numerics servo amplifier modules SA-50, SA-100, SA-200, and SA-300 series. Common repairs include capacitor replacement, thermal management restoration, and servo loop gain re-tuning. New modules cost 3-4x more than our repair service. We stand behind every repair with a 12-month warranty, making servo module repair far more cost-effective than replacement for Indian job shops and manufacturing units.
How do I know if my Electro-Numerics spindle drive needs repair?+
Signs of spindle drive failure include sudden over-speed trips, inability to reach programmed RPM, thermal alarms without heavy load, and audible hum during spindle ramp-up. Electro-Numerics spindle drivers typically fail due to capacitor aging in hot Indian workshops. Bring the drive to Synchronics for free bench diagnostics. We test actual output frequency, voltage regulation, and thermal stability under load to determine if repair is possible.
Does Synchronics offer on-site support for Electro-Numerics machine commissioning?+
Yes. After repair, Synchronics can arrange on-site re-installation and functional commissioning of your Electro-Numerics controller or drive system at your facility in India. Our field engineers perform axis calibration, parameter verification, and test runs to confirm your machine returns to full operating specification. Additional charges apply. Contact our technical team in Vadodara for on-site service availability.
How do I send my ELECTRO-NUMERICS 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 ELECTRO-NUMERICS 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 ELECTRO-NUMERICS 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 ELECTRO-NUMERICS 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.
