E-M Product Lines We Repair
Our engineers are trained on the full E-M product range. Below are the major product families we service.
E-M Servo Amplifiers & Drives
Analog and digital servo amplifier modules for closed-loop motor control. Common repairs include output stage failures, feedback signal loss, gain calibration drift, and thermal protection faults in continuous-duty industrial applications.
E-M Encoder & Feedback Systems
Incremental and absolute position encoders with signal conditioning interfaces. Failures typically involve connector corrosion, signal line discontinuity, gray-code decoding errors, and SSI/CANopen module malfunctions in dusty textile and packaging environments.
E-M Stepper Motor Drivers
Microstepping and full-step driver modules for precision positioning in CNC and automation equipment. Repair issues include stuck phase outputs, MOSFET burnout, microstepping resolution loss, and enable/direction signal logic faults.
E-M Motion Control Modules (MCM)
Standalone motion controllers with analog velocity command and digital step/direction inputs. Common faults: ramp generator circuit failures, output limiting drift, analog reference circuit instability, and firmware corruption in legacy systems.
E-M Digital Position Monitors
Display and control units for real-time position feedback in production machinery. Repair challenges include LCD display failure, keypad contact resistance, RS232/RS485 communication loss, and non-volatile memory data corruption.

Common E-M Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in E-M equipment arriving at our workshop.
- ✓E-M servo amplifier output stage failure — MOSFET or IGBT output transistors fail due to transient voltage spikes during rapid load deceleration or insufficient gate drive capacitance. Common in unshielded installations near high-current switching equipment in Indian foundries and metalworking shops.
- ✓E-M encoder signal noise and intermittent feedback loss — Connector corrosion, twisted pair separation, or EMI ingress on unshielded signal lines in high-interference environments (textile looms, induction furnaces, welding bays). Encoder clock lines are particularly vulnerable in humid Indian mill conditions.
- ✓E-M stepper driver microstepping resolution degradation — Capacitor aging in the analog integrator circuit causes phase current waveform distortion. Also caused by MOSFET paralleling imbalance when multiple drivers are stacked. Manifests as jerky, lossy motion and reduced holding torque in precision CNC tables and pick-and-place machines.
- ✓E-M motion controller ramp generator oscillation and instability — Analog integrator RC network component drift or coupling capacitor high-frequency oscillation. Ramp output voltage becomes unstable, causing speed hunting and servo lag. Prevalent in 20-30 year old E-M units still in use in tier-2 Indian manufacturing.
- ✓E-M digital position monitor LCD failure and data loss — LCD segments blacken due to liquid crystal degradation or backlight LED failure after 10-15 years. Non-volatile memory (EEPROM) data corruption occurs from incomplete firmware writes during power dips or lightning transients in Indian mill environments with poor grid stability.
- ✓E-M encoder SSI/CANopen module protocol timeout and intermittent data — Firmware timeout logic triggers when bit rate drifts due to aging oscillator capacitors. CANopen PHY layer faults occur from mismatched termination resistors or biasing errors on multi-node networks. Common in retrofitted automation systems where encoder modules are replaced without network reconfiguration.

Frequently Asked Questions — E-M Repairs
Do you repair E-M equipment anywhere in India?+
Yes, absolutely. Synchronics repairs the complete E-M servo drive, encoder, stepper, and motion control product range. We offer door-to-door pickup from all major Indian cities — Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Indore, and beyond. All repairs are completed in our facility in Vadodara, Gujarat. Typical turnaround is 5-7 working days for standard repairs, and 3-5 days for emergency callouts.
Can you repair my old E-M servo amplifier or does it need replacement?+
Most E-M servo amplifiers can be repaired cost-effectively, even units 15-25 years old. We replace failed power transistors, recalibrate analog circuits, and repair connector damage. Repair cost is typically 30-50% of a new unit. We recommend replacement only if the amplifier has suffered catastrophic damage (burnt PCB, multiple component failures, or obsolete custom modules). Contact us with photos and the model number for a free diagnosis.
What E-M encoder problems can you fix, and how long does it take?+
We repair E-M encoder signal faults, connector corrosion, SSI/CANopen communication losses, and display/output module failures. Simple connector replacement takes 1-2 days. Signal integrity issues (shielding, termination, clock issues) typically take 3-4 days. Complete module replacement takes 2-3 days. Absolute encoders with memory corruption may require 4-5 days for firmware recovery and recalibration. We provide detailed test reports confirming output accuracy before dispatch.
Do you offer spare parts for E-M equipment or only repair services?+
Synchronics repairs E-M equipment as our primary service. We source genuine E-M spare parts through authorized German distributors for integration into repair jobs (connectors, capacitors, transistors, encoder heads). For obsolete or custom parts, we source compatible industrial-grade equivalents with full compatibility testing. We do not stock E-M parts as inventory for retail sale, but we can procure parts on demand for your repair.
How do I know if my E-M stepper driver needs repair or if the motor is faulty?+
Bring both the E-M stepper driver module and the stepper motor to Synchronics. We test the driver independently with a known-good motor and a reference load. We also test your motor on a known-good driver. This isolation test pinpoints whether the fault is in the driver (output stage, microstepping, logic) or the motor (winding, rotor, mechanical). We'll provide a written diagnosis and repair cost before proceeding. Most stepper failures are driver-side and repairable.
How do I send my E-M 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 E-M 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 E-M 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 E-M 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.
