EPSILON Equipment We Repair — By Category
EPSILON Product Lines We Repair
Our engineers are trained on the full EPSILON product range. Below are the major product families we service.
EPSILON Servo Amplifiers
High-performance servo amplifiers for brushless and brush DC motors. Common faults include IGBT module failure under thermal stress, encoder communication loss, and phase-current sensing circuit degradation in tropical Indian factory environments.
EPSILON Motion Controllers
Standalone and networked motion control units for multi-axis synchronization. Typical failures include firmware corruption, CAN/Ethernet port burnout from power surges, and stepper motor driver IC burnout in textile and packaging applications.
EPSILON Closed-Loop Stepper Drives
Integrated stepper motor drivers with real-time position feedback. Common issues include microstepping current imbalance, thermal runaway of power transistors, and loss of encoder signal in high-vibration environments.
EPSILON IO Modules and Interface Cards
Digital and analog input-output modules for EPSILON controller ecosystems. Repair involves relay contact corrosion, optocoupler failure from voltage spikes, and connector degradation in humid industrial conditions.
EPSILON Encoder and Feedback Interfaces
Incremental and absolute encoder signal conditioning boards for servo loop closure. Failures stem from cable shielding breakdown, differential receiver IC burnout, and resolver-to-digital converter accuracy loss.
Why Choose Synchronics for EPSILON Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on EPSILON equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common EPSILON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EPSILON equipment arriving at our workshop.
- ✓EPSILON servo amplifier power stage thermal shutdown — IGBT modules degrade under sustained peak current in tropical Indian climates. Heatsink fouling from lint and dust in textile mills accelerates thermal stress, triggering overcurrent protection.
- ✓EPSILON encoder communication loss - ERR_ENC_TIMEOUT — Long cable runs in noisy electrical environments (common in Indian paper mills and printing presses) cause differential signal degradation. Connector corrosion and ground loop formation break feedback continuity.
- ✓EPSILON motion controller CAN bus communication failure — Power surges from pump motor contactor switching and unshielded relay contacts inject common-mode noise onto CAN differential lines. CAN transceiver ICs fail from ESD and overvoltage stress typical in Indian industrial switchyards.
- ✓EPSILON stepper closed-loop drive microstepping current imbalance — Phase current sensing resistors drift and develop thermal hysteresis under sustained 2A+ phase current. DAC reference IC degradation and power supply ripple cause uneven coil excitation, resulting in step loss and vibration.
- ✓EPSILON amplifier DC bus overvoltage shutdown - FAULT_DCBUS_HIGH — Regenerative motor braking energy feedback during rapid deceleration exceeds bus voltage clamp rating. Worn diode bridges in dynamic braking circuits fail to dissipate energy. Common in hoist and packaging line servo applications.
- ✓EPSILON IO relay contacts sticking and failing to open — Arcing current from inductive solenoid loads (unmaintained coil suppression diodes) welds relay contacts. Humidity in monsoon-exposed control cabinets causes contact corrosion and oxide film formation in Indian packaging plants.

Frequently Asked Questions — EPSILON Repairs
Do you repair EPSILON equipment anywhere in India?+
Yes. Synchronics repairs the full EPSILON product range including servo amplifiers, motion controllers, stepper drives, and encoder interfaces. We offer PAN India door-to-door pickup service from major cities including Mumbai, Delhi, Pune, Bengaluru, Chennai, Hyderabad, Ahmedabad, Jaipur, and Kolkata. All repairs are performed at our central facility in Vadodara, Gujarat, with same-day diagnostic assessment for urgent breakdowns.
What is the typical turnaround time for EPSILON servo amplifier repair?+
Standard repair turnaround is 3-5 working days including incoming inspection, component-level diagnostics, repairs, and full-load testing on our servo test bench. For critical production line shutdowns, we offer expedited same-day diagnostic reports and next-day repair completion for EPSILON SA series amplifiers. Customers in Gujarat and neighboring states benefit from same-day return shipment.
Can you repair EPSILON closed-loop stepper drives with encoder calibration?+
Absolutely. EPSILON closed-loop stepper drives (CLS series) require precision encoder signal conditioning and microstepping current calibration. Our team uses a precision current source and encoder simulator to restore accurate step resolution and eliminate half-stepping vibration. We also verify load torque performance on our dynamometer-coupled motor test setup before returning repaired drives.
Do you stock replacement EPSILON modules and spare parts?+
Synchronics maintains a curated inventory of EPSILON servo amplifier modules, motion controller boards, encoder interface cards, and commonly replaced components. We source OEM parts through established Italian distributor relationships to guarantee authenticity. For urgent shortages, we perform sub-component level repairs (IGBT replacement, capacitor bank upgrades, connector restoration) within 24 hours.
How do you handle EPSILON fault codes like ERR_PHASE_LOSS or ERR_ENCODER_MISMATCH?+
EPSILON fault codes are logged in non-volatile memory and reflect specific subsystem failures. Our diagnostic protocol uses EPSILON's native encoder simulator, phase current injection test, and closed-loop servo loop analyzer to pinpoint the root cause. We then repair failed components (sensor interfaces, signal conditioning circuits, or firmware corruption) and clear fault codes after verification. Full test reports are provided with each repair.
How do I send my EPSILON 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 EPSILON 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 EPSILON 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 EPSILON 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.
