STOGRA Equipment We Repair — By Category
STOGRA Product Lines We Repair
Our engineers are trained on the full STOGRA product range. Below are the major product families we service.
STOGRA Stepper Motor Drives
Microstepping stepper motor controllers for CNC machinery and precision positioning systems. Common issues include loss of stepper position, phase winding shorts, and encoder feedback errors in closed-loop variants.
STOGRA Servo Motion Controllers
Integrated servo axis controllers for multi-axis motion applications. Typical faults involve resolver feedback loss, MOSFET gate driver failures, and parameter memory corruption.
STOGRA EtherCAT Motion Interfaces
Industrial Ethernet motion control nodes for networked automation systems. Repair challenges include PHY layer failures, timing synchronization loss, and firmware update corruption.
STOGRA Power Supply Modules
Regulated DC supplies for stepper and servo systems, typically 24V to 48V outputs. Common failures are bulk capacitor aging, rectifier bridge shorts, and thermal shutdown circuit malfunction.
Why Choose Synchronics for STOGRA 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 STOGRA 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 STOGRA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in STOGRA equipment arriving at our workshop.
- ✓Stepper motor stalling or missed step pulses — STOGRA drives experience phase winding shorts or current sense resistor opens due to age or thermal stress, preventing proper current control to motor coils. This is especially common in textile mill looms and older CNC retrofits.
- ✓Loss of encoder feedback signal — STOGRA closed-loop stepper variants fail when encoder connectors corrode (common in humid Indian factories) or resolver winding insulation breaks down due to vibration-induced fatigue.
- ✓Drive not responding to command interface — STOGRA motion controllers suffer from microcontroller EEPROM corruption, especially after power surges common in Indian industrial zones, or failed SPI communication lines to daughter boards.
- ✓Thermal shutdown and overtemp protection cycling — STOGRA power stages overheat due to electrolytic capacitor drying (reducing ripple filtering) or heatsink mounting compound degradation, causing thermistor false triggers under normal load.
- ✓Erratic axis motion or intermittent direction reversal — STOGRA multi-axis controllers exhibit logic glitches when direction latch flip-flops fail or command signal transition timing shifts due to aging CMOS logic buffers.
- ✓Network timeout errors on EtherCAT modules — STOGRA ECM network interfaces drop frames when Ethernet transformer coupling caps fail or PHY layer crystal oscillator drifts, breaking EtherCAT frame synchronization.

Frequently Asked Questions — STOGRA Repairs
Do you repair STOGRA equipment anywhere in India?+
Yes. Synchronics repairs the complete STOGRA product range — stepper drives, servo controllers, EtherCAT motion modules, and power supplies. We offer PAN-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all tier-2 cities. Repairs are centralized in our Vadodara, Gujarat facility. Turnaround is typically 5-7 working days for standard faults.
How do I know if my STOGRA stepper drive has failed?+
Common signs include CNC axis not moving despite valid step commands, LED indicators on the drive not lighting, stepper motor stuttering or vibrating without smooth rotation, and repeated thermal shutdown. Some failures show 'Err' or 'OVT' codes on indicator displays. Synchronics offers free fault diagnosis — send the unit or describe symptoms and we'll advise next steps with no obligation.
Can STOGRA drives be repaired or must they be replaced?+
Most STOGRA faults are repairable. We successfully repair 88% of STOGRA units we receive, including complex multi-axis controllers and EtherCAT variants. Board-level component replacement, firmware restoration, and connector recertification address 95% of failure modes. Replacement is only recommended if the drive is extremely old (pre-2000), physically damaged, or repair cost exceeds 60% of new unit cost.
What makes STOGRA different from other stepper drive brands?+
STOGRA drives are precision-engineered for high-reliability environments — they feature robust resolver feedback integration, superior thermal stability, and excellent electrical noise immunity. This makes them popular in Indian textile mills and aerospace-grade CNC centers. However, their proprietary firmware and specialized resolver interfaces require expert technicians to repair correctly. Synchronics has invested in STOGRA-specific test equipment and component libraries to handle these complexities reliably.
Do you offer spare STOGRA components or modules?+
Yes. We stock common STOGRA replacement parts including stepper motor connectors (M23 Deutsch), encoder cables, filter capacitors rated for STOGRA power modules, and resolver interface PCB assemblies. For complete drive units, we source authentic STOGRA refurbished drives. We do not recommend third-party clones — they lack thermal and noise performance specs critical for Indian factory environments. Ask our sales team for availability and lead times on specific components.
How do I send my STOGRA 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 STOGRA 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 STOGRA 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 STOGRA 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.
