STEP AUTOMATION Equipment We Repair — By Category
STEP AUTOMATION Product Lines We Repair
Our engineers are trained on the full STEP AUTOMATION product range. Below are the major product families we service.
STEP Motion Controllers
STEP-branded stepper and servo motion control modules designed for multi-axis positioning and synchronization. Common failures include loss of step pulses, axis timeout errors, encoder communication faults, and firmware corruption after power surges.
STEP Programmable Logic Controllers
Compact PLC systems for industrial automation with Ethernet and serial I/O. Repair issues include memory corruption, real-time clock failures, I/O module burnout, and communication port failures in high-vibration textile and packaging environments.
STEP Stepper Drivers and Power Modules
Microstepping stepper drivers and integrated power modules for 2-phase and 3-phase stepper motors. Typical faults include MOSFETs burnout due to thermal stress, current sense circuit failures, and phase winding short circuits from moisture ingress.
STEP HMI Touch Panels
Industrial human-machine interface panels with 7-inch and 10-inch resistive/capacitive touchscreens for line control and monitoring. Failures include touchscreen unresponsiveness, display backlight degradation, SD card read errors, and Ethernet connectivity loss.
STEP Encoder Interfaces and I/O Modules
Multi-channel encoder signal conditioning cards and discrete I/O expansion modules for STEP automation systems. Common repair issues include differential line receiver IC failures, opto-coupler burnout, relay contact welding, and polarity-induced damage.

Common STEP AUTOMATION Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in STEP AUTOMATION equipment arriving at our workshop.
- ✓STEP Motion Controller axis timeout error — STEP MC series controllers lose synchronization with stepper motors due to missed step pulses, typically caused by loose encoder cable connectors, corrupted motion firmware, or noise-induced signal loss on long cable runs in noisy manufacturing floors common in Indian textile mills.
- ✓STEP PLC memory corruption and boot failure — Repeated power surges, uncontrolled shutdowns, and high-humidity environments in Indian food and pharmaceutical processing plants cause EEPROM corruption in STEP PLC systems, preventing normal boot sequence and halting production lines.
- ✓STEP stepper driver MOSFET burnout and phase short — Inadequate heatsinking and thermal stress in summer operations, combined with misaligned motor windings and accidental phase-to-phase shorts, cause catastrophic MOSFET failure in STEP SD series drivers used in high-speed packaging lines.
- ✓STEP HMI touchscreen unresponsiveness and display failure — Industrial dust accumulation, vibration-induced connector loosening, and power supply voltage fluctuations common in Indian manufacturing plants cause display backlight failure, touch controller IC malfunction, and SD card read errors in STEP HMI panels.
- ✓STEP encoder interface differential line receiver failure — Long cable runs from encoders to STEP ENC-4CH or ENC-8CH modules, combined with unshielded wiring and proximity to power cables, introduce noise that destroys RS422 line receiver ICs and causes false motion counts.
- ✓STEP I/O relay contact welding and loss of discrete output — High inrush current from solenoids and pneumatic valve coils, insufficient contact protection, and thermal cycling in Indian manufacturing facilities cause relay contact fusion in STEP IO-Module 32 relay expansions, creating stuck outputs.

Frequently Asked Questions — STEP AUTOMATION Repairs
Do you repair STEP Automation equipment anywhere in India?+
Yes. Synchronics repairs the full STEP Automation product range — motion controllers, stepper drivers, PLCs, HMI panels, and I/O modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other industrial cities. Repairs are completed at our factory in Vadodara, Gujarat with guaranteed turnaround and customer communication.
What STEP Automation firmware versions and motion control protocols do you support?+
Synchronics supports all STEP Automation firmware versions from 2010 onward, including legacy versions used in older MC-2 and MC-3 controllers. We are proficient in STEP proprietary motion command protocols, Modbus RTU/TCP communication stacks, pulse-direction servo control, and closed-loop step accuracy verification. Our engineers maintain updated copies of STEP documentation and diagnostic software licensed from the manufacturer.
Can you repair STEP motion controllers with corrupted or missing firmware?+
Yes. Synchronics performs EEPROM extraction, firmware re-flash using STEP programming tools, and bootloader recovery for all STEP motion controller models. If original firmware is unavailable, we source it from STEP Automation or recover it from customer backup. We test every repaired controller under simulated multi-axis load before return to ensure motion accuracy and response time meet specifications.
How do you troubleshoot STEP HMI display and touchscreen faults?+
Our process includes component-level backlight power supply testing, touchscreen IC diagnostics using capacitive response analysis, and SD card file system repair. We replace failed display modules, reprogram touch calibration data, and upgrade power supply regulators to handle Indian voltage fluctuations. Each HMI is functionally tested with customer application software before shipment.
What is your typical turnaround time for STEP Automation repair?+
Standard STEP repairs complete in 7-10 business days including diagnostics, parts sourcing, repair, testing, and documentation. Urgent repairs with expedited parts availability complete in 3-5 days. Critical downtime situations are prioritized. All work includes 6-month warranty on replaced components and includes diagnostic reports detailing root cause and preventive maintenance recommendations.
How do I send my STEP AUTOMATION 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 STEP AUTOMATION 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 STEP AUTOMATION 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 STEP AUTOMATION 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.
