APEX Product Lines We Repair
Our engineers are trained on the full APEX product range. Below are the major product families we service.
APEX Servo Drives
High-torque servo motor drivers for precision positioning and velocity control in CNC machines, textile looms, and packaging equipment. Common faults include encoder communication loss, thermal shutdown, and phase loss due to power supply instability in Indian industrial environments.
APEX Motion Controllers
Multi-axis motion control platforms for coordinated machine operation. Repair issues include EEPROM corruption, I/O module failures, and communication timeouts when interfacing with legacy plant networks.
APEX Stepper Drivers
Microstepping driver circuits for stepper motors in printing, labeling, and coordinate measuring machines. Prone to MOSFET burnout, over-temperature lockout, and step-pulse synchronization errors under load.
APEX Encoder Interface Modules
Closed-loop feedback conditioning for rotary encoders and linear transducers. Common failures include analog signal conditioning circuit faults, quadrature decoding errors, and connector pin corrosion in humid Indian factory floors.
APEX Programmable Logic Gateways
Industrial Ethernet and fieldbus converters for APEX devices. Prone to network stack corruption, DHCP timeout loops, and Modbus/TCP communication hangs in factories with electrical noise.

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 APEX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in APEX equipment arriving at our workshop.
- ✓Encoder communication loss and feedback timeout — APEX servo drives lose quadrature signal from rotary encoders due to cable shielding degradation, connector corrosion in humid/oily factory environments, or firmware timing synchronization drift. This is especially common in Indian textile mills and automotive assembly lines with poor cable management.
- ✓Thermal shutdown and repeated over-temperature errors — APEX servo driver MOSFETs and output stages overheat due to poor ventilation in control cabinets, inadequate heatsink contact, or sustained over-current from undersized power supplies common in retrofit installations across Indian factories.
- ✓Phase loss detection and single-phase mode lockout — APEX drives detect missing AC mains phase due to loose contactors, worn soft-starters, or neutral grounding faults prevalent in Indian industrial power distribution. Drives enter protective shutdown mode refusing manual restart.
- ✓EEPROM parameter corruption and factory reset loops — APEX motion controller EEPROM sectors corrupt due to power supply surges, ESD static discharge during commissioning, or voltage sag during UPS battery transitions common in Indian plants with unstable grid power.
- ✓Step-pulse synchronization loss and missed step counts — APEX stepper drivers lose pulse timing alignment due to EMI from adjacent VFDs or servo drives, loose input signal connectors, or sluggish pulse conditioning circuits when high-speed pulse rates exceed driver bandwidth in Indian CNC retrofit projects.
- ✓Network gateway communication timeouts and fieldbus hangs — APEX Ethernet gateway firmware enters infinite wait loops due to IP address conflicts, DHCP server unavailability, or Modbus TCP message fragmentation when interfacing legacy Indian factory PLCs over noisy industrial networks.

Frequently Asked Questions — APEX Repairs
Do you repair APEX equipment anywhere in India?+
Yes. Synchronics repairs all APEX product lines — servo drives, motion controllers, stepper drivers, encoder interfaces, and network gateways. We offer PAN-India door-step pickup and return from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all major industrial cities. All repairs are handled in our main facility in Vadodara, Gujarat with 24-48 hour turnaround for standard faults.
Can you repair APEX servo drives with encoder feedback errors?+
Yes, absolutely. APEX servo encoder communication faults are among our most common repairs. We diagnose encoder signal integrity, test quadrature phase alignment, replace corroded connectors, and validate closed-loop performance before return. Many Indian textile mills and CNC shops send us APEX drives with encoder timeout errors — we have the test equipment and firmware tools to restore reliable feedback operation.
What is the typical repair cost and turnaround for APEX motion controller EEPROM corruption?+
APEX motion controller EEPROM corruption repair typically costs 4,500-8,500 INR depending on parameter recovery complexity and firmware version. Turnaround is 3-4 working days including EEPROM data recovery, parameter reconstruction, firmware update, and functional testing. Synchronics provides a one-year warranty on repaired controllers and supplies backup parameter documentation.
Do you offer APEX drive firmware updates and parameter backup services?+
Yes. Beyond repair, Synchronics performs APEX firmware version updates to latest stable releases, extracting and backing up your motion parameters before any firmware change. We also provide on-site commissioning support for repaired APEX drives including encoder calibration, current limiting setup, and velocity ramp tuning specific to your motor and load.
How do you handle APEX stepper driver MOSFET failures and thermal shutdown?+
APEX stepper driver MOSFET burnout is typically caused by supply surges or sustained over-current. Synchronics performs component-level repair replacing output stage MOSFETs, verifying heatsink assembly, and stress-testing at 125% rated current before return. We also audit your power supply adequacy and recommend TVS diodes or supply filtering to prevent recurrence in your Indian facility.
How do I send my APEX 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 APEX 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 APEX 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 APEX 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.
