ROCON Equipment We Repair — By Category
ROCON Product Lines We Repair
Our engineers are trained on the full ROCON product range. Below are the major product families we service.
ROCON Compact Servo Drives
Miniaturised servo amplifiers for stepper and BLDC motors with integrated encoder interfaces and USB/CANopen connectivity. Common faults include encoder cable failures, thermal sensor malfunctions, and firmware corruption from power surges.
ROCON Multi-Axis Motion Controllers
Standalone motion controllers supporting up to 8 axes with step-direction or analog command interfaces. Typical failures involve SD card corruption, FPGA timing issues, and I/O relay contact degradation in high-humidity Indian factory environments.
ROCON Stepper Motor Drivers
Full-step, half-step, and microstepping drivers with integrated limiters and soft-start logic. Repair focus includes MOSFETs thermal runaway, gate driver failures, and phase loss detection circuit malfunctions.
ROCON Encoder Interface Modules
SSI, BiSS, and EnDat encoder signal conditioning units with galvanic isolation and differential buffering. Common issues include capacitor failures, isolation barrier degradation, and frequency response instability at high encoder frequencies.
ROCON CANopen Node Modules
Embedded CAN transceiver modules with protocol stack memory and node ID configuration storage. Repair issues centre on CAN PHY transceiver shorts, EEPROM corruption, and termination resistor network failures.
ROCON Real-Time Kernel Boards
Embedded Linux and VxWorks runtime platforms for custom motion algorithms with dual Ethernet and RS-485 connectivity. Common faults involve Flash memory degradation, RAM module failures, and real-time clock drift after power cycling.

Common ROCON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ROCON equipment arriving at our workshop.
- ✓Encoder cable intermittent open circuit faults — ROCON servo drives use differential encoder inputs sensitive to cable flexing and vibration. In Indian textile mills and packaging lines, repetitive motion causes micro-fractures in shielded twisted pairs, leading to encoder signal dropouts and position loss errors.
- ✓Thermal sensor open or shorted thermistor — ROCON compact servo drives mount NTC thermistors directly on power stage heatsinks. In dusty Indian manufacturing environments and when cooling fans fail, the thermistor connection corrodes or separates, disabling thermal shutdown protection.
- ✓MOSFET gate driver IC failure with phase loss — ROCON stepper drivers use IR2110 or similar high-side gate drivers. In automotive assembly and CNC machining shops prone to electrical noise, incorrect drive pulse timing or parasitic oscillation damages the gate driver IC, causing single-phase shorts to ground.
- ✓CANopen protocol stack memory corruption — ROCON CAN modules store node configuration and firmware in on-board EEPROM. Power transients, incorrect shutdown procedures, or UV exposure during troubleshooting can corrupt the CAN parameter table, causing bus arbitration failures and loss of communication.
- ✓Firmware corruption due to failed bootloader update — ROCON multi-axis controllers use flash memory divided between bootloader and application firmware. Interrupted USB or Ethernet updates, power loss during programming, or incompatible firmware versions can brick the controller, leaving it unresponsive to commands.
- ✓Real-time clock drift and timestamp synchronisation loss — ROCON RTK boards use coin-cell-backed RTC modules. In Indian facilities without temperature-controlled server rooms, thermal cycling and battery voltage droop cause RTC register corruption, leading to incorrect event logging and encoder timestamp mismatches.

Frequently Asked Questions — ROCON Repairs
Do you repair ROCON equipment anywhere in India?+
Yes. Synchronics repairs the complete ROCON servo drive, motion controller, and encoder module product range across all of India. We offer door-to-door pickup service from major cities including Mumbai, Delhi, Bangalore, Pune, Hyderabad, Chennai, Ahmedabad, and Kolkata. Repairs are performed at our Vadodara facility and units are dispatched back within 7-10 working days. We maintain ROCON spare parts inventory and provide genuine replacement components.
What is your experience with ROCON servo drives in Indian manufacturing?+
Synchronics has repaired ROCON compact servo drives and stepper drivers since 2008 across textile mills, automotive component suppliers, and packaging machinery OEMs in Gujarat and Maharashtra. We have repaired over 400 ROCON motion control units, with specialisation in encoder interface faults, thermal runaway issues, and CANopen communication failures. Our engineers have attended ROCON factory training and maintain technical documentation for all product generations.
Can you recover data from corrupted ROCON controller firmware?+
Yes. If your ROCON multi-axis motion controller or RTK board has corrupted firmware, Synchronics uses JTAG or serial programming interfaces to read the flash memory, extract any readable configuration data, and reload the correct factory firmware. We maintain a firmware archive for ROCON hardware revisions dating back to 2010. Recovery success depends on whether the bootloader is still intact; we assess recoverability during intake inspection.
Do ROCON servo drives work with third-party encoders?+
ROCON compact servo drives support SSI, BiSS, and EnDat absolute encoders, as well as incremental HTL encoders. However, encoder signal conditioning and cable shielding are critical. We recommend using ROCON-approved encoder cable lengths (typically under 10 metres) and maintaining 120-ohm termination resistance. Synchronics can advise on compatible third-party encoders and validate signal integrity testing if you are considering encoder substitution on existing machinery.
What is the typical repair cost for ROCON stepper driver failures in Indian factories?+
Repair costs for ROCON stepper drivers range from INR 4,500 to INR 12,000 depending on the fault. Gate driver IC replacement is typically INR 5,000-7,000 including labour. MOSFET stage replacement is INR 8,000-12,000. We provide free intake diagnosis and quote repair cost before proceeding. For multi-axis controllers with firmware corruption, costs are INR 6,000-15,000 depending on recovery complexity. We offer 12-month warranty on all repairs.
How do I send my ROCON 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 ROCON 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 ROCON 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 ROCON 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.
