ACCOS Product Lines We Repair
Our engineers are trained on the full ACCOS product range. Below are the major product families we service.
ACC-PLC Series
Modular programmable logic controllers with integrated motion control and safety functions. Common issues include firmware corruption, memory module failures, and Ethernet port malfunctions after power surges or industrial EMI exposure.
ACCOS Motion Control Module (MCM)
Servo and stepper motor control units with analog/digital I/O and CANopen connectivity. Typical faults include PWM driver IC degradation, encoder signal loss, and parameter corruption in non-volatile memory.
ACCOS HMI Touch Panel Series
Industrial touchscreen terminals for real-time process monitoring and control. Common repair issues: capacitive touch sensor failures, LCD backlight degradation, SD card corruption, and serial communication interface wear.
ACCOS I/O Terminal Blocks
Modular digital and analog input/output interface cards with Phoenix-style screw terminals. Failures typically stem from relay coil burnout, optocoupler degradation, and terminal corrosion in humid/wet industrial environments.
ACCOS Fieldbus Gateway (EtherCAT/PROFIBUS)
Industrial communication interface modules bridging legacy PROFIBUS networks with modern EtherCAT systems. Repair challenges include PHY layer IC failures, transformer burnout, and protocol stack software corruption.

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 ACCOS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ACCOS equipment arriving at our workshop.
- ✓ACC-PLC firmware corruption causing boot loop — Unexpected power loss during OTA firmware update, or corrupted program storage after industrial EMI spike. ACCOS systems store bootstrap code in flash memory vulnerable to power transients.
- ✓MCM servo driver heat sink thermal runaway — Inadequate cooling in high-ambient-temperature environments (>45°C), combined with continuous full-load motor operation. ACCOS PWM driver ICs generate significant heat and lack active cooling in standard configurations.
- ✓HMI touchscreen no response to finger input — Capacitive touch controller IC failure or degradation of touch sensor lines due to moisture ingress. ACCOS HMI panels use single-layer PCB touch overlay susceptible to humidity in non-sealed enclosures.
- ✓PROFIBUS gateway intermittent frame errors and node dropout — Transformer coupling capacitor leakage on the PROFIBUS line isolation stage, or RS-485 termination resistor network failure. High-noise industrial environments degrade ACCOS isolation circuitry over time.
- ✓ACC-PLC memory module not recognized or program loss — SDRAM or EEPROM module loose socket contact, battery backup circuit failure, or DRAM refresh circuit malfunction. ACCOS uses standard SO-DIMM modules vulnerable to vibration and thermal cycling in harsh environments.
- ✓Analog input channel reading oscillates or drifts wildly — Op-amp input stage degradation, reference voltage supply ripple, or shielded cable connection corrosion in the I/O terminal block. ACCOS analog front-end circuits use precision components sensitive to moisture and EMI.

Frequently Asked Questions — ACCOS Repairs
Do you repair ACCOS equipment anywhere in India?+
Yes, Synchronics repairs the full ACCOS control and automation product range across India. We offer PAN India door pickup service from major cities—Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all industrial hubs. All repairs are processed at our factory facility in Vadodara, Gujarat, where our 180+ engineers maintain ACCOS-certified equipment, test benches, and software libraries. Turnaround time is typically 7-14 working days depending on fault complexity.
What is the typical turnaround time for ACC-PLC firmware recovery?+
ACCOS firmware corruption repairs usually take 2-3 working days. Our team performs JTAG boundary scan diagnostics, secures your original program code via EEPROM readback, re-flashes factory bootloader, and validates checksum integrity. We then burn-test the PLC under simulated industrial load for 24 hours before shipment. Rush turnaround (24-48 hours) available for critical production lines at premium rates.
Can Synchronics recover my lost ACC-PLC program code?+
In many cases, yes. If your program was stored in EEPROM (non-volatile memory), we can read the original code via JTAG/ISP interfaces before repairing the CPU board. We then restore it to the repaired unit. However, if the EEPROM is physically damaged, recovery is not possible. We strongly recommend customers maintain offline program backups and SD card exports. Synchronics can also help design backup strategies specific to your ACCOS configuration.
Do you handle ACCOS HMI touchscreen repairs in Vadodara or do I need to send it to Germany?+
All ACCOS HMI repairs are handled in-house at Synchronics Vadodara. We replace touchscreen controller ICs, recalibrate the capacitive touch matrix, repair LCD backlighting issues, and reprogram SD card firmware locally. Unlike sending equipment to Germany (8-12 weeks + shipping costs), our facility delivers repairs in 5-7 working days. We maintain factory-grade ACCOS HMI spare parts inventory for models HMI-Panel-7, HMI-Panel-10, and HMI-Panel-15-Pro.
What warranty do you provide on ACCOS repairs?+
All Synchronics ACCOS repairs carry a 12-month comprehensive warranty covering parts and labor. We issue detailed test reports with fault logs, repair methodology, and functional verification results. Should any repaired unit fail within warranty, we offer free re-repair or replacement (subject to inspection). For mission-critical equipment, we offer extended 24-month warranty at 15% of repair cost. All warranty claims are processed within 48 hours from Vadodara.
How do I send my ACCOS 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 ACCOS 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 ACCOS 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 ACCOS 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.
