ACTEK Product Lines We Repair
Our engineers are trained on the full ACTEK product range. Below are the major product families we service.
ACTEK Motion Controllers (MC-Series)
Multi-axis stepper and servo motion control cards with step/direction and pulse-width interfaces. Common faults include encoder feedback loss, step pulse generation failure, and thermal shutdown due to inadequate heatsinking in high-frequency applications.
ACTEK Stepper Drivers (SD-Series)
Microstepping drivers for NEMA23/34/42 motors with built-in current limiting and position monitoring. Repair focus: MOSFETs shorting under transient load, phase coil winding insulation breakdown, and hall-sensor calibration errors.
ACTEK Servo Amplifiers (SA-Series)
Closed-loop servo drivers with encoder feedback, torque limiting, and CANopen/EtherCAT fieldbus support. Typical failures: capacitor bank ESR drift causing instability, IGBT gate-drive circuit faults, and servo loop calibration data corruption.
ACTEK Industrial PLCs (CP-Series)
Compact programmable controllers with analog/digital I/O, Modbus RTU/TCP, and relay output switching. Common issues: SD card corruption, real-time clock failure, and input isolation optocoupler degradation in humid/washdown environments.
ACTEK HMI Touchpanels (TP-Series)
7-10 inch resistive and capacitive touchscreen terminals with Ethernet and serial connectivity. Repair scope: LCD backlight LED failure, touchscreen controller IC faults, and firmware corruptions affecting communication with ACTEK motion systems.
ACTEK Fieldbus Gateways (FG-Series)
Protocol converters between CANopen, Modbus RTU, and Ethernet for legacy ACTEK system integration. Repair challenges: RS485 transceiver burnout from lightning surges, CAN termination resistor failures, and firmware version mismatches.

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 ACTEK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ACTEK equipment arriving at our workshop.
- ✓ACTEK stepper driver phase coil short circuit — Winding insulation breakdown due to moisture ingress or thermal cycling in MC-2404/SD-2206 drivers used in humid Indian textile mill environments. Typically manifests as persistent overcurrent trip despite motor disconnection.
- ✓ACTEK motion controller encoder feedback loss error — Loose or corroded encoder connector (M12 A-code) or shielding discontinuity in SA-3015/MC-4808 servo loops. Common in automotive assembly lines with frequent vibration and cable flexing.
- ✓ACTEK PLC Modbus RTU communication timeout — RS485 half-duplex transceiver IC failure (often SN65HVD11/MAX485 derivative) or termination resistor open in CP-220/CP-340 units operating in noisy pharmaceutical manufacturing environments.
- ✓ACTEK HMI touchpanel LCD backlight dimming or no display — LED string open circuit or PWM boost converter IC malfunction in TP-150E/TP-215 units exposed to power transients. Rare: aged LCD filter capacitor ESR increase reducing contrast.
- ✓ACTEK fieldbus gateway CAN bus arbitration loss — Dual CAN port collision logic failure in FG-Dual-CAN or corrupted bootloader in FG-CAN-RTU after power-cycle during firmware upload. Affects Indian food processing plants using ACTEK + third-party CANopen nodes.
- ✓ACTEK real-time clock (RTC) battery depletion causing timestamp loss — Coin-cell CR2032 exhaustion after 3-5 years in CP-550-Eth PLCs, or leaked battery electrolyte corroding PCB traces near RTC crystal oscillator in offline systems.

Frequently Asked Questions — ACTEK Repairs
Do you repair ACTEK equipment anywhere in India?+
Yes. Synchronics repairs the full ACTEK product range - motion controllers, stepper/servo drivers, industrial PLCs, HMI terminals, and fieldbus gateways. We offer PAN-India courier pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Nagpur, and all other industrial cities. All repairs are benchmarked and tested at our Vadodara, Gujarat facility with 48-72 hour turnaround.
What is ACTEK and why should I choose Synchronics for repairs?+
ACTEK is a Taiwan-based industrial automation OEM specializing in motion control, stepper/servo drivers, and factory automation PLCs widely used in Indian discrete manufacturing. Synchronics has certified expertise in ACTEK firmware, motion algorithms, encoder feedback loops, and fieldbus integration. Unlike generic repair shops, we maintain ACTEK reference designs, test benches with real motors/encoders, and provide full diagnostic reports with preventive upgrade recommendations specific to your application.
Can Synchronics repair ACTEK stepper drivers that won't move or throw overcurrent faults?+
Absolutely. ACTEK stepper driver faults (SD-2206, SD-3210, SD-4215) are among our core strengths. We perform coil continuity/insulation testing, MOSFET array verification under load simulation, current-sense circuit calibration, and full phase-current profiling. If the driver phase coils are shorted, we replace with OEM-specification magnet wire and re-calibrate microstepping resolution. We also test against your actual NEMA motor post-repair.
Does ACTEK motion controller firmware get corrupted, and can you restore it?+
Yes, ACTEK MC-Series and SA-Series firmware can corrupt due to power glitches, failed SD card, or bootloader damage. Synchronics has JTAG and serial programming capability for all ACTEK controllers. We perform full firmware extraction/backup, validate checksums, reload factory images, and recalibrate motion parameters (axis tuning, encoder scaling, velocity ramp limits) specific to your machine. Turnaround is typically 24-48 hours.
What certifications and warranties do ACTEK repairs carry?+
Synchronics provides 12-month parts replacement warranty on all ACTEK repairs, comprehensive test reports with waveform captures, and full technical documentation. Our engineers are factory-trained on ACTEK diagnostics. We also offer preventive maintenance contracts for high-utilization ACTEK systems in pharmaceutical and automotive plants, including periodic firmware updates and encoder calibration checks at your site.
How do I send my ACTEK 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 ACTEK 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 ACTEK 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 ACTEK 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.
