About Fastech

Conventional drive technology usually forces a compromise: easy handling or true precision — rarely both. FASTECH has specialized in solving exactly this problem for over two decades: closed-loop stepping systems, combining the reliability of a stepper motor with the precision of a servo drive — without either one's weaknesses.

Conventional drive technology usually forces you into a compromise:

• Open-loop stepper motors are simple and inexpensive, but can lose steps under load and, for safety reasons, use only part of the available torque.
• Servo motors provide position feedback, but require elaborate gain tuning and tend to oscillate disruptively during positioning ("hunting").

FASTECH's closed-loop stepping technology solves both problems: a high-resolution encoder continuously monitors the motor position and automatically corrects deviations — for example after a shock or an external force. The result: reliable positioning without step loss, full use of the available torque, and a stable end position without overshoot — all without any need for prior calibration.

• Encoder feedback updated every 25 µs
• High-precision encoder with up to 32,000 pulses per revolution
• Full use of rated torque (open-loop drives are limited to roughly 50% due to the risk of step loss)
• Approx. 30% torque increase across the entire speed range via an internal DC-DC boost converter and run current up to 150%
• Load-dependent current control for stable high-speed operation
• 32-bit DSP control for fast, precise motion calculation
• Compatible with common field networks: EtherCAT, PROFINET/PROFIdrive, standard Ethernet, CC-Link IE TSN, Modbus-RTU (Modbus-TCP reportedly in preparation by the manufacturer)
• Particularly well suited to low mechanical stiffness (e.g. belt drives), where conventional servo systems would need additional inertia matching

FASTECH Co., Ltd. was founded in 2001 in Bucheon, South Korea, and has specialized in closed-loop stepping systems ever since. The manufacturer describes its own approach through four guiding principles: optimized total solutions instead of isolated individual components, continuous innovation, a “zero defects” quality standard achieved through stable management and strict control, and long-term, partnership-based collaboration with customers. This is underpinned by a quality management system certified to ISO 9001 and ISO 14001.

FASTECH's closed-loop stepping drives are used today in demanding manufacturing and testing environments — for example in LCD/OLED production, semiconductor manufacturing, assembly, packaging and inspection systems, as well as in medical diagnostic devices and laboratory equipment. Industry-standard NEMA mounting flanges make it easy to integrate the drives into existing mechanical designs.

• Proven technology — closed-loop stepping with no tuning effort, developed by a manufacturer with over 20 years of focus on exactly this field
• Open system integration — connectivity to common field networks (EtherCAT, PROFINET, Ethernet, CC-Link IE TSN) for use in existing automation environments
