Chapter II. Product Overview
2.1 Introduction
Q2BYG403MD is a two-phase digital hybrid step motor Driver basing
on AC servo control. It is a new generation digital step motor Driver that
integrates advanced DSP control chip and unique control circuit. This
design can increase the integrity significantly, and reduce the size and
weight. The advanced current control algorithm is used to make it have
excellent performance, low vibration, low noise, less heat radiation and
high speed large torque output. Integrate undervoltage, overvoltage and
overcurrent protection, and the reliability is further improved. In
addition, this product also integrates RS-232 serial port communication.
Through PC installed with Driver software, the user can set the
parameters and test, which simplifies the production and test process.
2.2 Features
¾Allow driving 4, 6, 8 wires two-phase step motor
¾Ultra low vibration noise
¾Internal software uses micro-segmentation technology, which can
obtain high segmentation effect in low speed low segmentation
¾Integrate EMF compensation function, and the torque is constant
when the speed is increased
¾Parameter self-tuning
¾Current setting is convenient, and allow selecting freely between
1.2A and 4.2A
¾High precision segmentation, 1~256 optional
¾Pulse response frequency is up to 200KHz
¾Serial port communication, parameter is real-time adjustable,
meeting high performance requirement
¾In still state, the current decreases by half automatically, and the
maximum driving current is 4.2A/phase
¾Integrate protection for undervoltage, overvoltage, short circuit,
etc.
2.3 Application
The Driver is suitable for a variety of small and medium sized
automation equipment and instruments, such as: dispenser, marking
machine, cutting machine, engraving machine, labeling machine, plotter,
automatic assembly equipment, numerical control machine tool, etc. The
application is especially good in the equipment that users expect low
