1.1 产品介绍/Product Introduction
SO88A 是我公司新推出的数字式步进电机驱动器，采用最新 32 位 DSP 数字处理技术，驱动器控制
算法采用先进的变电流技术和先进的变频技术，驱动器发热小，电机振动小，运行平稳。用户可以设置
200~51200 内的任意细分以及额定电流内的任意电流值，能够满足大多数场合的应用需要。由于采用内
置微细分技术，即使在低细分的条件下，也能够达到高细分的效果，低中高速运行都很平稳，噪音超小。
驱动器内部集成了参数上电自动整定功能，能够针对不同电机自动生成最优运行参数，最大限度发挥电
机的性能。
SO88A is a new digital stepper motor driver introduced by our company. It adopts the latest
32-bit DSP digital processing technology. The driver control algorithm adopts advanced
variable current technology and advanced frequency conversion technology. The driver generates
less heat and the motor vibrates less, smooth operation. USERS can set 200 ~ 51200 within the
arbitrary subdivision and rated current within the arbitrary current value, to meet the needs
of most applications. Due to the use of built-in micro-subdivision technology, even in the
conditions of low subdivision, but also can achieve high subdivision effect, low, medium and
high-speed operation is very smooth, ultra-low noise. The auto-tuning function is integrated
in the driver, which can automatically generate the optimal operating parameters for different
motors and maximize the performance of the motors.
