1概述/Overview
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.

3.2 安装方法/Installation method
驱动器的可靠工作温度通常在 60℃以内，电机工作温度为 80℃以内。
The reliable operating temperature of the driver is usually within 60℃，and the motor
operating temperature is within 80℃。
建议使用时选择自动半流方式，马达停止时电流自动减一半，以减少电机和驱动器的发热。
It is recommended to use the automatic semi-flow mode when using the motor. When the
motor stops, the current is automatically reduced by half to reduce the heat of the motor
and the drive。
安装驱动器时请采用竖着侧面安装，使散热齿形成较强的空气对流。
Install the drive with vertical side mounting so that the heat dissipating teeth form
a strong air convection。
必要时机内靠近驱动器处安装风扇，强制散热，保证驱动器在可靠工作温度范围内工作。
Install a fan near the drive when necessary to force heat dissipation to ensure that
the drive works within a reliable operating temperature range。

红色 LED 为故障指示灯，当出现故障时，该指示灯以 3 秒钟为周期循环闪烁；当故障被用户清除时，红
色 LED 常灭。红色 LED 在 3 秒钟内闪烁次数代表不同的故障信息，具体关系如下表所示。
LED power indicator is green, when the drive power, the LED is lit; when the drive power
is cut off, the LED is off. Fault indicator red LED, when a failure occurs, the indicator is
blinking cycle to cycle 3 seconds; the user when the fault is cleared, the red LED is off.
