stepper drive

概述 Overview

DM3522 是新推出的数字式三相步进电机驱动器，采用最新 32 位 DSP 技术，主要驱动 86、110 型三相混合式步进电机。微步细分为 16 种，最大步数为
30000 步 / 转；工作峰值电流范围为 2.0A-7.2A，输出电流共 8 种，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，低中高速运行平稳，噪音小。具有半流，过压、过流等保护电路。驱动器内部集成了参数自动整定功能，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。本驱动器为交流供电，推荐工作范围为 AC110V-220V。
The DM3522 is a new digital three-phase stepper motor driver that uses the latest 32-bit DSP technology to drive 86, 110 three-phase hybrid stepper
motors. The microstep is subdivided into 16 types, the maximum number of steps is 30,000 steps/rev; the peak current range is 2.0A-7.2A, and the
output current is 8 kinds, which can meet the application needs of most occasions. Thanks to the built-in micro-segmentation technology, even in the
case of low subdivision, high subdivision can be achieved, with low, medium and high speed running smoothly and low noise. It has protection circuits
such as half flow, over voltage and over current. The parameter internal auto-tuning function is integrated in the drive, which can automatically generate
optimal operating parameters for different motors to maximize the performance of the motor. This driver is AC powered. The recommended working
range is AC110V-220V.

主要技术参数 The main technical parameters

型号 Model DM3522
电压 Voltage AC220V±10%
输出相电流 Output phase current 1.5A-7.2A
电机每转脉冲数 400、500、600、800、1000、1600、2000、3200、4000、
Number of pulses per motor 5000、6000、6400、7500、8000、10000、30000
脉冲控制信号：脉冲上升沿有效；支持 5V-24V 脉冲电压信号，无需外接电阻。本驱动器最高响应 100KHZ，
为了可靠响应脉冲信号，脉冲宽度应大于 5us
PUT+(5-24V) Pulse control signal: pulse rising edge is valid; supports 5V-24V pulse voltage signal, no external
PUL-(PUL)
resistor is needed. The maximum response of this driver is 100KHZ. In order to respond to the pulse
signal reliably, the pulse width should be greater than 5us.
方向信号：高 / 低电平信号，支持 5V-24V 脉冲电压信号，无需外接电阻，为保证电机可靠换向，方向信号应
先于脉冲信号至少 5us 建立。电机的初始运行方向与电机的接线有关，互换任一相绕组如（A+、A- 交换）可
以改变电机初始运行的方向
DIR+(5-24V) Direction signal: high/low level signal, support 5V-24V pulse voltage signal, no external resistor
DIR-(DIR) is needed, in order to ensure reliable commutation of the motor, the direction signal should be
established before the pulse signal is at least 5us. The initial running direction of the motor is related
to the wiring of the motor. Interchanging any phase winding such as (A+, A-exchange) can change
the direction of the initial running of the motor.
使能信号：此输入信号用于使能或禁止。ENA+ 接 +5V，ENA- 接低电平（或内部光耦导通）时，驱动器将切
断电机各相的电流使电机处于自由状态，此时步进脉冲不被响应。当不需用此功能时，使能信号端悬空即可。
当用户使用 24V 时需外接一个 2K 电阻，不需要时可悬空
FREE+(5V) Enable signal: This input signal is used to enable or disable. When ENA+ is connected to +5V and
FREE-(ENA) ENA- is connected to low level (or internal optocoupler is turned on), the driver will cut off the current
of each phase of the motor to make the motor free, and the step pulse will not be responded. When
this function is not needed, the enable signal is left floating. When the user uses 24V, an external 2K
resistor is required, which can be left unconnected when not needed.
ALM+(5V) 当驱动器故障时，红灯亮，光耦报警输出，需外接上拉电阻 When the drive fails, the red light is on, the
ALM-(ALM) optocoupler alarm output, and an external pull-up resistor is required.
