DQ3HB220M是基于DSP控制的三相步进电机驱动器。它是将*的DSP控制芯片和三相逆变驱动模块结合一起所构成的新一代数字步进电机驱动器。驱动电压为AC110V-220V,适配电流在7.0A以下、外径57-130mm的各种型号的三相混合式步进电机。该驱动器内部采用类似伺服控制原理的电路,此电路可以使电机运行平稳,几乎没有震动和噪音,电机在*时,力矩大大高于二相和五相混合式步进电机。定位精度*高可达60000步/转。该产品广泛应用于雕刻机、中型数控机床、电脑绣花机、包装机械等分辨率较高的大、中型数控设备上。
特点
● *、*格
● 设有16档等角度恒力矩细分,*高分辨率60000步/转
● *高反应频率可达200Kpps
● 步进脉冲停止*过100ms时,线圈电流自动减到设定电流的一半
● 光电隔离信号输入/输出
● 驱动电流1.2A/相到7.0A/相分16档可调
● 单电源输入,电压范围:AC110V-220V
●相位记忆功能(注:输入停止*过3秒后,驱动器自动记忆当时电机相位,重新上电或MF信号由低电平变为高电平时,驱动器自动恢复电机相位)。
