DQ3HB78M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*的控制电路结合一起所构成的新一代全数字步进电机驱动器。驱动电压为DC24V-80V,适配电流在7.0A以下、外径57-86mm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、小型数控机床、包装机械等分辨率较高的中、小型数控设备上。
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:DC24V-80V
●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)
