直接控制扭矩而不是电机转速范围，可以使得电机和变频器产生足够高的扭矩使得压机可以回复到原来的位置。
Direct control of torque over the motor speed range is provided by the drive, which helps the motor and drive generate torque levels high enough to cycle the press back to ready position.
硬件由微机、步进电机控制卡、步进电机驱动器和步进电机等器件组成。
Hardware consists of microcomputer, stepping motor control card, stepping motor driver and stepping motor and so on.
采用交流伺服电机作为驱动器件，可以和直流伺服电机一样构成高精度，高性能的半闭环或闭环控制系统。
