用高性能plc和伺服驱动器实现对传动、扭矩和逻辑动作全自动控制

high performance plc and servo actuator are used to realize automatic control of transmission, torque and logical action

1、传动电机均为伺服电动机，通过扭矩控制作为各传动部位的同步闭环反馈，实时快速各部位的同步扭矩，由伺服特殊功能控制扭矩信号，通过由plc进行pid运算后精确控制各部位的扭矩，实现各电机之间的速度同步和扭矩闭环自动控制。

driving motors are the servo motors, the torque control is used as the synchronous closed-loop feedback of each transmission part,real-time and fast synchronous torque of all parts,torque signal is controlled by servo special function.the torque of each part is controlled accurately after pid operation by plc. to realize the speed synchronization and torque closed-loop automatic control among the motors

3、扭矩控制精度：±0.3kg。

torque control accuracy:±0.3kg

4、扭矩恢复时间10秒。

torque recovery time: 10 seconds.

5、张力控制具有区间报警和过载自动停机功能

   the tension control with the function of interval alarm and overload automatic stop

6、速度需平稳升降，具有连续可调功能，加减速时间可调

the speed should rise and fall steadily, with continuous adjustable function and adjustable acceleration and deceleration time
