摘要
在电梯用PLC控制变频器调速实现电流、速度双闭环的基础上,利用旋转编码器发出的脉冲信号构成位置反馈,使电梯达到精确的位移控制,实现控制系统用电流、速度、位移的三环控制。
PLC control of the elevator speed inverter current implementation, the speed of double-loop, based on the use of rotary encoder pulse signal issued constitute a position feedback, so that the lift to reach the precise displacement control. Control system implementation with current, velocity and displacement of three-ring control.
