1771-OB 罗克韦尔PLC

凸轮控制器操作手柄使电动机定子和转子电路同时处在左边或右边对应各档控制位置。
左右两边转子回路接线完全一样。当操作手柄处于第一档时，各对触点都不接通，转子
电路电阻全部接入，电动机转速最低。而处在第五档时，五对触点全部接通，转子电路
电阻全部短接，电动机转速最高。
（ 2 ）控制电路分析 凸轮控制器的另外三对触点串接在接触器 KM 的控制回路中，
当操作手柄处于零位时，触点 1-2 、 3-4 、 4-5 接通，此时若按下 SB 则接触器得电
吸合并自锁，电源接通，电动机的运行状态由凸轮控制器控制。
（ 3 ）保护联锁环节分析 控制器 3 对常闭触点用来实现零位保护、并配合两个运
动方向的行程开关 SQ1 、 SQ2 实现限位保护。
