122 == Explanation ==
123
124 The program uses M0,M1,M2 as the switch button of three modes of actions.
125
126 When M0 is turned on, the Y0 servo motor rotates 5000 pulses in the direction of Y3.
127
128 When M1 is turned on, the Y0 servo motor rotates 20,000 pulses at the speed of 4,000 pulses, and Y3 represents the direction of the motor.
129
130 When M2 is turned on, the Y0 servo motor moves to the absolute position of 2000 at the speed of 4000 pulses, and Y3 represents the direction of the motor.

170 In this operation mode, the next operation position number can be set when operating the current position number. There is no waiting time between each position, and the interval time is determined by the instruction delay of the host computer. The operationg position number is determined by the DI terminal logic, and the related function codes are shown in Table 6-16.Table 6-16.

180 The multi-position position number is a 4-digit binary number, and the DI terminal logic is level valid. When the input level is valid, the position selection bit value is 1, otherwise it is 0. Table6-17 shows the correspondence between the position bits 1~~4 of the internal multi-position and the position number.
