Explanation
1.
This instruction specifies the output pulse setting for absolute positioning. S
positioning). The range is between -2,147,483,648 to +2,147,483,647, and +/- signs indicate the positive and
negative pulse directions. When the instruction is executed, it checks the current position with S
not outputting and output completion flag not be set to ON. If 0 is a possible output number in your program, it is
suggested to add more conditions in your program to rule out this possibility.
2.
S is the pulse output frequency and the range is between 0 Hz–4 MHz for the line driver output models and 0 Hz–
2
200 kHz for the open collector output models. If the value in S
(refer to the SR table of DRVI instruction for more details), PLC operates according to the values set in SR.
3.
Absolute positioning means that the instruction outputs pulses to move from current position until the specified target
position is reached. For example, the number of output pulses at current position is 100 and the number of pulses at
the target position S
4.
Refer to the DDRVI instruction (API 2706) for more explanation.
