Delta AS Series Programming Manual page 1190

Example 1
When M10 is ON, Y0.0 outputs 20,000 pulses at 2 kHz (relative positioning). Y0.1 = OFF means the positive direction.
Additional remarks
1.
The following graph explains the relative positioning by specifying the travel distance from the current position with
the +/- signs.

b)
You can create several DRVI instructions using the same output point in the program. The PLC can start only
one DRVI instruction when executing the program. For example, when one instruction starts Y0.0 for output,
then other instructions that also use Y0.0 for output are not executed. The instruction that starts the output
point first uses the point first.
c)
After the instruction is executed, any modification of the parameters is not accepted until the instruction is
disabled.
