8 Application Examples
8.2.2 Designing an Example Program
To design the example program, users can divide the program into four sections including OX0~M2,
O100~M102, P255~SRET and P0~SRET explained below.
1. OX0~M2: Setting the function parameters of X-axis and Y-axis
When DVP-20PM runs and motion subroutine (OX) is ready (M1792 = ON), set ON X0 to enable
OX0 motion subroutine. OX0 will set up parameters for zero return, JOG speed, and input terminal
polarity on X-axis/Y-axes.
Next, enable zero return and move to (-200000, -200000) on X-axis/Y-axis by 100 kHz then reset
the current position to 0 and call P0 subroutine. OX0 subroutine will end when the execution of P0
subroutine is completed.
If users need to set up other control modes, please refer to explanations on special registers in
Chapter 3.

Zero return speed (VRT) of the X-axis = 200kHz
Zero return deceleration speed (VCR) of the X-axis = 200kHz
Zero return speed (VRT) of the Y-axis = 200kHz
Zero return deceleration speed (VCR) of the Y-axis = 200kHz
JOG speed of the X-axis = 100kHz
JOG speed of the Y-axis =100kHz
Set up input terminal polarity of the X-axis/Y-axis
Enable zero return on the X-axis/Y-axis
Move to (-200000,-200000) on the X-axis/Y-axis by 100kHz.
Clear the current position of the X-axis to 0.
Clear the current position of the Y-axis to 0.
Call the subroutine P0.
2. O100~M102: Main program control
O100 main program controls whether to enable OX0 subroutine. When X0 (drive contact for
enabling OX0) and M1792 (indicating ready status of OX) in the program are ON, OX0 subroutine
will be enabled. You can further place other operations in the main program.
