3. P255 ~ SRET: set up 3
rd
axis (Z) control system
The 3rd axis control will activate according to the parameter setting of G00 and G01 instructions. When
G00/G01 sets target position of Z-axis (D1328), P255 will be enabled to drive Y7 (3
rd
axis control signal) and
enabe DVP-EH to control the lift or drop of a pen (i.e. up/down movement of Z axis). For more details, please
refer to G00 and G01 instructions in Chapter 6.

3-axis control signal (Y7) in P255 of DVP-PM drives the input contact X1 of DVP-EH. When X1 is ON, the
step motor controlled by pulses will lift the pen through DDRVI instruction; when X1 is OFF the step motor will
drop the pen through DDRVI instruction.

Connect the input devices Y0 and Y1 in DVP-EH to the pulse input terminals on the step motor.
4. P0 ~ SRET: 2-axis (X, Y) interpolation control
After converting the letters or graphs into G-Codes (NC-Codes), place the G-Code into OX0 subroutine but
into P0 subroutine in order to simplify the program. Operate the P0~SRET section with the 3 sections above
and the drawing of letters or graphs can be performed.
