Appendix D How to Use PLC Function
VFD-E Series
D-38 Revision August 2006, 01EE, SW--PW V1.03/CTL V2.03
Explanations:
The ORP commands are used in the parallel connection of the contact’s rising-edge detection.
Program Example:
Ladder diagram: Command code: Operation:
LD X0 Load A contact of X0
ORP X1 X1 rising-edge detection in parallel
connection
X0
X1
Y1
OUT Y1 Drive Y1 coil
Mnemonic Function
ORF Falling-edge parallel connection
X0~X17 Y0~Y17 M0~M159 T0~15 C0~C7 D0~D29 X0~X17

Explanations:
When X0=OFFШON (rising-edge trigger), PLS command will be executed and M0 will send the
pulse of one time which the length is a scan time.
