FigureA-4 Signal interconnection for control logic
The signal of digital input0 (DI0) is fed through a time block (PDE0) and is interconnected
with the input of a logic block (AND 0). The signal of digital input 1 (DI 1) is interconnected to
the second input of the logic block. The logic block output issues the ON/OFF1 command to
switch-on the motor.
Setting the control logic
Parameter Description
p20161 = 5 The time block is enabled by assigning to runtime group5 (time slice of
128ms)
p20162 = 430 Run sequence of the time block within runtime group 5 (processing before
the AND logic block)
p20032 = 5 The AND logic block is enabled by assigning to runtime group 5 (time slice of
128ms)
p20033 = 440 Run sequence of the AND logic block within runtime group5 (processing
after the time block)
p20159 = 5000.00 Setting the delay time [ms] of the time module: 5 seconds
p20158 = 722.0 Connect the status of DI 0 to the input of the time block
r0722.0 = Parameter that displays the status of digital input 0.
p20030[0] = 20160 Interconnecting the time block to the 1st AND input
p20030[1] = 722.1 Interconnecting the status of DI 1 to the 2nd AND input
r0722.1 = Parameter that displays the status of digital input 1.
p0840 = 20031 Interconnect the AND output to ON/OFF1
Explanation of the application example using the ON/OFF1 command
Parameter p0840[0] is the input of the "ON/OFF1" block of the converter. Parameter r20031
is the output of the AND block. To interconnect ON/OFF1 with the output of the AND block,
set p0840=20031.
