A.4 Interconnecting signals in the inverter

p20158 = 722.0

p20030[0] = 20160

p20030[1] = 722.1

p0840 = 20031

Explanation of the application example using the ON/OFF1 command

Parameter p0840[0] is the input of the "ON/OFF1" block of the inverter. Parameter r20031 is

the output of the AND block. To interconnect ON/OFF1 with the output of the AND block, set

p0840 = 20031.

Connect the status of DI 0 to the input of the time block

r0722.0 = Parameter that displays the status of digital input 0.

Interconnecting the time block to the 1st AND input

Interconnecting the status of DI 1 to the 2nd AND input

r0722.1 = Parameter that displays the status of digital input 1.

Interconnect the AND output to ON/OFF1

Interconnecting blocks by setting p0840[0] = 20031
