Introduction

1.5 Extended scope for adaptation

Inverter with CU240B-2 and CU240E-2 Control Units

Operating Instructions, 01/2011, FW 4.4, A5E02299792B AB

Parameter Description

P20032 = 5 The AND logic block is enabled by assigning to runtime group 5 (time

slice of 128 ms)

P20033 = 440 Run sequence of the AND logic block within runtime group 5 (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 input of the AND

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 Interconnecting the AND output to the control command ON/OFF1

Explanation of the example using the ON/OFF1 command

Parameter P0840[0] is the input of the "ON/OFF1 command" block of the converter.

Parameter r20031 is the output of the AND block. To interconnect the ON/OFF1 command

with the output of the AND block, set P0840 to 20031.

Principle when connecting BICO blocks using BICO technology

An interconnection between two BICO blocks comprises a connector or binector and a BICO

parameter. The interconnection is always established from the perspective of the input of a

particular BICO block. This means that the output of an upstream block must always be

assigned to the input of a downstream block. The assignment is always made by entering

the number of the connector/binector from which the required input signals are read in a

BICO parameter.

This interconnection logic involves the question: where does the signal come from?
