Analogue inputs 1-4
2.4.3.1
AI1 signal selection
ID377 “AI1 Signal Sel”
2.4.4.1
AI2 signal selection
ID388 “AI2 Signal Sel”
2.4.5.1
AI3 signal selection
ID141 “AI3 Signal Sel”
2.4.6.1
AI4 signal selection
ID152 “AI4 Signal Sel”
Connect the AI3/AI4 signal to the analogue input of your choice with this parameter.
When the analogue input selection parameter is set to
0.1
, you can control the analogue
input monitoring variable from fieldbus by assigning a process data input ID number to
the monitoring signal. This allows the scaling function on the drive side to PLC input
signals.
2.4.3.2
Analogue input 1 signal filtering time ID324 “AI1 Filter Time”
2.4.4.2
Analogue input 2 signal filtering time ID329 “AI2 Filter Time”
2.4.5.2
Analogue input 3 signal filtering time ID142 “AI3 Filter Time”
2.4.6.2
Analogue input 4 signal filtering time ID153 “AI3 Filter Time”
First order filtering is used for the analogue input signals 3 and 4.
