12.2.3 Analog Input Configuration
Please read through the information on 'Wiring diagram' and 'Terminals' before
configuration of 'Analog inputs AI1, AI2', see chapter 8 "Frequency Converter
Wiring" on page 41 and chapter "Analog inputs" on page 55 respectively. To con-
figure these two inputs, take the following steps:
Step 1: Select the input mode
Code Name Setting range Default Min. Attri.
E1.35 AI1 input mode 0: 0...20 mA
1: 4...20 mA
2: 0...10 V
3: 0...5 V
4: 2…10 V
2 – Run
E1.40 AI2 input mode 1 – Run
When AI1 or AI2 is set to 4...20 mA, or 2...10 V, the broken wire de-
tection for analog input can be configured, see chapter "Analog Input
Broken Wire Detection" on page 203.
Step 2: Set the channel gain and filter time
Code Name Setting range Default Min. Attri.
E1.38 AI1 gain 0.00...10.00 1.00 0.01 Run
E1.43 AI2 gain 0.00...10.00 1.00 0.01 Run
E1.69 Analog input filter time 0.000...2.000 s 0.100 0.001 Run
When AI1 or AI2 input is used as the reference frequency input channel, see
chapter "Adjust the setting frequency by analog inputs" on page 133.
Step 3: Select input curve
AI1 and AI2 inputs can use both curve 1 and curve 2, see chapter 12.2.2 " X5
Pulse Input Configuration" on page 108.
Analog input status is monitored by parameter d0.30 'AI1 input' /
d0.31 'AI2 input'.
