3.6.2.6 Analog input signals
Depending on how parameters P-12 and P-15 are set, control terminals
4 (AI2) and 6 (AI1) can be connected to analog signals.
Table 14: Control signal terminal 6 (AI1)
P-16 Signal
0 0 - +10 V
1 0 - +10 V
2 0 - 20 mA
3 4 - 20 mA
4 4 - 20 mA
5 20 - 4 mA
6 20 - 4 mA
7 +10 - 0 V
Analog input AI1: Resolution: 12-bit, response time: < 16 ms
Table 15: Control signal terminal 4 (AI2)
P-47 Signal
0 0 - +10 V
1 0 - 20 mA
2 4 - 20 mA
3 4 - 20 mA
4 20 - 4 mA
5 20 - 4 mA

Ptc-th
Analog input AI2: Resolution: 12-bit, response time: < 16 ms
The way control terminal 4 works (DI3 AI2) can be changed with P-15 = 4 and P-12 = 6.

Control terminals 7 and 9 are the common 0 V reference
potential for all analog and digital input signals.
