3.4.2.3 Analog input signals
Depending on how parameters P-12 and P-15 are set, control signal termi-
nals 4 (AI2) and 6 (AI1) can be connected to analog signals.
• 0 - +10 V
• 0 - 10 V with scaling and operating direction change
• 0 - 20 mA
• 4 - 20 mA or 20 - 4 mA with open-circuit monitoring (< 3 mA)
3.4.2.4 Analog output signal
An analog voltage signal (0 - +10 V) is available on control signal terminal 8.
This output can handle a maximum load of 20 mA.
The output signal is adjusted with parameter P-25 ( Table 12, Page 98).
