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 15: Control signal terminal 4 (AI2)
P-16
Signal
Description
0
0 - +10 V
Frequency reference value / Speed reference value.
Manipulated variable range from minimum (P-02) to maximum (P-01) value.
Default settings.
1
0 - +10 V
Frequency reference value/speed reference value with operating direction
change depending on the parameterization (P-35, P-39)
2
0 - 20 mA
Current signal
3
4 - 20 mA
Current signal with open-circuit monitoring (< 3 mA)
￫
Shutdown with fault message.
4
4 - 20 mA
Current signal with open-circuit monitoring (< 3 mA)
￫
No
shutdown if a fault is detected
Operation will continue with fixed frequency/fixed speed 1 (P-20)
5
20 - 4 mA
Inverted current signal with open-circuit monitoring (< 3 mA)
￫
Shutdown with fault message
6
20 - 4 mA

Thermistor connection (
Section 3.6.3, “Thermistor connection“, page 106)
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.
