3.6.2.6 Analog input signals
3.6.2.7 Analog output signal
Depending on how parameters P1-12 and P1-13 are set, control signal
terminals 6 (AI1) and 10 (AI2) can be connected to analog signals
(￫ figure 84):
• 0 - +10 V
• 0 - 10 V with scaling and operating direction change
• 0 - 20 mA
• 4 - 20 mA or 20 - 4 mA with cable breakage monitoring (< 3 mA)
￫
Control signal terminals 7 and 9 are the common 0 V reference
potential for all analog and digital signals.
Analog signals are available at control signal terminals 8 and 11
(￫ figure 84). These outputs can handle a maximum load of 20 mA.
The output signals can be selected using parameters P2-11 (AO1) and P2-13
(AO2). Parameters P2-12 (AO1) and P2-14 (AO2) are used to configure the
formats for the analog inputs:
Parameter Output
value signal
0 0 - 10 V
1 10 - 0 V
2 0 - 20 mA
3 20 - 0 mA
4 4 - 20 mA
5 20 - 4 m A

Control signal terminals 7 and 9 are the common 0 V reference
potential for all analog and digital signals.
By default, the speed/frequency (AO1) and the output current (AO2) will be
displayed.
