Analog input (P2)

In parameter group P2, you can adapt the analog inputs:
The signal range depends on the switch position of the
microswitches (see figure 68):
• S2 = V: AI1 (control signal terminal 2), voltage signal
0/2 - +10 V.
• S3 = mA: AI2 (control signal terminal 4), current signal
0/4 - 20 mA.
Reference potential for the analog inputs (AI1, AI2) is GND
(control signal terminals 3 and 5).
h The allocation of the analog inputs (AI1, AI2) can be set
under parameter P6.2 and P6.18 (setpoint input) as well
as P9.5 and P9.6 (PI controller, actual value).

Value Description
AI1 Signal range (Analog input).
Depending on the switch position of microswitch S2
(FS = frequency setpoint).
0 S2 = V: 0 - +10 V, voltage signal (FS, a P6.2).
S2 = mA: 0 - 20 mA, current signal.
1 With live-zero,
S2 = V: 2 - +10 V, voltage signal,
S2 = mA: 4 - 20 mA, current signal.
a At P8.1 it is possible to set the response of the MMX to a
setpoint error (life zero).
AI1 Custom Min
Scaling (-100.00 % - 100.00 %) of the analog input signal (V/mA)
in the zero range (minimum response value).
a section "Scaled value range (AI1, AI2)", page 76.
AI1 Custom Max
Scaling (-100.00 % - 100.00 %) of the analog input signal (V/mA)
in the limit value range (highest limit value).
a section "Scaled value range (AI1, AI2)", page 76.
AI1 Filter time
0.0 no filter function.
0.1 - 10.0 s = Filter time constant for the analog input signal
(V/mA).
