3 integrated into the FI. With this setting, digital input DIN3 is set to evaluate pulse
signals. The pulses are then evaluated as an analog signal according to the function
which is set here.
In addition to the internal analog inputs, analog functions from the digital inputs DIN 2 and DIN 3
or the analog inputs of optional IO extension modules can also be processed.
Assignment of the analog functions is carried out in the relevant array of paramet
er P400. The
possible analog functions can be found in the following table.
Assignment of digital functions to the analog inputs 1 and 2 of the motor controller is carried out in
parameter P420 [-08] or [-09]. The functions which can be set correspond to t
hose of the digital
inputs (see table after P420).
The possible functions are listed in the following tables.

List of possible analog functions of the analog inputs
Value
Function
Description
00
Off
The analog input has no function. After the FI has been enabled via the control
terminals, it will supply the set minimum frequency (P104).
01
Setpoint frequency
The specified analog range (matching of analog input) varies the output frequency
between the set minimum and maximum frequencies (P104/P105).
02
Torque current limit
Based on the set torque current limit (P112), this can be altered by means of an analog
value. 100% setpoint here corresponds to the set torque current limit P112.
03
Actual frequency PID*
Is required in order to set up a control circuit. The analog input (actual value) is
compared with the setpoint (e.g. fixed frequency).
The output frequency is adjusted as
far as possible until the actual value equals the setpoint (see control values
P413...P415).
04
Frequency addition **
The supplied frequency value is added to the setpoint.
05
Frequency subtraction**
he supplied frequency value is subtracted from the setpoint.
06
Current limit
Based on the set current limit (P1536), this can be altered via the analog input.
07
Maximum frequency
The maximum frequency of the FI is varied. 100% corresponds to the setting in
parameter P411. 0% corresponds to the setting in parameter P410. The values for the
minimum/maximum output frequencies (P104/P105) cannot be undershot/exceeded
