The analog input of the FI can be used for various functions. Setting of an analog or digital
function is possible, whereby the selection of the function type is made in parameter P400.
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. 20%
cannot be undershot (with P300=1, not below 10%)!
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
08 Actual PID frequency
limited* Like Function 3, Actual frequency PID, however the output frequency cannot fall below
the programmed minimum frequency value in Parameter P104. (no change to rotation
direction)
09 Actual frequency PID
monitored* Like Function 3, Actual frequency PID, however the FI switches the output frequency
off when the minimum frequency P104 is reached.
10 Servo mode
torque In servo mode ((P300) = "1") the motor torque can be set or limited using this function.
Here the speed controller is switched off and a torque control is activated. The analog
input is then the source of the setpoint value. Above firmware version SW 2.0, this
function can be also be used with reduced control precision without servo mode or for
((P300) = "0").
