For standardisation of actual values: ( Section 8.9 "Standardisation of setpoint / target values").
10 = Actual freq. PID monitored *, "Actual frequency PID monitored", as for function 8 Actual
11 = Torque current limit, "Torque current limited" depends on parameter (P112). This value
12 = Torque current limit switch-off, "Torque current limit switch-off" depends on parameter
13 = Current limit, "Current limited" depends on parameter (P536). This value corresponds to
14 = Current switch-off, "Current limit switch-off", depends on parameter (P536), this value
15 = Ramp time, (only SK 2x0E size 4 and SK 2x5E) is a typical setting value for the function
16 = Torque precontrol, a function that enables a value for the anticipated torque requirement
17 = Multiplication, the setpoint is multiplied with the analogue value supplied. The analogue

0 = Off, the analogue input has no function. After the FI has been enabled via the control
terminals, it will supply the set minimum frequency (P104).
1 = Setpoint frequency, the given analogue range (P402/P403) varies the output frequency
between the set minimum and maximum frequencies (P104/P105).
2 = Frequency addition **, the supplied frequency value is added to the setpoint.
3 = Frequency subtraction **, the supplied frequency value is subtracted from the setpoint.
4 = Minimum frequency, is a typical setting for the functionality of the
potentiometer (P1 or P2) at the SK 2x5E or the analogue input (AIN1 or AIN2) at the
SK 2x0E.
SK 2x0E: lower limit: 1 Hz
Standardisation: T_Min. frequency= 50Hz*U[V]/10V (U=voltage potentiometer (P1 or P2))
or U = voltage at analogue input (AIN1 or AIN2)
5 = Maximum frequency is a typical setting for the functionality of the
potentiometer (P1 or P2) at the SK 2x5E or the analogue input (AIN1 or AIN2) at the
SK 2x0E.
SK 2x0E: lower limit: 2 Hz
Standardisation: T_Max. frequency= 100Hz*U[V]/(U=voltage potentiometer (P1 or P2)) or
U = voltage at analogue input (AIN1 or AIN2)
6 = Actual value process controller *, activates the process controller, analogue input is
connected to the actual value encoder (compensator, air can, flow volume meter, etc.).
The mode is set via the DIP switches of the I/O extension or in (P401).
7 = Setpoint process controller *, as for Function 6, however, the setpoint is specified (e.g.
by a potentiometer). The actual value must be specified using another input.
8 = Actual PI frequency *, is required to build up a control loop. The analogue 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
variables P413...P414)
9 = Actual freq. PI limited *, "Actual frequency PI limited", as for function 8 "Actual frequency
PI", however the output frequency cannot fall below the programmed minimum frequency
value in Parameter P104. (no change to rotation direction)
frequency PI", however the FI switches the output frequency off when the minimum
frequency P104 is reached
corresponds to 100% of the setpoint value. When the set limit value is reached, there is a
reduction of the output frequency at the torque current limit.

reached, the device switches off with error code E12.3.
100% of the setpoint value. When the set limit value is reached, the output voltage is
reduced in order to limit the output current.
