The basic equipment of SK 200E devices does not include an analog input. An analog function
can only be implemented by the use of options (Array [-01]...[-05]) or by use of the digital input 2
or 3 (Array [-06]...[-07]). The following settings are then possible:
0 = 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).
1 = Set frequency, the given analog 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 value for the function of the potentiometers P1 or
P2 (P400 [01] or [02]), which are integrated in the cover of the FI (Section 4.1.3).
5 = Maximum frequency
, is a typical setting value for the function of the potentiometers P1 or
P2 (P400 [01] or [02]), which are integrated in the cover of the FI (Section 4.1.3).
6 = PI actual value process controller *, activates the process controller, analog input 1 is
connected to the actual value sensor (compensator, air can, flow volume meter, etc.).
The mode (0-10 V or 0/4-20 mA) is set in P401.
7 = PI setpoint process controller *, as function 6, however the setpoint is specified (e.g. by
a potentiometer). The actual value must be specified using another input.
8 = PI controller, actual value*,
9 = PI controller, actual value limited*,
10 = PI controller, actual value monitored*,
11 = Torque current limit (limited), depends on parameter P112. This value corresponds to
100% of the setpoint value. Attainment of the set limiting value causes a reduction of the
output frequency at the limit of the torque current.
12 = Torque current limit (switch-off), depends on parameter P112. This value corresponds
to 100% of the setpoint value. The attainment of this set limiting value causes switch-off
with error code E12.3.
13 = Current limit (limiting), depends on parameter P536. This value corresponds to 100% of
the setpoint value. The attainment of the set limiting value causes a reduction of the
output voltage in order to limit the output current.
14 = Current limit (switch-off), depends on parameter P536. This value corresponds to 100%
of the setpoint value. The attainment of this set limiting value causes switch-off with error
code E12.4.
15 = Ramp time, is a typical setting value for the function of the potentiometers P1 or P2 (P400
[01] or [02]), which are integrated in the cover of the FI (Section 4.1.3).
16 = Torque precontrol, function which enables a value for the anticipated torque requirement
to be entered in the controller (interference factor switching). This function can be used to
improve the load take-up of lift equipment with separate load detection.
17 = Multiplication, the setpoint is multiplied with the analog value supplied. The analog value
adjusted to 100% then corresponds to a multiplication factor of 1.

description.
**) The limits of these values are set by the parameters >Minimum frequency auxiliary
setpoints< P410 and >Maximum frequency auxiliary setpoints< P411.
