The basic equipment of SK 2x5E devices does not include an analog input. An analog function
can only be implemented by the use of options (Array [-01]...[-05] and [-
08]…[-09]) or by use of
the digital input 2 or 3 (Array [-06]...[-07]). The following settings are then possible:
For standardisation of actual values: See also (Section 9.10).
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 point frequency, the specified 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 subtract, "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 5.2.2).
Standardisation: T_Min.-frequency= 50Hz*U[V]/10V (U=voltage potentiometer (P1 or P2))
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 5.2.2).
Standardisation: T_Max.-frequency= 100Hz*U[V]/10V (U=voltage potentiometer (P1 or P2))
6 = Cur val process ctrl, "Current value process controller" *, activates the process
controller analog input is connected to the actual value sensor (compensator, air can,
flow volume meter, etc.). The mode is set via the DIP switches of the I/O extension or in
(P401).
7 = Nom val process ctrl, "Nominal value 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 = Actual PI frequency *, is required to build up a control loop. 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
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)
10 = Actual freq. PI monitored *, "Actual frequency PI monitored", as for function 8 "Actual
frequency PI", however the FI switches the output frequency off when the minimum
frequency P104 is reached
11 = Torque current limit, "Torque current limited" depends on parameter (P112). This value
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.
12 = Torque current limit switch-off, "Torque current limit switch-off" depends on parameter
(P112). This value corresponds to 100% of the setpoint value. When the set limit value
is reached, the device switches off with error code E12.3.
13 = Current limit, "Current limited" depends on parameter (P536). This value corresponds to
100% of the setpoint value. When the set limit value is reached, the output voltage is
reduced in order to limit the output current.
14 = Current switch-off, "Current limit switch-off", depends on parameter (P536), this value
corresponds to 100% of the setpoint value. When the set limit value is reached, the
device switches off with error code E12.4.
15 = Ramp time, (only SK 2x0E S 4 and SK 2x5E) is a typical setting value for the function of
potentiometer P1 or P2 (P400 [01] or [02]), which are integrated into the cover of the FI
(Section 5.2.2). Standardisation: T_Ramp time= 10s*U[V]/10V (U=Voltage of
potentiometer (P1 or P2))
16 = Pre-tension Torque, 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 specified analog value. The analog
value adjusted to 100% then corresponds to a multiplication factor of 1.
18 = Curve control, "Curve travel calculator", via the external analog input (P400 [-03] or
P400 [-04]) or via the BUS (P546 [-01 .. -03]) the master receives the actual speed from
the slave. From its own speed, the slave speed and the guide speed, the master
