For standardization of actual values: (
Section 8.9 "Standardization of setpoint/target values").
0 = Off
, the analog input has no function. After the VFD is enabled via the control terminals, it
will supply the set minimum frequency (P104).
1 = Setpoint 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 for the functionality of the
potentiometer
(P1 or P2) on the SK 2x5E or the
analog input
(AIN1 or AIN2) on the
SK 2x0E.
SK 2x0E: lower limit: 1 Hz
Standardization: T_min. frequency = 50 Hz*U[V]/10 V (U=voltage potentiometer (P1 or
P2)) or U = voltage at analog input (AIN1 or AIN2)
5 = Maximum frequency
is a typical setting for the functionality of the
potentiometer
(P1 or P2) on the SK 2x5E or the
analog input
(AIN1 or AIN2) on the
SK 2x0E.
SK 2x0E: lower limit: 2 Hz
Standardization: T_max. frequency = 100 Hz*U[V]/(U=voltage potentiometer (P1 or P2))
or U = voltage at analog input (AIN1 or AIN2)
6 = Cur. value process controller *
, activates the process controller, analog input is
connected to the actual value encoder (compensator, pressure box, flow volume meter,
etc.). The mode is set via the DIP switches of the I/O extension or in (P401).
7 = Nom. value process controller *
, same as function 6 but the setpoint is specified (e.g.
by a potentiometer). The actual value must be specified using another input.
8 = PI current 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 = PI limited current freq.
*,
"Actual frequency PI limited",
same as function 8 "Actual
frequency PI" but the output frequency cannot fall below the programmed minimum
frequency value in parameter P104. (no change to rotation direction)
10 = PI monitored current freq.
*,
"Actual frequency PI monitored",
same as function 8
"Actual frequency PI" but the VFD 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. When the set limit is reached, there is a reduction of
the output frequency at the torque current limit.
12 = Torque current limit off
,
"Torque current limit switch-off"
depends on parameter (P112).
This value corresponds to 100% of the setpoint. When the set limit 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. When the set limit is reached, the output voltage is reduced in order
to limit the output current.
14 = Current limit off
,
"Current limit switch-off",
depends on parameter (P536). This value
corresponds to 100% of the setpoint. When the set limit is reached, the device switches
off with error code E12.4.
15 = Ramp time
, (only SK 2x0E size 4 and SK 2x5E) is a typical setting for the function of
potentiometer P1 or P2 (P400 [01] or [02]), which are
integrated in the VFD cover
(
Section 4.3.2 "Configuration").
SK 2x0E: lower limit: 50 ms
Standardization: T_ramp time = 10 s*U[V]/10 V (U=voltage of potentiometer (P1 or P2))
16 = Pre-tension Torque
, a function that enables a value for the torque requirement to be
entered beforehand in the controller (interference factor application). This function can be
used to improve loading of lifting equipment with separate load detection.
17 = Multiplication
, the setpoint is multiplied with the analog value indicated. The analog
value adjusted to 100% then corresponds to a multiplication factor of 1.
