[-07] Setpoint module
... Setting values below.
For standardisation of actual values:

Section 8.9 "Standardisation of setpoint / target values".
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
, setting for minimum frequency of frequency inverter
Lower limit: 1 Hz
Standardisation: 0 - 100% of P104
5 = Maximum frequency
, setting for maximum frequency of frequency inverter
Lower limit: 2 Hz
Standardisation: 0 - 100% of P105
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)
10 = Actual freq. PID monitored
*, "Actual frequency PID 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.
