Parameter Setting value / Description / Note Available with option
P410 (P) Minimum frequency analog input 1/2 always visible
0.0 ... 400.0 Hz
[ 0.0 ]
The minimum frequency that can act on the setpoint via the auxiliary setpoints.
Auxiliary setpoints are all frequencies that have also been entered into the inverter for additional
functions. Actual frequency PID
Frequency addition
Frequency subtraction Auxiliary setpoints via BUS
Minimum frequency above analog setpoint (potentiometer) Process controller
P411 (P) Maximum frequency analog input 1/2 always visible
0.0 ... 400.0 Hz
[ 50.0 ]
The maximum frequency that can act on the setpoint via the auxiliary setpoints.
Auxiliary setpoints are all frequencies that have also been entered into the inverter for additional
functions. Actual frequency PID

P412 (P) Nominal value process controller always visible
0.0 ... 10.0 V
[ 5.0 ]
Fixed specification of a setpoint for the process controller that will only occasionally be altered.
Only with P400 = 14 ... 16 (process controller). Further details can be found in Chap. 8.2
P413 (P) PID control P-component always visible
0 ... 400.0 %
[ 10.0 ]
Only effective if the function Actual frequency PID is selected.
The P-component of the PID controller determines the frequency jump if there is a rule deviation based
on the rule difference.
For example: At a setting of P413 = 10% and a rule difference of 50%, 5% is added to the actual
setpoint.
P414 (P) PID control I-component always visible
0 ... 300.0 ‰ / ms
[ 1.0 ]
Only effective if the function Actual frequency PID is selected.
The I-component of the PID controller determines the frequency change, dependent on time.
P415 (P) PID control D-component always visible
0 ... 400.0 %ms
[ 1.0 ]
Only effective if the function Actual frequency PID is selected.
If there is a rule deviation, the D-component of the PID controller determines the frequency change
multiplied by time.
P416 (P) Ramptime PID setpoint always visible
0 ... 99.99s
[ 2.00 ]
Only effective when the function Actual frequency PID is selected.

P417 (P) Offset analog output 1 STD MLT
-10.0 ... +10.0 V
[ 0.0 ]
In the analog output function an offset can be entered to simplify the processing of the analog signal in
other equipment.
If the analog output has been programmed with a digital function, then the difference between the
switch-on point and the switch-off point can be set in this parameter (hysteresis).
