428 F3 frequency
(F3 FREQUENCY)
Value:
Par. 426 F2 frequenc y - 1000 Hz
✭ Par. 104 Motor frequency
Function:
See parameter 423 U1 voltage.

output voltage (U3), parameter 427 U3 voltage .
NB!:
Parameters 437-444 are only used
if in parameter 100 Configuration a
selection has been made of Process
regulation, closed loop. [3].
437 Process PID normal/inverse control
(PROC NO/INV CTRL)
Value:
✭Normal (NORMAL)
[0]
Inverse (INVERSE)
[1]
Function:
It is possible to choose whether the process regulator
is to increase/reduce the output frequency if there
is a deviation between the reference/setpoint
and the actual process mode.
Description of choice:
If the frequency converter is to reduce
the output frequency in case the feed-
back signal increases, select Normal [0].
If the frequency converter is to increase the
output frequency in case the feedback signal
increases, select Inverse [1].
