[1.7 APPLICATION FUNCT.]
(FUn-)
(1) The parameter can also be accessed in the
[1.3 SETTINGS]
(SEt-)
menu.
(2) If a graphic display terminal is not in use, values greater than 9,999 will be displayed on the 4-digit display with a period mark after the
thousand digit, e.g., 15.65 for 15,650.

[Yes]
(YES)
Reversal of the direction of correction (PIC):
If PIC = nO, the speed of the motor will increase when the error is positive. Example: pressure control with
a compressor.
If PIC = YES, the speed of the motor will decrease when the error is positive. Example: temperature control
using a cooling fan.

If the assigned input or bit is at 0, the function is inactive (the PID integral is enabled).
If the assigned input or bit is at 1, the function is active (the PID integral is disabled).
Parameter that can be modified during operation or when stopped.
