Activate/deactivate PID control Reset PID and integral
component (PIDC)
With the digital input configured as PID, PID control can be
switched on and off. For a detailed description of the built-in PID
controller, a section “PID control”, page 116. To use the PID
input for activating and deactivating PID control, the PID controller
must be switched on with PNU A071 = 1 (a section “PID
control active/inactive”, page 119). When the PID input is
activated, the PID controller is switched off and the frequency
inverter works with “normal” frequency control.
With the digital input configured as PIDC, the integral component
of the PID control can be reset. If the PIDC input is activated, the
integral component is reset to zero.
X Program one of the digital inputs 1 to 5 as PID by entering the
value 23 under the corresponding PNU (C001 to C005).
X Program one of the digital inputs 1 to 5 as PIDC by entering the
value 24 under the corresponding PNU (C001 to C005).
h
The PID and PIDC inputs are optional. If you want PID
control to be active all the time, you only need to set
PNU A071 to 1.
h
Do not switch the PID controller on and off while the
frequency inverter is in RUN mode (RUN lamp is lit).
h
Do not reset the integral component of the PID controller
while the frequency inverter is in RUN mode (RUN lamp is
lit), as this can lead to overcurrent tripping.
