11.3.9 PID Process Control [380]
The PID controller is used to control an external process via
a feedback signal. The reference value can be set via analogue
input AnIn1, at the Control Panel [310] by using a Preset
Reference, or via serial communication. The feedback signal
(actual value) must be connected to an analogue input that
is set to the function Process Value.
Process PID Control [381]
This function enables the PID controller and defines the
response to a changed feedback signal.
Communication information
PID P Gain [383]
Setting the P gain for the PID controller.
Communication information
Fig. 95 Closed loop PID control
PID I Time [384]
Setting the integration time for the PID controller.
Communication information
Process PID D Time [385]
Setting the differentiation time for the PID controller.
Communication information
Default: Off
Off 0 PID control deactivated.
On 1
The speed increases when the feedback
value decreases. PID settings according to
menus [381] to [385].
Invert 2
The speed decreases when the feedback
value decreases. PID settings according to
menus [383] to [385].
