Functional Description 101
11.3.8 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

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
PID sleep functionality
This function is controlled via a wait delay and a sepa-
rate wake-up margin condition. With this function it is
possible to put the VSD in “sleep mode” when the proc-
ess value is at it’s set point and the motor is running at
minimum speed for the length of the time set in [386].
By going into sleep mode, the by the application con-
sumed energy is reduced to a minimum. When the

The speed decreases when the feedback
value decreases. PID settings according to
menus [382] to [385].
