46.1. Overview
The Sinus Penta is provided with two separate PID (Proportional, Integral, Derivative) regulators allowing performing
regulation loops such as pressure control, delivery control, etc., with no need to connect external auxiliary devices.
The PID Configuration Menu defines configuration parameters for the two PID regulators.
The configuration parameters for the PID regulator can be modified only when the drive is in stand-by and they set the
following variables: reference sources, feedback sources and type of PID output action.
The programming parameters for the two PID regulators, including coefficients of proportional, integral and derivative
terms, output saturation, etc., are covered in the PID PARAMETERS MENU and the PID2 PARAMETERS MENU.
46.2. Operation and Structure of the PID Regulator
Figure 69: Structure of the PID Regulator
The figure above illustrates the block diagram of the PID regulator. Each block is described below:
Block 1: PID reference sources
Multiple reference sources can be selected at a time (up to 3 reference sources can be selected with parameters
C285
,
C286
,
C287
).
The resulting reference value depends on the setup in
C291a
(see block 3).
Dynamic selection is possible between two reference sources using the digital input configured as the source selector
(see
C179
and
C179b
); this parameter has effect only if the Two PIDs mode is activated.
Block 2: PID feedback sources
Multiple feedback sources can be selected at a time (up to 3 feedback sources can be selected with parameters
C288,
C289, C290
).
The resulting reference value depends on the setup in
C291a
(see block 3).
Dynamic selection is possible between two feedback sources using the digital input configured as the source selector
(see
C179
and
C179b
); this parameter has effect only if the Two PIDs mode is activated.
