Description
Defines the time for which the monitored signal must
continuously stay above the overload curve before the drive
takes the action selected by
Overload timer.
Defines the time for which the monitored signal must
continuously stay below the underload curve before the drive
takes the action selected by
Underload timer.
Parameter values for process PID control.
The drive contains a single active PID controller for process
use, however two separate complete set-ups can be
programmed and stored.
The first set is made up of parameters 40.07...40.56*, the
second set is defined by the parameters in group
PID set 2. The binary source that defines which set is used is
selected by parameter 40.57 PID set1/set2
See section Process PID control
chain diagrams on pages
*The remaining parameters in this group are common for both
sets.
Displays the output of the process PID controller. See the
control chain diagram on page 599.
This parameter is read-only. The unit is selected by parameter
40.12 Set 1 unit selection.
Process PID controller output.
Displays the value of process feedback after source selection,
mathematical function (parameter
function), and filtering. See the control chain diagram on page
598.
This parameter is read-only. The unit is selected by parameter
40.12 Set 1 unit selection.
Process feedback.
Displays the value of process PID setpoint after source
selection, mathematical function
function), limitation and ramping. See the control chain
diagram on page 599.
This parameter is read-only. The unit is selected by parameter
40.12 Set 1 unit selection.
Setpoint for process PID controller.
Displays the process PID deviation. By default, this value
equals setpoint - feedback, but deviation can be inverted by
parameter 40.31 Set 1 deviation
chain diagram on page 599.
This parameter is read-only. The unit is selected by parameter
