Description
5090
Proportional gain 2
2
0.01 to 100.00
[1.00]
This parameter defines the
proportional coefficient that
specifies the gain of the 2nd PID
controller. By increasing the gain,
the response is increased to
permit larger corrections to the
variable to be controlled. The
farther outside tolerances the
process is, the larger the response
action is to return the process to
the tolerance band.
5091
Integral gain 2
2
0.01 to 100.00
[1.00]
This parameter defines the
integral gain that identifies the I
part of the 2nd PID controller. The
integral gain corrects for any
offset (between setpoint and
process variable) automatically
over time by shifting the
proportioning band. Reset
automatically changes the output
requirements until the process
variable and the setpoint are the
same.
This parameter permits the user
to adjust how quickly the reset
attempts to correct for any offset.
5092
Derivative ratio 2
2
0.01 to 100.00
[0.01]
This parameter defines the D part
of the 2nd PID controller. By
increasing this parameter, the
stability of the system is
increased. The controller will
attempt to slow down the action
of the actuator in an attempt to
prevent excessive overshoot or
undershoot. Essentially this is the
brake for the process. This portion
of the PID loop operates anywhere
within the range of the process
unlike reset.

Freq. control with

MPU
[Gen.frequency]
Determining the speed source for
the frequency controller.
MPU: The source for the speed
control is the speed input. Usually
the connected MPU or the J1939
speed. Refer to ID 15155 Engine
speed source" for more
information.
The rpm value is internally
calculated to an Hz value and
