ID Parameter CL Setting range
[Default]
Description
This parameter is only visible if
load control (parameter
╚═▷ 5525 )
is configured to "PID analog".
5514 Integral gain 2 0.01 to 100.00
[1.00]
The integral gain identifies the I
part of the 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.
Notes
The integral gain constant must
be greater than the derivative
time constant. If the integral gain
constant is too large, the engine
will continually oscillate.
If the integral gain steady is too
small, the engine will take too
long to settle at a steady state.
This parameter is only visible if
load control (parameter
╚═▷ 5525 )
is configured to "PID analog".
5515 Derivative ratio 2 0.01 to 100.00
[0.01]
The derivative ratio identifies the
D part of the 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.
Notes
This parameter is only visible if
load control (parameter
╚═▷ 5525 )
is configured to "PID analog".
The default configured controller
acts like a PI controller what is the
valid D part setting for systems
with secondary controllers.
5560 Deadband 1 0.10 to 9.99%
[1.00%]
The generator load is controlled in
such a manner, when paralleled
with the mains, so that the
monitored load does not deviate
