ID Parameter CL Setting range
[Default]
Description
will take too long to settle at a
steady state.
Notes
This parameter is only visible if
power factor control
(parameter
╚═▷ 5625 ) is
configured to "PID analog".
5615 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
power factor control
(parameter
╚═▷ 5625 ) 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.
5660 Deadband 1 0.001 to 0.300
[0.010]
The generator power factor is
controlled in such a manner, when
paralleled with the mains, so that
the monitored power factor does
not deviate from the configured
power factor setpoint by more
than the value configured in this
parameter without the controller
issuing a raise/lower signal to the
voltage regulator.
This prevents unneeded wear on
the raise/lower relay contacts.
Notes
This parameter is only visible if
power factor control
(parameter
╚═▷ 5625 ) is
configured to "3pos controller".
5661 Time pulse minimum 1 0.01 to 2.00 s
[0.05 s]
A minimum pulse on time must be
configured here.
The shortest possible pulse time
should be configured to limit
overshoot of the desired power
factor reference point.
