Description
provided to the frequency
controller.
Gen.frequency: The electrical
frequency in Hz is the source.
Note: If MPU is enabled check
carefully the relation ship rpm to
electrical frequency. Refer to
parameter "1601 Engine rated
speed" , "1600 Speed input" and
"1602 Fly wheel teeth".
5507 Frequency control 2 [PID analog] The frequency is controlled using
an analog PID controller.
3pos controller The frequency is controlled using
a three-step controller.
Off Frequency control is not carried
out.
5508 Freq. control initial
state
(Frequency control
initial state)
2 0.0 to 100.0%
[50.0%]
The value entered for this
parameter is the start reference
point for the analog output to the
speed controller.
Notes
If the output to the speed control
has been disabled, the output will
act as a control position reference
point.
5510 Proportional gain 2 0.01 to 100.00
[1.00]
The proportional coefficient
specifies the gain. 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.
Notes
If the gain is configured too high,
the result is excessive overshoot/
undershoot of the desired value.
This parameter is only visible if
frequency control (parameter
╚═▷
5507 ) is configured to "PID
analog".
5511 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.
