Function:
Choose among different units to be shown on the display.
This unit is also used directly in
Process regulation, closed
loop
as a unit for
Minimum/Maximum reference
(parameters
204/205) and
Minimum/ Maximum feedback
(parameters
414/415).
The possibility of choosing a unit in parameter 416 will
depend on the choices made in the following parameters:
Par. 002
Local/remote control.
Par. 013
Local control/config. as par. 100.
Par. 100
Configuration
.
Select parameter 002 as Remote control
If parameter 100 is selected as
Speed regulation, open loop
,
the unit selected in parameter 416 can be used in displays
(par. 009-12
Feedback [unit]
) of process parameters.
Note: The reference can only be shown in Hz
(Speed
regulation, open loop
).
If parameter 100 is selected as
Process regulation, closed
loop
, the unit selected in parameter 416 will be used when
displaying both reference (par. 009- 12:
Reference [unit]
)
and feedback (par. 009-12:
Feedback [unit]
).
Select parameter 002 as Local control
If parameter 013 is chosen as
LCP control and open loop
or
LCP digital control and open loop
, the reference will be
given in Hz, regardless of the choice made in parameter
416. If parameter 013 is chosen as
LCP control/as par
. 100
or
LCP digital control/as par. 100
, the unit will be as
described above under parameter 002,
Remote-control
.
Description of choice:
Select the desired unit for the reference/feedback signal.
3.5.3 FCM 300 Regulator
Process regulation
The PID regulator maintains a constant process mode
(pressure, temperature, flow, etc.) and adjusts the motor
speed on the basis of the reference/setpoint and feedback
signal.
A transmitter provides the PID regulator with a feedback
signal from the process as an expression of the process's
actual mode. The feedback signal varies as the process
load varies.
This means that there is a variance between the reference/
setpoint and the actual process mode. This variance is
compensated by the PID regulator by means of the output
frequency being regulated up or down in relation to the
variance between the reference/setpoint and the feedback
signal.
The integrated PID regulator in the frequency converter
has been optimised for use in process applications. This
means that there are a number of special functions
available in the frequency converter.
Previously it was necessary to obtain a System to handle
these special functions by installing extra I/O modules and
programming the System. With the frequency converter
the need to install extra modules can be avoided. The
