Function:
Choose among different units to be shown
on the display.
This unit is also used directly in Process control,
closed loop as a unit for Minimum/Maximum
reference (parameters 204/205) and i.
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 control, open
loop or Torque control, open loop , the unit selected in
parameter 416 can be used in displays (par. 009-12
Feedback [unit]) of process parameters.
The process parameter to be displayed can be
connected in the form of an external analogue
signal to terminal 53 (par. 308: Feedback signal) or
terminal 60 (par. 314: Feedback signal).
Note: The reference can only be shown in Hz (Speed
control, open loop) or Nm (Torque control, open loop).
If par. 100 is selected as Speed control, closed loop
, parameter 416 is not active, since both reference
and feedback are always shown as RPM.
If parameter 100 is selected as Process control, closed
loop, the unit selected in parameter 416 will be used
when displaying both reference (par. 009-12: Reference
[unit]) and feedbac k (par. 009-12: Feedback [unit]).
Scaling of the display indication as a function of the
selected range (par. 309/310, 312/313, 315 and
316) for a connected, external signal is effected
for a reference in parameters 204 and 205 and for
feedback in parameters 414 and 415.
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. A feedback or
process signal connected to terminal 53, 60 or 33
(pulse), will, however, be displayed in the form of the
unit selected in parameter 416. If parameter 013 is
chosen as LCP control/as par. 100 or LCP digital

[34] control/as par. 100, the unit will be as described
above under parameter 002, Remote-control.

NB!:
[37]
The above applies to display of Reference
[38]
[unit] and Feedback [unit]. If Reference [%] or
[39]
Feedback [%] is selected, the value displayed will
[40]
be in the form of a percentage of the selected range.
Description of choice:
Select the desired unit for the reference/feedback signal.
422 U 0 voltage at 0 Hz
(U0 VOLTAGE (0HZ))
Value:
0.0 - parameter 103
Function:
Parameters 422-432 can be used together with Special
motor characteristics (par. 101). It is possible to
make a U/f characteristic on the basis of six definable
voltages and frequencies. Change of motor nameplate
data (parameter 102 - 106) affects parameter 422.
Description of choice:
Set the desired voltage at 0 Hz.
See the below drawing.
423 U 1 voltage
(U1 VOLTAGE)
Value:
0.0 - U
AKD,MAX
Function:
This parameter sets the Y-value of the 1st break point.
Description of choice:
Set the voltage desired at the F1 frequency
set in parameter 424.
See drawing for parameter 422.
