Communication information
11.3.2 Process Settings [320]
With these functions, the AC drive can be set up to fit the
application. The menus [110], [120], [310], [362]-[368]
and [711] use the process unit selected in [321] and [322]
for the application, e.g. rpm, bar or m3/h. This makes it
possible to easily set up the AC drive for the required process
requirements, as well as for copying the range of a feedback
sensor to set up the Process Value Minimum and Maximum
in order to establish accurate actual process information.
Process Source [321]
Select the signal source for the process value that controls
the motor. The Process Source can be set to act as a function
of the process signal on AnIn F(AnIn), a function of the
motor speed F(Speed), a function of the shaft torque
F(Torque) or as a function of a process value from serial
communication F(Bus). The right function to select
depends on the characteristics and behaviour of the process.
If the selection Speed, Torque or Frequency is set, the AC
drive will use speed, torque or frequency as reference value.
Example
An axial fan is speed-controlled and there is no feedback
signal available. The process needs to be controlled within
fixed process values in “m
3
/hr” and a process read-out of the
air flow is needed. The characteristic of this fan is that the air
flow is linearly related to the actual speed. So by selecting
F(Speed) as the Process Source, the process can easily be
controlled.
The selection F(xx) indicates that a process unit and scaling
is needed, set in menus [322]-[328]. This makes it possible
to e.g. use pressure sensors to measure flow etc. If F(AnIn) is
selected, the source is automatically connected to the AnIn
which has Process Value as selected.

NOTE: The actual value in menu [310] is not copied, or
loaded from the control panel memory when Copy Set
[242], Copy to CP [244] or Load from CP [245] is
performed.
NOTE: If the MotPot function is used, the reference value
ramp times are according to the “Acc MotPot [333]” and
“Dec MotPot [334]” settings. Actual speed ramp will be
limited according to “Acc Time [331]” and
“Dec Time [332]”.
NOTE: Write access to this parameter is only allowed
when menu “Ref Control [214]” is set to Keyboard. When
Reference control is used, see section “10. Serial

NOTE: The motor control method depends on the
selection of drive mode [213], regardless of selected
