Parameters 225
22.74 Motor
potentiometer down
source
Selects the source of motor potentiometer down signal.
0 = No change
1 = Decrease motor potentiometer value. (If both the up and
down sources are on, the potentiometer value will not
change.)
Note: Motor potentiometer function up/down source control
speed or frequency from zero to maximum speed or
frequency. The running direction can be changed with
parameter 20.04 Ext1 in2 source. See the figure in section
Motor potentiometer macro on page 111. For the selections,
see parameter 22.73 Motor potentiometer up source.
Not used
22.76 Motor
potentiometer min
value
Defines the minimum value of the motor potentiometer.
Note: If vector control mode is used, value of this parameter
must be changed.

-32768.00…
32767.00
Motor potentiometer minimum. 1 = 1
22.77 Motor
potentiometer max
value
Defines the maximum value of the motor potentiometer.
Note: If vector control mode is used, value of this parameter
must be changed.
50.00
-32768.00…
32767.00

potentiometer is configured using parameters 22.71…22.74.)
This parameter is read-only.
0.00
-32768.00…
32767.00
Value of motor potentiometer. 1 = 1
22.86 Speed reference
act 6
Displays the value of the speed reference (EXT1 or EXT2)
that has been selected by 19.11 Ext1/Ext2 selection. See
diagram at 22.11 Ext1 speed ref1 or the control chain diagram
on page 486.
This parameter is read-only.
