Source selection (see Terms and abbreviations
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.)
For the selections, see parameter
up source.
Defines the change rate of the motor potentiometer. This
parameter specifies the time required for the motor
potentiometer to change from minimum (22.76) to maximum
(22.77). The same change rate applies in both directions.
Motor potentiometer change time.
Defines the minimum value of the motor potentiometer.
Note: If vector control mode is used, value of this parameter
must be changed.
Motor potentiometer minimum.
Defines the maximum value of the motor potentiometer.
Note: If vector control mode is used, value of this parameter
must be changed.
Motor potentiometer maximum.
The output of the motor potentiometer function. (The motor
potentiometer is configured using parameters 22.71...22.74.)
This parameter is read-only.
Value of motor potentiometer.
Displays the value of the speed reference (Ext1 or Ext2) that
has been selected by 19.11 Ext1/Ext2
at 22.11 Ext1 speed ref1
420.
This parameter is read-only.
Speed reference after additive 2.
Displays the value of speed reference before application of
critical speeds. See the control chain diagram on page 423.
The value is received from
unless overridden by
• any constant speed
• a jogging reference
• network control reference
• control panel reference
• safe speed reference.
This parameter is read-only.
