Parameters 153
22.56 Critical speed 3 low
Defines the low limit for critical speed range 3.
Note: This value must be less than or equal to the
value of parameter 22.57 .

Low limit for critical speed 3. See par.
46.01
22.57 Critical speed 3 high
Defines the high limit for critical speed range 3.
Note: This value must be greater than or equal to the
value of parameter
22.56
.

Determines when parameters
22.73 Motor
potentiometer up source
and
22.74 Motor
potentiometer down source
may change parameter
22.80 Motor potentiometer ref act
.
Selected
Not used Motor potentiometer Up/Down sources (
22.73
and
22.74
) are disabled.
0

22.71 Motor potentiometer
function
Activates and selects the mode of the motor
potentiometer.
See section
Speed control performance figures
in
chapter Program features .
Disabled
Disabled Motor potentiometer is disabled and its value set to
0.
0
Enabled (init at stop/
power-up)
When enabled, the motor potentiometer first adopts
the value defined by parameter
22.72
. The value can
then be adjusted from the up and down sources
defined by parameters
22.73
and
22.74
.
A power cycle will reset the motor potentiometer to
the predefined initial value (
22.72
).
1
Enabled (resume
always)
As
Enabled (init at stop/ power-up)
, but the motor
potentiometer value is retained over a power cycle.
2
Enabled (init to actual) Whenever another reference source is selected, the
value of the motor potentiometer follows that
reference. After the source of reference returns to the
motor potentiometer, its value can again be changed
by the up and down sources (defined by
22.73
and
22.74
).
3
Enabled (resume/init
to Actual)
As
Enabled (init to actual)
, but the motor
potentiometer ref act value is retained over power
cycle.
4
22.72 Motor potentiometer
initial value
Defines an initial value (starting point) for the motor
potentiometer. See the selections of parameter 22.71 .
