The first step is the definition of two inputs with which the the motor potentiometer
can be increased and decreased. Depending on the selected inputs two of the
parameters di.3...di.12 are assigned with the value 14 and 15.
Increase motorpoti value
Value 13
The potentiometer value is decreased, ff the inputs potentiometer value are triggered
at the same time.
With SP.26 some basic operational modes of the motor potentiometer are defined.
The parameter is bit-oriented.

x x x 0 Motor potentiometer can be programmed differently in all parameter
sets.
x x x 1 Motor potentiometer is not set-programmable
x x 0 x After a power-on reset the last potentiometer value is adjusted.
x x 1 x After a power-on reset the potentiometer value is set to 0 %.
0 0 x x Rise time of 0...100% of motor potentiometer 16 s
0 1 x x Rise time of 0...100% of motor potentiometer 33 s
1 0 x x Rise time of 0...100% of motor potentiometer 66 s
1 1 x x Rise time of 0...100% depending on parameter SP.27
0 0 0 0 = 0 (Default value)
With this parameter a time is defined which the motor potentiometer needs to drive
from 0...100% zu fahren. The adjusted time takes effect when a value of > 12 is
adjusted in parameter SP.26. The time is adjustable in a range of 0,00...300,00 s
(Factory setting 128s).(From software version 1.3)
The absolute setpoint limits of the motor potentiometer (-100%...0...+100%) are limited
by the minimum/maximum frequencies (SP.4 and 5 or SP.6 and 7) (see Fig. 6.8.4).
To set the setpoint value by way of the motor potentiometer parameter SP.0 (setpoint
source) must be adjusted accordingly.
