Input definition
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
Decrease motorpoti value

Value 13
Value 14
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.

Motorpoti
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).
