WARNING
If a negative reference value is set, the drive is decelerated with command "Percentage
motorpoti up". The reference value is changed in positive direction.
Limit
The reference values are limited via parameters

"Motorpotentiometer via digital inputs" as reference value
The function "Motorpotentiometer via digital inputs" can be selected via the following parameters:
−
Reference Percentage Source 1
−
Reference Percentage Source 2
See chapter 7.5.2 "Reference percentage channel".
Chapter 7.6.6.1 "List of control signals" contains a table summarizing the available signal sources for

Addition of reference values
If the reference value of the motorpoti function is added to another reference value, (via

Percentage Source 1
− If the value of
Maximum Reference Percentage
increased, the output value of the motorpoti function is reduced. It is reduced, so that the sum of
both reference values is equal to the maximum reference percentage value.
− If the value of
Minimum Reference Percentage
reduced, the output value of the motorpoti function is increased. It is increased, so that the sum of
both reference values is equal to the minimum reference percentage value.
− In the settings for
Operation Mode
reversal of direction of rotation can be shifted by the output value of the motorpoti function. The
drive changes its direction of rotation if the total of the two reference values changes the sign.
