15.10 Motor potentiometer
Via the motor potentiometer function, the motor speed is controlled via
 digital control signals (function Motorpoti MP) or via
 the keys of the control unit KP°500 (Function Motorpoti KP).
The control up/down commands are assigned the following functions:

The motor potentiometer function and its link to other reference value sources can be selected in
the corresponding reference value channels with parameters
Reference Frequency Source
475 or
Reference Percentage Source
476 .
For a description of the possible links of the reference value sources, refer to chapters "Reference
Values", "Reference Values" and "Reference Values".
Availability of functions "Motorpoti (MP)" and "Motorpoti (KP)" differs in the individual reference
value channels:

For a summary of available digital signals, refer to chapter "Digital Inputs".
The
Operation Mode
474 of the motor potentiometer function defines the behavior of the function
at various operating points of the frequency inverter.
Operation Mode 474 Function
0 - Not Latching
In the operation mode motor potentiometer Not Latching , the drive
goes to the set minimum reference value at each start.
1 - Latching
In the operation mode Latching the motor goes to the reference value
selected before the switch-off at the start. The reference value is also
stored when the device is switched off.
2 - Taking Over
The operation mode Motorpoti Taking Over is to be used for the data
set change-over of the reference value channel. The current reference
value is used when the motorpoti function is activated.
3 - Taking Over
and Latching
This operation mode combines the behavior in operation mode 1 and 2.
