13.10 Motor Potentiometer
The motor potentiometer is used for controlling the motor speed using
• digital control signals (Function Motorpoti MP) or
• the keys of the KP 500 control unit (Function Motorpoti KP)
The following functions are assigned to the Up/Down control commands:
Activation
Motorpoti (MP) Motorpoti (KP) Function
Up Down Up Down
0 0 – –
Output signal does not change.
1 0
â–²
–
Output value rises
at set ramp.
0 1 –
â–¼
Output value drops
at set ramp.
1 1
â–² + â–¼
Output value is reset
to initial value.
0 = contact open 1 = contact closed
â–² â–¼ = arrow keys at KP 500 control unit
The motor potentiometer function as well as its assignment to other reference value
sources can be selected in the corresponding reference value channels via parameters
Reference Frequency Source 475 or Reference Percentage Source 476.
Refer to Chapters "Frequency Reference Channel" and "Reference percentage chan-
nel" for the possible reference value source assignments.
The availability of the functions "Motorpoti (MP)" and "Motorpoti (KP)" varies in the
different reference value channels:
Reference value channel

Reference Percent-
age Source

Motorpoti (MP) X X
Motorpoti (KP) X 0
X = Function available 0 = Function not available
Depending on the active reference value channel, the function is assigned to a digital
signal via parameters
Frequency Motorpoti Up 62, Frequency Motorpot. Down 63 or
Percent Motorpo. Up 72, Percent Motorpoti Down 73.
Refer to Chapter "Digital Inputs" for a list of the available digital signals.
