11.3.6 Motor potenometer setpoint source
The "Mot
or potenometer" funcon can be used as an alternave setpoint control that is
controlled via two funcons: "Motor potenometer up" and "Motor potenometer down".
The "Setpoint = Motor potenometer" funcon enables a setpoint change-over to the motor
potenometer.
Precondions
A setpoint change-over to the motor potenometer is only eected if
•
no setpoint source with a higher priority has been selected. 4Priority of the setpoint sour-
ces^ 193
•
no jog operaon is acve ("Foward jog (CW)" and "Backward jog (CCW)" funcons).
Details
If the motor potenometer is acve as setpoint source, the setpoint generated by this func-
on ("MOP value") can be changed according to the truth table via the triggers assigned to
the two "Motor potenometer up" and "Motor potenometer down" funcons:
Motor potenometer
up
Motor potenometer
down
R
esponse of the funcon
FALSE FALSE Last MOP value is maintained.
TRUE FALSE MOP value is increased to a maximum of the upper range limit with acceleraon me 2.
FALSE TRUE MOP value is decreased to a maximum of the lower range limit with deceleraon me 2.
TRUE TRUE Last MOP value is maintained.
Starng performance
•
In the default seng, the last MOP value is used as inial v
alue. As an alternave, an adjust-
able inial value or the minimum value can be used for starng. The starng performance
can be selected in 0x4003 (PAR 413).
•
The last MOP v
alue is sll provided aer switching the mains voltage o and on again.

Assignment of a trigger for the "Motor potenometer up" funcon.
Trigger = TRUE: setpoint generated by the "Motor potenometer" func-
on ("MOP value") is maximally increased to the upper range limit with
acceleraon me 2.
Trigger = FALSE: last MOP value is maintained.
Notes:
•
If the "Motor potenometer up" and "Motor potenometer down"
funcons are acve at the same me, the last MOP value is main-
tained.
•
Acceleraon me 2 can be set in 0x2919 (PAR 222).
