7.4.4 Example: Change-over from AI1 setpoint to MOP setpoint
The "Acvate MOP setpoint" funcon enables a setpoint change-over to the motor poten-
ometer during operaon.
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^ 131
•
no jog operaon is acve ("Jog foward (CW)" and "Jog reverse (CCW)" funcons).
Example for operang mode
•
The analog input 1 is set as standard setpoint source.
•
Switch S1 starts the motor in forward direcon of rotaon. Switch S1 in the inial posion
stops the motor again.
•
Switch S2 acvates the motor potenometer as setpoint source. The MOP setpoint can
then be increased via buon S3 and reduced via buon S4. If both buons are pressed at
the same me, the MOP setpoint remains unchanged.
•
Switch S5 switches the direcon of rotaon.
