Safety functions 133
Step Description
1
The user stops the motor.
2
The user activates the POUS function. The FSO activates the drive STO function and
starts a counter for time A. The POUS active indication (parameter
) and the
STO output indication (parameter
) become active.
Note
: If the user activates the POUS function when the motor is running, the FSO
activates the drive STO function, generates a fault (7A97) and the motor coasts to a
stop.
3
After time A has elapsed, the POUS completed indication becomes active (parameter
Note
: Connect the POUS indication lamp to this indication signal.
4
The user removes the POUS request. The POUS completed indication is deactivated.
The acknowledgement becomes allowed.
Note
: If the user activates the POUS request again before the POUS function has been
acknowledged, the counter for time A is restarted and the POUS completed indication
is activated after this delay.
5
The user acknowledges the POUS function. The POUS active indication goes off. The
FSO deactivates the drive STO function and the user can restart the motor.
Note
: If automatic acknowledgement is used, this happens already when the POUS
request is removed (step 4).
6
The user starts the motor.
