POUS indication delay (see parameter POUS.13): An additional security delay. The POUS completed
indication (parameter POUS.22) becomes active after this delay. A
1. The user stops the motor(s).
2. After the motor(s) have stopped, the user switches the POUS switch off (open). The
FSO module activates the inverter unit STO function.
Note: If the user activates the POUS function when the motor is running, the FSO
module activates the inverter unit STO function, the motor(s) coasts to a stop and the
FSO module generates a fault.
3. After time A has elapsed, the POUS indication lamp turns on (POUS completed
indication).
4. The user switches the POUS switch on (closed). The FSO module deactivates the
inverter unit STO function and turns off the POUS indication lamp. The user can start
the motor(s) again.
Note: In this case, automatic acknowledgement of the POUS function is selected
(parameter POUS.02).
5. The user restarts the motor(s).
￭ Operation principle diagram
This diagram shows the connections of two FSO modules in a network (without the safety
encoder interface). The figure shows a simplified operation principle. For a more detailed
description, see the circuit diagrams delivered with the drive.
