Control via F-DI (TM54F or onboard terminals)
1. Using parameters p10009, parameterize an F-DI, with which you can select/deselect the
internal retract logic function.
2. Parameterize two F-DIs for the selection/deselection of the SDI positive and SDI negative
functions in an independent acceptance test.
3. Proceed as follows for an SLP limit violation:
– Switch the signal at the F-DI "retract" from 0 to 1 (the signal edge is evaluated). The
– Safe acknowledgment of the limit violation
– Move the drive into the range that has been enabled using the appropriate setpoint
– Switch the signal at the F-DI "retract" from 1 to 0 (the signal edge is evaluated): As a
