Functional features
● Parameters r9720.12/r9720.13 display whether the SDI function is selected.
● Parameters rr9722.12/r9722.13 display whether the SDI function is active.
● Parameters p9364/p9564 are used to set the tolerance within which a movement in a
non-enabled (non-safe) direction is tolerated.
● Parameters p9366/p9566 define the stop response in the case of a fault.
● For control via terminals, parameters p10030/p10130 are used to define the terminals for
SDI.
● Parameter p10042 is used to define whether the SDI status in the status display of the
F-DO is taken into account.
● If "SDI positive" is selected, the following value is set automatically:
– r9733[1] = 0 (setpoint limitation negative)
● If "SDI "negative" is selected, the following value is set automatically:
– r9733[0] = 0 (setpoint limitation positive)
● The absolute setpoint speed limit is available in r9733[2].
