Setting SDI
The principle of operation of SDI is provided in section Safe Direction (SDI) (Page 42).

4.6.2.11
Defining the F-DI status
If you do not want to transfer the status of the fail-safe inputs via PROFIsafe, go straight to
the section Activate settings (Page 145).
If you want to transfer the status of the fail-safe digital inputs via PROFIsafe, you first have to
configure the relevant PROFIsafe telegram; see the section Configuring communication in
STEP 7 (telegram 900) (Page 102). In STARTER, you then have to specify which F-DI-
Status you want to transfer via PROFIsafe.

①
–
Enable the function
②
–
Delay time between selecting SDI and the active SDI:
The delay time must be greater than the time that the motor requires, when SDI is
selected, for braking with the maximum load from the maximum speed down to
standstill.
③
–
Tolerance for the permissible motion in the monitored direction (Unit: degree)
④
–
Reaction when the monitoring responds
See also section: STOP reactions (Page 192)
⑤
–
Behavior when the motor is switched off
Also see section: Switching off the motor when SDI is active (Page 44)
⑥ ⑦
–
If you interconnect the monitoring with speed limits p1051 and p1052, the
inverter limits the speed when SDI is active.
