NOTICE
It is not possible to activate the control via safety terminals and PROFIsafe at the same
time.
● STO via on-board terminals (F-DI 0, Basic Functions):
● STO via on-board terminals (with "Extended Functions" option):
● STO via PROFIsafe (with "Extended Functions" option):
● STO via PROFIsafe or on-board terminals (F-DI 0) (with "Extended Functions" option):
Selecting/deselecting "Safe Torque Off"
The following occurs when "Safe Torque Off" is selected:
● Each monitoring channel triggers safe pulse suppression via its switch-off signal path.
● A motor holding brake is applied (if connected and configured).
The following occurs when "Safe Torque Off" is de-selected:
● Each monitoring channel cancels safe pulse suppression via its switch-off signal path.
● The safety prompt "Apply motor holding brake" is canceled.
● Any pending STOP F or STOP A commands are canceled (see r9772/r9872).

Note
If "Safe Torque Off" is de-selected and selected again through one channel within the
time in p9650/p9850, the pulses are canceled but a signal is not output.
If you want a message to be displayed in this case, however, you have to reconfigure
N01620/N30620 via p2118 and p2119 as an alarm or fault.
