Safety Integrated Functions
8.4 Safety Integrated Basic Functions
● 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).
● The cause of the fault must be remedied.
● The messages in the fault memory also need to be reset using the general
Note
If "Safe Torque Off" is selected and deselected again through one channel within the time
in p9650/p9850, the pulses are suppressed, but no messages are 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.
Restart after the "Safe Torque Off" function has been selected
1. Deselect the function.
2. Set drive enables.
3. Cancel "Switching On Inhibited" and switch the drive back on.
Status for "Safe Torque Off"
The status of the "Safe Torque Off" (STO) function is displayed via parameters r9772, r9872,
r9773, and r9774.
As an alternative, the status of the function can be displayed using the configurable
messages N01620 and N30620 (configured using p2118 and p2119).
Response time with the "Safe Torque Off" function
For the response times when the function is selected/deselected via input terminals, see the
table in "Response times".
