Simultaneity And Tolerance Time Of The Two Monitoring Channels - Siemens SINUMERIK MC Commissioning Manual

Controlling safety functions integrated in the drive
5.6 Control via terminals on the Control Unit and Motor/Power Module
Note
Parameterization of the grouping
The grouping must be set the same in both monitoring channels.
The assignment is checked during the test for the switch-off signal paths. The operator selects
the STO safety function for each group. The check is drive-specific.
Example: Terminal groups
It must be possible to select/deselect safety function STO separately for group 1 (drives 1 and
2) and group 2 (drives 3 and 4).
For this purpose, the same grouping for STO must be realized both for the Control Unit and the
Motor Modules.

Simultaneity and tolerance time of the two monitoring channels

The "Safe Torque Off" (STO) safety function must be selected/deselected simultaneously in
both monitoring channels using the input terminals, and is only effective for the associated
drive.
● 1 signal: Deselecting the function
● 0 signal: Selecting the function
