Simultaneity And Tolerance Time Of The Two Monitoring Channels_Basic_Functions - Siemens SINAMICS S120 Function Manual

Safety Integrated Basic Functions
11.8 Controlling via terminals on the Control Unit and Motor/Power Module
Example: Terminal groups
It must be possible to select/deselect "Safe Torque Off" separately for group 1 (drives 1 and 2)
and group 2 (drives 3 and 4). For this purpose, the same grouping for "Safe Torque Off" must
be realized both for the Control Unit and the Motor Modules.
Figure 11-3 Example: Grouping terminals with Motor Modules Booksize and CU320-2
Information on the parallel connection of Chassis format Motor Modules
When Chassis format Motor Modules are connected in parallel, a safe AND element is created
on the parallel drive object. The number of indexes in p9620 corresponds to the number of
parallel Chassis components in p0120.

Simultaneity and tolerance time of the two monitoring channels_Basic_Functions

The monitoring functions must be selected/deselected simultaneously in both monitoring
channels via the input terminals and only have an effect on the associated drive.
● 1 signal: Deselecting the function
● 0 signal: Selecting the function
The time delay that is unavoidable due to mechanical switching, for example, can be adapted
via parameters. The tolerance time, within which selection/deselection of the two monitoring
channels must occur if they are to be considered "simultaneous," is set in the following
parameters:
● p9650 (Basic Functions)
● p10002 (Extended / Advanced Functions)
