Control of the Basic Functions via a safe input terminal pair

Features
● Only for the STO, SS1 (time-controlled), and SBC functions
● Dual-channel structure via two input terminals as a safe input terminal pair
● A debounce function can be applied to the terminals of the Control Unit and the Power
Overview of the safety function terminals for SINAMICS S110
The digital input terminals DI16 and DI17 are defined as F-DI0 for the control of the Basic
Functions, if these are enabled (see diagram "Internal connection of DI/DO of the CU305
with safety function"). Both terminals are processed securely by different signal evaluators in
two channels. Both terminals must be activated within a parameterized tolerance time,
otherwise a fault will be issued.
Simultaneity and tolerance time of the two monitoring channels
The "Safe Torque Off" function must be selected/deselected simultaneously in both
monitoring channels using the input terminals.
1 signal: Deselecting the function
0 signal: Selecting the function
"Simultaneously" means:
The changeover must be complete in both monitoring channels within the parameterized
tolerance time.
● p9650 SI SGE changeover tolerance time (CPU 1)
● p9850 SI SGE changeover tolerance time (CPU 2)
Note
To avoid incorrect triggering of fault messages, on these inputs the tolerance time must
always be set to be smaller than the shortest time between two switching events
(ON/OFF, OFF/ON).
If the STO is not selected by both channels within the tolerance time, this is detected by the
data cross-check and fault F01611 or F30611 (STOP F) is output. In this case, the pulses
have already been canceled as a result of the selection of "Safe Torque Off" on one channel.
414
Module to prevent incorrect trips due to signal disturbances or asymmetrical test signals.
Parameters p9651 and p9851 are used to set filter times.
