Control of the Basic Functions via a safe input terminal pair

8.6.2.1

Control via terminals on the Control Unit and the power unit

Features
● Dual-channel structure via two input terminals as a safe input terminal pair
● Input filter for test signals with a dark period < 1 ms
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 operated simultaneously, 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 and is only effective for the associated drive.
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 (Control Unit)
● SI SGE changeover, tolerance time (Power Module)
If the "Safe Torque Off" function is not selected/deselected within the tolerance time, this is
detected by the crosswise comparison, 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.
8.6.3

Control of the Safety Integrated Extended Functions using safe input terminals

General information
The Control Unit CU305 includes 6 digital inputs, which can be used as 3 safe input terminal
pairs (F-DI) for the control of the Extended Functions.
Furthermore, the CU305 can be extended by exactly one digital output as a safe output
terminal pair (F-DO) and usable for the Extended Functions.
● F-DI 0 = DI16/DI17
● F-DI 1 = DI18/DI19
● F-DI 2 = DI20/DI21
● F-DO 0 = DO16+/DO16-
