5.2.3 Terminal module for control of "STO" and "SS1" for SINAMICS S150
Description
Option K82 (terminal module for controlling "Safe Torque Off" and "Safe Stop 1") is used to
control Safety Integrated Basic Functions in an electrically isolated fashion.
Note
Refer to the circuit diagrams enclosed for the interconnections of your device.
Note
The Safety functions must be activated prior to use via parameter assignment. An acceptance
test must be performed and an acceptance log must be created.
Option K82 is used to control the following Safety Integrated Basic Functions (terms and
definitions in accordance with IEC 61800-5-2):
• Safe Torque Off (STO)
• Safe Stop 1 (SS1) (time-controlled)
Note
The integrated safety functions, starting from the Safety Integrated (SI) input terminals of the
SINAMICS components (Control Unit, Motor Module), satisfy the requirements according to
IEC
61800-5-2, IEC 60204-1, ISO 13849-1 Category 3 for Performance Level (PL) d and
IEC
61508 SIL 2.
In combination with option K82, the requirements specified in IEC
61800-5-2, IEC 60204-
1 as
well as ISO 13849-1 Category 3 for Performance Level (PL) d and IEC 61508 SIL 2 are fulfilled.
In addition, most of the SINAMICS safety functions have been certified by independent
institutes. A list of currently certified components is available on request from your local
Siemens office or local sales office.
Recommended application
This option is used when the following requirements apply:
• Control is realized with electrical isolation in a voltage range 24 V DC/AC.
• Using non-shielded control lines which are longer than 30 m.
• The devices are deployed in plants dispersed over a wide area (no ideal equipotential
bonding).
