Supported functions

The functions listed here are in conformance with the IEC 61508, SIL2 standard, in
the operating mode with a high demand, Category 3 and Performance Level d acc.
to ISO 13849--1 (2006) as well as IEC 61800--5--2.
The following Safety Integrated functions are available (SI functions):
S Safety Integrated Basic Functions
These functions are part of the standard scope of the drive and can be used
without any additional license:
-- Safe Torque Off (STO)
STO is a safety function that prevents the drive from restarting unexpec-
tedly, in accordance with EN 60204--1, Section 5.4.
-- Safe Stop 1 (SS1, time controlled)
The SS1 function is based on the "Safe Torque Off" function. This means
that a Category 1 stop in accordance with EN 60204--1 can be implemented.
-- Safe Brake Control (SBC)
The SBC function permits the safe control of a holding brake.
SBC is only supported by Power/Motor Modules in the chassis format with
order number ...3 or higher. For this function, Power Modules in the block-
size format also require a Safe Brake Relay.

SINAMICS HLA and Safety Integrated
SINAMICS HLA supports the following Safety Integrated functions of the
CU320--2:
S Basic Functions
These functions are part of the standard scope of the drive and can be used
without requiring an additional license. Are always available. These functions do
not require an encoder and/or do not place any special requirements on the en-
coder used.
-- Safe Torque Off (STO)
Safe Torque Off is a safety function in accordance with EN 60204--1 that
prevents the drive from restarting unexpectedly. STO prevents the supply of
power to the valve, which can produce a force. It is equivalent to stop
Category 0.
-- Safe Stop 1 (SS1, time controlled)
Safe Stop 1 is based on the "Safe Torque Off" function. This means that a
Category 1 stop in accordance with EN 60204--1 can be implemented.
The Safety Integrated functions of SINAMICS HLA can be commissioned using the
expert list.
