Activation of safety functions
The Safety Integrated functions are fully integrated in the
drive system. They can be activated as follows:
• Via safety-related inputs on the Control Unit and the
power unit (Basic Functions) or using Option K82
“Terminal interface for Safety Integrated functions
STO and SS1” which provides a convenient customer
interface for enclosed drives
• Via safety-related inputs on the TM54F Terminal Module
(option K87) (Extended Functions)
•
Via PROFIBUS or PROFINET with the PROFIsafe profile
(Basic and Extended Functions)
The TM54F Terminal Module is not required when functions
are selected via PROFIsafe.
As an alternative to controlling via terminals and/or
PROFIsafe, there is also the option to parameterize some
safety functions without selection. In this mode, after
parameterization and a POWER ON, these functions are
permanently selected.
Example:
“SLS without selection” can be used, for example, to monitor
the maximum speed to prevent the drive from exceeding a
mechanical speed limit. For this purpose, using the “without
selection” function, an F-DI does not have to be used.
PROFIsafe
SINAMICS drives support the PROFIsafe profile based on
PROFIBUS as well as on PROFINET. PROFIsafe is an open
communication standard that facilitates standard and
safety-relevant communication along one communication
path (hardwired or wireless). A second, separate bus system
is therefore not required. The telegrams that are sent are
continually monitored to ensure reliable communication.
Potential errors such as lost or repeated telegrams, or
telegrams received in the wrong sequence, are prevented
by the consecutive numbering of safety-related telegrams,
by monitoring of telegrams to ensure that they are received
within a defined time period, and by transmission of an
identifier for the telegram sender/receiver. A CRC (cyclic
redundancy check) data security mechanism is also used.
Licensing
The Safety Integrated Basic Functions do not require a license.
The Safety Integrated Extended Functions require a license
(option
K01
). It is irrelevant which safety functions are used
and how many.
