Safety Integrated
Overview
5
■
Function
(continued)
The safety functions are listed below with criteria for actual value sensing:
1)
The use of this safety function without encoder is permitted for
asynchronous (induction) motors or synchronous motors of the SIEMOSYN
series.
2)
Only for the transmission of relative position values. An encoder is required
to transmit absolute position values.
Licensing
The Safety Integrated Basic Functions do not require a license.
In the case of Safety Integrated Extended Functions, however, a
license is required for each axis equipped with safety functions.
It is of no consequence here which safety functions are used and
how many.
The required licenses can be optionally ordered with the
CompactFlash card.
For article numbers of the CompactFlash cards, see chapter
SIMOTION D – Drive-based or the Catalog D 21.4 SINAMICS
S120 and SIMOTICS – Motion Control Drives.
