Material damages and personal injuries by the drop of a hanging axis
It is not allowed to use the STO with a hanging axis because the axis may drop. Unexpected drop of the hanging axis may
cause material damages and personal injuries.
Note
Using the STO function
The STO1, STO+ and STO2 are short connected at the factory setting.
When the STO function is to be used, you must remove the
short-circuit stick before connecting the STO interfaces. The
safety function of the servo drive is SIL 2 (EN61800
-5-2). If you do not need to use it any more, you must reinsert the short-
circuit stick; otherwise, the motor will not run.
mation about the STO function, refer to chapter "Safety Integrated basic functions" of SINAMICS V90,
-1FL6 Operating Instructions.
Assembling the 24 V power supply and STO cable terminals
The procedure of assembling a 24 V power cable terminal or an STO cable terminal is the same as that for a power cable
terminal on the drive side of the V90 PN 200 V servo drives.
For more information, see the SINAMICS V90, SIMOTICS S-1FL6 Operating Instructions.
