2.8.2 TÜV certification
The RASP5 speed controllers with STO function, which have a TÜV logo on
the nameplate, include an STO function in accordance with the standards
listed here:
This safety function corresponds to uncontrolled stopping as defined in
IEC60204-1, Stop Category 0.

CAUTION
When used in conjunction with permanent magnet motors and
in the unlikely event of multiple output semiconductors (IGBTs)
failing, having the STO function activated may result in a motor
shaft rotational movement of 180 degrees/p = Number of motor
pole pairs).

DANGER
The STO function is an electronic mechanism that does not
provide sufficient protection against electric shock. Additional
potential isolation measures may be accordingly required (e. g.,
switch-disconnecter).

DANGER
Only the STO function of the drive can be used as a safety func-
tion of a machine.
None of the other functions of the drive can be used to execute
a safety function.
