WARNING!
The functions described in this manual do not disconnect the voltage of the main
and auxiliary circuits from the drive. Do not do work on the drive, motor cable or
motor when they are energized. Before you start the work, do the steps in section
Electrical safety precautions (page 11).
WARNING!
If a short-circuit occurs in the output stage of the drive, the STO function does not
prevent the intermediate DC current from flowing through and heating up the motor.
The system integrator must take this into account when planning the protection of
the installation.
