When the safe stop function is activated, the drive
generates an error message that is sent over the CAN bus
as message FF80. The motor coasts to a stop and must be
restarted manually.
The safe stop function can be used to stop the servo drive
in a hazardous situation. The standard methods for
stopping the drive should be used in normal operation
situations.
Possible implementation options can be found in
8.6 Application Examples.

The safe stop function turns off the supply voltage to the
semiconductor switches in the output power stage of the
drive. This prevents the generation of a voltage that causes
the motor to turn.
