Drive behavior when STO is activated before rotational speed "0" is reached
NOTICE
Danger due to incorrect parameter settings
If the parameter

), the
DynaStop
®
function can be activated outside of the permitted operating range. This
can cause high torque loads / high motor currents, which may damage the drive unit
and the application.
Possible damage to property.
•
Use the factory settings or recommended settings.
If STO is activated before the motor has come to standstill (rotational speed = 0), the

The DynaStop

status remains unchanged when
STO is activated.
•
Depending on the application, the motor coasts
to a halt or even accelerates.
•
The stopping distance is not defined.
1 (yes)
DynaStop
®
is activated (not safety-related) when
STO is enabled.
•
In case DynaStop
®
is activated before the rota-
tional speed has reached "0", high torques/motor
currents can occur that may damage the drive
and the application.
•
Evaluate the possible consequences.
•
The stopping distance is not defined.
