7.7.2 Drive behavior when STO is activated before rotational speed "0" is reached
NOTICE
Danger due to incorrect parameter settings
If the parameter Apply brake/activate DynaStop
®
in STO state is set to "1", (path:
Functions > Drive functions > FCB01 Output stage inhibit > Brake/DynaStop
®
), 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
DynaStop
®
function behaves as set in parameter Apply brake/DynaStop
®
in STO state
(Path: Functions > Drive functions > FCB01 Output stage inhibit > Brake/DynaStop

0 (no) 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.
