Figure 7.6.12: Emergency Stop
a) the mains power has not been recovered during the stop procedure
b) the mains power has been recovered during the stop procedure
At the mains power loss, the drive will lead the motor to zero speed, with a ramp internally defined and depending by
the load inertia (not the one set).
If used, the braking device will provide the advantage to achieve as more as possible the specified
deceleration n fast stop time (F.208 - Dec time 4).
When reached the zero speed and exhausted the load energy, if the mains is not recovered, the DC link will
drop under the UV threshold.
This setting doesn't offer the possibility to lead back the motor to the original speed.
** Once at zero speed if the mains power is recovered, to restart the motor will be necessary to release the
RUN command and then apply it again.
The status of the "Emergency Stop" function, is available on digital output, programmed as "Emg Stop"
(programming code: 49).
