will be set. H5-04 = 0 selects Ramp to Stop. The deceleration time or the slope of the ramp is determined by the setting of
drive parameter C1-02. H5-04 = 1 selects Coast to Stop. The drive does not attempt to control the rate of deceleration. H5-04
= 2 selects Fast Stop. The deceleration time is determined by the setting of drive parameter C1-09.
Note:
\The behavior of the drive at cable loss is controlled by parameter H5-04. This drive parameter works with the points as described in the
table above to determine how the drive will respond to a cable loss. If the cable loss fault is disabled, the drive will continue in its last state,
if running the drive will continue to run at the last commanded frequency.

Stop with Fault (CE)
In this mode, CBL LOSS TMR (POINT 92) is set to the desired interval, COMM FLT ENA (POINT 90) or is set to “ON”
and either CMD RUN.FWD (Point 22) or CMD RUN.REV (Point 24) is also set to “ON”. If the time between messages
exceeds the timeout interval, a “CE” fault is declared and the drive stops. The stopping method is controlled by the setting of
H5-04 and is described above. CBL LOSS FRQ (POINT 91) is ignored.
