Deceleration time

through
0.0s to
300.0s
20.0s
This parameter is valid only in the
"decelerate to stop" (F9‑59 is set
to 2) mode.
When the bus voltage is below
F9‑62, the AC drive decelerates to
stop. The deceleration time is
determined by this parameter
instead of F0‑18.
3.7.10Fault Reset
In the case of an undervoltage fault (E09.00), the AC drive resets automatically when
the bus voltage restores to the normal range. This reset is not counted in the number
of fault auto reset times. In the case of a short circuit to ground (E23.00), the AC drive
AC does not support automatic or manual reset, and you need to reset the AC drive by
powering it off and then powering it on again. Fault protection action selection is
required when the number of fault auto reset times is reached.

F9‑09 Fault auto rehset times 0 0 to 20
This parameter is used to set the number of automatic
resets for the AC drive if the fault protection action is set
to automatic reset. If the fault persists after the
specified number of automatic resets, the AC drive
retains the fault state.
F9‑10
DO action during auto
fault reset
1
0: Not act
1: Act
If the AC drive is enabled to reset automatically upon
faults, F9‑10 can be used to determine whether the DO
terminal (function 2) acts during an automatic reset.
F9‑11
Auto fault reset
interval
1.0s 0.1s to 100.0s
This parameter is used to set the delay of auto reset
after the AC drive detects a fault.
3.7.11Fault Protection Action Selection
Four fault protection actions are defined for the AC drive: coast to stop, decelerate to
stop, warning, and canceled, listed in descending order of fault severity.
When the fault protection action is set to "warning", the operating panel displays Axx.
xx upon fault occurrence, for example,
.
When the fault protection action is set to "canceled", the operating panel does not
display any message upon fault occurrence. Exercise caution when setting this action.
