(5) Second acceleration/deceleration time
switching frequency [Pr. 147]
[Pr. 44] and [Pr. 45] are valid when the output
frequency reaches or exceeds the setting of [Pr.
147]. When RT signal is OFF, automatic
switching of the acceleration/deceleration time is
available with [Pr. 147]. Even when automatic
switching by the RT signal occurs at the
frequency less than [Pr. 147] setting, the
acceleration/deceleration time switches to the
second acceleration/deceleration time.

A700
When the third function selection signal (X9)
turns ON, the acceleration/deceleration time set
in [Pr. 7, 8] is ignored and the acceleration/
deceleration time set in [Pr. 110] is active. In this
case, the acceleration time is equal to the
deceleration time. Set "9999" in [Pr. 110] to make
this function invalid.
When both the RT and X9 signals are ON, [Pr.
100, 111] are valid.
When the setting value of [Pr. 110] is 0.03s or
less, acceleration/deceleration time is 0.04s
(when V/F control, Advanced magnetic flux
vector control, or Simple magnetic flux vector
control). At that time, [Pr. 20] should be set to
"120Hz" or less.

(7) Third deceleration time [Pr. 111]
When the third function selection signal (X9)
turns ON, the acceleration/deceleration time
changes to the value set in [Pr. 110]. In this case,
the acceleration time equals to the deceleration
time. In this case, the acceleration time is equal
to the deceleration time.
To set the acceleration time and deceleration
time separately, set the third deceleration time in
[Pr. 111] and the third acceleration time in [Pr.
110]. Setting of 9999 (initial value) in [Pr. 111]
causes the third deceleration time to be the
value set in [Pr. 111], making the acceleration
and deceleration times equal.
When both the RT and X9 signals are ON, [Pr.
100, 111] are valid.
When the setting value of [Pr. 111] is 0.03s or
less, deceleration time is 0.04s (when V/F
control, Advanced magnetic flux vector control,
or Simple magnetic flux vector control). At that
time, [Pr. 20] should be set to "120Hz" or less.
(8) Acceleration/deceleration time for Jog
operation [Pr. 16]
Allows the acceleration/deceleration time to be
set for Jog operation in the PU or External
operation mode.
acceleration time is equal to the deceleration
time. For details of the operation procedure,
refer to page 215.
In the External operation mode, tuning Jog
operation selection signal (JOG) enables the
Jog operation.
The setting of the acceleration/deceleration time
is as described in (1) and (2) Acceleration and
deceleration times [Pr. 7, 8]. Set acceleration/
deceleration time until the [Pr. 20 Acceleration/
deceleration reference frequency] is reached.
