Two Stage Acceleration and Deceleration
When terminal
[
2CH
]
is turned ON, the
inverter changes the rate of acceleration and
deceleration from the initial settings
(
F002
and F003
)
to use the second set of
acceleration/ deceleration values. When the
terminal is turned OFF, the inverter is
returned to the original acceleration and
deceleration time
(
F002 acceleration time 1,
and F003 deceleration time 1
)
. Use A092
(
acceleration time 2
)
and A0093
(
deceleration
time 2
)
to set the second stage acceleration
and deceleration times.
In the graph shown above, the
[
2CH
]
becomes active during the initial acceleration.
This causes the inverter to switch from using acceleration 1
(
F002
)
to acceleration 2
(
A092
)
.

Notes
:
x
Function A094 selects the method for second
stage acceleration. It must be set = 00 to select
the input terminal method in order for the
[
2CH
]
terminal assignment to operate.
