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).

Function Name State Description
ON Frequency output uses 2nd-stage acceleration and

OFF Frequency output uses the initial acceleration 1
and deceleration 1 values
Valid for inputs: C001~C005
Required settings A092, A093, A094=00
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.
