Two Stage Acceleration and Deceleration
When terminal [2CH] is turned ON, the inverter
changes the rate of acceleration and
deceleration from the initial settings ( and
) 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
( acceleration time 1, and 
deceleration time 1). Use  (acceleration
time 2) and  (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 () to acceleration 2 ().

Deceleration
ON
Frequency output uses 2nd-stage acceleration and
deceleration values
OFF
Frequency output uses the initial acceleration 1 and
deceleration 1 values
Valid for inputs:
~
Example (requires input configuration see page 66):
See I/O specs on page 23, 24.
Required settings
, , =
Notes:
 Function  selects the method for second
stage acceleration. It must be set =  to select
the input terminal method in order for the [2CH]
terminal assignment to operate.
