9.2.6
Acceleration/ deceleration 2 (2CH)
(1) In case of changing by intelligent input terminal, assign 09(2CH) to an Intelligent input
terminal.
(2) By setting this function, it is possible to change the rate of acceleration and deceleration.
(3) As methods to change the rate of acceleration and deceleration, you can select the method of
changing by intelligent input terminal and the method of automatic changing by optional
frequency.
(4) While the state of a setting terminal [2CH]-[CM1] is ON, the inverter runs in 2 step
acceleration/deceleration time.
If the terminal is set OFF, return to the initial acceleration/deceleration time (acceleration
/deceleration time 1).
(5) When
Acceleration/Deceleration
select(A007) is set to 0, this function is valid.
(6) When A007 is set to 1, the frequency is switched by the frequency setting value of A010, A011.

terminal 1(I001)
9.2.7
Three-Stages acceleration/deceleration (3CH)
(1) In case of changing by intelligent input terminal, assign 10(3CH) to an Intelligent input
terminal.
By setting this function, it is possible to change the rate of acceleration and deceleration.
(2) As methods to change the rate of acceleration and deceleration, you can select the method of
changing by intelligent input terminal and the method of automatic changing by optional
frequency.
(3) While the state of a setting terminal [3CH]-[CM1] is ON, the inverter runs in 3 step
acceleration/deceleration time.
If the terminal is set OFF, return to the initial acceleration/deceleration time (acceleration/
deceleration time 1).
(4) When Acceleration/Deceleration select (A012) is set to 0, this function is valid.
When A012 is set to 1, the frequency is switched by the frequency setting value of A015,
A016.
