Two-stage Acceleration and Deceleration
When terminal [2CH] is turned ON, the
inverter changes the rate of acceleration and
deceleration from the initial settings (F_02
and F_03) to use the second set of accelera-
tion/deceleration values. When the terminal is
turned OFF, the inverter is returned to the
original acceleration and deceleration time
(F_02 acceleration time 1, and F_03 decelera-
tion time 1). Use A_92 (acceleration time 2)
and A_93 (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 (F_02) to acceleration 2 (A_92).

Description
09 2CH 2-stage Acceleration
and 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:
C_01, C_02, C_03, C_04,
C_05
Required settings: A_92, A_93, A_94=00
Notes:
•
Function A_94 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.
