Two-stage Acceleration and Deceleration
When terminal [2CH] is turned on, the
inverter changes the rate of acceleration and
deceleration from the initial settings (F02 and
F03) to use the second set of acceleration/
deceleration values. When the terminal is
turned off, the equipment is returned to the
original acceleration and deceleration time
(F02 acceleration time 1, and F03 decelera-
tion time 1). Use A92 (acceleration time 2)
and A93 (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 (F02) to acceleration 2 (A92).

Description
09 2CH Two-stage Accelera-
tion 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:
C01, C02, C03, C04, C05, C06
Required settings:
A92, A93, A94=0
Notes:
•
Function A94 selects the method for second stage
acceleration. It must be 00 to select the input
terminal method in order for the 2CH terminal
assignment to operate.
