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 accelera-
tion/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 decelera-
tion 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).

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:
C001, C002, C003, C004, 
C005
Required settings:
A092, A093, A094=00
Notes:
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.
