ing

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).

A_92, A_93, A_94=00

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.
