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).
