Two Stage Acceleration and Deceleration
When terminal [2CH] is turned ON, the inverter
changes the
deceleration from the initial settings
F003) to use the second set of acceleration/
deceleration values. When the terminal is
turned OFF, the inverter is returned to the
original acceleration and deceleration time
(F002 acceleration
deceleration time 1). Use
A093
time 2) and
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).
