Two Stage Acceleration and Deceleration

When terminal [2CH] is turned ON, the
inverter changes the rate of acceleration and
deceleration from the initial settings
and
F003)
acceleration/ deceleration values. When the
terminal is turned OFF, the inverter is
returned to the original acceleration and
deceleration time
and
F003
(acceleration time 2) and
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).
