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
) 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
(
acceleration
time
1,
and
deceleration time 1). Use
(acceleration
time 2) and
(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 (
) to acceleration 2 (
).
