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
)
acceleration/ deceleration values. When the
terminal is turned OFF, the inverter is
returned to the original acceleration and
deceleration time
and

(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 () to acceleration 2
().
