Two Stage Acceleration and Deceleration
When terminal [2CH] is turned ON, the inverter
changes the
deceleration from the initial settings
) 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
deceleration time 1). Use

time 2) and
the second
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 ().
