L100 Inverter

Two-stage Acceleration and Deceleration

When terminal [2CH] is turned ON, the inverter changes the rate of acceleration and deceleration from the initial settings (F_02 and F_03) to use the second set of accelera- tion/deceleration values. When the terminal is turned OFF, the inverter is returned to the original acceleration and deceleration time (F_02 acceleration time 1, and F_03 deceleration time 1). Use A_92 (acceleration time 2) and A_93 (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 (F_02) to acceleration 2 (A_92).
