Two Stage Acceleration and Deceleration

When terminal [2CH] is turned ON, the inverter changes the rate of acceleration and deceleration from the initial settings (F002 and F003) 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 (F002 acceleration time 1, and F003 deceleration time 1). Use A092 (acceleration time 2) and A0093 (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 (F002) to acceleration 2 (A092).

Option	Terminal	Function Name	State	Description
Code	Symbol
09	2CH	Two-stage Accelera-	ON	Frequency output uses 2nd-stage acceleration and
		tion and Deceleration		deceleration values
			OFF	Frequency output uses the initial acceleration 1
				and deceleration 1 values

Valid for inputs:	C001~C005
Required settings	A092, A093, A094=00
Notes:

•Function A094 selects the method for second stage acceleration. It must be set = 00 to select the input terminal method in order for the [2CH] terminal assignment to operate.
