■Setting parameters

a)Operating method: Terminal input

Set the command mode selection ￿￿￿￿ to ￿.

b)Use the S2 and S3 terminals for switching. (Instead, other terminals may be used.)

S2: Acceleration/deceleration switching signal 1

S3: Acceleration/deceleration switching signal 2

Title	Function	Adjustment range	Example of setting
￿￿￿￿	Input terminal function selection 6 (S2)	￿~￿￿￿	￿￿ (Acceleration/deceleration
			switching signal 1)
￿￿￿￿	Input terminal function selection 7 (S3)	￿~￿￿￿	￿￿ (Acceleration/deceleration
			switching signal 2)

■Acceleration/deceleration pattern

Acceleration/deceleration patterns can be selected individually, using the acceleration/deceleration 1, 2, 3 and 4 parameters.

1)Straight acceleration/deceleration

2)S-pattern acceleration/deceleration 1

3)S-pattern acceleration/deceleration 2

	1) Straight acceleration/deceleration
	A general acceleration/deceleration pattern.
	This pattern can usually be used.

2) S-pattern acceleration/deceleration 1

￿￿￿

Select this pattern to accelerate/decelerate the motor rapidly to a high-speed region with an output frequency of 60Hz or more or to minimize the shocks applied during acceleration/deceleration. This pattern is suitable for conveyer machines.

★Both the S-pattern lower-limit setting (￿￿￿￿, ￿￿￿￿) and the S-pattern upper limit setting (￿￿￿￿,

￿￿￿￿) affect all acceleration/deceleration pattern settings.
