Setting parameters
a) Operating method: Terminal input
Set the command mode selection EOQF 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

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.
