function: U02 to U05 when the set value "2" is selected.

The detail is referred to the function: U02 to U05. [S-shape acceleration and deceleration]

This pattern reduces shock by mitigating output frequency changes at the beginning/end of acceleration and deceleration.

When acceleration and deceleration times are very long or short, acceleration and deceleration are rendered linear.

It may be switched the acceleration and deceleration time during constant speed or stopping by the function "acceleration and deceleration time selection"(E01 to E09: 4, 5).

The signal may be ignored switched during S-shape at acceleration.

The linear deceleration time is corresponded if switched during S-shape at deceleration.

It may be switched to the S-shape operation if output frequency is reached to the setting frequency or change to acceleration control.

[ Curvilinear acceleration and deceleration ]

This function is used to minimize motor acceleration and deceleration times in the range that includes a constant-output range.

a connection between the REV and P24 terminals, inadvertent activation of the REV key, or negative analog input from terminal 12 or V1. During this function is operating, "0.00Hz" is displayed on the LED monitor.

This function cannot be prevented against H18: Torque control function. It may be reverse because of the torque signal and load.
