
Accel/Decel pattern is settable at F2 and F3.
 Linear: This is a general pattern for constant torque applications.
 S-curve: This curve allows the motor to accelerate and decelerate smoothly.
CAUTION:
For S-curve, the actual Accel/Decel time takes longer than the time set by user.
 H17 sets the starting ratio between S-curve and Linear in 1/2 of Accel/Decel Ref. Frequency. For
smooth Accel/Decel starting, increase H17 to extend S-curve ratio.
 H18 sets the ending ratio between S-curve and Linear in 1/2 of Accel/Decel Ref. Frequency. For
smooth and accurate speed arrival and stopping, increase H18 to extend S-curve ratio.
