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.
Appropriate applications: Elevator door, lifts
Caution :
For S-curve, the actual Accel/Decel time takes longer than the time set by user.
