F2 & F3: Accel/Decel Pattern
Range: 0 (Linear), 1 (S-curve), (Default 0)
Description: This parameter determines the shape of the accel/decel ramp. Different
combinations of acceleration and deceleration patterns can be selected
according to the applications.
Display:
Function:
Linear The shape of the ramp is a straight line and is a general
pattern for constant torque applications.
S-curve This pattern allows the motor to accelerate and decelerate
smoothly. The actual acceleration and deceleration time
takes longer - about 40% than time set by user. This
setting prevents shock during acceleration and
deceleration, and prevents objects from swinging on
conveyors or other moving equipment.
z Note: Depending on the setting of this parameter the exact values in
DRV-01 (Accel Time) and DRV-02 (Decel Time) may not represent the
actual accel or decel times.
