Curvilinear acceleration/deceleration

Acceleration/deceleration is linear below the base frequency (constant torque) but it slows down

above the base frequency to maintain a certain level of load factor (constant output).

This acceleration/deceleration pattern allows the motor to accelerate or decelerate with its

maximum performance.

• If you choose S-curve acceleration/deceleration or curvilinear acceleration/

deceleration

acceleration/deceleration times are longer than the specified ones.

• Specifying an improperly short acceleration/deceleration time may activate the

current limiter, torque limiter, or anti-regenerative control (automatic

deceleration), resulting in a longer acceleration/deceleration time than the

specified one.
