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.
The figures at left show the acceleration
characteristics. Similar characteristics apply to the
deceleration.
• Choosing S-curve acceleration/deceleration or curvilinear acceleration/deceleration in Acceleration/
Deceleration Pattern (H07), extends acceleration/deceleration times are longer than specified times.
• Specifying an improperly short acceleration/deceleration time may activate the current limiter, torque
limiter, or anti-regenerative control, resulting in a longer observed acceleration/deceleration time.
