11: 60 Hz, medium starting torque
12: 60 Hz, high starting torque
13: 90 Hz, voltage saturation in 60 Hz
14: 120 Hz, voltage saturation in 60 Hz
15: 180 Hz, voltage saturation in 60 Hz
 When setting to 0, refer to Pr.01-01–01-08 for the motor 1 V/F curve. For motor 2, refer to
Pr.01-35–01-42.
 When setting to 1 or 2, the second and third voltage frequency settings are invalid.
 If the load of the motor is a variable torque load (torque is in direct proportion to the rotating speed,
such as the load of a fan or a pump), the load torque is low at low rotating speed. You can decrease
the input voltage appropriately to make the magnetic field of the input current smaller and reduce
flux loss and iron loss for the motor to increase efficiency.
 When you set the V/F curve to high power, it has lower torque at low frequency, and the drive is
not suitable for rapid acceleration and deceleration. Do NOT use this parameter for rapid
acceleration and deceleration.

Auto-Acceleration and Auto-Deceleration Setting
Default: 0
Settings 0: Linear acceleration and deceleration
1: Auto-acceleration and linear deceleration
2: Linear acceleration and auto-deceleration
3: Auto-acceleration and auto-deceleration
4: Linear, stall prevention by auto-acceleration and auto-deceleration
(limited by Pr.01-12–Pr.01-21)
 0 (linear acceleration and linear deceleration): the drive accelerates and decelerates according to
the setting for Pr.01-12–01-19.
 1 or 2 (auto / linear acceleration and auto / linear deceleration): the drive auto-tunes the
acceleration and deceleration to effectively reduce the mechanical vibration during the load start-
up and stop and make the auto-tuning process easier. It does not stall during acceleration and
does not need a brake resistor during deceleration to stop. It can also improve operation efficiency
and save energy.
 3 (auto-acceleration and auto-deceleration–decelerating by the actual load): the drive auto-detects
the load torque and automatically accelerates from the fastest acceleration time and smoothest
start-up current to the setting frequency. During deceleration, the drive automatically determines
