3: 60Hz, voltage is saturated when it’s 50Hz
4: 72Hz, voltage is saturated when it’s 60Hz
5: 50Hz, decrease gradually with third power
6: 50Hz, decrease gradually with square
7: 60Hz, decrease gradually with third power
8: 60Hz, decrease gradually with square
9: 50Hz, medium starting torque
10: 50Hz, large staring torque
11: 60Hz, medium starting torque
12: 60Hz, large starting torque
13: 90Hz, voltage is saturated when it’s 60Hz
14: 120Hz, voltage is saturated when it’s 60Hz
15: 180Hz, voltage is saturated when it’s 60Hz
When setting to 0, refer to Pr.01-01~01-08 for motor 1 V/f curve. For motor 2, please refer to
Pr.01-35~01-42.
When setting to 1 or 2, 2
nd
and 3
rd
voltage frequency setting are invalid.
If motor load is variable torque load (torque is in direct proportion to speed, such as the load of fan
or pump), it can decrease input voltage to reduce flux loss and iron loss of the motor at low speed
with low load torque to raise the entire efficiency.
When setting higher power V/f curve, it is lower torque at low frequency and is not suitable for rapid
acceleration/deceleration. It is recommended Not to use this parameter for the rapid
acceleration/deceleration.

Optimal Acceleration/Deceleration Setting
Factory Setting: 0
Settings 0: Linear accel./decel.
1: Auto accel., linear decel.
2: Linear accel., auto decel.
3: Auto accel./decel. (auto calculate the accel./decel. time by actual load)
4: Stall prevention by auto accel./decel. (limited by 01-12 to 01-21)
Pr.01-44 is used to reduce the drive’s vibration during load starts and stops. Also it will speed up to
the setting frequency with the fastest and smoothest start-up current when it detects small torque.
