If this parameter setting is less than the rated frequency of the motor, it may cause over
current and damage the motor or trigger the over current protection.
If this parameter setting is greater than the rated frequency of the motor, it may cause
insufficient motor torque.
Related parameters: Pr.01.02(Maximum Output Voltage (Vmax) (Motor 0)), Pr.01.03(Mid-Point
Frequency (Fmid) (Motor 0)), Pr.01.04(Mid-Point Voltage (Vmid) (Motor 0)), Pr.01.05(Minimum
Output Frequency (Fmin) (Motor 0)) and Pr.01.06(Minimum Output Voltage (Vmin) (Motor 0)).
01.02 Maximum Output Voltage (Vmax) (Motor 0) Unit: 0.1
Settings 115V/230V series 0.1 to 255.0V Factory Setting: 220.0
460V series 0.1 to 510.0V Factory Setting: 440.0
This parameter determines the Maximum Output Voltage of the AC motor drive. The Maximum
Output Voltage setting must be smaller than or equal to the rated voltage of the motor as
indicated on the motor nameplate. This parameter value must be equal to or greater than the
Mid-Point Voltage (Pr.01.04).
If the output voltage of the AC motor drive is smaller than this setting, the output voltage can’t
reach this setting due to input voltage limit.
If this setting is greater than the rated voltage of the motor, it may cause over current of the
motor output to damage motor or trigger the over current protection.
If this setting is smaller than the rated voltage of the motor, it may cause the insufficient motor
torque.
Related parameters: Pr.01.01(Maximum Voltage Frequency (Fbase) (Motor 0)), Pr.01.03(Mid-
Point Frequency (Fmid) (Motor 0)), Pr.01.04(Mid-Point Voltage (Vmid) (Motor 0)),
Pr.01.05(Minimum Output Frequency (Fmin) (Motor 0)) and Pr.01.06(Minimum Output Voltage
(Vmin) (Motor 0)).
01.03 Mid-Point Frequency (Fmid) (Motor 0) Unit: 0.01
Settings 0.10 to 600.0Hz Factory Setting: 1.50
This parameter sets the Mid-Point Frequency of the V/f curve. With this setting, the V/f ratio
between Minimum Frequency and Mid-Point frequency can be determined. This parameter
must be equal to or greater than Minimum Output Frequency (Pr.01.05) and equal to or less
than Maximum Voltage Frequency (Pr.01.01).
