5.2 Group 1: Basic Parameters

01 - 00

Maximum Output Frequency

Settings
This parameter determines the AC drives maximum output frequency. All master frequency
commands set by the keypad or analog inputs are limited by this parameter. The analog
commands (AVI, ACI1 and ACI2) may be scaled to correspond to the output frequency
range. (Please refer to 04-09~04-20.)
01 - 01

Maximum Voltage Frequency (Base Frequency)

Settings
This parameter sets the frequency, where the maximum output voltage (Pr. 01-02) will be
reached. The output frequency may exceed this setting, but the output voltage doesn't
increase beyond this point. This parameter should be set according to the rated frequency
of the motor as indicated on the motor nameplate.
If this parameter setting is smaller than the rated frequency of the motor, nuisance over
current faults or damage to the AC drive may occur.
If this parameter setting is greater than the rated frequency of the motor, the motor will
encounter torque loss.
01 - 02

Maximum Output Voltage

Settings
This parameter determines the Maximum Output Voltage of the AC drive. This parameter
setting should be set according to rated voltage of the motor as indicated on the motor
nameplate. If rated voltage of the motor is 440V, this parameter must be set to 440V. If rated
voltage of the motor is 380V, this parameter must be set to 380V.
If this setting is greater than the rated voltage of the motor, nuisance over current faults or
damage to the AC drive may occur.
01 - 03 Mid-point Frequency
Settings
This parameter sets the Mid-point Frequency of the V/f curve.
This parameter must meet the following argument. Pr.1-01 >= Pr.1-03 >= Pr.1-05.
