Group 1: Basic Parameters

01 - 00 Maximum Output Frequency

Settings 50.00~160.00HzFactory Setting: 60.00 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 (ACI1 and ACI2) may be scaled to correspond to the output frequency range. (Please refer to 04-05~04-12.)

01 - 01 Maximum Voltage Frequency (Base Frequency)

Settings 0.10~160.00 HzFactory Setting: 60.00 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 0.2V ~ 510.0VFactory Setting: 440.0 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	0.10~160.00 Hz	Factory Setting: 3.00

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.
