Group 1: Basic Parameters

01 - 00

Maximum Output Frequency (Fmax) Factory Setting: 60.00

Settings 50.00 to 400.00 Hz Unit: 0.01Hz

 This parameter determines the AC drive’s Maximum Output Frequency. All the AC drive

analog inputs (0 to +10V, 4 to 20mA, -10V to +10V) are scaled to correspond to the output

frequency range.

01 - 01

Maximum Voltage Frequency (Fbase) Factory Setting: 60.00

Settings 0.10 to 400.00Hz Unit: 0.01Hz

 This value should be set according to rated frequency of the motor as indicated on the

motor nameplate. Maximum Voltage Frequency determines the volts per hertz ratio. For

example, if the drive is rated for 460 VAC output and the Maximum Voltage Frequency is

set to 60Hz, the drive will maintain a constant ratio of 7.66 V/Hz (460V/60Hz=7.66V/Hz).

This parameter value must be equal to or greater than the Mid-Point Frequency

(Pr.01-03).

01 - 02

Maximum Output Voltage (Vmax) Unit: 0.1

Settings 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 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).

01 - 03

Mid-Point Frequency (Fmid) Factory Setting: 0.50

Settings 0.10 to 400.00Hz Unit: 0.01Hz

 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).

01 - 04

Mid-Point Voltage (Vmid) Unit: 0.1

Settings 230V series 0.1 to 255.0V Factory setting: 1. 7V

460V series 0.1 to 510.0V Factory setting: 3.4V
