 The first basic parameter “” (history function) is displayed.

Turn the setting dial to change the parameter to .

Parameter values can be read by pressing the center of the setting
dial (default setting is 100%).

Turn the setting dial to change the parameter to % (= motor
rated current/inverter output rated current

⇔
Press the center of the setting dial to save the changed parameter.
 and the parameter are displayed alternately.
Note: The rated output current of the inverter should be calculated from the rated current for frequencies
below 4kHz, regardless of the setting of the PWM carrier frequency parameter ().

VF motors (motors designed for use with inverters) can be used in frequency ranges lower than those
for standard motors, but their cooling efficiency decreases at frequencies below 6Hz.
