6.5 Set V/F pattern
6.5.1 Base frequency, voltage (Pr. 3, Pr. 19, Pr. 47)
Used to adjust the inverter outputs (voltage, frequency) to the motor rating.
햲
The above parameter can be set when Pr. 160 "User group read selection" = 0.
Setting of base frequency (Pr. 3)
When operating a standard motor, generally set the rated frequency of the motor to Pr. 3 "Base
frequency".
When running the motor using commercial power supply-inverter switch-over operation, set Pr. 3 to
the same value as the power supply frequency.
If the frequency given on the motor rating plate is "60 Hz" only, always set to "60 Hz". It may result in
an inverter trip due to overload. Caution must be taken especially when Pr. 14 "Load pattern selection"
= "1" (variable torque load)
