01 Basic Parameters
You can set this parameter during operation.
Motor 1 Maximum Operation Frequency
Motor 2 Maximum Operation Frequency
Motor 3 Maximum Operation Frequency
Motor 4 Maximum Operation Frequency
Determines the AC motor drive’s maximum operation frequency. All the AC motor drive
frequency command sources (analog inputs 0–10 V, 4–20 mA, 0–20 mA, ±10 V) are scaled to
correspond to the output frequency range.
Motor 1 Rated / Base Frequency
Motor 2 Rated / Base Frequency
Motor 3 Rated / Base Frequency
Motor 4 Rated / Base Frequency
Set this parameter according to the motor’s rated frequency on the motor nameplate. If the
motor’s rated frequency is 60 Hz, set this parameter to 60. If the motor’s rated frequency is 50
Hz, set this parameter to 50.
Motor 1 Rated / Base Voltage
Motor 2 Rated / Base Voltage
Motor 3 Rated / Base Voltage
Motor 4 Rated / Base Voltage
Default: 220.0 / 440.0 / 575.0
115V / 230V models: 0.0–255.0 V
Set this parameter according to the rated voltage on the motor nameplate. If the motor’s rated
voltage is 220 V, set this parameter to 220.0. If the motor’s rated voltage is 200 V, set this
parameter to 200.0.
There are many motor types in the market and the power system for each country is also
different. The economical and convenient solution is to install an AC motor drive. Then there is
no problem using the motor with different voltage and frequency inputs, and the motor drive can
improve the original motor characteristics and useful life.
