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.
