2.5.3
Select a recommended size cable to ensure that the voltage drop ratio is within 2%.
If the wiring distance is long between the inverter and motor, the voltage drop in the main circuit will cause the motor torque to
decrease especially at a low speed.
The following tables show the recommended cable gauges for 20 m power cables.
 For LD rating (Pr.570 Multiple rating setting = "1")
• 200 V class (220 V input power supply, without a power factor improving AC or DC reactor)
