Page 184: Inverter-Driven 400V Class Motor
.4 Inverter-driven 400V class motor In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures: # Measures It is recommended to take either of the following measures:…

173 (8) Cable thickness and w iring distance If the inverter-to-motor wiring distance is long, the motor torque will decrease due to a voltage drop in the main circuit cables especially a t low frequency output. Use thick cables for wiring to make a voltage drop less than 2%. (A selection example for the wiring distance of 20m (65.62feet) is given …

175 5 .4 Inverter-driv en 400V clas s motor In the PW M type inv erter, a s urge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter, consider the following measures: # Measures It is rec …
