put sides, and also install the Inverter in a totally enclosed steel box. The cable between the Inverter and the motor should be as short as possible. Steel box Power supply <strong>3G3HV</strong> Metal pipe Noise filter Noise filter Cable Length between Inverter and Motor If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust the carrier frequency (set in n050) as shown in the table below. Cable length 50 m max. 100 m max. More than 100 m Carrier frequency 15 kHz max (6 max.) 10 kHz max. (4 max.) 5 kHz max. (2 max.) (n050) Note The carrier frequency setting range varies depending on the Inverter capacity. 200-V class, 18.5 kW max.; 400-V class, 30 kW max.: 0.4 to 15.0 kHz 200-V class, 30 to 75 kW; 400-V class, 30 to 160 kW: 0.4 to 10.0 kHz 400-V class, 185 to 300 kW: 0.4 to 2.5 kHz Ground Wiring • Always use the ground terminal of the 200-V Inverter with a ground resistance of less than 100 Ω and that of the 400-V Inverter with a ground resistance of less than 10 Ω. • Do not share the ground wire with other devices such as welding machines or power tools. • Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the ground wire. Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
• When using more than one Inverter, be careful not to loop the ground wire. Countermeasures against Harmonics With the continuing development of electronics, the generation of harmonics from industrial machines has been causing problems recently. Refer to the following for the definition of harmonics (i.e., harmonic currents with voltages) and countermeasures against the generation of harmonics from the Inverter. Harmonics (Harmonic Currents with Voltages) • Definition Harmonics consist of electric power produced from AC power and alternating at frequencies that are integral multiples of the frequency of the AC power. The following are the harmonic frequencies of a 60- or 50-Hz commercial power supply.
