    E6581528 Notes on the application 1.5.1 Motors Keep the following in mind when using the VF-AS1 to drive a motor. Caution Use an inverter that conforms to the specifications of power supply and three-phase induction motor being used. If the inverter being used does not conform to those specifications, not only will the three-phase induction motor not rotate correctly, but it may cause serious accidents through Mandatory overheating and fire.

  • Page 37: What To Do About The Leak Current

    E6581528 If power supply distortion is not negligible If the power supply distortion is not negligible because the inverter shares a power distribution line with other systems causing distorted waveforms, such as systems with thyristers or large-capacity inverters, install an input reactor to improve the input power factor, to reduce higher harmonics, or to suppress external surges.

    E6581528 (2) Affects of leakage current across supply lines Thermal relay inverter Power supply Leakage current path across wires ○ Thermal relays The high frequency component of current leaking into electrostatic capacity between inverter output wires will increase the effective current values and make externally connected thermal relays operate improperly. If the motor cables are more than 50m long, external thermal relay may operate improperly with models having motors of low rated current because the leakage current will be high in proportion to the motor rating.

    E6581528 Calorific values of the inverter and the required ventilation The energy loss when the inverter converts power from AC to DC and then back to AC is typically about 2.5% to 5%. In order to suppress the rise in temperature inside the cabinet when this loss becomes heat loss, the interior of the cabinet must be ventilated and cooled.

    E6581528 Panel designing taking into consideration the effects of noise The inverter generates high frequency noise. When designing the control panel setup, consideration must be given to that noise. Examples of measures are given below. • Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the same conduit, do not run them parallel, and do not bundle them.

  • Page 46: Cautions On Wiring

    E6581528 2. Connection equipment Warning • Never disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call your sales agency. Disassembly prohibited • Don't stick your fingers into openings such as cable wiring hole and cooling fan covers. This can result in electric shock or other injury.

  • Page 47

    E6581528 Caution • Do not attach devices with built-in capacitors (such as noise filters or surge absorber) to the output (motor side) terminal. This could cause a fire. Prohibited Preventing radio noise To prevent electrical interference such as radio noise, separately bundle wires to the main circuit's power terminals (R/L1, S/L2, T/L3) and wires to the motor terminals (U/T1, V/T2, W/T3).
