  • Page 2 E6581301 I. Safety precautions The items described in these instructions and on the inverter itself are very important so that you can use the inverter safely prevent injury to yourself and other people around you as well as prevent damage to property in the area. Thoroughly familiarize yourself with the symbols and indications shown below and then continue to read the manual.
  • Page 3 E6581301 General Operation   Danger Reference ・Never disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call your sales agency. Disassembly prohibited ・Never remove the front cover when power is on or open door if enclosed in a cabinet. The unit contains many high voltage parts and contact with them will result in electric shock.
  • Page 4 Operation cannot be stopped immediately by the inverter alone, thus risking an accident or injury. ・All options used must be those specified by Toshiba. 1.4.4 The use of any other option may result in an accident.
  • Page 5 E6581301 Wiring   Danger Reference ・Do not connect input power to the output (motor side) terminals (U/T1,V/T2,W/T3). That will destroy the inverter and may result in fire. ・Do not connect resistors to the DC terminals (across PA-PC or PO-PC). That may cause a fire. Prohibited Connect resistors as directed by the instructions for “Installing separate braking resistors.”...
  • Page 6 E6581301 Operations   Danger Reference ・Do not touch inverter terminals when electrical power is applied to the inverter even if the motor is stopped. Touching the inverter terminals while power is connected to it may result in electric shock. ・Do not touch switches when thands are wet and do not try to clean the inverter with a damp cloth.
  • Page 7 E6581301 Maintenance and inspection   Danger Reference 14.2 ・Never replace any part by yourself. This could be a cause of electric shock, fire and bodily injury. To replace parts, call the local sales agency. Prohibited ・The equipment must be inspected every day. If the equipment is not inspected and maintained, errors and malfunctions may not be discovered which could lead to accidents.

    E6581301 Notes on the application 1.4.1 Motors Keep the following in mind when using the VF-AS1 to drive a motor.   Warning 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 26 E6581301 Braking a motor when power supply is lost A motor with its power cut off goes into freewheel, and does not stop immediately. To stop the motor quickly as soon as the power is cut off install an auxiliary brake. There are different kinds of brake devices, both electrical and mechanical.
  • Page 27: Inverters

    E6581301 1.4.2 Inverters Protecting inverters from overcurrent The inverter has an overcurrent protection function. The programmed current level is set to the inverter's maximum applicable motor. If the motor used has a small capacity, the stall prevention level, overcurrent level and the motor electronic thermal protection must be readjusted.
  • Page 28: What To Do About The Leak Current

    E6581301 1.4.3 What to do about the leak current   Warning Current may leak through the inverter's input/output wires because of insufficient electrostatic capacity on the motor with bad effects on peripheral equipment. The leakage current's value is affected by the carrier frequency and the length of the input/output wires.
  • Page 29 E6581301 Remedies: Use the electronic thermal overload built into the inverter. The setting of the electronic thermal overload is done using parameter  or  . Reduce the inverter's PWM carrier frequency. However, that will increase the motor's acoustic noise. The setting of PWM carrier frequency is done with the parameter ...

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 35: Connection Equipment

    E6581301 2. Connection equipment   Danger ・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 36 E6581301   Warning ・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).
  • Page 37: Standard Connections

    E6581301 Standard connections   Danger ・Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3). Connecting input power to the output could destroy the inverter or cause a fire. ・Do not connect a regenerative braking resistor to any DC terminal (between PA and PC or between PO and PC).
