  • Page 30: Notes On The Application

    Comparisons with commercial power operation The VF-AS1 Inverter employs the sinusoidal PWM system to supply the motor. This is why compared to operation with a commercial power there will be a slight increase in motor temperature, noise and vibration. The main supply voltage and current will also be distorted due to harmonic distortion while increase the line current.
  • Page 31 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 32 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 33: 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 34 E6581301 Remedies: Use the electronic thermal overload built into the inverter. The setting of the electronic thermal overload is done using parameter 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 This can be improved by installing 0.1µ~0.5µF-1000V film capacitor to the input/output terminals of each phase in the thermal overload relay.
  • Page 35: Measuring Position

    E6581301 1.4.4 Installation Installation environment The VF-AS1 Inverter is an electronic control instrument. Take full consideration to installing it in the proper operating environment. • @ • @ Danger • E Do not place any inflammable substances near the VF-AS1 Inverter.
  • Page 36: How To Install

    Please consult with your supplier about these measures. • E If the VF-AS1 Inverter is installed near any of the equipment listed below, provide measures to insure against errors in operation. Solenoids: Attach surge suppressor on coil. Brakes: Attach surge suppressor on coil.
  • Page 37 E6581301 Install the inverter in a well-ventilated indoor place and mount it on a flat metal plate in portrait orientation. If you are installing more than one inverter, the separation between inverters should be at least 5cm, and they should be arranged in horizontal rows.

  • Page 39: Calorific Values Of The Inverter And The Required Ventilation

    E6581301 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 about 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.
  • Page 40: Panel Designing Taking Into Consideration The Effects Of Noise

    E6581301 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. • E 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 41: Connection Equipment

    E6581301 2. Connection equipment • @ • @ Danger • E Never disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call your sales agency. Disassembly prohibited • E 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 42 Control and main power supply The control power supply and the main circuit power supply for the VF-AS1 are the same. If a malfunction or trip causes the main circuit to be shut off, control power will also be shut off.
  • Page 43: Standard Connections

    E6581301 Standard connections • @ • @ Danger • E 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. • E Do not connect a regenerative braking resistor to any DC terminal (between PA/+ and PC/-, or between PO and PC/-).
