  • Page 28: Grounding Capacitor Switching Method

    E6581445 1.3.3 Grounding capacitor switching method The inverter is grounded through a capacitor. The leakage current from the inverter can be reduced using the selector switch, switching bar or switching screw (depending on the model) on the main circuit terminal board. This switching device is used to detach the capacitor from the grounding circuit or to reduce its capacitance.

  • Page 32: 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 33

    E6581445 High-speed operation at and above 60Hz (rated frequency) Operating at frequencies greater than 60Hz will increase noise and vibration. There is also a possibility that such operation will exceed the motor's mechanical strength under these conditions and the bearing limits. You should verify with the motor's manufacturer operating.

  • Page 34

    E6581445 In circuit configuration 1, the brake is turned on and off through MC2 and MC3. If the circuit is configured in some other way, the overcurrent trip may be activated because of the locked rotor current when the brake goes into operation.

  • Page 35: What To Do About The Leak Current

    E6581445 There is no fuse in the inverter's main circuit. Thus, as the diagram above shows, when more than one inverter is used on the same power line, you must select interrupting characteristics so that only the MCCB2 will trip and the MCCB1 will not trip when a short occurs in the inverter (INV1).

  • Page 36

    E6581445 (2) Affects of leakage current across supply lines Thermal relay inverter Power supply Leakage current path across wires (1) 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, especially the 400V class low capacity (3.7kW or less) models, because the leakage current will be high in proportion to the motor rating.

  • Page 37: Installation Environment

    E6581445 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 • Do not place any inflammable substances near the VF-AS1 Inverter. If an accident occurs in which flames are emitted, this could lead to fire.

  • Page 38

    Please consult with your supplier about these measures. • 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 39

    E6581445 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.

    E6581445 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 42

    E6581445 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 43: Cautions On Wiring, Connection Equipment

    E6581445 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.

    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 45: Standard Connections

    E6581445 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/-).

    Inverters themselves are not subject to approval for CE marking. The CE mark must be put on every final product that includes an inverter(s) and a motor(s). The VF-AS1 series of inverters complies with the EMC directive if an EMC filter recommended by Toshiba is connected to it and wiring is carried out correctly.

Models with a built-in EMC filter (1) 200V class: VFAS1-2004PL~2075PL 400V class: VFAS1-4007PL~4500KPC The above mentioned models install EMC noise filter inside. So the conducted and radiated noise can be reduced, optional EMC noise filters are not needed.

    E6581445 Replacement of expendable parts The inverter is composed of a large number of electronic parts including semiconductor devices. The following parts deteriorate with the passage of time because of their composition or physical properties. The use of aged or deteriorated parts leads to degradation in the performance or a breakdown of the inverter.

  • Page 316: Making A Call For Servicing, Keeping The Inverter In Storage

    14.3 Making a call for servicing For the Toshiba service network, refer to the back cover of this instruction manual. If defective conditions are encountered, please contact the Toshiba service section in charge via your Toshiba dealer. When making a call for servicing, please inform us of the contents of the rating label on the right panel of the inverter, the presence or absence of optional devices, etc., in addition to the details of the failure.
