  • Page 31 E6581442 High-speed operation at and above 50Hz/60Hz (rated frequency) Operating at frequencies greater than 50Hz/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.

    Circuit configuration 2 uses low-speed signal OUT1 to turn on and off the brake. Turning the brake on and off with a low-speed detection (OUT1 function) may be better in such applications as elevators. Please confer with your Toshiba distributor before designing the system. Measures to protect motors against surge voltages In a system in which a 400V-class inverter is used to control the operation of a motor, very high surge voltages may be produced.
  • Page 33: What To Do About The Leak Current

    If the sensors and CRT are affected, it can be remedied by reducing the PWM carrier frequency described in 1 above, but if this cannot be remedied because of the increase in the motor's electric magnetic noise, please consult with your Toshiba distributor. * Cautions for applying models with a built-in noise filter.
  • Page 34 E6581442 (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 (3.7/4.0kW or less) models, because the leakage current will be high in proportion to the motor rating.

  • Page 42 E6581442  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.

So the conducted and radiated noise can be reduced, optional EMC noise filters are not needed.
  • Page 234 E6581442 (2) Use shielded power cables and control signal cables for the input and output lines of the inverter. Route the cables and wires so as to minimize their lengths. Keep a distance between the power cable and the control cable and between the input and output wires of the power cable.

    E6581442 Compliance with safety standards The VFAS1 inverter has the “power removal” safety function that complies with safety standards. To ensure safety performance, however, the mechanical system with which the VFAS1 inverter is used has to adhere to such standards as a whole. To be more specific, in order for the system to satisfy the following safety standards, it needs to be configured, as shown on the next page, with the power removal terminal of the VFAS1 inverter (PWR terminal on the control terminal board) so that it will coast or decelerate to a stop in the event of a failure.

If the equipment is not inspected and maintained, errors and malfunctions may not be discovered which could lead to accidents. Mandatory • Before inspection, perform the following steps. (1) Shut off all input power to the inverter.
  • Page 330: Periodical Inspection

    E6581442 14.2 Periodical inspection Make a periodical inspection at intervals of 3 or 6 months depending on the operating conditions. Warning • Before inspection, perform the following steps. (1) Shut off all input power to the inverter. (2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit. Mandatory (3) Use a tester that can measure DC voltages (800VDC or more), and check that the voltage to the DC main circuits (between PA/+ and PC/-) does not exceed 45V.

  • Page 332: Making A Call For Servicing

    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.
  • Page 333: Warranty

    • Failure or damage caused by the use of the inverter for any purpose or application other than the intended one 4. All expenses incurred by Toshiba for on-site services shall be charged to the customer, unless a service contract is signed beforehand between the customer and Toshiba, in which case the service contract has priority over this warranty.
  • Page 334: Disposal Of The Inverter

    E6581442 16. Disposal of the inverter Caution • For safety's sake, do not dispose of the disused inverter yourself but ask an industrial waste disposal agent (*). If the collection, transport and disposal of industrial waste is done by someone who is not Mandatory licensed for that job, it is a punishable violation of the law.
