Page 5 E6581528 Wiring Warning 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 (between PA/+ and PC/-, or between PO and PC/-).
Page 6 E6581528 Operations Warning 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: Maintenance And Inspection
E6581528 Maintenance and inspection Warning Reference • Never replace any part by yourself. 14.2 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 frequently. If the equipment is not inspected and maintained, errors and malfunctions may not be discovered which could lead to accidents.

Page 34: Notes On The Application
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.

E6581528 Loads that generate negative torque When combined with loads that generate negative torque the protection for overvoltage and overcurrent on the inverter will go into operation and may cause a trip. For this kind of situation, you must install a dynamic braking resistor, etc.

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.
Page 38 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.
Page 39: Installation
E6581528 1.5.4 Installation Installation environment The VF-AS1 Inverter is an electronic control instrument. Take full consideration to installing it in the proper operating environment. Warning • 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. Prohibited •...
Page 40 Operation cannot be stopped immediately by the inverter alone, thus risking an accident or injury. • All options used must be those specified by Toshiba. The use of any other option may result in an accident.
Page 41 E6581528 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 43 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.
Page 44 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: Connection Equipment
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).
Page 48: Standard Connections
E6581528 • Refer to the table in Section 10.1 for wire sizes. • The length of the main circuit wire in Section 10.1 should be no longer than 30m. If the wire is longer than 30m, the wire size (diameter) must be increased. •...

The operation frequency restarts to increase when torque decreases as a result of the release of the mechanical brake, so the time required for the specified speed to be reached is the sum of the delay in operation of the mechanical brake and the acceleration time.

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.
Page 233: Measures To Satisfy The Emc Directive
E6581528 9.1.2 Measures to satisfy the EMC directive Concrete measures for EMC directive of CE markings are shown below. Models with a built-in EMC filter (1) 690V class: VFAS1-6022PL to 6630KPC 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.
Page 234: Low-Voltage Directive
Fig. 1 9.1.3 Low-voltage directive The low-voltage directive provides for the safety of machines and systems. All Toshiba inverters are CE-marked in accordance with the standard IEC61800-5-1 specified by the low-voltage directive, and can therefore be installed in machines or systems and imported without a problem to European countries.

(1) Shut off all input power to the inverter.
Page 323: Periodical Inspection
E6581528 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 (1400VDC or more), and check that the voltage to the DC main circuits (between PA/+ and PC/-) does not exceed 45V.
Page 324 E6581528 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 325: 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 326: 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 328: Disposal Of The Inverter
E6581528 16. Disposal of the inverter Warning • 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.
