Caution Mandatory Use an inverter that conforms to the specifications of power supply and three-phase induction motor being used.
! E6581301! 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. Method of lubricating load mechanisms Operating an oil-lubricated reduction gear and gear motor in the low-speed areas will worsen the lubricating effect.
! E6581301! 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. 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.
! E6581301! 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). When you cannot select the proper characteristics install a circuit interrupting fuse between the MCCB2 and the INV1.
! E6581301! (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.
! 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. 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. 1 Prohibited • Operate under the environmental conditions prescribed in the instruction manual. Operation under any other conditions may result in malfunction.
! E6581301! • Do not install in any location that is subject to large amounts of vibration. Note: If the VF-AS1 Inverter is installed in a location that is subject to vibration, anti-vibration measures are required. Please consult with your Toshiba distributor about these measures. 1 • 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.
! 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. If the inverters are horizontally arranged with no space between them (side-by-side installation), remove of the protective cover on top of the inverter.

! 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. The amount of forced air-cooling ventilation required and the necessary heat exchange surface area when operating 1 in a sealed cabinet according to motor capacity are as follows.
! 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. • 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. • Provide shielding and twisted wire for control circuit wiring.
E6581301! 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 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. • Don't place or insert any kind of object into the inverter (electrical wire cuttings, rods, wires). This can result in electric shock or fire.
E6581301 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).
E6581301! • 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. • Tighten the screws on the terminal board to specified torque.

Taking measures to satisfy the CE/UL/CSA standards 9.1 How to cope with the CE standard In Europe, the EMC directive and the low-voltage directive, which took effect in 1996 and 1997, respectively, make it obligatory to put the CE mark on every applicable product to prove that it complies with the directives.
E6581301 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) 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. (If a further noise reduction is required, insert an additional filter described in I-4 on the input side of the inverter.
E6581301 (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. Do not route them in parallel or bind them together, instead cross at right angle. (3) Install the inverter in an enclosed steel cabinet, it is more effective in limiting the radiation.
E6581301 ■ When an external EMC filter is added (1) Additional external EMC filters have the further effect of suppressing conduction and radiation noises.

! E6581301! 13.2 Method of resetting causes of trip Do not reset the inverter when tripped because of a failure or error before eliminating the cause. Resetting the tripped inverter before eliminating the problem causes it to trip again. For recovering inverter from trip status, (1) By turning off the power (Keep the inverter off until the LED turns off.) Refer to Section 6.33.2 (inverter trip retention selection H ) for details.
! E6581301! 13.3 If the motor does not run while no trip message is displayed... If the motor does not run while no trip message is displayed, follow these steps to track down the cause. The motor does not run. YES : NO Is the 7-segment LED extinguished? : Check the power supply and the MCCB. Is power being supplied normally? Supply the power normally. • Check the cooling fan. • Contact your Toshiba distributor. Is OQHH blinking? Main circuit power is undervoltage. Check the input voltage.
! E6581301! 13.4 How to check other troubles The following table provides a listing of other troubles, their possible causes and remedies. Troubles The motor runs in the wrong direction. The motor runs but its speed does not change normally. The motor does not accelerate or decelerate smoothly. A too large current flows into the motor. The motor runs at a higher or lower speed than the specified one. The motor speed varies during operation. Some or all of seven keys on operation panel don't work.
! E6581301! 14. Inspection and maintenance Warning • 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. Mandatory • Before inspection, perform the following steps.
