Caution Use an inverter that conforms to the specifications of power supply and three-phase induction motor being used.
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.
Page 32: Inverters
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 41 E6581442  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 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.

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
E6581442 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.
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.
Page 235 E6581442  When an external EMC filter is added (1) Additional external EMC filters have the further effect of suppressing conduction and radiation noises. Use the recommended EMC noise filter specified in Table 3. This combination of inverter and filter was used when examining the inverter for compliance with the EMC directive.

Type : NF series 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.
Page 240: Measures To Be Taken To Satisfy The Ul/Csa Standards
E6581442 Measures to be taken to satisfy the UL/CSA standards All VF-AS1 series inverters are certified by UL and CSA, and have nameplates with UL and CSA markings. 9.2.1 Caution in installing the inverter A UL certificate was granted on the assumption that the inverter would be installed in a cabinet. Therefore, install the inverter in a cabinet and if necessary, take measures to maintain the ambient temperature (temperature in the cabinet) within the specified temperature range.

Page 242: Compliance With Safety Standards
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.
