Page 4: General Operation
General Operation • Never disassemble, modify or repair. This can result in electric shock, fire and injury. For repairs, call your sales distributor. Disassembly prohibited • Never remove the front cover when power is on or open door if enclosed in a cabinet. The unit contains many high voltage parts and contact with them will result in electric shock.
Page 5 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 6 • Electrical installation work must be done by a qualified expert. Connection of input power by someone who does not have that expert knowledge may result in fire or electric shock. • Connect output terminals (motor side) correctly. If the phase sequence is incorrect, the motor will operate in reverse and that may result in injury.
Page 7: Maintenance And Inspection
• Observe all permissible operating ranges of motors and mechanical equipment. (Refer to the motor's instruction manual.) Not observing these ranges may result in injury. Prohibited When sequence for restart after a momentary failure is selected (inverter) • Stand clear of motors and mechanical equipment. If the motor stops due to a momentary power failure, the equipment will start suddenly after power recovers.

Page 25: Notes On The Application
1.4.1 Motors When the VF-FS1 and the motor are used in conjunction, pay attention to the following items. 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-...
Page 26 Low loads and low inertia loads The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of 50 % or under of the load percentage, or when the load's inertia moment is extremely small. If that happens reduce the carrier frequency.
Page 27 Braking motor When using a braking motor, if the braking circuit is directly connected to the inverters's output terminals, the brake cannot be released because of the lowered starting voltage. Therefore, when using a braking motor, connect the braking circuit to the inverter's power supply side, as shown in the figure below.
Page 28 Power factor correction capacitor Power factor correction capacitors cannot be installed on the output side of the inverter. When a motor is run that has a power factor correction capacitor attached to it, remove the capacitors. This can cause inverter malfunction trips and capacitor destruction. Operating at other than rated voltage Connections to voltages other than the rated voltage described in the rating label cannot be made.
Page 29 Disposal If an inverter is no longer usable, dispose of it as industrial waste. 1.4.3 What to do about the leak current Current may leak through the inverter's input/output wires because of insufficient electrostatic capacity on the motor with bad effects on peripheral equipment. The leakage current’s value is affected by the carrier frequency and the length of the input/output wires.
Page 30 (2) Affects of leakage current across lines Power supply Leakage current path across wires Thermal relays The high frequency component of current leaking into electrostatic capacity between inverter out- put wires will increase the effective current values and make externally connected thermal relays operate improperly.
