Page 2: Safety Precautions
E6581381 Safety precautions The items described in these instructions and on the inverter itself are very important so that you can use the inverter safely, prevent injury to yourself and other people around you as well as to prevent damage to property in the area.
Page 3: General Operation
E6581381 General Operation Warning See item • 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 4 Operation cannot be stopped immediately by the inverter alone, thus risking an accident or injury. • All options used must be those specified by Toshiba. 1.4.4 The use of any other option may result in an accident.
Page 5 E6581381 Warning See item • 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 6: Maintenance And Inspection
E6581381 Caution See item • 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.

Page 24: Notes On The Application
E6581381 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. 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 overheating and Mandatory fire.
Page 25 E6581381 Low loads and low inertia loads The motor may demonstrate instability such as abnormal vibrations or overcurrent trips at light loads of 5 % or under of the load percentage, or when the load's inertia moment is extremely small. If that happens reduce the carrier frequency.
Page 26 E6581381 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 27 E6581381 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.
Page 28: What To Do About The Leak Current
E6581381 Disposal If an inverter is no longer usable, dispose of it as industrial waste. 1.4.3 What to do about the leak current Caution Current may leak through the inverter's input/output wires because of insufficient electrostatic capacity on the motor with bad effects on peripheral equipment.
Page 29 E6581381 (2) Affects of leakage current across lines Thermal relays Inverter 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.
Page 30: Instruction Manual
E6581381 CT and ammeter If a CT and ammeter are connected externally to detect inverter output current, the leak current's high frequency component may destroy the ammeter. If the wires are more than 50 meters long, it will be easy for the high frequency component to pass through the externally connected CT and be superimposed on and burn the ammeter with models having motors of low rated current (several A(ampere) or less), especially the 400V class low capacity (5.5kW or less) models, because the leak current will increase in proportion to the motor's rated current.
Page 31 If the VF-FS1 Inverter is installed in a location that is subject to vibration, anti-vibration measures are required. Please consult with Toshiba about these measures. • If the VF-FS1 Inverter is installed near any of the equipment listed below, provide measures to insure against errors in operation.
Page 32 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 33 E6581381 Calorific values of the inverter and the required ventilation About 5% of the rated power of the inverter will be lost as a result of conversion from AC to DC or from DC to AC. 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 34 E6581381 • Separate the input (power) and output (motor) wires of the main circuit. Do not place them in the same conduit, do not run them parallel, and do not bundle them. • Ground the inverter ground terminals ( • Install surge suppressor on any magnetic contactor and relay coils used around the inverter. •...
Page 35: Connection
E6581381 2. Connection 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 36: Standard Connections
E6581381 Warning • Ground must be connected securely. If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or current leak occurs. Be Grounded Caution • Do not attach devices with built-in capacitors (such as noise filters or surge absorber) to the output (motor side) terminal.

Page 177 E6581381 6.21.2 Using the RS485 Setting the communication functions Setting commands and frequencies by communications has priority over sending commands from the operation panel or the terminal board. Command/frequency setting by communications can therefore be enabled, irrespective of the setting in the command mode () or the frequency setting mode (). When inverters are connected to each others, however, in order for slave inverters to recognize frequency signals from the master inverter as frequency commands, the frequency setting mode selection 1 parameter () provided for each slave inverter needs to be set to 4 (serial communications).

All Toshiba inverters are CE- marked in accordance with the standard EN/IEC 61800-5-1 specified by the low-voltage directive, and can therefore be installed in machines or systems and imported without problem to European countries.
Page 199: Compliance With Ul Standard And Csa Standard
E6581381 9.1.4 Measures to satisfy the low-voltage directive When incorporating the inverter into a machine or system, it is necessary to take the following measures so that the inverter satisfies the low-voltage directive. Install the inverter in a cabinet and ground the inverter enclosure. When doing maintenance, be extremely careful not to put your fingers into the inverter through a wiring hole and touch a charged part, which may occur depending on the model and capacity of the inverter used.

Unusual motor vibration, noise or overheating 7. Adhesion or accumulation of foreign substances (conductive substances) Cautions about cleaning To clean the inverter, wipe dirt off only its surface with a soft cloth but do not try to remove dirt or stains from any other part.
Page 242 E6581381 5. If no power is supplied to the inverter for a long time, the performance of its capacity electrolytic capacitor declines. When leaving the inverter unused for a long time, supply it with electricity once every two years, for 5 hours or more each, to recover the performance of the capacity electrolytic capacitor.
Page 243 Note: The operation time is helpful for roughly determining the time of replacement. For the replacement of parts, contact your nearest Toshiba inverter distributor. For safety’s sake, never replace any part on your own. (Parts replacement alarms can be known by monitor and alarm output, if it is set.
