    ■Handling in general Never disassemble, modify or repair the inverter. Its disassembly could cause an electric shock, afire or an injury. Request your TOSHIBA dealer for repair. Never Disassemble -Never open the front cover of the inverter(or the door of the cabinet in which the inverter is installed) when the inverter is energized, or you could get a shock since a high voltage is applied to certain portions of it.

  • Page 4

    -Do not install or operate the inverter if it is damaged or any part is missing from it. Operating the inverter in a defective condition could lead to a shock or a fire. Request your Toshiba dealer for repair. -Do not put any inflammable material near the inverter, or it could catch a Prohibited fire if the inverter sparks because of a breakdown, etc.

  • Page 5

    ■Wiring -Do not connect the power cable to any output terminal (U/T1, V/T2 or W/T3 on the motor side), or the inverter could break down and cause a fire. -Do not connect a resistor to any D.C. terminal (between PA and PC or PO and PC), or the inverter could cause a fire.

  • Page 6

    ■ About operation -Do not touch any inverter's terminal when it is energized even if the motor is standstill, or you could get a shock. -Do not operate switches with a wet hand or not put a wet cloth on the inverter, or you could get a shock.

  • Page 7

    About inspection and maintenance -Do not replace any part yourself, or you could get a shock or an injury, or cause a fire. Request your Toshiba dealer for replacement of parts. Prohibited -Carry out inspection and maintenance on a daily basis. Failure to do so to find defects in the inverter could lead to accidents.

    So, reduce the motor's output below the rated load when operating it in a low speed range. If you wish to operate a motor continuously at the rated torque, then use a Toshiba VF motor designed specially for use in conjunction with an inverter. When the inverter is combined with a VF motor, its overload protection level needs to be changed to "VF motor"...

    In circuit configuration 2, the brake is turned on and off by means of a low-speed signal OUT1. However, for certain applications, it is recommended to use a low-speed detection signal (function of terminal OUT1) to turn on and off the motor. Contact your Toshiba dealer before designing a system.

    1.4.2 Notes on inverters Over-current protective function        The inverter has an over-current protective function. The current for this protection is adjusted to the maximum current rating of the applicable motors by default. Therefore, when the inverter is used to control a motor with a relatively small capacity, it is necessary to readjust the over-current protection level and the electronic thermal protective function.

    Use parameter  to lower the PWM carrier frequency. 2. Use high frequency-ready ground leakage breakers (e.g., Esper Mighty series(manufactured by Toshiba Schneider Electric Ltd.)). When these ground leakage breakers are installed, there is no need to lower the PWM carrier frequency.

  • Page 25

    Power supply Measures to be taken: 1. Use the electronic thermal function provided for the inverter. Use parameter , to set the electronic thermal function. 2. Lower the PWM carrier frequency, though this results in an increase in motor magnetic noise. Use parameter ...

    1.4.4 Notes on installation Installation environment ■ The VF-P7 inverter is an electronic control device. Therefore, due consideration should be given to its installation environment. -Do not put any inflammable material near the inverter, or it could catch a fire if the inverter sparks because of trouble.

  • Page 27

    50℃ Note) The inverter produces heat. When installing it in a cabinet, consider its ventilating condition and internal space. The VF-P7 can be used at ambient temperatures of up to 50℃. ・ Do not install the inverter in any place subject to vibration.

  • Page 28

    Failure to do so could lead to injury to persons since it has no emergency stop function. - Do not use any optional devices other than those designated by Toshiba. The use of improper devices could lead to accidents.

  • Page 29

    ■Calorific values of inverters and amount of air to be ventilated The VF-P7 series of inverter loses about 5% of energy when switching electric currents from AC, DC, then to AC. To limit a temperature rise due to this energy loss, it is necessary to forcefully ventilate and cool down the cabinet in which the inverter is installed.

  • Page 30

    ■Control panel designed in consideration of possible influences of noise Inverters produce high-frequency noise. To avoid influences of noise, measures must be taken in designing a control panel. Here are some examples of measures against noise. ・ Separately install the wires of the main circuit and those of the control circuit. their wires in the same duct or in parallel with each other, and do not bind them together.

  • Page 31

    ■Heat-sink going out attachment(simple type) To install a standard VF-P7 designed for 200V-37kW motor or larger or 400V-45kW motor or larger, you can choose a one from next two forms. (1) Normal attachment (Whole the inverter is in the cabinet) (2) Heat-sink going out (the cabinet) attachment(simple type) Heat-sink going out attachment reduces the generation of heat inside the cabinet.

  • Page 32

    2. Connection ・Never disassemble, modify or repair the inverter. Its disassembly could cause an electric shock, a fire or an injury. Request your Toshiba dealer for repair. Disassemble ・Do not put or insert anything (e.g., an electric cable, a bar or a steel wire) into the inverter, or the inverter could cause a shock or a fire.

  • Page 33

    ・ Do not connect any device or unit with a built-in capacitor (noise filter, surge suppressor, etc.) to output terminals (on the motor side), or it could cause the risk of a fire. Prohibited ■Prevention of radio noise Prevent interference, such as radio noise, separately install and bind cables connected to the power supply-side terminals (R/L1, S/L2 and T/L3) of the main circuit and those connected to the motor-side terminals (U/T1, V/T2 and W/T3).

    (2) Integral gain Integral (I) gain () is integral gain for PID control. This gain acts to make the deviation which remains in proportional operation (remained deviation offset) to zero. Setting this parameter at a large value gives smaller remained deviation offset, but setting at a too large value may result in an unstable phenomenon like hunting.

    12. 2 Method of resetting causes of trip If the inverter trips because of trouble or malfunction, remove the cause of trip before resetting it. If the inverter is reset as the cause of trip remaining with it, it again trips in spite of resetting. For recovering inverter from trip status, (1) Cut off power supply (until nothing appears on the LED display).

    13. Regular inspection and maintenance ・Be sure to inspect the inverter regularly. If the inverter is used without regular inspection, it may cause trouble or accident because sign of disorder or failure is missed. ・Complete the following steps before proceeding to inspection. 1 Cut off power supply (turn off the inverter).

  • Page 246

    13. 2 Periodical inspection Make periodical inspection at intervals of three or six months depending on operating conditions. ・Complete the following steps before proceeding to periodical inspection. 1 Cut off power supply (turn off the inverter). 2 10 minutes or more after power cut off, check to see if the charge indicator lamp is turned off.

    13. 3 When making a service call 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, let us know the contents of the rating plate on the right side of the inverter and connection of options besides details of the trouble.

  • Page 249: Warranty

    14. Warranty The inverter is warranted by Toshiba for repair and adjustment free of charge based on the following conditions. 1. Warranty is limited to the inverter's main body only. 2. If the inverter becomes out of order or damaged under the usual operating condition within 12 months after delivery, it will be repaired free of charge by Toshiba.
