INSPECTION UPON RECEIPT
1·1 Unpacking:
Verify the following: (If you find any defect, contact Toshiba or the local supplier.)
(1) Check for shipping damage.
(2) Verifythat the rated capacity and voltage conform to your orderrequirements.
Please refer to "Oescription of Type-Form" on the following page.
1
-2 Storage:
If the inverter will not be used immediately upon receipt, and will be put into
temporary
or long-time storage, observe the following cautions:
(1) Avoid storage in high temperature, high humidity,and areas which are dustyor
contain metal particles. Select a well-ventilated place for storage.
(2) If the inverter has printed circuit boards provided with an electrostaticcharge
prevention cover, do not remove them while in storage. When powering upthe
inverter, be sure to take off the electrostatic covers on the printed circuits
boards.
(3) If the inverter powered up for more than 6 months, it should be electrically
connected on asemi¥annual basis
to maintain the electrical characteristics of
the large--capacity electrolytic capacitors. At the same time, check
the
functionality of the inverter. If left unused for a long period of time, the large~
capacity electrolytic capacitor bank will deteriorate, and will require
reconditioning. (For its inspection, see section 11-5.)
1-3 Warranty:
Should the dr'lve unH fail to operate or is damaged for any reason related to our
design, manufacture and testing, it will be repaired
or replaced free of charge,
provided that such failure or damage
has occurred during the following warranty
period:
The warranty period of this inverter is 18 months from the date of shipment
or 12
months from the start of operation, whichever is shorter. However, the repair or
replacement of the drive will
be charged tothe customerduring the warrantyperiod if
failure
or damage has been caused by the following:
(1) A wiring or operational error, or unreasonable repair or unauthorized
modification;
(2) Unit damaged by a fall after purchase or during transportation;
(3) Fire, acid, corrosive gas, earthquake, wind, flood, lightning, abnormal voltage
and/or voltage spikes,
or any other natural disaster or an act of God;
(4) Use for a purpose other than those designed by the manufacturer;
(5) The warranty will be limited should the enclosed self addressed stamped
warrantycard not be returned
tothe manufacturer, seethe ExtendedWarranty
Registration card
in the front of this manual.

Chapter II
Characteristics of TOSVERT-130H/H1
1. The drive's quiet operation closely approximates the motor smoothly operating
across the sinusoidal AC power line:
(1) The TOSVERT-130Hl Series allows low-noise operation by using IGBT's
(Insulated Gate Bipolar Transistors - a Bipolar type MOS-FET), a new high-
frequency high power switching device developed by Toshiba. On the other
hand, the TOSVERT-130H Series uses conventional G-TR's (Bipolar type
transistors), and Toshiba's custom designed sine wave
PWM method, which
also reduces motor noise. If the TOSVERT-130H is configured with a noise
filter, the motor noise is reduced to nearly that of the TOSVERT-130Hl. This
noise level is about 1
OdB(A) lower than the conventional PWM transistorized
inverters:
1) TOSVERT-130H1 Series:
[>--1 TOSVE RT -f30Hf I
2) TOSVERT-130H Series:
@ (Low noise)
C>---1 TOSVERT -DOH H Fil ter I---@INOise reduced by oplional filler)
(Option)
(2) The carrier frequency for the sine wave PWM control can be changed to
prevent resonance 'In the mechanical system. This allows for smoother and
quieter operation for a wider range of applications.
2. The inverter is especially designed for energy-saving systems, such as an air
handling equipment in buildings, and fans, pumps, blowers, etc.
(1) Energy-Saving Control:
1) Energy-saving voltage/frequency 0I/F) pattern adjustments have been
provided.
2) Energy-saving operation can be automatically selected.
(2) To enable continuous operation of the inverter under adverse powersources
and load conditions,
the following advanced functions are provided as the
standard features:
1) Automatic restart after instantaneous power failures.
2) Automatic restart in case of fault, for up to 5 times, in the event of
overcurrent.
3) Stall Protection.
4) Soft stall control (Selectable between overload trips).
5) Deceleration limit control.
6) Ground fault.
(3) Easy operation from external control circuits.
1) 6 types of frequency reference signals are standardly available for
selection:
o
3K ohm potentiometer (manual operation)
o 0 - 10 (12) V OC
o 0 - 5V DC
o 4 - 20mA DC
o 0 - 20mA DC
o Input resistance 0 - 135 ohm
2-1

2) PI Control (set point control option) aHows automaticcontrol of delivery
pressure and flow rate of fan, pump and blower.
3) The upper and lower limit output frequency can be preset. When the
output frequency has reached its'upperorlowerlimit,
an open collector
transistor output is available 10r external use in each case.
(4) In case 011ault, a Form C contact signal (dry contact) is activated.
(5) Acceleration and deceleration time can be separately selected within the
range of
0.1 to 300 seconds.
3. Easy Start-up
(1) By using the monitorfunction, thevarious inverters parameters(invertermode,
inverterstatus, current level, etc.) can be read from the builHn digitalindicator
(4 digit. 7 segment LED).
(2) Adjustmentscan be madefrom thefront ofthe inverterthrough asmalldooron
the operation panel, and read digitally on the digital LED indicator by
depressing the monitor functions button.
1) Voltage/Frequency(II /F) patterns can be easilyselected theV/Fpattern
rotary selector switch.
o 14 V
/F patterns
o 2 Energy-saving patterns
2) By adjusting the potentiometers (acceleration/deceleration time,
upper/lower limits, etc.), the monitorfunction is automaticallyactivated,
and the set value of the potentiometer is displayed
on the digital
indicator when selected.
11 an illegal/abnormal value is set, the built-in
alarm system alerts the operator by flashing the display on the digital
indicator. (e.g.-upper limit is incorrectly set lower than lower limit
setting).
3) A reset push-button switch is provided on the printed circuit board, and
can
be operated through the small door of the control panel. Reset
terminals are also provided for external reset (dry contact).
4.
Diagnostic and Protection feature
(1) In an instantaneous powerfailure, the inverter operates continuously ifpower
recovers within 30 msec.
(2) Grounding fault protection is assured as a standard function (optional in
Foreign models)
(3) Standard protectivefunctions also includestall prevention, overcurrent, over-
load, short-circuit, overvoltage, undervoltage. overheat and internal fusing.
(4) As anotherstandard function, a current limit circuit is included which limitsthe
load current automatically at the time of overcurrent.
(5) A voltage limit circuit is also provided standardized for automatic prevention
over voltage on the
DC voltage in the event of overhauling loads with rapid
deceleration times.
(6)
In the event of fault, thecause of the fault flickers onthe digital LED indicator.
Also, the monitor function allows you to read out the inverter status from
memory for diagnosis of the fault.
(7) Acharge lamp LED is provided to indicate that the main DC capacitor bankis
charged.
