Function/Purpose, etc.
This is used to improve the input power factor of the inverter power supply, reduce harmonics or
suppress external surges.
Install this option when the power supply capacity is 500 kVA or more and the power supply capacity is
10 times or more than that of the inverter's capacity, or when a distortion-generating source such as a
thyristor or a large-capacity inverter is connected to the same wiring leads.
The effect of this option changes according to the impedance of the reactor. Consult us separately for
details.
The DC reactor is more effective than the input reactor in improving the power factor. We recommend
joint use of the input reactor, that is effective in suppressing external surges, when facilities where the
inverter is to be applied require high reliability.
●
This is effective in preventing radio wave interference on audio equipment used near the inverter.
●
Install it on the input side of the inverter.
●
This option is effective in attenuating only specific frequency bands. It is useful as a noise countermeasure
for specific AM radio stations (where radio waves are weak, for example, in mountain areas).
●
Current leakage increases as it is a capacitor type. Avoid use of many of these options when an ELCB
is installed on the power supply side.

External Surge Suppression
●
This is effective in preventing radio wave interference on audio equipment used near the inverter.
●
This is also effective in reducing noise on the input side and output side of the inverter.
●
It has attenuation characteristics of several dB from AM radio bands through to frequency bands up to 10 MHz.
This high-attenuation type EMC noise filter takes up little space, and adopts a system (foot mount or side
mount) that mounting on the rear or side of the inverter (separate-standing for large-capacity class models).
This operation is used when sudden deceleration or stops are frequently performed, or when the
deceleration time must be shortened on loads having a large inertia.
This resistor is for taking up energy during power generation braking.
On systems that run 400 V class general-purpose motors by voltage-type PWM system inverters using
ultra high-speed switching devices (e.g. IGBT), surge voltage, that is dependent on cable length, cable
laying methods, cable constants, and other factors, sometimes causes the insulation of the motor winding
to deteriorate. For this reason, measures for suppressing surge voltage are performed by installing a DC
reactor or surge suppression filter on the inverter output end where the insulation-reinforced motor is used.
Control power need not be input separately as it is supplied internally on the inverter from the main
circuit power supply.
Use this option when backing up only by the control power supply when the main circuit is shut off. This
is +24 VDC output common to both 200 and 400 V models. (Type : CPS001Z)
This operation panel unit is for extension. It is provided with an LED display, RUN/STOP key, UP/DOWN key,
monitor key, and enter key. Setup parameters for three inverters can be stored to this panel. (Type : RKP002Z)
Connector cable for LED extension
Has a built-in frequency type, frequency setter and RUN-STOP (forward run, reverse run) switch. (model type: CBVR-7B1)
The AP Series that supports various applied control in combination with an inverter is also available.
This allows heat generated inside panels to be reduced.

Harmonics are defined as sinusoidal waves that is multiple frequency of
commercial power (base frequency: 50Hz or 60Hz). Commercial power
including harmonics has a distorted waveform.
Some electrical and electronic devices produce distorted waves in their
rectifying and smoothing circuits on the input side. Harmonics produced by a
device influence other electrical equipment and facilities in some cases (for
example, overheating of phase advancing capacitors and reactors).

Built-in options
200 V - 7.5 kW or less, and 400 V - 75 kW or less models have a built-in high-attenuation noise filter.
However, use this filter when noise must be suppressed even more.
●
This is effective in preventing radio wave interference on audio equipment used near the inverter.
●
Install it on the input side of the inverter.
●
It is effective in attenuating in a wide range from AM radio bands through to 10 MHz.
●
Use it when equipment that is susceptible to noise is installed nearby.
This operation panel unit is for extension or mounting on the inverter body. Its 11-character, 8-line
“hiragana” and Kanji display facilitates parameter setup. The dedicated cable for the LCD extension
panel is required for connecting it to the inverter. (Type : RKP004Z)
Measures for suppressing higher harmonics
The leakage of a harmonic current from an inverter can be restricted by
connecting an input AC reactor (ACL) on the input side of the inverter or a DC
reactor (DCL) to the DC section of the inverter.
A PWM converter that shapes the waveform of an input current into a
substantially sinusoidal waveform. The leakage of a harmonic current from a
power supply can be restricted by connecting a harmonic suppressing unit (SC7).
A harmonic current can be absorbed by the use of a phase advancing capacitor
unit composed of a phase advancing capacitor and a DC reactor.
For delta-delta connection and delta-Y connection transformers, the effect of 12
pulses can be obtained by distributing the load evenly, and thus currents
containing fifth-order and seventh-order harmonics can be suppressed.
Harmonic currents can also be suppressed by the use of passive (AC) and
active filters.

Selecting the Capacity (model) of the Inverter
Capacity
Refer to the applicable motor capacities listed in the standard specifications.
When driving a high-pole motor, special motor, or multiple motors in parallel, select such an inverter
that the sum of the motor rated current multiplied by 1.05 to 1.1 is less than the inverter's rated output
current value.
Acceleration/deceleration times
The actual acceleration and deceleration times of a motor driven by an inverter are determined by the
torque and moment of inertia2 of the load, and can be calculated by the following equations.
The acceleration and deceleration times of an inverter can be set individually. In any case, however,
they should be set longer than their respective values determined by the following equations.
Allowable torque characteristics
When a standard motor is combined with an inverter to perform variable speed operation, the motor
temperature rises slightly higher than it normally does during commercial power supply operation. This
is because the inverter output voltage has a sinusoidal (approximate) PWM waveform. In addition, the
cooling becomes less effective at low speed, so the torque must be reduced according to the
frequency.
When constant-torque operation must be performed at low speeds, use a Toshiba VF motor designed
specifically for use with inverters.
Starting characteristics
When a motor is driven by an inverter, its operation is restricted by the inverterÅfs overload current
rating, so the starting characteristic is different from those obtained from commercial power supply
operation.
Although the starting torque is smaller with an inverter than with the commercial power supply, a high
starting torque can be produced at low speeds by adjusting the V/f pattern torque boost amount or by
employing vector control. (200% in sensorless control mode, though this rate varies with the motor
characteristics.) When a larger starting torque is necessary, select an inverter with a larger capacity
and examine the possibility of increasing the motor capacity.
