Precautions for Use
Driving a 400 V
general-purpose
motor
When driving a 400 V general-purpose motor with an inverter using
extremely long wires, damage to the insulation of the motor may occur. Use
an output circuit filter (OFL) if necessary after checking with the motor
manufacturer. Fuji motors do not require the use of output circuit filters
because of their reinforced insulation.
Torque
characteristics and
temperature rise
When the inverter is used to run a general-purpose motor, the temperature
of the motor becomes higher than when it is operated using a commercial
power supply. In the low-speed range, the cooling effect will be weakened,
so decrease the output torque of the motor. If constant torque is required in
the low-speed range, use a Fuji inverter motor or a motor equipped with an
externally powered ventilating fan.
Vibration
When an inverter-driven motor is mounted to a machine, resonance may be
caused by the natural frequencies of the machine system.
Note that operation of a 2-pole motor at 60 Hz or higher may cause
abnormal vibration.
* The use of a rubber coupling or vibration-proof rubber is recommended.
* Use the inverter's jump frequency control feature to skip the resonance
frequency zone(s).
In running
general-
purpose
motors
Noise
When an inverter is used with a general-purpose motor, the motor noise
level is higher than that with a commercial power supply. To reduce noise,
raise carrier frequency of the inverter. Operation at 60 Hz or higher can also
result in higher level of wind roaring sound.
High-speed
motors
If the set frequency is set to 120 Hz or more to drive a high-speed motor,
test-run the combination of the inverter and motor beforehand to check for
safe operation.
Explosion-proof
motors When driving an explosion-proof motor with an inverter, use a combination
of a motor and an inverter that has been approved in advance.
Submersible
motors and pumps
These motors have a higher rated current than general-purpose motors.
Select an inverter whose rated output current is higher than that of the
motor.
These motors differ from general-purpose motors in thermal characteristics.
Set a low value in the thermal time constant of the motor when setting the
electronic thermal overcurrent protection (for motor).
Brake motors
For motors equipped with parallel-connected brakes, their power supply for
brake must be supplied from the inverter’s primary circuit. If the power
supply for brake is connected to the inverter's output circuit by mistake, the
brake will not work.
Do not use inverters for driving motors with series-connected brake coils.
Geared motors If the power transmission mechanism uses an oil-lubricated gearbox or
speed changer/reducer, then continuous motor operation at low speed may
cause poor lubrication. Avoid such operation.
Synchronous
motors It is necessary to take special measures suitable for this motor type. Contact
your Fuji Electric representative for details.
In running
special
motors
Single-phase
motors Single-phase motors are not suitable for inverter-driven variable speed
operation. Use three-phase motors.

iv
Environ-
mental
conditions
Installation
location
Use the inverter within the ambient temperature range from -10 to +50°C.
The heat sink and braking resistor of the inverter may become hot under
certain operating conditions, so install the inverter on nonflammable
material such as metal.
Ensure that the installation location meets the environmental conditions
specified in Chapter 8, Section 8.4 "Operating Environment and Storage
Environment."
Installing an
MCCB or
RCD/ELCB
Install a recommended molded case circuit breaker (MCCB) or
residual-current-operated protective device (RCD)/earth leakage circuit
breaker (ELCB) (with overcurrent protection) in the primary circuit of each
inverter to protect the wiring. Ensure that the circuit breaker capacity is
equivalent to or lower than the recommended capacity.
Installing an MC
in the secondary
circuit
If a magnetic contactor(MC)is installed in the inverter's output (secondary)
circuit for switching the motor to commercial power or for any other
purpose, ensure that both the inverter and the motor are completely stopped
before you turn the MC on or off.
Remove a surge killer integrated with the magnetic contactor in the
inverter's output (secondary) circuit.
Installing an MC
in the primary
circuit
Do not turn the magnetic contactor (MC) in the primary circuit on or off
more than once an hour as an inverter failure may result.
If frequent starts or stops are required during motor operation, use terminal
[FWD]/[REV] signals or the RUN/STOP key.
Protecting the
motor
The electronic thermal feature of the inverter can protect the motor. The
operation level and the motor type (general-purpose motor, inverter motor)
should be set. For high-speed motors or water-cooled motors, set a small
value for the thermal time constant.
If you connect the motor thermal relay to the motor with a long wire, a
high-frequency current may flow into the wiring stray capacitance. This
may cause the thermal relay to trip at a current lower than the set value. If
this happens, lower the carrier frequency or use the output circuit filter
(OFL).
Discontinuance of
power-factor
correcting
capacitor
Do not connect power-factor correcting capacitors to the inverter’s primary
circuit. (Use the DC reactor to improve the inverter power factor.) Do not
use power-factor correcting capacitors in the inverter’s output (secondary)
circuit. An overcurrent trip will occur, disabling motor operation.
Discontinuance of
surge killer Do not connect a surge killer to the inverter's output (secondary) circuit.
Reducing noise
Use of a filter and shielded wires is typically recommended to satisfy EMC
Directive.
Refer to Appendices, App. A "Advantageous Use of Inverters (Notes on
electrical noise)" for details.
Measures against
surge currents
If an overvoltage trip occurs while the inverter is stopped or operated under
light load, it is assumed that the surge current is generated by open/close of
the phase-advancing capacitor in the power system.
* Connect a DC reactor to the inverter.
Combina-
tion with
peripheral
devices
Megger test When checking the insulation resistance of the inverter, use a 500 V megger
and follow the instructions contained in the FRENIC-Multi Instruction
Manual (INR-SI47-1094-E), Chapter 7, Section 7.5 "Insulation Test."

v
Control circuit
wiring length When using remote control, limit the wiring length between the inverter and operator panel to 20 m or less and use twisted pair or shielded wire.
Wiring length
between inverter
and motor
If long wiring is used between the inverter and the motor, the inverter may
overheat or trip due to overcurrent because a higher harmonics current
flows into the stray capacitance between each phase wire. Ensure that the
wiring is shorter than 50 m. If this length must be exceeded, lower the
carrier frequency or install an output circuit filter (OFL).
Wire size Select wires with a sufficient capacity by referring to the current value or
recommended wire size.
Wire type Do not share one multi-core cable in order to connect several inverters with
motors.
Wiring
Grounding Securely ground the inverter using the grounding terminal.
Driving
general-purpose
motor
Select an inverter according to the applicable motor ratings listed in the
standard specifications table for the inverter.
When high starting torque is required or quick acceleration or deceleration
is required, select an inverter with one rank larger capacity than the
standard. Refer to Chapter 7, Section 7.1 "Selecting Motors and Inverters"
for details.
Selecting
inverter
capacity
Driving special
motors Select an inverter that meets the following condition: Inverter rated current > Motor rated current
Transpor-
tation and
storage
When transporting or storing inverters, follow the procedures and select locations that meet the
environmental conditions listed in the FRENIC-Multi Instruction Manual (INR-SI47-1094-E),
Chapter 1, Section 1.3 "Transportation" and Section 1.4 "Storage Environment."
