Connection with Peripheral Devices

Peripheral devices necessary for driving the FR-F700 series inverter are indicated below.

Three-phase AC power supply

Use within the permissible power supply
specifications of the inverter.

(Refer to page 7.)

Moulded case circuit
breaker (MCCB)
or earth leakage circuit
breaker (ELB), fuse

The breaker must be selected carefully since
an in-rush current flows in the inverter at
power on.

(Refer to page 57.)

Magnetic contactor(MC)

Install the magnetic contactor to ensure safety.
Do not use this magnetic contactor to start and
stop the inverter.
Doing so will cause the inverter life to be shorten.

(Refer to page 57.).

Reactor (FR-HAL, FR-HEL)

Reactors (option) should be used when power
harmonics measures are taken, the power factor
is to be improved or the inverter is installed near a
large power supply system (1000kVA or more).
The inverter may be damaged if you do not use
reactors.
Select the reactor according to the model.
For the 55K or less, remove the jumpers across
terminals P/+-P1 to connect to the DC reactor.

(Refer to page 51.).

PLC

RS-485 terminal block

The inverter can be
connected with computers
such as PLC.
It supports Mitsubishi inverter
protocol and Modbus-RTU
(binary) protocol.

Inverter (FR-F700)

The life of the inverter is influenced by ambient temperature.
The ambient temperature should be as low as possible within
the permissible range. (Refer to page 8.) This must be noted
especially when the inverter is installed in an enclosure.
Wrong wiring might lead to damage of the inverter. The control
signal lines must be kept fully away from the main circuit to
protect them from noise.

Motor

Why Can the Inverter Save Energy?

The load torque of a motor-driven machine generally changes depending on speed. On the other hand, motor output is
proportional to the product of load torque and speed as indicated in the following formula, and therefore, necessary motor
output varies with speed.

Motor output P = T

× N/(9550 × η) [kW]

T : Motor shaft-equivalent load torque [N·m]
N : Motor speed [r/min]
η : Machine efficiency

When this motor is operated by the inverter, the inverter output provides the frequency f appropriate to the motor speed,
and the then output voltage V is determined by a "V/f = constant" pattern in the case of a constant-torque load.
For example, when the motor is operated at middle speed, f, i.e. output voltage V, decreases, and therefore, the inverter
output power V × I reduces if the output current I is constant.
Proportionately, the inverter input current decreases and the power consumption reduces. Namely, when the motor output
reduces, the input power of the inverter also decreases as a matter of course.
The fundamental principle of energy saving by the inverter is to eliminate wasted power consumption by minimizing loss
caused by the other devices and minimizing the motor output as compared to the other system (for example, commercial
power supply operation or secondary resistance control of wound-rotor motor). A maximum energy saving effect is
produced on a fan, pump or like by the variable-torque load characteristic that reduces load torque as speed decreases.

Motor speed control enables substantial energy-saving operation as compared to commercial power supply operation.

For example, when a 15kW motor is operated at 60% air volume and
the power charge is 17 yen/kW·h, the power charge as much as below

*1. The applied motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor.
*2. The rated output capacity indicated assumes that the output voltage is 220V for 200V class and 440V for 400V class.
*3. When operating the inverter with the carrier frequency set to 3kHz or more, the carrier frequency automatically decreases if the inverter output

current exceeds the value in parenthesis of the rated current. This may cause the motor noise to increase.

*4. The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty,

allow time for the inverter and motor to return to or below the temperatures under 100% load.

*5. The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range.

However, the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply.
*6. The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables).
*7. When the hook of the inverter front cover is cut off for installation of the plug-in option, the inverter changes to an open type (IP00).
*8. FR-DU07 : IP40 (Except for the PU connector).

CAUTION

To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables.

Connected to the AC power supply terminals R/L1 and S/L2. To retain the alarm display and
alarm output, apply external power to this terminal.
Connect the brake unit (FR-BU, BU, MT-BU5), power regeneration common converter (FR­CV), power regeneration converter (MT-RC) or high power factor converter (FR-HC, MT-HC).
For the 55K or less, remove the jumper across terminals P/+ - P1 and connect the DC reactor.
(For the 75K or more, a DC reactor is supplied as standard.)

Turn on the STF signal to start forward rotation and turn it off to
stop.
Turn on the STR signal to start reverse rotation and turn it off to
stop.

Turn on the STOP signal to self-hold the start signal.

Turn on the JOG signal to select Jog operation (initial setting) and turn on the start signal (STF
or STR) to start Jog operation.
Turn on the RT signal to select second acceleration/deceleration time.
When the second function such as "second torque boost" and "second V/F (base frequency)"
are set, turning on the RT signal selects these functions.
Turn on the MRS signal (20ms or more) to stop the inverter output.
Use to shut off the inverter output when stopping the motor by electromagnetic brake.
Used to reset alarm output provided when protective function is activated. Turn on the RES
signal for more than 0.1s, then turn it off.
Recover about 1s after reset is cancelled.
Terminal 4 is made valid only when the AU signal is turned on. (The frequency setting signal
can be set between 4 and 20mADC.)
Turning the AU signal on makes terminal 2 (voltage input) invalid.
AU terminal is used as PTC input terminal (thermal protection of the motor). When using it as
PTC input terminal, set the AU/PTC switch to PTC.

When the CS signal is left on, the inverter restarts automatically at power restoration. Note that
restart setting is necessary for this operation. In the initial setting, a restart is disabled.

Common terminal for contact input terminal (sink logic) and terminal FM. Common output
terminal for 24VDC 0.1A power supply (PC terminal). Isolated from terminals 5 and SE.
When connecting the transistor output (open collector output), such as a programmable
controller (PLC), when sink logic is selected, connect the external power supply common for
transistor output to this terminal to prevent a malfunction caused by undesirable currents. Can
be used as 24VDC 0.1A power supply. When source logic has been selected, this terminal
serves as a contact input common.

When connecting the frequency setting potentiometer at an initial
status, connect it to terminal 10.
Change the input specifications when connecting it to terminal 10E.

Inputting 0 to 5VDC (or 0 to 10V, 4 to 20mA) provides the maximum output frequency at 5V
(10V, 20mA) and makes input and output proportional. Use Pr.73 to switch from among input 0
to 5VDC (initial setting), 0 to 10VDC, and 4 to 20mA.
Voltage input: Input resistance 10kΩ ± 1kΩ Maximum permissible voltage 20VDC
Current input: Input resistance 250Ω ± 2% Maximum permissible current 30mA
Inputting 4 to 20mADC (or 0 to 5V, 0 to 10V) provides the maximum output frequency at 20mA
(5V, 10V) makes input and output proportional. This input signal is valid only when the AU
signal is on (terminal 2 input is invalid). Use Pr.267 to switch between the input 4 to 20mA and 0
to 5VDC, 0 to 10VDC (initial setting).
Voltage input: Input resistance 10kΩ ± 1kΩ Maximum permissible voltage 20VDC
Current input: Input resistance 250Ω ± 2% Maximum permissible current 30mA
Inputting 0 to ±5 VDC or 0 to ±10VDC adds this signal to terminal 2 or 4 frequency setting
signal. Use Pr.73 to switch between the input 0 to ±5VDC and 0 to ±10VDC (initial setting).
Input resistance 10kΩ ± 1kΩ, Maximum permissible voltage ± 20VDC
Common terminal for frequency setting signal (terminal 2, 1 or 4) and analog output terminal
AM. Do not earth (ground).

When the STF and STR
signals are turned on
simultaneously, the stop
command is given.

10VDC, permissible load
current 10mA.
5VDC, Permissible load
current 10mA.
