Wiring the Main Cir cuits
This section describes wiring connections for the main circuit inputs and outputs.
Wiring Main Circuit Inputs
Observe the following precautions for the main circuit power supply input.
Installing a Molded-case Circuit Breaker
When connecting the power input terminals (R/L2, S/L2 and T/L3) and power supply via a mo lded-case circuit breaker (MCCB) observe that the circuit breaker is suitable for the Inverter.
•
Choose an MCCB with a capacity of 1.5 to 2 times the Inverter's rated current.
•
For the MCCB's time characteristics, be sure to consider the Inverter's overload protection (one minute at
120% of the rate d output current ).
•
If the same MCCB is to be used for more than one Inverter, or other devices, set up a sequence, that the
powersupply will be turned OFF by a fault output, as shown below.
Inverter
Power supply
Fault out-
put (NC)
* For 400-V class Inverters, connect a 400/200-V transformer.
Fig 2.6 MCCB Installation
Installing a Ground Fault Interrupter
Inverter outputs use high-speed switching, so high-frequency leakage current is generated . Therefore, at the
Inverter primary side, use a ground f ault interru pter to detec t only the le akage current in th e freque ncy range
that is hazardous to humans and exclude high-frequency leakage current.
•
For the special-purpose ground fault interrupter for Inverters, ch oose a gr ou nd fault interrupter with a sensitivity amperage of at least 10 mA per Inverter.
•
When using a general ground fault interrupter, choose a ground fault interrupter with a sens itivity amperage of 200 mA or more per Inverter and with an operating time of 0.1 s or more.
Installing a Magnetic Contactor
If the power supply for the main circuit is to be shut off during a sequence, a magnetic contactor can be used.
When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the Inverter,
however, the regenerative braking does not work and the Inverter will coast to stop.
•
The Inverter c an b e start ed a nd st oppe d by o penin g an d clos ing th e ma gnet ic c ontac tor o n th e pri mary si de.
Frequently opening and closing the magnetic contactor, however, may cause the Inverter to break down.
Start and stop the Inverter at most once every 30 minutes.
2

Page 46
•
When the Inverter is operated with the Digital Operator, automatic operation cannot be perfor med after
recovery from a power interruption.
•
If a Braking Unit and a Braking Resistor Unit are used, program the sequence so that the magnetic contactor is turned OFF by the contact of the Braking Resistor Unit's thermal overload relay.
Connecting Input Power Supply to the Terminal Block
Input power supply can be connected to any terminal R, S or T on the terminal block; the phase sequence o f
input power supply is irrelevant to the phase sequence.
Installing an AC Reactor
If the Inverter is connected to a large-capacity power transformer (600 kW or more) o r the phase advancing
capacitor is switched, an excessive peak current may flow through the input power circuit, causing the con verter unit to break down.
To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reactor connection terminals (for units from 22 kW the DC reactor is standard).
This also improves the po wer factor on the power supply side.
Installing a Surge Absorber
Always use a surge absorber or diode for inductive loads near the Inverter. These inductive loads include magnetic contactors, electromagnetic relays, solenoid valves, solenoids and magnetic brakes.
Installing a Noise Filter on Power Supply Side
Install a noise filter to eliminate noise transmitted between the power line and the Inverter.

Do not use general-purpose noise filters. No general
purpose noise filter can effectively suppress noise
generated from the Inver ter .
Observe the following precautions when wiring the main output circuits.
Connecting the Inverter and Motor
Connect output terminals U/T1, V/T2 and W/T3 to motor lead wires U, V and W, respectively.
Check that the motor rotates forward with the forward run command. Switch over any two of the output termi-
nals to each other and reconnect if the motor rotates in reverse with the forward run comm and.
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U/T1, V/T2 and W/T3. If voltage is applied to the output
terminals, the internal circuits of the Inverter will be damaged.
Never Short or Ground Output Te rminals
If the output terminals are touched with bare hands or the output wires come into contact with the Inverter casing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never connect a phase advancing capac itor or LC/RC noise filter to an output circuit. The high-fre quency
components of the Inverter output may result in overheating or damage to these part or may result in damage
to the Inverter or cause other parts to burn.
2

Page 48
Do Not Use an Electromagnetic Switch
Never connect an electromagnetic switch (MC) between the Inverter and motor and turn it ON or OFF during
operation. If the MC is turned ON while the Inverter is operating, a large inrush current will be caused and the
overcurrent protection in the Inverter will operate.
When using an MC to switch to a commercial power supply, stop the Inverter and motor before operating the
MC. Use the speed search function if the MC is operated during operation. If measures for mom entary powe r
interrupts are required, use a delayed release MC.
Installing a Thermal Overload Relay
This Inverter has an electronic thermal protection function to protect the motor from overheating. If, however,
more than one motor is operated with one Inverter or a multi-polar motor is used, always install a thermal
relay (THR) between the Inverter and the motor an d set L1-01 to 0 (no motor protection). The sequence
should be designed so that the contacts of the thermal overload relay turn OFF the magnetic contactor on the
main circuit inputs.
Installing a Noise Filter on Output Side
Connect a noise filter to the output side of the Inverter to reduce radio noise and inductive noise.

Countermeasures against Inductive Noise
As described previously, a noise filter can be used to prevent inductive noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent inductive noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces inductive noise.

Countermeasures Against Radio Interference
Radio noise is generated from the Inverter as well as from the input and output lines. To reduce radio noise,
install noise filters on both, input and output, sides and also install the Inverter in a totally enclosed steel box.
The cable between the Inverter and the motor should be as short as possible.

Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, causing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust
the carrier f reque ncy (set in C 6-01, C6-0 2) as show n in Table 2.6. (For details, refer to Chapter 5 Parameter
Tables.)
Table 2.6 Cable Length between Inverter and Motor
Cable length 50 m max. 100 m max. More than 100 m
Carrier frequency 15 kHz max. 10 kHz max. 5 kHz max.
Ground Wiring
Observe the following precautions when wiring the ground line.
•
Always use the grou nd t e r mina l of t he 20 0 V Inv e rte r with a gr ou nd re sist ance of less than 100 W and t ha t
of the 400 V Inverter with a ground resistance of l ess than 10 W.
•
Do not share the ground wire with other devices, such as welding machines or power tools.
•
Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and
the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
•
When using more than one Inverter, be careful not to loop the ground wire.

Quick program m ing mode
Advanced programming mode Use this mode to reference and set all user parameters.
Verify mode
Autotuning mode*
Use this mode when monitoring values such as frequency references or output current, displaying fault information or displaying the fault history.
Use this mode to reference and set the minimum user parameters to operate the
Inverter (e.g., the operating environment of the Inverter and Digital Operator).
Use this mode to read/set user parameters that have been changed from their factory-set values.
Use this mode when running a motor with unknown motor parameters in the vector
control mode. The motor parameters are calculated and set automatically.
This mode can also be used to measure only the motor line-to-line resistance.

Autotuning Mode
Autotuning automatically tunes and sets the required motorparameters when operating in the open-loo p or
flux vector control modes. Always perform autotuning before starting operation.
When the motor can not be disconnected from the load, perform stationary autotuning. Contact y our dealer to
set motorparameters by calculation.
The Inverter ’s autotunin g function automatically determines the motor parameters, while a servo system’s
autotuning function determines the size of a load, so these autotunig functions are fundamentally different.
Example of Operation
Set the motor output power (in kW) and ra ted c urrent specif ied on the namep late on the m otor a nd then press
the RUN key. The motor is automatically run and the motor line-to-line resistance measured based on these
settings will be set.
Always set the above items. Autotuning cannot be started otherwise.
Parameters can be changed from the setting display s. Use the Increment, Decrement and D igit Selection/
RESET keys to change the frequency. The parameter will be written and the display will be returned to monitor display when the ENTER key is pressed after changing the setting.

Application Settings
Parameters are set as required in advanced programming mode (i.e., with the ADV indicator lit on the Digital
Operator). All the parameters that can be set in quick programming mode can also be displayed and set in
advanced programming mod e .
Setting Examples
The following are examples of settings for applications.
To increase the speed of a 50 Hz motor by 10%, set E1-04 to 55.0 Hz.
•
To use a 0 to 10-V analog signal for a 50 Hz motor for variable-speed operation between 0 and 45 Hz (0%
•
to 90% speed deduction), set H3-02 to 90.0%.
To control speed between 20% and 80% to ensure smooth gear operation and limit the maximum speed of
•
the machine, set d2-01 to 80.0% and set d2-02 to 20.0%.
No-load Operation
This section describes trial operation in which the motor is in no-load state, that means the machine is not connected to the motor. To avoid failures caused du e to the wiring of the contro l circuit it’s recommended to use
the LOCAL mode. Press the LOCAL/REMOTE Key on the Digital Operator to change to LOCAL mode (the
SEQ and REF indicators on the Digital Operator should be OFF).
Always confirm safety around the motor and machine before starting Inverter operation from the Digital
Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter. For applications, at which the machine only can be driven in one direction, check the motor rotation direction.
Jog Frequency Reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and releasing the
JOG Key on the Digital Operator. If the external sequence prevent operation from the Digital Op erator, confirm that emergency stop circuits and machine safety mechanisms are functioning and then start operation in
REMOTE mode (i.e., with a signal from the con trol signal te rminals). T he sa fety p recautions m ust always be
taken before starting the Inverter with the motor connected to the machine.
Both a RUN command (forward or reverse) and a frequency reference (or multi-step spe ed command) must
be provided to start Inverter operation.
Input these commands and reference regardless of the operation me tho d (i.e., LOCA L of REMOTE).

Operation using the Digital Operator
Use the Digital Operator to start operation in LOCAL mode in the same way as in no-load operation.
•
If fault occurs during operation, make sure the STOP Key on the Digital Operator is easily accessible.
•
At first, set the frequency reference to a low speed of one tenth the normal operating speed.
•
Checking Operating Status
Having checked that the operating direction is correct and th at the machine is operating sm oothly at slow
•
speed, increase the frequency reference.
After changing the frequency reference or the rotation direction, check that there is no oscillation or abnor-
•
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not to high.

Check and Recording Parameters
Use verify mode (i.e., when the VERIFY indicator on the Digital Operator is lit) to check parameters that have
been changed for trial operation and record them in a parameter table.
Any parameters that have been changed by autotuning will also be displayed in verify mode.
If required, the copy function in parameters o3-01 and o3-02 displayed in advanced programming mode can
be used to copy the changed settings from the Inverter to a recording area in the Digital Op erator. If changed
settings are saved in the Digital Operator, they can be easily copied back to the Inverter to speed up system
recovery if for any reason the Inverter has to be replaced.
The following functions can also be used to manage parameters.

S-curve characteristics (C2-01 and C2-02) Used to prevent shock when completing acceleration.
Jump frequencies (d3-01 to d3-04) Used to avoid resonance points during acceleration or deceleration.
Stall prevention (L3-01 to L3-0 6)
Adjust torque during acceleration and deceleration.
Used to prevent OV (overvoltage errors) and motor stalling for heavy
loads or rapid acceleration/deceleration. Stall prevention is enabled by
default and the setting normally has not to be changed. When using a
braking resistor, however, disable sta ll pr eve ntion during decel era tion by
setting L3-04 to 0.

Current Detection:
The speed search is started from
the frequency when power was
momentarily lost and the maximum frequency and the speed is
detected at the search curr ent
level.
Sets the speed search op eration
current as a percentage, taki ng
the Inverter rated current as
