■Ambient Temperature Control
·To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature
changes.
·If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to
maintain the internal air temperature below 50 ℃ (Close mounting: below 40 ℃ ).The life of the built-in
electrolytic capacitors of the Inverter is prolonged by maintaining the internal air temperature as low as possible.
·The surface temperature of the Inverter may rise approximately 30 ℃ higher than the ambient temperature. Be
sure to keep away equipment and wires from the Inverter as far as possible if the equipment and wires are easily
influenced by heat.
■Protecting Inverter from Foreign Matter during Installation
·Place a cover over the Inverter during installation to shield it from metal power produced by drilling.
Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will be
affected, causing the Inverter to overheat.

■Wiring on the Input Side of the Main Circuit
● Installing a Molded-case Circuit Breaker
Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via a molded case circuit
breaker (MCCB) suitable to the Inverter.
·Install one MCCB for every Inverter used.
·Choose an appropriate MCCB capacity according to the Circuit breaker capacity column in the table on the
previous page.
·For the MCCB's time characteristics, be sure to consider the Inverter's overload protection (one minute at 150%
of the rated output current)
·If the MCCB is to be used in common among multiple Inverters, or other devices, set up a sequence such that
the power supply will be turned off by a fault output, as shown in the following diagram.

Section 2 Design
● Installing a Ground Fault Interrupter
Inverter outputs use high-speed switching, so high-frequency leakage current is generated.
In general, a leakage current of approximately 100 mA will occur for each Inverter (when the power cable is 1 m)
and approximately 5 mA for each additional meter of power cable.
Therefore, at the power supply input area, use a special-purpose breaker for Inverters, which detects only the
leakage current in the frequency range that is hazardous to humans and excludes high-frequency leakage current.
·For the special-purpose breaker for Inverters, choose a ground fault interrupter with a sensitivity amperage of at
least 10 mA per Inverter.
·When using a general leakage breaker, choose a ground fault interrupter with a sensitivity 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 of the main circuit is to be shut off because of the sequence, a magnetic contactor(MC) can be
used instead of a molded-case circuit breaker(MCCB).
When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly, however, the
regenerative braking does not work and the load coasts to a stop.
·A load can be started and stopped by opening and closing the magnetic contactor on the primary side.Frequently
opening and closing the magnetic contactor, however, may cause the Inverter to break down. In order not to
shorten the service life of the Inverter's internal relays and electrolytic capacitors, it is recommended that the
magnetic contactor is used in this way no more than once every 30 minutes.
·When the Inverter is operated with the Digital Operator, automatic operation cannot be performed after recovery
from a power interruption.
● Connecting Input Power Supply to the Terminal Block
Input power supply can be connected to any terminal on the terminal block because the phase sequence of input
power supply is irrelevant to the phase sequence (R/L1, S/L2, and R/L3).
● Installing an AC Reactor
If the Inverter is connected to a large-capacity power transformer (660 kW or more) or the phase advance capacitor
is switched, an excessive peak current may flow through the input power circuit, causing the converter unit to break
down.
To prevent this, install an optional AC reactor (optional) on the input side of the Inverter.
This also improves the power factor on the power supply side.
● Installing a Surge Absorber
Always use a surge absorber or diode for the inductive loads near the Inverter. These inductive loads include
magnetic contactors, electromagnetic relays, solenoid valves, solenoid, and magnetic brakes.
● Installing a Noise Filter on the Power Supply Side
The Inverter's outputs uses high-speed switching, so noise may be transmitted from the Inverter to the power line
and adversely effect other devices in the vicinity. It is recommended that a Noise Filter be installed at the Power
Supply to minimize noise transmission. Noise will also be reduced from the power line to the Inverter.

Section 2 Design
■Wiring on the Output Side of the Main Circuit
● Connecting the Terminal Block to the Load
Connect output terminals U/T1, V/T2, and W/T3 to motor lead wires U, V, and W.
Check that the motor rotates forward with the forward command. Switch over any two of the output terminals
(U/T1,V/T2,W/T3) to each other and reconnect if the motor rotates in reverse with the forward command.
● Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U/T1, V/T2, or W/T3.
If voltage is applied to the output terminals, the internal circuit of the Inverter will be damaged.
● Never Short or Ground Output Terminals
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. Also, be careful not to short the output wires.
● Do not Use a Phase Advancing Capacitor or Noise Filter
Never connect a phase advance capacitor or LC/RC Noise Filter to the output circuit.
Doing so will result in damage to the Inverter or cause other parts to burn.
● Do not Use an Electromagnetic Switch of Magnetic Contactor
Do not connect an electromagnetic switch of magnetic contactor to the output circuit.
If a load is connected to the Inverter during running, an inrush current will actuate the overcurrent protective circuit
in the Inverter.
● Installing a Thermal Relay
The 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 and set n6.06(moto protection function) to 2 (no thermal protection).
In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is turned off by
the contact of the thermal relay.
● Installing a Noise Filter on the Output Side
Connect a Noise Filter to the output side of the Inverter to reduce radio noise and induction noise.

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

● Cable Length between Inverter and Motor
As the cable length between the Inverter and the motor is increased, the floating capacity between the Inverter
outputs and the ground is increased proportionally. The increase in floating capacity at the Inverter outputs causes
the high-frequency leakage current to increase, and this may adversely affect peripheral devices and the current
detector in the Inverter's output section. To prevent this from occurring, use a cable of no more than 100 meters
between the Inverter and the motor. If the cable must be longer than 100 meters, take measures to reduce the floating
capacity by using AC Reactor on output side,
(choose AC Reactor the same as the one on the input side and set carrier frequency 2K max.)
Also, adjust the carrier frequency according to the cable length between the Inverter and the motor, as shown in the
following table.
Cable length
50m max.
100m max.
More than 100m
Carrier frequency
10kHz max.
5kHz max.
2kHz max.
● Single-phase motors cannot be used
The Inverter is not suited for the variable speed control of single-phase motors.
The rotation direction of a single-phase motor is determined by the capacitor starting method or phase-splitting
starting method to be applied when starting the motor.
In the capacitor starting method, however, the capacitor may be damaged by a sudden electric discharge of the
capacitor caused by the output of the Inverter. On the other hand, the starting coil may burn in the phase-splitting
starting method because the centrifugal switch does not operate.

■地线的配线
·Always use the ground terminal with the following ground resistance:
200-V Inverter: 100 Ω or less
400-V Inverter: separate ground,10 Ω or less
·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, the 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.

■Countermeasures against Harmonics
With the continuing development of electronics, the generation of harmonics from industrial machines has been
causing problems recently.
● Harmonics
·Definition
Harmonics consist of electric power produced from
AC power and alternating at frequencies that are
integral multiples of the frequency of the AC power.
The following frequencies are harmonics of a 60- or
50-Hz commercial power supply.
Second harmonic: 120 (100) Hz
Third harmonic: 180 (150) Hz
·Problems Caused by Harmonics Generation
The waveform of the commercial power supply will
be distorted if the commercial power supply contains
excessive harmonics. Machines with such a
commercial power supply will malfunction or
generate excessive heat.
·If basic frequency reachs kHz, then the high harmonics of it will be the high frequency hamonics.
Second harmonic (120 Hz)
Basic frequency
(60 Hz)
Third harmonic (180 Hz)
Basic frequency
(60 Hz)
Third harmonic (180 Hz)
Distorted current
wave form
● Causes of Harmonics Generation
·Usually, electric machines have built-in circuitry that converts commercial AC power supply into DC power.
Such AC power, however, contains harmonics due to the difference in current flow between DC and AC.
·Obtaining DC from AC Using Rectifiers and
Capacitors
DC voltage is obtained by converting AC voltage into
a pulsating one-side voltage with rectifiers and
smoothing the pulsating one-side voltage with
capacitors. Such AC current, however, contains
harmonics.
Voltage
Time
·Inverter
The Inverter as well as normal electric machines has
an input current containing harmonics because the
Inverter converts AC into DC. The output current of
the Inverter is comparatively high. Therefore, the ratio
of harmonics in the output current of the Inverter is
higher than that of any other electric machine.
A current flows into the capacitors.
The current is different from the
voltage in waveform.

● Countermeasures with Reactors against Harmonics Generation
·AC Reactors
The AC reactor suppress harmonics and currents that change suddenly and greatly.
The input power factor of the Inverter is improved by suppressing the harmonics of the input current of the
Inverter.

5-2 Operation under V/f status
This mode, which is used by conventional general-purpose inverters, is convenient when replacing a conventional
model with 3G3JZ Inverter because the Inverter in this mode can be operated without considering the constants of
the motor.
To operate the Inverter in V/f control mode, be sure to set n7.00 (rated motor current) and n1.00 - n1.06 (V/f
mode).
5-2-1 Setting rated motor current （n7.00）
Check the the motor nameplate and set this parameter to the rated current.
This set value is used for determining the electronic thermal characteristics to protect the motor from overheating.
The correct set value protects the motor from burning that may result from overloading.

·Set the rated motor current on motor nameplate in A increments.
※ 1.The setting range of rated motor current differs according to inverter models. The setting can be made between
30% and 120% of inverter's rated output current approximately.
※ 2.The default setting of rated motor current differs according to inverter models. Set the value to the 75% of
inverter's rated output current approximately.
※ 3.When several motors are connected to one inverter, the electronic thermal characteristics protecting the motor
from overheating will not run normally. Set n6.06 (motor protection selection) = 2 to disable electronic thermal
function, then set thermal protection devices outside every motor.
5-2-2 Setting V/f Patterns （n1.00 ～ n1.06）
Set the V/f pattern so that the motor output torque is adjusted to the required load torque.
SYSDRIVE 3G3JZ incorporates an automatic torque boost function. Therefore, a maximum of 150% torque can be output at
3 Hz without changing the default setting. Check the system in trial operation and leave the default settings as they are if no
torque characteristic changes are required.

·Set the minimum frequency applied on the motor in n1.05 according to the applied minimum speed. The
frequency lower than n1.05 setting value is disabled, the inverter will block the output and the motor will not
rotate.
·The vertical-axis load or the load with high viscous friction may require high torque at low speed. If the torque is
insufficient at low speed, increase the voltage in the low-speed range by 1 V, provided that no overload (OL1 or
OL2) is detected. If an overload is detected, decrease the set values or consider the use of an Inverter model with a
higher capacity.
·Under fan control or pump control, because the necessary torque is in proportion of the second power or third
power of speed, setting the V/f mode with quadratic (cubic) function to lower the voltage in low speed area will
help save energy.

performs signal communication by specifying a number. The slave which receives the command from the host
gives response.

■Register Data Transfer
Register data (such as monitor value or parameter set value) locate in communication blocks of message data
(request message or response message). All data in registers are sent in 2-byte data.
Data is transferred to hex in min. set unit of each register
Eg., if frequency reference is 60 Hz and min. unit is 0.01 Hz, data will be transferred as below:
60Hz/0.01(Hz)=6000=1770Hex
Monitor items
Register 2123H: frequency reference monitor
Register 2124H: frequency output monitor
Communication register
Register 2102H: frequency reference
Negative values are represented as 2S complement code
If frequency curve is -100%, min. unit will be 1%, data will be transferred as below:
100%/1%=100=0064Hex
2S complement code: FF9CHex
Positive or negative, depends on parameter settings.
MSB of negative value is always 1, however, data with MSB=1 is not always a negative value.
No data setting in unused registers
Unused registers may be used in internal treatments, do not write any data to these registers.

■No Response from Slave
In following cases, slaves ignore command information from hosts, and do not send response information.When
executing write function, if slave address specified by command is 0, response information to the host will not be
sent although all slaves are executing write.
·Error detected in command (overshooting, frame, parity or CRC-16);
·Slave address of command is differ from slave address of inverter;
·Time interval between data is longer than 24 bits;
·Length of execution information is incorrect
Precautions
Please set the timer which monitors slave response time
at the host.When the slave does not respond to the slave
in time setting, please set the host to send same
commands in this case.

■Protocol Macro Function
The protocol macro function makes it possible to customize a communications protocol in order to create a macro
according to the specifications of the serial communications port of a general-purpose peripheral device.
The protocol macro function is mainly used for the following jobs.
·Creation of the message communications frame
·Creation of Send & Recv procedures for the message communications frame
TERMS
This manual uses the terms “message, DSR message, and response”to express the
communications data exchanged.
Message: A DSR message or response.
DSR message: A message sent by the Master for commands to the Inverter.
Response: A message that the Inverter returns in compliance with a DSR message from the MasterTERMS Master.
Creating a Message
The message can be created according to the communications specifications of the general-purpose peripheral
device (Inverter) as a counterpart. A DSR message can include variables to set data in the I/O memory (such as data
memory) of the CPU Unit or write response data to the I/O memory. Each component of a message is in the
memory of the Communications Board. Therefore, the CPU Unit can just execute the PMCR command to send or
receive the data, with no need to write ladder programs for the communications protocol.

■Configuration of the Protocol Macro Function
The protocol consists of one or more sequences. A sequence is an independent set of actions to perform together
with a general-purpose peripheral device, such as an Inverter. For example, the RUN command and the frequency
reference are given to the Inverter and the status of the Inverter is read in a single sequence. A sequence consists of
one or more steps. A step consists of a Send & Recv command + a Send & Recv message + a step branch in
accordance with the processing result + Completion.
Sequence
When repeating actions to give the RUN command and frequency reference to the Inverter and read the status of the
Inverter, for example, the actions can be registered as one sequence, or more than one if necessary. In "Creating a
Project File", an example is shown with all actions registered as a single sequence. A sequence may include the
following parameters.
Parameter
Description
Transmission control
Set the method of control, such as flow control.
Select only modem control for communications with the 3G3JZ.
Link word
Set the area for sharing the data between the Programmable Controller and
Communications Board.
In "Creating a Project File", an example is shown without such an area set.
Monitor time
Set the periods to monitor the transmission and reception steps with timers Tr,
Tfr, and Tfs.
Set a period of approximately 0.5 s each for communications with the 3G3JZ.
Response notify method
A method to write reception data to the I/O memory of the Programmable Controller.

Step
In a single step, a DSR message is sent and a response for the DSR message is received. A step may not include a
response if it is a broadcast message. In the case of repetitive actions to issue the RUN command and frequency
reference to the Inverter and read the status of the Inverter, for example, the actions to give the RUN command and
frequency reference constitute one step. The reason is that these register numbers are consecutive and can be sent
with a single DSR message. The action to read the status of the Inverter is another step. A step includes a command
and a maximum of two messages. The above example uses the Send & Recv command. The DSR message and
response are both messages.
A step may include the following parameters.

Send message
A DSR message is set for the Send command used.
Recv message
A response is set for the Recv command.
Send & Recv message
A DSR message and response are set for the Send & Recv command.
Recv matrix
If there are two or more responses for the Send or Send & Recv command, the next
process is selected per response.
Repeat counter
The number (N) of times to repeat the step is set within a range from 0 to 255.
It is possible to change messages by making use of the number (N).
Under Creating a Project File, an example is shown with this function used for
enabling three Slaves to repeat the same process.
Number of retries
The number of times to retry the command can be set within a range from 0 to 9 only
when the Send & Recv command is used.

specified)
Determines whether or not to write the reception data in the response.
Under Creating a Project File, an example is shown with this function used for
writing the Inverter status to the memory.
Next process
Determines which step is to be processed next, or finishes the operation after the
step is finished normally.
Error processing
Determines which step is to be processed next, or finishes the operation, if the the
step has an error.

use of the standard system protocol, copy it to the project file and edit it. Under Creating a Project File, an example
to create a new project file is shown without making use of the standard system protocol.
■Creating a Project File
The following description provides information about how to create a project file to send the RUN command and frequency
references to three Inverters and read the Inverter status. ( “PST”indicates the WS01-PSTF1-J Protocol Support Tool.)
First, select from I/O items, monitor items, and parameters the data to be exchanged according to the application.
Then consider what sequence is required by using the protocol macro function.
Example: Writes control input items (such as the RUN command and multi-function input) of the Inverter and
frequency reference, monitors the control output (such as error output and RUN output) of the Inverter, and monitors
the Inverter status.
Three Inverters with Slave addresses from 01 to 03 are installed for communications.
Checking the Register Numbers
In the above example, the following three registers are required.
Control Input: Register 0001 Hex for RUN command
Frequency Reference: Register 0002 Hex
Control Output: Register 002C Hex for Inverter status

Step
Step number. The step number is automatically set.
Repeat
The number (N) of times to repeat the step is set within a range from 0 to 255. It is possible to change messages by
making use of the number (N).
In this example, the same message is sent to three Slaves with addresses different to each other. Therefore, the
number is set to 3 in word S + 1. The number of Slaves is specified by the operand. Therefore, select Channel, use
the Edit command to set Data Address to Operand, and set 0N + 1 in order to select word S + 1. In the above table,
“Reset”means that the repeat counter must be reset first in the step.
Command
Set the commands, such as Send, Recv, and Send & Recv.
Only the Send & Recv command is used for communications with the 3G3JZ except for broadcasting messages, in
which case the Send command is used.
Retry
Set the number of times to retry the command within a range from 0 to 9.
It is recommended that the number be set to 3 or larger. If a transmission error occurs due to noise, the transmission of
the command will be retried. If the number is set to 3, an error will be detected if the transmission fails three times.
Send Wait
The waiting time until the data is sent.
For communications with the 3G3JZ, if data is repeatedly transmitted to the same Slave, set the waiting time to
20 ms or more.
Send Message and Recv Message
Set the labels of the DSR message and response to be used.
Make these settings after deciding the labels in Send Message Detail Settings and Recv Message Detail Settings.
Response
Determine whether or not to write the reception data in the response.
Always set this parameter to Yes for communications with the 3G3JZ.
Next
Determine which step is to be processed next or finish the operation after the step finishes normally.
In this example, step 00 is set to Next and step 01 is set to END because the sequence completes be executing steps 00 and 01.
Error
If the step has an error, determine which step is to be processed next or finish the operation.
In this example, the parameter will be set to Abort to interrupt the sequence if an error occurs.

7-10 Communications Time
■Communications Response Time
The communications response times for communications with an Inverter via the RS-422/485 port of an OMRONmade Communications Board are detailed below. Use this information as a reference when deciding the number of
Slaves to be connected to one network, and when considering the timing of input and output signals.
Communications Time for One Message
A wide variety of programs for RS-422/485 communications can be created using the protocol macro function. The
communications times will vary according to the contents of the program.
In general, the communications time for one message can be calculated using the following formula.
Communications time = [Number of bytes in DSR message × 10 (See note 1.) × (1/baud rate) × 1,000 (ms)] +
[Number of bytes in response × 10 × (1/baud rate) × 1,000 (ms)] + [24 × (1/baud rate) × 1,000 (ms)] + send
wait time setting (ms) + protocol macro waiting time (See note 2.) (ms)
The reason that the number of bytes in the DSR message and response is multiplied by 10 is because both the start
bit and the stop bit require one bit each.
(1 byte = 8 bits) + (start bit: 1 bit) + (stop bit: 1 bit) = 10 bits
With RS-422A/485 communications, set at least 20 ms as the protocol macro waiting time.
Calculation Example
The communications time required for one Slave in the protocol macro created in Creating a Project File, can be
calculated according to the following formula. (Baud rate = 19,200 bps.)
Communications time = [(DSR message to write data (13 bytes) + DSR message to read (8 bytes)) × 10 × (1/
19,200) × 1,000 (ms)] + [(write response (8 bytes) + read response (7 bytes)) × 10 × (1/19,200) × 1,000 (ms)] +
[24 × (1/19,200) × 1,000 (ms) × 2] + [10 (ms) × 2] + [20 (ms) × 2] = 81.2 (ms)
If there are N Slaves, the total communications time will be N × 81.2 ms. Consequently, the more Slaves that are
used, the longer the communications time will be. If the number of Slaves is too high, it is possible that the detection
time of 2 s for communications time-over will be exceeded. In this case, either disable the time-over detection
function and use a different sequence to detect communications errors, or increase the number of Masters thereby
decreasing the number of Slaves per Master.

8-1-1 Fault Detection
The Inverter will detect the following faults if the Inverter or motor burns or the internal circuitry of the Inverter malfunctions.
When the Inverter detects a fault, the fault code will be displayed on the Digital Operator, the fault contact output
will operate, and the Inverter output will be shut off causing the motor to stop. (The stopping method can be
selected for some faults, and the selected stopping method will be used with these faults.)
If a fault has occurred, refer to the following table to identify and correct the cause of the fault.
Use one of the following methods to reset the fault after restarting the Inverter. If the operation command is being input,
however, the reset signal will be ignored. Therefore, be sure to reset the fault with the operation command turned off.
·Turn on the fault reset signal.
(Turn on the fault reset signal. A multi-function input (n4.05 to n4.08) must be set to 5 (Fault Reset).
Alternatively, set the bit of Fault Reset (bit No. 3 of register No. 2101 Hex) to 1 (ON) by communication.)
·Press the STOP/RESET Key on the Digital Operator.
·Turn the main circuit power supply off and then on again.

Motor Fails to Operate
■ The motor does not operate with input through the control circuit terminals even though the frequency
reference is correct.
·The operation method setting is incorrect.
If parameter n2.01 for operation mode selection is not set to 1 or 2 to enable the control circuit terminals block, the
RUN command cannot be executed through the control circuit terminals.
Check and correct the setting in n2.01.
·Both Forward rotation command and Reverse rotation command are set to ON.
If both Forward/Reverse rotation command are set to ON , the Inverter will not operate.
Check and correct the setting. Do not set Forward rotation command and Reverse rotation command to ON at the same time.
·Input in 2-wire sequence while 3-wire sequence is in effect and vice-versa.
The Inverter will operate in 3-wire sequence according to the RUN, stop, and forward/reverse commands if n4.04
for multi-function input 1/2 is set to 2. At that time, the Inverter will not operate if input in 2-wire sequence is ON.
8-7
Chapter 8 Application
On the other hand, the Inverter in 2-wire sequence will only rotate in the reverse direction if input in 3-wire
sequence is ON.
Check and correct the setting in n04.04 or change the input method of the RUN command.
·The frequency reference is too low.
If the frequency reference is set below the minimum output frequency set in n1.05, the Inverter will not operate.
Raise the frequency reference to at least the minimum output frequency.
·Switching RUN command by using multi-function input
To set “18 (operation command switch: control terminals)”, “19 (operation command switch: operator)”and
“20 (operation command switch: communication)”in multi-function input (n4.05-n4.08) to switch operation
command temporarily. The commands will be performed in the priority order as below:
n2.01 (Selecting operation command) ＜ 20 (operation command switch: communication) ＜ 19 (operation
command switch: operator) ＜ 18(operation command switch: control terminals)
·The input wiring of the control circuit terminals of the Inverter is incorrect.
The Inverter cannot check the input signal if the input line of the control circuit terminals is incorrectly wired.
The default setting for Inverter input is to NPN sequence input, which can be changed to PNP sequence input.
Refer to 2-2-2 Terminal Block and check that the SW1 settings conform with the actual wiring.
■ The motor does not operate with input through the control circuit terminals. (The frequency reference is
zero or different from the set value.)
·The frequency reference setting is incorrect.
The analog input of frequency references is ignored with the Digital Operator selected. The digital input of frequency
references is ignored unless the Digital Operator is selected.
Check that the setting in n2.00 for frequency reference selection coincides with the actual method of giving frequency
commands.
·Switching frequency command by using multi-function input
Set "22 (the secondary frequency command n2.09)", "1-3 (multi-step speed command", "8 (Jog command)" in the
multi-function input (n4.05 to n4.08) to switch the frequency command. The commands will be performed in the
priority order as below:
n2.00 (Selecting frequency command) ＜ 22 (the secondary frequency command n2.09) ＜ 1-3 (multi-step
speed command)
·The analog input(frequency command input A1 terminal) setting is incorrect.
Check that the analog input(frequency command input A1 terminal) setting in n4.11 to 4.18 are set according to
the actual analog input characteristics.
■ The motor stops during acceleration or when a load is connected.
·The load may be too big.
The 3G3JZ has a stall prevention function and automatic torque boost function, but the motor responsiveness limit
may be exceeded if acceleration is too rapid or if the load is too big.
Lengthen the acceleration time or reduce the load. Also consider increasing the motor capacity.
■ The motor only rotates in one direction.
·Reverse rotation-prohibit is selected.
If n2.04 for reverse rotation-prohibit selection is set to 1 (reverse run prohibited) or 2 (forward run prohibited), the
Inverter will only rotates in one direction.
(If the reverse rotation-prohibit is selected, the Inverter will not accept reverse-rotation commands and if the forward
rotation-prohibit is selected, the Inverter will not accept forward-rotation commands).
To use both forward and reverse rotation, set to 0 (Reverse rotation-enable).
8-8
Chapter 8 Application
3
Motor Rotates in the Wrong Direction
·The output wiring of the motor is faulty.
When the U, V, and W terminals of the Inverter are properly connected to the U, V and W terminals of the motor,
the motor operates in a forward direction when a forward rotation command is executed.
The forward direction depends on the maker and the motor type. Therefore, be sure to check the specifications.
Switching two wires among the U, V, and W will reverse the direction of rotation.
·Reverse rotation-prohibit is selected.
If n2.04 for reverse rotation-prohibit selection is set to 1 (reverse run prohibited) or 2 (forward run prohibited), the
Inverter will only rotates in one direction.
Therefore, if the reverse rotation-prohibit is selected, the Inverter will not accept reverse-rotation commands and
if the forward rotation-prohibit is selected, the Inverter will not accept forward-rotation commands.)
To use both forward and reverse rotation, set to 0 (Reverse rotation-enable).
4
Motor Outputs No Torque or Acceleration is Slow
·The stall prevention level during running is too low.
If the value in n6.01 for stall prevention level during acceleration is too slow, the acceleration time will be too long.
Check to be sure that the set value is suitable.
·The stall prevention level during acceleration is too low.
If the value in n6.02 for stall prevention level during operation is too low, the speed will drop before torque output
is turned ON.
Check to be sure that the set value is suitable.
7
If the Vertical-axis Load Drops When Brake Is Applied
·There is a fault in the sequence.
Because of the output status of inverters do not in concordance with the Brake operation, cause the load drops.
Set "21 (External brake output)" in multi-function output (n3.00) to operate the brake.
By setting the parameters n3.11(External brake open frequency) and n3.12 (External brake operation frequency)
to make sure that the frequency will not drop.
·The wrong brake is being used.
Use the main brake rather than the holding brake.
8
Motor Burns
·The load is too big.
If the load of the motor is too big and the motor is used with the effective torque exceeding the rated torque of the
motor, the motor will burn out. For example, the rated torque of the motor and capacity may be limited to eight
hours of use if the inscription on the motor states that the motor is rated for eight hours.
If the 8-hour rated torque is used for normal operation, it may cause the motor to bun out.
Reduce the load amount by either reducing the load or lengthening the acceleration/deceleration time.
Also consider increasing the motor capacity.
·The ambient temperature is too high.
The rating of the motor is determined within a particular ambient operating temperature range. The motor will
burn out if it runs continuously at the rated torque in an environment in which the maximum ambient operating
temperature is exceeded.
Lower the ambient temperature of the motor to within the acceptable ambient operating temperature range.

·The withstand voltage between the phases of the motor is insufficient.
When the motor is connected to the output of the Inverter, a surge will be generated between the switching of the
Inverter and the coil of the motor.
Normally, the maximum surge voltage is approximately three times the input power supply voltage of the Inverter
(i.e., approximately 600 V for 200-V models, and approximately 1,200 V for 400-V models).
Therefore, the dielectric strength of the motor to be used must be higher than the maximum surge voltage.
In particular, use a dedicated motor for 400-V Inverters.
9
Controller or AM Radio Receives Noise when Inverter is Started
■ Noise derives from Inverter switching.Take the following actions to prevent noise.
·Lower the carrier frequency of the Inverter in n2.03.
The number of internal switching times is reduced, so noise can be reduced to some extent.
·Install an Input Noise Filter.
Install an Input Noise Filter on the power input area of the Inverter.
·Install an Output Noise Filter.
Install an Output Noise Filter on the output area of the Inverter.
·Use metal tubing.
Electric waves can be shielded by metal (iron). Therefore, enclose the Inverter with a metal tube.
10
Ground Fault Interrupter is Actuated when Inverter is Started
·Leakage current flows through the Inverter.
The Inverter performs internal switching. Therefore, a leakage current flows through the Inverter. This leakage
current may actuate the ground fault interrupter, shutting the power off.
Use a ground fault interrupter with a high leakage-current detection value (sensitivity amperage of 200 mA or
more, operating time of 0.1 s or more) or one with high-frequency countermeasures for Inverter use.
Reducing the carrier frequency value in n2.03 is also effective.
In addition, remember that a leakage current increases in proportion to the cable length. Normally, approximately
5 mA of leakage current is generated for each meter of cable.
11
Mechanical Vibration
■ Mechanical system makes unusual noise.
·Resonance between the characteristic frequency of the mechanical system and the carrier frequency.
There may be resonance between the characteristic frequency of the mechanical system and the carrier frequency.
If the motor is running with no problems and the machinery system is vibrating with a high-pitched whine, it may
indicate that this is occurring. To prevent this type of resonance, adjust the carrier frequency value in n2.03.
·Resonance between the characteristic frequency of a machine and the output frequency of the Inverter.
There may be resonance between the characteristic frequency of a machine and the output frequency of the Inverter. To prevent
this from occurring, use the frequency jump function with the constants set in n8.09 through n8.12 to change the output
frequency or install vibration-proof rubber on the motor base to prevent the resonance of the me chanical system.
■ Motor vibrates excessively and does not rotate normally.
·Motor Phase Interruption
If one or two of the three phases of the motor are open, the motor will vibrate excessively and will not rotate.
Check that the motor is wired correctly without any disconnection. The same phenomenon will occur if the output
transistor of the Inverter is open and damaged. Check the balance of the Inverter's output voltage as well.

Motor Rotates after Output of Inverter is Turned OFF
·Insufficient DC Injection Braking Control
If the motor continues operating at low speed, without completely stopping, and after a deceleration stop has been
executed, it means that the DC injection braking is not decelerating enough.
In such cases, adjust the DC control as described below.
-Increase the parameter in n8.00 for DC injection braking current.
-Increase the parameter in n8.02 for DC injection braking-to-stop time.
-Increase the parameter in n8.03 for DC injection braking-to-stop initialfrequency, adjust to the appropriate frequency.
14
Detects OV (Over voltage) and Stalls when Motor Starts
·Insufficient DC Injection Braking Control at Startup
Generation of OV and stalling can occur if the motor is turning when it is started.
This can be prevented by slowing the rotation of the motor by DC injection braking before starting the motor.
Increase the parameter in n8.01 for startup DC injection braking time.
15
Output Frequency Does Not Reach Frequency Reference
·The frequency reference is within the jump frequency range.
If the jump function is used, the output frequency stays within the jump frequency range.
Make sure that the jump width settings in n8.09 through n8.12 for jump frequencies 1 through 2 are appropriate.
·Exceeds the upper-limit frequency.
The upper-limit frequency can be obtained from the following formula.
Maximum frequency in n1.00 × frequency reference upper limit in n1.07/100.
Make sure that the parameters in n1.00 and n1.07 are correct.
16
Motor Rotates Momentarily When Control Device Power is Turned OFF
·Malfunction Due to Unwanted Current Path
Inverter inputs may remain ON due to an unwanted current path for the controller outputs.
With the wiring shown in the following table, if the controller output power supply is less than 24 V DC or if the
power is OFF, the current indicated by the arrow will flow and the Inverter inputs will operate.
If that occurs, insert a diode as shown in the diagram at point A.

Set the operation level under which deceleration
time function automatically stops in order to
prevent overvoltage (OV) during deceleration. Set
with the voltage value of DC power supply of the
main circuit. Generally it is not required to change
the set value.
※ When stall prevention during deceleration is
enabled, overvoltage is detected, set the
parameter to a lower value.
If the parameter is set too low, the inverter can
not deceleration, causing the stop duration very
long, which should be attended to.
