Installation Environment
Make sure the ambient temperature remains within the rated range ( −10 to 50°C). Take note that if the ambient temperature reaches or exceeds 40 °C, the carrier frequency and output current must be derated. If the Inverter is used in an environment exceeding the allowable operating temperature range, the product life of the Inverter (specifically, the capacitor) will be shortened.
Measure and check the temperature approx. 5 cm from the bottom center of the Inverter body.
Provide sufficient space around the Inverter because it can become very hot (up to 150 °C or so).
Keep the Inverter away from heating elements (such as a Braking Resistor, reactor, etc.).
Although side-by-side installation is possible. The ambient temperature of the installation site must not exceed 40 °C and the carrier frequency and output current must be derated if side-byside installation is used.
100 mm or more

2-1 Installation
In particular, make sure that the installation site is free from condensation.If condensed water adheres to the Inverter's internal parts, the electronic components may short-circuit, causing failure of the Inverter.In addition to avoiding condensation, avoid installing the Inverter under direct sunlight.
Avoid an environment where the Inverter may be exposed to dust, gases (corrosive, explosive, and/or flammable), grinding fluid mist, or salt.If a foreign object (e.g. dust) enters the Inverter, it could result in failure of the Inverter.If using the Inverter in a dusty place, take appropriate measures. (For example, place the Inverter in a closed panel.)
When several Inverters are installed in a panel and a ventilation fan is mounted in the panel, be careful about the layout of the Inverters and the air intake apertures.Depending on the layout, the Inverter's cooling effect may deteriorate, resulting in an increase in the ambient temperature.

2-2 Wiring
Wiring the Main Circuit Terminals
Before wiring, make sure that the CHARGE indicator is OFF.
Once the power supply is turned on, the capacitor in the Inverter is charged with high voltage for a while even after the power supply is turned off and regardless of whether the Inverter is running or not.
If you are going to change cable connections after the power supply is turned off, wait for at least
10 minutes. Before wiring, check for a residual voltage between terminals "P/+2" and "N/ −" with a circuit tester to ensure safety.
Main power supply input terminals (R/L1, S/L2, T/L3)
Use an earth leakage breaker for circuit (wiring) protection between the power supply and the main power supply terminals (R/L1, S/L2, T/L3).
An earth leakage breaker may malfunction at high frequency. Use an earth leakage breaker with a large high-frequency sensitive current rating.
As a guide for leakage current, if a CV wire is used and routed through a metal pipe, the leakage current is 30 mA/km. Due to the higher specific inductive capacity of the H-IV wire, the leakage current increases about eight times.Use a wire with a sensitivity current one-level higher. The leakage current mentioned here is the effective value of the fundamental wave, and high-frequency currents are excluded.

When the Inverter protective function is activated, your system may fail or an accident may occur. Connect a magnetic contactor to turn off the Inverter power supply.
Do not start or stop the Inverter by switching ON/OFF the magnetic contactor provided in the
Inverter power supply input (primary) circuit and output (secondary) circuit.To start or stop the
Inverter via an external signal, use the operation command terminals (FW, RV) on the control circuit terminal block.
Do not use this Inverter with an input phase loss connection. Doing so may damage the
Inverter.
The Inverter operates with 1-phase input during input phase loss, causing a trip (due to undervoltage, overcurrent, etc.) or damage to the Inverter. Even if an input phase is open, the internal capacitor is charged with voltage, and electric shock or injury may occur.
When changing the cable connections, refer to "Precautions for Use."
SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)
2-10

2-2 Wiring
In the following cases, the internal converter module may be damaged:
Imbalance ratio of power supply voltage is 3% or more.
Power supply capacity is ten times or more than the Inverter capacity, and 500 kVA or more.
Rapid change in power supply voltage
Example) When several inverters are connected with a short bus.
When the phase advance capacitor is turned on/off.
Do not turn on the power and then turn it off again more than once every 3 minutes. Doing so may damage the Inverter.
Inverter output terminal (U/T1, V/T2, W/T3)
For connection of the output terminal, use the compatible cable or a cable with a larger diameter. Otherwise, the output voltage between the Inverter and the motor may drop.
Particularly during low-frequency output, a voltage drop occurs with the cable, resulting in motor torque reduction.
Do not mount a phase advance capacitor or surge absorber, because these devices may cause the Inverter to trip or cause damage to the capacitor or surge absorber.
If the cable length exceeds 20 m (particularly, with 400 V class), a surge voltage may be generated at the motor terminal depending on stray capacitance or inductance of the cable, causing the motor to burn out.
To suppress surge voltage, we offer a special filter (3G3AX-NFxxx). For details, contact our authorized dealer.
To connect several motors, provide a thermal relay for each.
The RC value of each thermal relay should be 1.1 times larger than the motor rated current.The
relay may trip earlier depending on the cable length.In this case, connect an AC reactor to the
Inverter output.
DC Reactor Connection Terminal (+1, P/+2)
This terminal is used to connect the optional DC reactor.
By factory default, a shorting bar has been connected between terminals +1 and P/+2. Before connecting the DC reactor, remove this shorting bar.
The length of the DC reactor connection cable should be 5 m or shorter.
If the DC reactor is not being used, do not remove the shorting bar.
If you remove the shorting bar without connecting the DC reactor, no power is supplied to the
Inverter main circuit, disabling operation.

External Braking Resistor Connection Terminal (P/+2, RB)/Regenerative Braking Unit Connection Terminal (P/+2, N/

All models in the 3G3MX2 Series have a built-in regenerative braking circuit.
To improve braking capacity, mount the optional braking resistor to this terminal.
Do not mount a resistor whose resistance is lower than the specified value.Doing so may damage the regenerative braking circuit.
The cable length should be 5 m or shorter. Twist the two wires.
Do not connect any device other than the optional Regenerative Braking Unit or Braking
Resistor to this terminal.
Ground Terminal
To prevent electric shock, be sure to ground the Inverter and the motor.
The 200 V class should be connected to the ground terminal under Class D grounding conditions (conventional Class 3 grounding conditions: 100
Ω or less ground resistance), The
400 V class should be connected to the ground terminal under Class C grounding conditions
(conventional special Class 3 grounding conditions: 10
Ω or less ground resistance).
For the ground cable, use the compatible cable or a cable with a larger diameter. Make the cable length as short as possible.
When several Inverters are connected, the ground cable must not be connected across several
Inverters, and must not be looped. Otherwise, the Inverter and surrounding control machines may malfunction.

Note 1: Applicable devices assume use of a standard 3-phase, 4-pole motor.
Note 2: Select an applicable circuit breaker by also considering the cutoff capacity. (Use an inverter type.)
Use one circuit breaker for one inverter according to the applications shown in the above table.
Note 3: If the wiring distance exceeds 20 m, the power cable size must be increased.
Note 4: A H-IV wire (75
°C) is recommended.
Note 5: Use an earth leakage breaker (ELB) to ensure safety.
Note 6: To meet the UL standards, always insert a UL-standard fuse of class J type on the power supply side.
Note 7: Use a ground wire with a larger diameter than that of the power cable shown above.
Note 8: Tighten the terminal-block screws with the specified torque. If the screws are not tightened securely, short-circuiting or fire may occur. Excessive tightening may cause damage to the terminal block or the Inverter.
Note 9: Choose the sensitivity current of the earth leakage breaker (ELB) depending on the total distance between the Inverter and the power supply, and the Inverter and the motor. Also, use an earth leakage breaker of time-delay type. Use of a high-speed type may result in malfunction.
Note 10: If a CV wire is used and routed through a metal pipe, the leakage current becomes 30 mA/km.
Note 11: Due to the higher specific inductive capacity of the IV wire, the leakage current increases about eight times. Accordingly, use a wire with a sensitivity current of eight times the applicable level shown in the table below. Also, use a CV wire if the total wiring length exceeds 100 m.

Wiring Control Circuit Terminals
Wiring and Arranging a Control Circuit Terminal Block
Terminals SC and PC are common terminals for input/output signals. They are isolated each other. Do not short-circuit or ground these common terminals.
Do not ground these common terminals via external equipment and check the external equipment ground conditions.
Connect diodes when wiring input/output signals for multiple inverters, because sneak circuit paths are created.
For wiring of each control circuit terminal, use a twisted-pair shielded cable and connect the shielded cable to each common terminal.
The control circuit terminal connection cable should be 20 m or shorter. Separate the control circuit terminal connection cables from the main circuit cable (power cable) and the relay control circuit cable. If the two cables must be crossed with each other, make sure they bisect at right angles. Otherwise, the Inverters may malfunction.
For connection of the thermistor input terminal, connect the twisted wires to terminal SC individually, and separate them from other SC common cables. Since a weak current flows through the thermistor, the thermistor connection cable must be separated from the main circuit cable (power cable).The thermistor connection cable should be 20 m or shorter.
When providing contacts for control circuit terminals (multi-function input terminals, etc.), use a relay that will not cause contact failure even when the current or voltage is weak, such as a relay with cross-bar twin contacts.
To use a relay for a multi-function output terminal, connect a surge-absorbing diode in parallel with the coil.
Do not short-circuit the analog power supply terminals (FS-SC) and/or the interface power supply terminals (P24 and SC). Doing so could result in failure of the Inverter.
The control circuit terminal block has two rows of terminals at top and bottom. Since wiring the top terminals first makes it difficult to wire the bottom terminals, wire the bottom terminals first.
After the wiring, gently pull the wires to confirm that they are securely connected.

Procedure for Test Run
Command/Reference Input From the Digital Operator
1. Check if the wires are connected correctly.
2. Turn on the power of the Inverter.
3. Set Frequency Reference Selection (A001) to "02" (Digital Operator).
4. Set RUN Command Selection (A002) to "02" (Digital Operator).
5. Set Output Frequency Setting (F001). It is recommended to set a low speed of approx.
10 Hz first to ensure safety.
6. Set RUN Direction Selection (F004).
7. Display Output Frequency Monitor (d001) and press the Enter key.
Confirm that "0.00" (Hz) is displayed.
8. Press the RUN key. The RUN (during RUN) LED indicator is lit and the motor starts to turn.
9. Confirm the output frequency and motor rotation direction displayed on the Digital
Operator, and check if the Invertor is free from errors. For the motor rotation direction, refer to Rotation Direction Monitor (d003).
10. If no problem is found, gradually increase the output frequency using Output
Frequency Setting (F001).
11. After checking the operation, press the STOP/RESET key. The motor starts to decelerate and once it stops, the RUN (during RUN) LED indicator turns OFF.
Command/Reference Input From the Control Circuit Terminal Block
1. Check if the wires are connected correctly.
2. Turn on the power to the Inverter.
3. Set Frequency Reference Selection (A001) to "01" (Control circuit terminal block).
4. Set RUN Command Selection (A002) to "01" (Control circuit terminal block).
SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)

3-3 Test Run
5. Display Output Frequency Monitor (d001) and press the Enter key.
Confirm that "0.00" (Hz) is displayed.
6. After confirming that the analog voltage/current value for frequency reference is 0, turn the RUN command ON. The RUN (during RUN) LED indicator is lit.
7. Gradually increase the analog voltage/current value for frequency reference.
* The frequency reference can be set first, before setting the RUN command in 6.
The motor accelerates/decelerates according to the acceleration/deceleration time set in F002/F003.
8. The motor starts to turn. Confirm the output frequency and motor rotation direction displayed on the Digital Operator, and check if the Inverter is free from errors.
9. After checking the operation, turn the RUN command OFF (turn the STP input ON in the case of 3-wire input). The motor starts to decelerate and once it stops, the
RUN (during RUN) LED indicator turns OFF.
Check for tripping during acceleration/deceleration, and also check if the rotation speed and frequency readings are correct.
If an overcurrent or overvoltage tripping occurs during trial operation, try to increase the acceleration/deceleration time.
Confirm by Output Current Monitor (d002) and DC Voltage Monitor (d102) to confirm that the current/voltage values are sufficiently away from the tripping values.

SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)
3-4 Tripping
3-4 Tripping
Upon detecting an error (overcurrent, overload, etc.) during operation, the Inverter cuts off the output to the motor to protect the motor and Inverter. At the same time, the ALARM LED indicator is lit and an error code is displayed. "Tripping" refers to this series of operations.
When a tripping occurs, the motor goes into free-run status. Identify the cause of the error from the displayed error code, and remove the cause.
A RUN command is not accepted during a tripping. To reset a tripping, press the STOP/RESET key. If a Reset (18: RS) is allocated to the multi-function input terminal, switching the reset input from ON to OFF resets a tripping.
Note, however, that a tripping may not be reset depending on the cause of the tripping. In such case, reconnect the power.
Also, confirm the RUN command and various other input signals thoroughly before executing a reset. If the RUN command signal remains ON, the Inverter will restart immediately after the reset.

If Frequency Reference Selection is set to Digital Operator (A001 = 02), enabling d001/d007
Frequency Setting Mode Selection (b163 = 01) lets you change the Output Frequency Monitor
(d001) setting using the Increment/Decrement keys only during operation.
Changed Output Frequency Monitor (d001) will be reflected to the Output Frequency Setting
(F001). Pressing the Enter key stores the setting in the EEPROM.
Since F001 is rewritten while d001 is still displayed, there may be a time gap between the key operation and display change depending on the acceleration/deceleration time.
While the PID function is activated or being stopped, the output frequency cannot be changed.
The frequency cannot be changed in the individual input mode by pressing the Increment/
Decrement keys simultaneously.

Heavy Load/Light Load Selection
The rated specification of the Inverter is selected from the two types: heavy load rating and light load rating.
The rated current is different between the heavy load rating and light load rating, and the electronic thermal characteristics, overload warning level and other items also vary accordingly. Select either type according to the load actually used.
When the setting of Heavy Load/Light Load Selection is changed, the parameters shown in the table below are reset to their default values and at the same time the heavy load/light load rating changes. There is no need to reconnect the power or perform initialization.
The high-frequency mode is supported only when the heavy load rating is selected. For the

Frequency Reference Selection and Output Frequency Setting
Select the method of the frequency reference.
Since multi-step speed operation (in which a combination pattern of input terminals is used to specify the speed) is given priority over Frequency Reference Selection (A001), A001 need not be set. Only when all multi-step speed inputs are OFF and therefore 0th is specified, the frequency conforms to the setting of A001.

Base Frequency
Adjust the base frequency to the motor specification.
If you apply a base frequency of over 60 Hz, a special motor is required. This may require the
Inverter to increase its capacity to accommodate a different applicable motor.
Set the motor incoming voltage selection according to the motor specifications.
This function is disabled if the control method is Free V/f Setting (A044/A244 = 02). (Refer to
"Free V/f Setting" on page 5-47.)

AVR Function
This function outputs voltage to the motor correctly even if the incoming voltage to the Inverter fluctuates.
The output voltage to the motor is based on the voltage selected by motor incoming voltage selection. Note, however, that a voltage exceeding the incoming voltage cannot be output.
AVR Filter Time Parameter/Voltage Gain During Deceleration
During deceleration, the motor functions as a generator and the generated energy is returned to the Inverter. As a result, the Inverter's DC voltage rises and if it exceeds the overvoltage level, an overvoltage (OV) trip occurs. Setting a higher output voltage increases the motor loss and energy consumptions, and consequently shortens the deceleration time. (However, the motor load increases.)
To shorten the deceleration time without causing an overvoltage trip, select OFF for AVR selection during deceleration for or tune the voltage characteristics using the AVR filter time parameter and voltage gain during deceleration.

*1.The deceleration time can be shortened by increasing the motor loss during deceleration and thereby reducing the regenerated energy returned to the Inverter. If the location of AC incoming voltage is away from the location of motor incoming voltage, however, an overcurrent trip may occur during deceleration. In this case, make adjustment by, for example, selecting "Always ON" for AVR Selection.

Frequency Limit
Both the upper and lower limits can be set for the output frequency. If a frequency reference beyond the upper/lower limits is input, the frequency is limited by the upper or lower limit.
Set the upper limiter first. Make sure the upper limit (A061/A261) is higher than the lower limit
(A062/A262).
Make sure the upper and lower limit settings do not exceed the Maximum Frequency (A004/A204).
Make sure the Output Frequency (F001) and Multi-step Speed References 1 to 15 (A021 to A035) are not lower than the lower limit and not higher than the upper limit.
Neither limit would work if is set to upper and lower limits.

Acceleration/Deceleration Stop Function
This function temporarily stops acceleration/deceleration to perform constant speed operation at the applicable frequency.
This function can be used to make the Inverter wait until the motor slip decreases during acceleration/deceleration, when the moment of inertia of the loaded machine is large. Also use this function if an overcurrent/overvoltage trip occurs during acceleration/deceleration.
This function is not affected by the setting of Acceleration Pattern Selection (A097). It is available in all acceleration patterns.
The following two methods can be used for a stop during acceleration/deceleration, and the two methods can be combined:
(1) Automatic stopping at a desired frequency/stopping time
(2) Stopping with a multi-function input terminal
Take note that the acceleration/declaration time set in F001/F202 or F003/F203 will not be enabled.

Output Voltage Gain
The voltage output by the Inverter can be changed based on the voltage selected by Motor
Incoming Voltage Selection (A082/A282) which is handled as 100%.
Motor hunting can be avoided by lowering the gain.
If the control method is Sensorless Vector Control (A044/A244 = 03), the setting change is effective only while operation is stopped. After the setting has been changed, be sure to turn
Reset (RS terminal) to ON and then OFF. The motor parameter is recalculated after the reset.
Do not change the setting significantly during operation. (As a guide, keep the change to within
10%). A sudden change in output voltage may trigger an overcurrent trip.

PID Deviation Reverse Output
Depending on the sensor characteristics, etc. the polarity of deviation between the target value feedback values may not match the Inverter's command. In this case, the deviation polarity can be reversed by using the PID Deviation Reverse Output (A077 = 01).
Example) Controlling a refrigerator compressor
The temperature sensor specification is 0 to 100 °C: 0 to 10 (V) and the target value is 5 °C.
If the current temperature is 10 °C, "(Feedback value) > (Target value)" is satisfied and therefore the Inverter frequency drops under normal PID control.
→ Set A077 to "01" so that the Inverter increases the frequency.

PID Variable Range Limit
This function limits PID output within a variable range relative to the target value.
To use this function, set PID Variable Range Limit (A078). The output frequency is limited within a range of "target value

PID Gain Adjustment
If a stable response cannot be obtained in PID function operation, adjust each gain as follows according to the situation.
The feedback value changes slowly when the target value is changed. → Raise P Gain A072.
The PID feedback value changes fast but isn't stable.
The PID feedback value fluctuates unstably.
→ Lower P Gain A072.
The target and the PID feedback values wouldn't match smoothly. → Lower I Gain A073.

→ Raise I Gain A073.
→ Raise D Gain A074.
With P gain raised, the PID feedback value fluctuates and isn't stable. → Lower D Gain A074.
PID Excessive Deviation (OD)
You can set PID excessive deviation level C044 during PID control. A signal can be output to a multi-function output terminal when the PID deviation
ε reaches the level set in C044 or above.
Allocate "04: OD" to any Multi-function Output Terminal Selections (C021 to C022) or Relay

PID Sleep Function
When the PID output drops to below the setting of PID Sleep Function Operation Level (A156), output will stop after the period set in PID Sleep Operation Delay Time (A157). The stop method (deceleration stop/free run) conforms to Stop Selection (b091). The PID sleep function does not actuate if recovery occurs within the PID sleep operation delay time.
Even when the PID function is disabled, output will still stop after the period of A157 when the frequency reference value drops to below the setting of A156. The stop method conforms to the setting of b091.

Automatic Energy-saving Operation Function
This function automatically adjusts the Inverter output power during constant speed operation in order to minimize it. This function is suitable for load with reduced torque characteristics (e.g. fan, pump).
When operation is performed using this function, set RUN Mode Selection (A085) to "01: Energysaving operation."
Response and accuracy can be adjusted using Energy-saving Response/Accuracy Adjustment (A086).
Control is performed at a relatively slow rate, so if a sudden load fluctuation like an impact load, etc.
occurs, the motor may stall, resulting in an overcurrent trip.
When the frequency reference uses the terminal block (analog input), the automatic energy-saving function may not function sufficiently. In this case, set Analog Input Filter (A016) to "31: 500 ms."

Stabilization Parameter
This function is used for adjustment to reduce motor hunting.
In case of motor hunting, check whether motor capacity H003/H203 and motor pole number selection H004/H204 match your motor. If they do not, match them. If the motor's primary resistance is smaller than that of the standard motor, increase the H006/H206 set value gradually. To run a motor with a capacity larger than the Inverter's rated capacity, reduce the set value.
Other than this function, the following methods are suggested to reduce hunting:
Lower the Carrier Frequency (b083).

until restart, after output is shut off.
Function
Advantages
Disadvantages
Frequency matching restart
This method restarts the Inverter by detecting frequency based on the motor's residual voltage.
The Inverter can be restarted smoothly.
The Inverter cannot be restarted if the residual voltage is at a certain level or below (in which case the Inverter restarts at 0 Hz).
Frequency pull-in restart
The Inverter starts output at the frequency set in Starting Frequency (b030), and searches for a point where the frequency and voltage are balanced, while holding the current at the setting of Restart Current Level (b028), to restart itself.
If the Inverter trips with this method, reduce the b028 set value.
The Inverter can be restarted regardless of whether or not there is residual voltage.
Shock may occur upon restart.
(The current may surge. If an overcurrent trip occurs, also use Overcurrent Suppression
Function b027.)

Restart Upon Momentary Power Interruption/Undervoltage, Overvoltage/Overcurrent
Whether to trip or restart the Inverter upon momentary power interruption/undervoltage or overvoltage/overcurrent can be selected.
Restart upon Momentary Power Interruption/Undervoltage, Overvoltage/Overcurrent
When a restart function is selected under Retry Selection (b001), the Inverter restarts repeatedly for the number of times set in b005 in the case of momentary power interruption/ undervoltage, or in b010 in the case of overvoltage/overcurrent, and then trips at the next restart. The Inverter does not trip when unlimited restart is set. Unlimited restart can be set only for Momentary Power Interruption/Undervoltage Restart (b005).
b004 can be used to select whether the Inverter trips or not when a momentary power interruption or undervoltage occurs while stopped.
When selecting a restart function, set the following restart conditions according to the system.
A desired function can be selected from 0 Hz restart, frequency matching restart, frequency matching deceleration trip, and frequency pull-in restart.
Even when the Inverter is restarting, an E09 (undervoltage) trip occurs if an undervoltage condition continues for 40 seconds.

*3.0 Hz restart may occur in the following cases:
• The output frequency is one-half the base frequency or below
• The induced voltage of the motor attenuates quickly
*4.If an overvoltage/overcurrent trip occurs during declaration, Undervoltage Error E09 is displayed and the motor goes into free-run status. In this case, increase the deceleration time.
*5.Even when a restart operation upon trip is selected, the Inverter continues to trip if the cause of the trip is not yet removed after Restart Standby Time (b003) elapses. In this case, increase the restart standby time.

Reset (RS)
This function resets an Inverter trip.
To reset an Inverter trip, press the STOP/RESET key on the Digital Operator, or turn ON the reset (RS) terminal.
When using the reset terminal, allocate "18: RS" to a multi-function input terminal.
The restart method to be applied after the reset operation can be selected by Reset Restart
Selection (C103). Take note, however, that the Inverter will restart at 0 Hz if Reset Selection
(C102) is set to "03: Trip reset only," regardless of the setting of C103. If an overcurrent trip occurs at frequency matching, extend the Restart Standby Time (b003).
A trip reset time can be selected by Reset Selection (C102). In addition, the reset signal can be applied only to trip reset due to an error.
For the Reset (RS) terminal, only the NO contact setting is effective.
Do not use the reset terminal to stop the Inverter output. The reset operation will clear various data such as electronic thermal function and usage rate counter for regenerative braking, thereby causing damage to the Inverter.

Free-run Stop Function (FRS)
Activating the free-run stop (FRS) function shuts off the Inverter output, letting the motor go into free-run status.
This function is effective when you stop the motor using the mechanical brake such as an electromagnetic. Note that an overcurrent trip may occur if the mechanical brake forces the motor to stop during Inverter output.
Allocate "11: FRS" to any Multi-function Input Selections (C001 to C007). The moter performs a free-run stop while the FRS terminal is turned ON.
When the FRS terminal is turned ON and then OFF, the Inverter will restart after an elapse of the time set in Restart Standby Time (b003). However, the Inverter will not restart if RUN
Command Selection is set to "Digital Operator" (A002 = 02). To restart the Inverter, input the
RUN command.
As the Inverter output method at restart, 0 Hz restart, frequency matching restart or frequency pull-in restart can be selected by Free-run Stop Selection (b088). (Examples 1, 2, 3)
When Frequency Matching Lower Limit Frequency Setting (b007) is set, the Inverter will restart at 0 Hz if a frequency below the frequency set here is detected at the time of frequency matching restart.
The setting of this function will be applied to the FRS terminal, and also when the Inverter is reset from free-run status.

*1.When b050 = 02 or 03, PI control is performed to keep the internal DC voltage constant. Though quicker response is expected when the setting of Proportional Gain (b133) is increased, if the setting is too large a trip will occur easily. With a smaller proportional gain setting on the other hand, an undervoltage trip will occur due to a drop in voltage immediately after this function starts operating. Response also becomes quicker when the setting of Integral Time (b134) is decreased, but if the setting is too small a trip will occur easily, as well.
*2.Make sure that the set values of b051 and b052 are larger than the undervoltage level (210 V for 200

If the difference between the settings of (b051) and (b052) is large, and setting too large a value for proportional Gain (b133) may cause sudden acceleration immediately after this function starts operating and overcurrent may flow.

(The Inverter will accept neither a STOP command nor frequency reference change until the operation is completed.)Make sure that the b052 setting is higher than the normal incoming voltage or equivalent.
*4.If the Freq. Drop to Start Ctrl. Decel (b054) is too large, an overcurrent trip occurs because of rapid deceleration. If b054 is too small, or if the Deceleration Time of Ctrl. Decel (b053) is too long, an undervoltage trip occurs because of insufficient regeneration power.

The control power supply is momentarily interrupted, or the main circuit DC voltage falls below the setting of DC Bus Voltage Trigger Level of Ctrl. Decel b051.
If the time of momentary power interruption is short, the Inverter can continue to run without shutting off the output. However, if undervoltage occurs because of momentary power interruption, the Inverter immediately shuts off the output, and stops operating this function.
The subsequent power recovery depends on the Retry Selection b001.
With b050 = 03, the Inverter can be restored to normal operation, if a momentary power interruption occurs and incoming voltage recovers before the output is shut off. Note that the

Electronic Thermal Characteristics
Although only one type of electronic thermal characteristic curve is available each for heavy load and light load, the frequency characteristics can be switched by Electronic Thermal Characteristics Selection (b013/b213).
A standard motor requires reduced load (current) because the lower the motor rotation speed is, the lower the cooling capacity of its self-cooling fan gets. When the frequency drops, the reduction multiple also decreases and the thermal level (current) drops, as well.
The reduced torque characteristics depend on the heat radiation of a standard motor.

5-9 Functions Relating to Protections, Warnings and Various Output Signals
Overload Limit/Overload Warning
Overload Limit
The Inverter monitors the motor current during acceleration or constant speed operation and lowers output frequency automatically when the motor current reaches to the overload limit level.
This function prevents an overcurrent trip caused by excessive moment of inertia during acceleration, or caused by sporadic load fluctuations during constant speed operation.
You can set 2 types of overload limit functions in b021/b022/b023 and b024/b025/b026.
To switch between b021/b022/b023 and b024/b025/b026, allocate "39: OLR" to a multifunction input terminal and then turn it ON/OFF.
The overload limit level sets a current value for this function to work.
The overload limit parameter sets a time of deceleration from the maximum frequency to 0 Hz.
When this function operates while the Inverter is accelerating, the acceleration time becomes longer than the set time.
When the selected control method is sensorless vector control and "03: Enabled during acceleration/constant speed (accelerated during regeneration)" is selected for b021/b024, the frequency will increase if current exceeding the overload limit level flows during regeneration operation.
If the setting of Overload Limit Parameter b023/b026 is too small, an overvoltage trip may occur because of regenerative energy from the motor even during acceleration. This is due to automatic deceleration under this function.
Make the following adjustments if this function operates during acceleration and the frequency doesn't reach the target level.
Increase the acceleration time (refer to "Acceleration/Deceleration Time" on page 5-24).
Increase the overload limit level (b022/b025).

Overvoltage Suppression Function During Deceleration
This function helps avoid an overvoltage trip due to regenerative energy from the motor during deceleration.
Whether to enable or disable this function can be selected by Overvoltage Suppression
Function Selection During Deceleration (b130). If "01: Enabled (DC voltage kept constant)" is selected, the Inverter decelerates automatically in order to keep the voltage rise in the main circuit DC unit at the start of deceleration, to the value of Overvoltage Suppression Level
During Deceleration (b131).
If "02: Enabled (Acceleration enabled)" is selected, the Inverter will accelerate according to the setting of Overvoltage Suppression Parameter (b132) when the voltage of the main circuit
DC unit rises at the start of deceleration and exceeds the value of Overvoltage Suppression
Level During Deceleration (b131). After that, when the main circuit DC voltage falls below the b131 level, the Inverter starts deceleration again.

*1.When b130 = 01, PI control works to keep the internal DC voltage constant.
Though quicker response is expected when the setting of Proportional Gain (b133) is increased, control tends to be divergent and this may easily lead to a trip. Response also becomes quicker when the setting of Integral Time (b134) is decreased, but if the setting is too small the same situation may occur.

With this function enabled, the actual deceleration time may be longer than the set value.
Particularly with b130 = 02, if b131 is set too low, the Inverter may not decelerate.
Even if this function is enabled, an overvoltage trip may occur depending on the deceleration rate and load condition.
When using this function, the Inverter may reduce frequency depending on the moment of inertia of motor load, and takes a long time to stop.
If the value set in b131 is lower than the incoming voltage or equivalent, the motor may not be stopped.
When (b130 = 01), PI control works to keep the internal DC voltage constant.
Though quicker response is expected when the setting of Proportional Gain (b133) is increased, if the setting is too large a trip will occur easily.Response also becomes quicker when the setting of Integral Time (b134) is decreased, but if the setting is too small, a trip will occur easily, as well.

Alarm Signal (AL)
Upon detecting an overcurrent, overvoltage or other error, the Inverter stops the output and outputs an alarm signal (AL). This is called a "trip."
When the Inverter is reset, the trip status is reset and the alarm signal also turns OFF. A trip can be reset by pressing the STOP/RESET key or turning the reset terminal ON and then OFF.
(Some trips may not be reset using the reset terminal depending on their cause. In this case, the power must be reconnected. )
Allocate "05: AL (Alarm output)" to any Multi-function Output Terminal Selections (C021 to
C022) or Multi-function Relay Output Function Selection (C026). (This function is allocated to the relay in default setting.)
The relay is based on SPDT contact. For details, refer to "Multi-function Output Terminal

Thermistor Trip Function
This function enables thermal protection of the external equipment (e.g. motor) if its internal thermistor is connected to the Inverter.
Wire the external thermistor between control terminals S5/TH and SC and allocate TH to Multifunction Input Terminal S5 (C005 = 19: TH).
Set the following functions according to the specifications of your thermistor.
When this function is used, keep the cable length between the motor and Inverter within 20 m.
Since the current flowing through the thermistor is weak, consider separating the wires, etc. to prevent noise due to motor current.

DC Injection Braking (DB)
DC injection braking can be applied to the motor depending on the load.
DC injection braking is performed in one of two methods: external DC injection braking using a multi-function input terminal, and internal DC injection braking performed automatically when starting/stopping. Even if DC injection braking is used, however, the motor may not stop depending on the moment of inertia of the motor load.

Internal DC Injection Braking (A051 = 01)
DC injection braking can be applied without terminal operation at start/stop of the Inverter.
To use internal DC injection braking, set Internal DC Injection Braking Selection (A051) to "01:
Enabled."
Set the Startup DC Injection Braking Power using A057, and set the startup DC Injection
Braking Time using A058 regardless of the edge or level operation. (Examples 1-a, 1-b)
Set DC Injection Braking Power (A054) to define the braking power other than at startup.
Use Internal DC Injection Braking Frequency (A052) to set the frequency at which to start DC injection braking.
Once DC Injection Braking Delay Time (A053) is set, the Inverter stops output when the frequency reaches the A052 value after the RUN command (FW) has been turned off. During the set time in A053, the motor remains in free-run status. After an elapse of the period set in
A053, DC injection braking starts.
Edge and Level operations for internal DC injection braking work differently when the RUN command switches from STOP to RUN.
Edge operation: Giving priority to DC Injection Braking Time (A055), performs DC injection braking for the set time in A055.
DC injection braking operates for the set time in A055 when the output frequency reaches the set value in A052 after the RUN command (FW) is turned OFF.
Even when the RUN command is turned ON, DC injection braking continues to be applied during the period set in A055. (Examples 2-a, 3-a)
Level operation: Giving priority to the RUN command, shifts to normal operation, ignoring the
DC Injection Braking Time (A055).
When the RUN command is turned ON during DC injection braking, the period set in A055 is ignored and the Inverter returns to normal operation.

Internal DC Injection Braking (Operation Only Based on Set Frequency) (A051 = 02)
DC injection braking can be applied when the output frequency becomes lower than the setting of Internal DC Injection Braking Frequency (A052).
Neither external nor internal DC injection braking is available while this function is selected.
Operates only when the RUN command is turned on.
DC injection braking starts when both frequency reference and current frequency become lower than A052. (Example 1-a)
When the reference frequency becomes 2 Hz higher than the A052 set value, DC injection braking is released and the output returns to normal. (Example 1-a)
If the reference frequency is zero when the operation starts with analog input, operation is started with DC injection breaking because both the reference and current frequencies are zero.(Example 1-b)
If the RUN command is turned on with the determined frequency reference (a value larger than the A052 setting is input), operation is started with normal output.

Regenerative Braking Function
During deceleration, the motor functions as a generator and the generated energy is returned to the Inverter. As a result, the Inverter's DC voltage rises and if the overvoltage level is exceeded, an overvoltage (OV) trip occurs.
This function is intended to prevent this problem by allowing the regenerative energy to be consumed using an external Resistor. It is effective if you want to quickly decelerate the motor or when the load inertia is large.
All 3G3MX2 models have a built-in regenerative braking circuit, so install only a Braking
Resistor externally to the Inverter. To use the Regenerative Braking Unit, set Regenerative
Braking Selection (b095) to "00: Disabled."b090 and b096 will be ignored.

Brake Control Function
This function allows the Inverter to control the external brake of an elevating system.
When Brake Control Function Selection (b120) is set to "01: Enabled," the Inverter operates as follows.
(1) At RUN command input, the Inverter starts output, and accelerates to the release frequency.
(2) After the reaching to the release frequency, the Inverter outputs the brake release signal
(BRK) after the Brake Release Wait Time (b121) elapses. However, if the Inverter's output current is less than the current value set in Brake Release Current (b126), the Inverter does not output the brake release signal. In this case, the Inverter trips, and outputs the brake error signal (BER).
(3) When Brake Confirmation (44: BOK) is set for a multi-function input terminal and a brake release signal is output, the Inverter waits for a brake confirmation signal, without accelerating, for the period set in Brake Wait Time for Confirmation (b124). If the brake confirmation signal does not turn on within the period set in b124, the Inverter outputs the brake error signal (BER), resulting in trip. If the brake confirmation signal is not allocated to a multi-function input, brake confirmation wait time b124 is disabled, and the Inverter performs processing (4) after the brake release signal is output.
(4) After the brake confirmation signal is input (or after the brake release signal is output if BOK is not selected), the Inverter restarts acceleration up to the set frequency after the period set in Acceleration wait time (b122) elapses.
(5) After the RUN command is turned OFF, the Inverter decelerates to the Break ON
Frequency (b127), and turns off the brake release signal (BRK).
(6) When Brake Confirmation (44: BOK) is set for a multi-function input terminal and the brake release signal is turned OFF, the Inverter waits for the brake confirmation signal to turn OFF, without decelerating, for the period set in Wait Time for Confirmation (b124). If the brake confirmation signal is not turned off within the period set in b124, the Inverter outputs the brake error signal (BER), resulting in trip. If the brake confirmation signal is not allocated to a multi-function input, Brake Wait Time for Confirmation (b124) is disabled, and the Inverter performs processing (7) after the brake release signal is turned OFF.
(7) After the brake confirmation signal is turned OFF (or after the brake release signal is turned
OFF if BOK is not selected), the Inverter restarts deceleration down to 0 Hz after the period set in Stop Wait Time (b123) elapses.

5-11 Sensorless Vector Control
The following explains the sensorless vector control, which is based on estimation of the motor rpm and output torque from the motor parameter settings.
Sensorless vector control cannot be selected for High-frequency Induction Motor (b171 = 02) and Light Load Mode (b049 = 01).
Sensorless Vector Control
In this method, the motor rpm and output torque are controlled by estimating these parameters based on the Inverter's output voltage and current, as well as the motor parameter settings.
High starting torque can be generated to enable high-accuracy operation, even in a lowfrequency range (0.5 Hz).
When this function is used, set Control Method (A044/A244) to "03: Sensorless vector control."
When this function is used, make sure to refer to "Motor Parameter Selection" on page 5-145
and that the settings are optimum for the motor used.

Motor Parameter Selection
When sensorless vector control is performed, set the motor parameters according to the motor used.
If multiple motors are used with one Inverter using constant torque characteristics (VC), reduced torque characteristics (VP 1.7th power) or free V/F setting, calculate the total motor capacity and select the closest data in Motor capacity.
When automatic torque boost is used, improper setting of this parameter may result in torque reduction or motor hunting.
The motor parameters can be set by one of the following three methods:
(1) Use the motor parameters of a standard motor
⇒ When the "Standard Motor Parameters" are selected (H002/H202 = 00), the motor parameter values set in H020/220 to H024/224 are applied. The parameters of a standard motor are set in H020/220 to H024/224 by default.
(2) Measure automatically via offline auto-tuning
⇒ When the auto-tuning parameters are selected in Motor Parameter (H002/H202 = 02) after offline auto-tuning, the motor parameters automatically measured by offline auto-
tuning (H030/230 to H034/234) are applied. Refer to "Offline Auto-Tuning Function" on page 5-146.
(3) Set desired parameters
⇒ In either (1) or (2) above, the motor parameters can be changed to desired values.
Change the values of H020/220 to H024/224 or H030/230 to H034/234 according to the value of H002/202. (The parameters of a standard motor are set in H030/230 to H034/

*1.These parameters are used to set motor parameters when auto-tuning is not used. The parameters of a standard motor are set by default.
*2.These parameters are measured automatically when offline auto-tuning is performed. They can also be changed to desired value manually after tuning.
*3.Set an appropriate value according to the motor cable length used.
Note 1: For moment of inertia J, set a conversion value for the motor. After setting the J value, adjust the response speed in Speed Response (H005/H205). The larger the Speed Response (H005/H205), the higher the response speed , resulting in a steep torque rise; the smaller the J value, the lower the response speed, resulting in gradual torque rise.
Note 2: In sensorless vector control, an output in the direction opposite to the RUN command direction may be issued in the control in the low-speed range, etc.
If the motor's reverse rotation may cause a problem, such as damage to the machine driven by
the motor, set Reverse Rotation Prevention Selection (b046) to "01: Enabled". (Refer to "Reverse
Rotation Prevention Function" on page 5-156.)
Note 3: Motor Cable Length Code Selection (b033) is a parameter for compensating the current detection accuracy based on the difference in the motor cable length. This parameter need not be set for 11 kW and 15 kW models.

Description
The motor parameters required in sensorless vector control are automatically measured in a dedicated operation pattern different from that of normal operation, to increase the accuracy of vector control.
The motor parameters are measured without rotating the motor. Use this setting if motor rotation must be prevented. Since the motor does not rotate, motor parameter Io (no-load current) and motor parameter
J (moment of inertia) cannot be measured. The previously set values are held for motor parameter Io and motor parameter J.
The motor parameters are measured by actually rotating the motor.
Use this setting if motor rotation does not cause problems.

5-11 Sensorless Vector Control
When vector control is performed using a motor whose motor parameters are unknown, perform offline auto-tuning to measure the motor parameters.
The motor parameters correspond to data on one phase of Y-connection at 50 Hz.
Adjust the settings of Base Frequency (A003/A203) and Motor Incoming Voltage Selection (A082/
A282) to the specifications of the motor to be measured. If the applicable motor voltage is not available among the options for Motor Incoming Voltage Selection, set the output voltage gain so that "Motor Incoming Voltage (A082/A282)
× Output Voltage Gain (A045/A245) = Rated Motor
Voltage" is established.
The motor parameters can be determined for motors with the maximum applicable capacity or subsequent lower capacity. For motors with other capacities, the Inverter may not correctly determine the motor parameters. (In some cases, auto-tuning may not be completed. In this case, pressing the STOP/RESET key displays an abort message.)
Set Internal DC Injection Braking Selection (A051) and Simple Position Control Selection (P012) to "00: Disabled." If they are set to "01: Enabled," measurement is not performed correctly.
Turn OFF the Torque reference input permission (52: ATR). If it is ON, measurement is not performed correctly.
When performing auto-tuning while the motor is rotating, take note of the following items:
1) There will be no problem even if the motor accelerates up to near 80% of the base frequency.
2) The motor is not driven by external equipment.
3) The brake is released.
4) The torque is not sufficient during auto-tuning. In the case of a lift, etc. the system may "slip and fall." Accordingly, remove the motor from the loaded machine and perform auto-tuning for the motor alone.
(Here, moment of inertia J applies to the motor alone. Accordingly, add the motor-shaft converted value of the moment of inertia of the loaded machine.)
5) In the case of a machine whose motor shaft rotations are limited (lift, ball screw, etc.), the motor may rotate exceeding the allowable rotation and the machine may be damaged as a result.
Accordingly, select "01: Enabled (Motor does not rotate)" in H001.
6) No-load current Io can also be checked by the current monitor function as the current during noload, 50-Hz operation at V/f setting.
Also, the setting obtained by auto-tuning (with the motor rotating) can be rewritten (H023/H223) to the monitored value. It canbe rewritten to the monitored value after executing auto-tuning
(with the motor rotating).
Even when H001 = 01 (Motor does not rotate), the motor may still rotate slightly.
To perform auto-tuning for a motor with the subsequent lower capacity, enable Overload Limit
Selection (b021/b221b024) and set Overload Limit Level (b022/b222) to 1.5 times larger than the rated current of the motor.
If the value of Overvoltage Suppression Integral Time (b134) is small, an Overvoltage Trip (E07) may occur at an auto-tuning.
In this case, increase b134 and then perform auto-tuning again.

Note: To use a motor with a capacity lower than that of the Inverter, set Torque Limit (b041 to b044) by making sure the value α, calculated with the following formula, does not exceed 200%. Otherwise, the motor may burn out.
α = Torque limit value × (Inverter capacity) / (Motor capacity)
Example) From the above formula, the torque limit value to achieve α = 200% with a 0.75 kW Inverter and
0.4 kW motor is calculated as follows:
Torque Limit (b041 to b044) =
α × (Motor capacity) / (Inverter capacity)
= 200%
× (0.4 kW) / (0.75 kW) = 106%.
Torque Monitor Function
This function monitors the estimate output torque of the motor.
This function is enabled only when Sensorless Vector Control is selected for control method
(A044/A244 = 03). Take note that if constant torque characteristics (VC), reduced torque characteristics (VP 1.7th power) or free V/f setting is selected for Control Method (A044/A244), this function is disabled and the output signals for display or through the control terminal block become indeterminable.
To perform monitoring via the Digital Operator, select Display Parameter d012.
To perform monitoring using signals from the control terminal block, refer to "MP Terminal
(Pulse/PWM Output)" on page 5-42 or "AM Terminal (Analog Output)" on page 5-44.
The torque monitor value under this function assumes that the torque corresponding to the
Inverter's rated current is 100%.
Accordingly, the absolute value of torque varies depending on the motor to be combined.

Torque Limit Function
This function limits the motor output torque. This function is enabled only when Sensorless
Vector Control is selected for control method (A044/A244 = 03).
You can select any of the following 3 torque limit functions from Torque Limit Selection (b040).
Four-quadrant separate setting mode
In this mode, torque limits are set separately for the four quadrants of forward power running, forward regeneration, reverse power running and reverse regeneration, using Torque Limits 1 to 4 (b041 to b044).
Terminal switching mode
In this mode, the values set in Torque Limits 1 to 4 (b041 to b044) are switched based on the combination of torque limit switching terminals 1 and 2 (TRQ1,TRQ2) which are set using multi-function input terminals.
Selected torque limit values are enabled for all operation modes.
Analog input mode
In this mode, the torque limits are set based on the voltage applied to the FV terminal (analog voltage) on the control terminal block.
0 to 10 V correspond to torque limit values of 0% to 200%. Selected torque limit values are enabled for all operation modes.
If the Torque limit enabled function (40: TL) is set to a multi-function input terminal, the torque limit function set in b040 is enabled only when TL is turned ON. When TL is off, the torque limit setting is disabled, and the maximum value is defined as the torque limit value. If the Torque limit enabled function (40: TL) is not set to a multi-function input terminal, the torque limit function set in Torque Limit Selection (b040) is always enabled.
The torque limit value under this function assumes that the torque corresponding to the
Inverter's rated current is 100%. Accordingly, the absolute value of torque varies depending on the motor to be combined.
When the Torque limit (10: TRQ) is selected in the multi-function output selection, the torque limit signal turns on when the above torque limit function is activated.

Torque Control
This function is enabled only when Sensorless Vector Control is selected for control method (A044/A244 = 03).
To operate in the torque control, allocate "52: ATR" to any multi-function input terminal. While the ATR terminal is turned on, the torque reference input is enabled.
The torque reference source canbe seledted from two analog types, Digital Operator, etc.
using P033. When analog setting is used, the full-scale value is 200%. (When voltage is used,
10 V corresponds to 200%.)
The torque control speed depends on the balance between torque and load. To prevent the
Inverter from running out of control, set a speed limit value in P039 (forward) or P040 (reverse).
Increasing the speed/torque control switching time reduces the switching shock. The torque reference value under this function assumes that the torque corresponding to the Inverter's rated current is

5-12 Simple Position Control Function
5
Simple Position Control Mode
When Pulse Train Input Terminal RP Selection (P003) is set to "01: Feedback pulse," the pulse train signals are used as feedback information from the encoder. (Enabled for Control 1 only)
The position reference is specified by the combination of multi-function input terminals. Up to eight position references can be specified.
The speed at the time of position reference conforms to Frequency Reference Selection
(A001).
For data with many digits, such as position references, only the higher four digits are displayed.
A terminal command (FW or RV) is required separately as well as position command. (Set
A002 to 01. This is needed to make DC injection braking effective at the time of stopping.During Digital Operator operation, DC injection braking does not function.) For DC
injection braking (DB), refer to"Brake Settings" on page 5-135. (DC injection braking (DB)
settings are required.However, A051 should be set to 00. DC injection braking still functions in this condition if simple position control is active.) Take note that FW/RV does not serve as a rotation direction command while simple position control is active. Both FW and RV function as operation start signals.
The rotation direction is determined by the relationship of the position command and position feedback.

*1.To use the EB terminal (P004 = 01 to 03), allocate "85: EB" to multi-function input terminal S7/EB. When the EB terminal is OFF, the direction is forward. When it is ON, the direction is reverse.
*2. When the dual-phase pulses are used, the maximum input pulse frequency becomes 32 kHz for phase A and 1.8 kHz for phase B. Accordingly, the 3G3MX2 cannot acquire the direction at above 1.8 kHz. In this case, the direction acquisition method can be selected from the following two types. (At restart, etc.)

In simple position control, DC injection braking (DB) is applied after moving to the target position according to the following:
(1) Position command
(2) Speed reference (frequency reference)
(3) Acceleration time, deceleration time
DC injection braking must be set. (DC injection braking (DB) will remain effective until the RUN command is turned OFF.)
In absolute position control, the frequency reference and acceleration/deceleration reference conform to the currently selected parameters.
The exact target position may not be achieved depending on the DC injection braking force or creep speed setting.
If the position command is set to a low value, the Inverter may conduct deceleration and perform positioning before the speed command value is reached. If the position command is
"0," DC injection braking (DB) is applied immediately when the RUN command is turned ON.
The position at power-on is recognized as the zero (position = 0). (When the power is turned off, the current value is cleared.)
SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)
5-12 Simple Position Control Function
If the current position counter exceeds the specified position range, a Position Control Range
Trip (E83) occurs and the Inverter runs freely. If the PCLR terminal is allocated, turning ON the
PCLR terminal clears the current position counter. (The internal position deviation counter is cleared simultaneously.)
In Reset Selection (C102), select "03: Trip reset only."
If Reset Selection (C102) is not set to 03, turning ON the Inverter's reset terminal (STOP/RESET key) clears the current position counter. To operate the Inverter by using the current position count value after resetting a trip by turning ON the reset terminal (STOP/RESET key), be sure to set Reset Selection (C102) to 03.
Reference
In the simple position control mode, the direction of RUN command (FW, RV) does not indicate the rotation direction. The FW or RV signal starts or stops the Inverter. The Inverter runs forward when
"Target position - Current position" is a positive value, or runs in reverse when it is a negative value.
In the simple position control mode, the ATR terminal is disabled.(Torque control is disabled.)
Multi-step Position Switching Function (CP1/CP2/CP3)
Selection of multi-step positions 0 to 7 becomes possible when "66: CP1" to "68: CP3" are allocated to Multi-function Input Selections (C001 to C007).
Set position commands in Multi-step Position Commands 0 to 7 (P060 to P067).
If no position command is allocated to the terminals, Multi-step Position Command 0 (P060) is defined as the position command.

To prevent an erroneous input due to a time lag between inputs in the multi-step position command input mode, the wait time until the terminal input is confirmed can be set using Multistep Speed/ Position Determination Time (C169). This prevents the transition status before input establishment from being applied.
After an input change is detected, data will be confirmed upon an elapse of the time set in
C169. Note that the longer the determination time, the slower the input response.

Speed/Position Switching Function (SPD)
To perform speed control operation in the simple position control mode, turn ON this terminal.
While the SPD terminal is turned ON, the current position counter remains at zero. When the
SPD terminal is turned OFF during operation, position control operation is started the moment the terminal is turned OFF (speed/position switching). At this time, if the position command is
"0" the Inverter immediately stops. (Hunting may occur depending on the DC injection braking force.)
While the SPD terminal is turned ON, the Inverter runs in the direction specified by the RUN command. Accordingly, set the P004 to "02:90
° Dual-phase pulse train 2" when using this function.

5-13 Safety Function
5-13 Safety Function
[Certification pending under the applicable standards]
Overview of Safety Function
The safety function is designed so that the safety stop function of category 0 (uncontrolled stop) specified in IEC 60204-1 is used to meet the safety standard of Stop PLd under ISO
13849-1.
The safety input function allows inverter output when current is flowing to both the GS1 and
GS2 terminals. When the safety input function actuates, the Inverter's output transistor operation is stopped while ensuring the level of safety conforming to the above standard, and the electric power to the motor stops (the motor executes a free-run stop).
It takes less than 10 ms after the safety input is received until the output is stopped.
An Emergency Shutoff (E37) message is displayed and a trip occurs. In the case of a competitive
External Trip (E12) setting, the Emergency Shutoff (E37) setting is given priority unless at poweron.
Note. If the EDM function is not used, PLc under ISO13849-1 applies.
5
Safety Function Setting
Turn ON the safety function selector switch while the Inverter power is turned OFF. The GS1 input and GS2 input are allocated to multi-function input terminals S3/GS1 and S4/GS2 automatically.
If the EDM output (safety monitor output) is used, turn ON the EDM function selector switch.
The EDM output is allocated to multi-function output terminal P11/EDM automatically.

Take note that when the safety function selector switch or EDM function selector switch is turned
ON and then OFF, the input/output terminals previously allocated to the GS1/GS2 inputs and
EDM output are reset to "no," meaning no allocation and the I/O contact selection remains NC contact.
SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)
5-13 Safety Function
How to Wire for/Use Safety Function
Observe the above safety standard and follow the wiring example. Be sure to use both the GS1 input and GS2 input to design a system where both GS1 input and GS2 input are turned OFF upon actuation of the safety function.
Upon detecting an OFF state of the GS1 input or GS2 input, the Inverter actuates the safety function and stops the output.
Reference
The safety monitor (62: EDM) turns ON when the output is cut off upon detection of an OFF state of both the GS1 input and GS2 input signals. If the output stopped due to the safety function but the EDM output did not turn ON, check the GS1 and GS2 input circuits and EDM detection circuit.

When the emergency stop button is pressed, the current flowing through GS1 and GS2 is cut off and the Inverter output is cut off. As a result, the motor enters a free-run status. This operation corresponds to stop category 0 under IEC60204-1.
Note 1. Shown above are wirings that apply when the multi-function input terminals are used based on the source logic. If they are used based on the sink logic, the wiring must be changed. For details,
refer to "Connection to Programmable Controller (PLC)" on page 2-22.
Note 2. The safety relay and emergency shutoff input signal line must use a shielded coaxial cable such as RG174/U (by LAPP) per MIL-C17 or KX3B per NF C 93-550 with an outer diameter of 2.8 mm and length of 2 m or less. Ground the shield.
Note 3. All inductor parts such as relays and contactors must have an overvoltage protection circuit.

Periodic Inspection
If the current stops flowing to either the GS1 or GS2 terminal while the safety function is operating, the Inverter cuts off output. Accordingly, absence of defect in GS1 and GS2 wirings must be inspected periodically. Be sure to conduct a periodic inspection once a year.

Precautions
To make sure the safety function operates normally, evaluate the overall safety system against all risk factors.
The safety function does not mean the input is cut off or output is electrically insulated. Before installation or maintenance work, turn off the Inverter input power supply.
The wires used for the safety function must be 30 m or shorter.
If common GS1 and GS2 are used for two or more Inverters, be sure to install a diode according
to "Note on Use of Multiple Inverters" on page 2-24. GS1 and GS2 may turn ON, thus causing the
Inverter to produce output even in the safety mode.

Inverter Mode Selection
Changing the setting of Inverter Mode Selection alone does not change the mode. After changing this setting, perform an initialization/Mode Selection Command (b180). When the
Inverter mode is changed, the fault monitor data is cleared and the parameters are initialized.
The current Inverter mode can be monitored using d060.
Although the maximum output frequency of the 3G3MX2 is 400 Hz, switching to the highfrequency mode permits output of up to 1,000 Hz. Since the high-frequency mode is supported only in the heavy load rating setting, set the high-frequency mode after selecting Heavy Load
Rating (b049 = 00). (The rating type cannot be changed to light load when the high-frequency mode is selected.)
To perform initialization or clear the fault monitor data while in the high-frequency mode, set appropriate values in b084 and b094 and then perform initialization via b180 according to the normal initialization procedure. It is not necessary to set a value in b171.
Sensorless vector control operation cannot be performed in the high-frequency mode.

Wait time
(Silent interval + C078)
Communication error timeout time (C077)
(1) Frame to be sent from the external control device to the Inverter (Query)
(2) Frame to be returned from the Inverter to the external control device (Response)
(3) Unless the Inverter completes reception of a query from the host within the time set in C077 after the Inverter completes a response (response transmission), the Inverter becomes ready to receive the first data again. In this case, the Inverter sends no response. Also, the
Inverter's operation conforms to the setting of Operation Selection on Communication
Error (C076). For details, refer to Chapter 4. "Parameter List".
The receiving timeout monitor will be started after the first transmission/reception is performed after power-on or reset. Timeout will not occur until reception or transmission is performed.
Response from the Inverter (Frame (2)) will be output as return after the Inverter receives the query (Frame (1)), not output independently.
The silent interval corresponds to 3.5 characters.
Below is each frame format (command).

Error Check
CRC (Cyclic Redundancy Check) is used for the Modbus communication (Modbus-RTU) error check.
The CRC code is a 16-bit data generated against the block of random length data in the 8-bit unit. Generation of CRC codes uses the generation polynomial "CRC-16 (X
16
+ X

+ X

Total Communication Time
The time from receiving query to the response by the Inverter will be the total of <the silent interval (3.5-character length) and C078 (communication wait time) setting>.
If sending another query to the Inverter after receiving the response, be sure to provide the silent interval length (3.5 characters) at the minimum.
Normal Response
If the Parameter No. in the query indicates a loop-back (08h), writing to a coil(s) (05h/0Fh) or writing to a holding register(s) (06h/10h), the Inverter returns a response whose content is the same as the query.
If the Parameter No. in the query indicates reading from a coil (01h) or reading from a holding register (03h), a response is returned whose slave address and Parameter No. are the same as the query and to which data has been added.
Refer to the format for each query specified below.

No Response
The Inverter ignores the query and does not respond if:
Has received a broadcast command (query of address 0).
A communication error is detected in receiving a query.
The query slave address is different from the slave address set for the Inverter.
The time interval between 2 pieces of data that configure the message is less than a 3.5character length.
Query data length is inappropriate.
The reception interval in a frame exceeds the 1.5-character length.
The error check code in the query does not match (CRC error).
Has received a broadcast command for each group (query of address 250 to 254).
If the timer is set in the master to monitor response, but no response is returned within the set time, send the same query again.

Writing Into the Holding Register [06h]
Writes data into the specified holding register.
Example) Write "50.00 Hz" into Output Frequency Setting (F001 = A020) of the Inverter whose slave address is "1".
Since the holding register for output frequency setting has a data resolution of 0.01 Hz, the data to be written should be "5000 (1388h)" when setting 50.00 Hz.

*1. There is no response for broadcasting.
*2. Although the Frequency Reference (F001) normally uses two registers (0001h and 0002h), 50.00 Hz
(5000) is covered by the range of the LSB register, therefore, the data is written to only one register in the above sample. When setting a frequency exceeding 655.35 Hz, write it into two registers simultaneously using a multiple holding register write command (10h).
*3. Note that the holding register start address in F001 (LOW) is "0001h", which is smaller by 1 than the register number "0002h". The register number less 1 corresponds to the register address.
Note that if any parameter other than F001 is rewritten while the data is displayed, the displayed data does not change in real time. Return to the parameter display and show the data gain, and the value reflecting the change will be displayed.

6-6 To Save the Change to the Holding
Register (Enter Command)
If a holding register write command (06h) or consecutive holding register write command (10h) is used, the new register value will become effective but it will not be stored in the Inverter's
EEPROM memory. Accordingly, once the Inverter power is cut off the status will return to the one effective before the holding register was changed.
To store the change to the holding register in the Inverter's EEPROM memory, issue an Enter command according to the method specified below. When the control parameters are changed, the motor parameters must be re-calculated.In this case, also perform recalculation with the Enter command.
6
Issuing Method for the Enter Command
Use a Holding Register Write command (06h) to write into the holding register for Enter command (0900h). At this time, the value to be written into the holding register (0900h) is as follows.

Note 1. The Inverter returns a response to the host when it receives an Enter command, and then executes
EEPROM memory write. You can check whether the data is being written by monitoring the data writing signal (coil number 0049h).
Note 2. Since the Inverter's EEPROM memory has a limit for the number of rewrites (approx. 100,000 times), the Inverter life may be shortened if Enter commands are frequently used.

EEPROM Write Mode
If the holding register write command (06h), etc. is used to write "1" into the holding register for
EEPROM write mode (0902h), the EEPROM, the EEPROM write mode will become active.
If data is changed using the holding register write command (06h) after switching to the EEPROM write mode, the new data is written into both the volatile memory for operation (RAM) and nonvolatile memory for storage (EEPROM). At the same time, the EEPROM write mode is cancelled.
If any command other than the holding register write command (06h) is received after switching to the EEPROM write mode, the EEPROM write mode is cancelled.

6-7 Co-Inverter Communication
6-7 Co-Inverter Communication
The 3G3MX2 provides the Co-inverter communication function to allow for communication among multiple 3G3MX2 Inverters without using a PC, PLC or other master equipment, in addition to performing normal Modbus communication (Modbus-RTU) (slave).
In Co-inverter communication, each Inverter plays the role of "Management Inverter", "Master
Inverter" or "Slave Inverter". For the Management Inverter, the Master Inverter as set by the user is specified. All other Inverters become slave Inverters. Although the Management Inverter is always fixed, the Master Inverter changes sequentially. Accordingly, the Management Inverter may be the Master Inverter or Slave Inverter. Other conditions are specified below:
One Management Inverter is required within the network.
Up to eight Inverters can be selected that function as the Master Inverter.
Up to 247 Inverters (or 32 Inverters without repeater, regulated by the RS-485 network) can be connected across the network.
Station No. 1 operates as the Management Inverter in Co-inverter communication. Accordingly, be sure to provide a Management Inverter of Station No. 1.
The Master Inverter can write data into holding registers in a given Slave Inverter. Up to five different station numbers and holding registers can be specified at a time. When one data transmission is completed between the master and slave, the Master Inverter changes sequentially and data transmission is repeated according to the details set for each Master
Inverter.

*2. A command to switch the Master Inverter from 01 to 02 is sent after an elapse of the silent interval +
Communication Wait Time (C078), following the data transmission from the Inverter 01 master to the slave.
*3. Upon receiving the data sent from the Master Inverter, the Management Inverter sends the next master switching command after an elapse of the silent interval + Communication Wait Time (C078).

*4. Be sure to set the communication timeout for the Management Inverter so that this setting is enabled
(C077 = 0.01 to 99.99). When this setting is disabled (C077 = 0), Co-inverter communication will stop if the data sent from the Master Inverter cannot be received. In this case, reconnect the Management

*3. Set 01 (C072 = 01) as the station number of the Management Inverter.
*4. If the Communication Error Selection of the Management Inverter is set to other than "Ignore" (C076
= 02), Co-inverter communication will stop once the management Inverter experiences a communication timeout. In this case, reconnect or perform a reset (by turning the RS terminal ON and then turning if OFF).
*5. If input terminal start is selected for the Co-inverter Communication Start Selection (C100 = 00), allocate 81 to one of multi-function inputs S1 to S7/EB (485: Start Co-inverter Communication).
*6. If constant communication is selected for the Co-inverter Communication Start Selection (C100 = 01), the Management Inverter starts sending data the moment the power is input. If starting of the Inverter to switch the master to is delayed and thus receiving of the master switching command fails, the
Master Inverter cannot send data and consequently the Management Inverter experiences a receive timeout.
If C100 = 01 is selected, confirm starting of all other Inverters and then start the Management Inverter.
*7. Although the station number of the recipient slave is set in master-slave communication, actually this communication is performed as broadcast communication (station number: 00). Accordingly, data is sent to all stations. The data received by a slave not specified as the recipient by the master will be discarded.
*8. If multiple Master Inverters are provided, set consecutive station numbers for the Inverters.
Communication cannot be performed if the numbers are discontinuous.
*9. Make sure that C098 is equal to or smaller than C099.
6
Co-inverter Communication Setting
Set (C072) a station number for each of the Inverters performing Co-inverter communication by avoiding duplicate numbers. Be sure to set station number 01. The Inverter of station number 01 becomes the "Management Inverter".
For the Management Inverter, set Communication Selection (C096) to "02: Co-inverter communication (management)". For all other Inverters, set Communication Selection (C096) "01:
Co-inverter communication".
Set the station number for Master Inverter in the Management Inverter (C098, C099).
Set the Inverter communication starting method in the Management Inverter (C100). If "00: 485 terminal" is selected for Co-inverter Communication Start Selection (C100), allocate "81: 485
(Start Co-inverter communication)" to one of multi-function Inputs 1 to 7.
Set in the Master Inverter the number of send data items, recipient station number, recipient register and sender register for which the Master Inverter writes into.
Inverter-Inverter Communication Operation
(1) The Master Inverter sends data to each slave inverter according to the items set in the
Master Inverter.
(2) The Management Inverter sends a master switching command and the Master Inverter changes.
(3) The next Master Inverter sends data to each slave inverter in the same manner as in (1).
(4) (2) and (3) are repeated.
Note: Since the Inverter communication is performed in the form of broadcasting (station number: 00), all communication data are sent to all stations. Accordingly, while a slave not specified as the recipient of the Master also receives data, if the data is not addressed to that slave the data will be discarded in the slave.

All slaves receive data from the master, but they will discard the data if the data is not addressed to themselves.
t1: Silent interval + Communication Wait Time (C078) t2: Silent interval + Communication Wait Time (C078) t3: Communication Timeout Time (C077)
For the Management Inverter, be sure to set a value other than 0 (1 s or more is recommended) in Communication Error Timeout Time (C077). When 0 is set, the Co-inverter communication function will stop if the data sent from the Master Inverter cannot be received.If the function has stopped, reconnect the Management Inverter or perform a reset (by turning the RS terminal ON and then turning it OFF).
The communication timeout timer starts counting when the recipient starts waiting for data. If data reception is not completed within the set time, a timeout occurs (t3 in the above figure) and the operation specified by Operation Selection on Communication Error (C076) takes place.
If the Management Inverter is the master, the master switching command is sent after an elapse of the silent interval + Communication Wait Time (C078) following the sending of data by the
Master Inverter (t1 in the figure above).
If an Inverter other than the Management Inverter is the master, the master switching command is sent after an elapse of the silent interval + Communication Wait Time (C078) following the receiving of data from the Master Inverter (t2 in the figure above).
If "01: Always started" is selected for Co-inverter Communication Start Selection, the Management
Inverter starts sending the moment the power is turned on. Accordingly, any delay in the poweron timing of other Inverter prevents normal communication and the Management Inverter experiences a communication timeout. If "Always started" is selected, confirm starting of all other
Inverters and then start the Management Inverter at the end.
Do not set 08FFh (EEPROM write) or 0901h (EEPROM write mode selection) in the recipient register.
If any one of C096 to C100 is changed, the change will not be reflected until the power is reconnected or a reset is performed (by turning the RS terminal ON and then turning it OFF).

Error Display
Upon detecting an error, the Inverter cuts off (trips) the output, the ALARM LED indicator is lit, and an error code is displayed. By pressing the Increment key while the error code is displayed, the output frequency, current, DC voltage and other detailed information at the time of occurrence of the alarm can be checked.
Before resetting the alarm, check each signal such as the RUN command.
Also before resetting the alarm, identify the cause of the trip based on the displayed error code and remove the cause.
This Chapter explains how to handle problems that may occur after operation of the Inverter is started.
Method for Resetting Trip
A trip can be reset by one of the following two methods:
Press the STOP/RESET Key.
Allocate Reset (18: RS) to a multi-function input terminal, and turn this terminal ON and then turn it OFF.
Depending on its factor, the trip may not be reset using the reset terminal. In this case, reconnect the power supply.

Precautions for Safe Use
Maintenance and Inspection
Be sure to confirm safety before conducting maintenance, inspection or parts replacement.
The life of the capacitor depends on ambient temperatures. Refer to the diagram of product life specified in the manual. When the capacitor stops operating at the end of the product's life, the
Inverter must be replaced.
Precautions for Correct Use
Operation Stop Command
Provide a separate emergency stop switch because the STOP key on the Digital Operator is valid only when function settings are performed.
When checking a signal during the power supply and the voltage is erroneously applied to the control input terminals, the motor may start abruptly. Be sure to confirm safety before checking a signal.
Maintenance and Parts Replacement
The Inverter consists of many parts, and these parts must operate properly in order to make full use of the designed functions of the Inverter. Among the electronic components, there are some that require maintenance depending on their usage conditions. In order to keep the Inverter operating normally over a long period of time, it is necessary to perform periodic inspections and replace parts according to their service life.
Product Disposal
Comply with the local ordinance and regulations when disposing of the product.

Megger Test
For a megger test of the external circuit, be sure to disconnect all the terminals of the Inverter and not to apply the test voltage to the Inverter.Use a 500 V DC megger for a megger test.
Conduct the megger test for the Inverter's main circuit after short-circuiting terminals R/L1, S/
L2, T/L3, U/T1, V/T2, W/T3, RB, +1, P/+2 and N/
− using wires, as shown below.
Conduct an Inverter megger test only to the main circuit, not to the control circuit.
Use a high resistance tester for a power distribution test of the control circuit. Do not use a megger or buzzer.

Motor
Do not connect to the motor.
Withstand Voltage Test
Do not conduct a withstand voltage test on any part of the Inverter.
Doing the test may cause damage or deteriorate to the parts inside the Inverter.
Checking the Inverter and Converter
The quality of the Inverter and converter can be checked using a tester.
Preparation
1. Disconnect the externally connected power supply wires (R/L1, S/L2, T/L3), the motor connection wires (U/T1, V/T2, W/T3), and the generation control resistance
(P/+2, RB).
2. Prepare a tester. (Usable range is 1
Ω measurement resistance.)
Checking method
The quality can be judged by measuring the conduction state of Inverter main circuit terminal blocks R/L1, S/L2, T/L3U/T1, V/T2, W/T3, RB, P/+2, and N/ − while alternating the tester polarity.

8-1 Inspection and Maintenance
Before checking, measure the voltage between P/+2 and N/
− at DC voltage range in advance, and confirm that the smoothing capacitor is sufficiently discharged.
A nearly infinite value is shown in a no-conduction state. (The value shows the range from a few to a few dozen
Ω in a conduction state.)
However, the value may not be infinite if the momentous conduction occurs through the influence of the smoothing capacitor.
The Inverter or converter is in good shape if the values from various parameters are nearly equal, though they are not consistent depending on the types of elements or testers.

*1. Protection method complies with JEM 1030.
*2. To operate the motor at over 50/60 Hz, contact the motor manufacturer to find out the maximum allowable speed of revolution.
*3. For the stable control of the motor, the output frequency may exceed the maximum frequency set in
A004 (A204) by 2 Hz max.
Note 1. The applicable motor is a 3-phase standard motor. For using any other type, be sure that the rated current does not exceed that of the Inverter.
Note 2. Output voltage decreases according to the level of the power supply voltage.
Note 3. The braking torque at the time of capacitor feedback is an average deceleration torque at the shortest deceleration (when it stops from 50 Hz). It is not a continuous regeneration torque. Also, the average deceleration torque varies depending on the motor loss. The value is reduced in operation over 50 Hz.

*1. To use the braking resistor (3G3AX-RAB/-RBB/-RBC) for a regenerative braking unit of the 400 V class, be sure to remove the built-in resistor, and connect 2 resistors of the same model in series.
If the regenerative braking unit of 400 V class is operated with a single braking resistor, the braking resistor may be damaged.
*2. Set the DIP switches.
*3. The built-in resistor incorporates a temperature fuse.
If the alarm terminal is not connected, the fuse may blow out in order to prevent the resistor burning due to overheating.
If the fuse blows out, the built-in resistor must be replaced.

Capacitor life (year)
Note 1: Ambient temperature refers to the temperature measured at the location approximately 5 cm from the bottom center of the Inverter.
Panel interior temperature is applied if the Inverter is stored in a control panel.
Note 2: The smoothing capacitor, which will deteriorate because of the chemical reaction caused by the temperatures of the parts, should normally be replaced once every 10 years (which is the expected design life, and not guaranteed).
However, if the ambient temperature is high, or the Inverter is used with its rated current exceeded, for example, under overload conditions, its life will be significantly shortened.

Appendix-3 Life Alarm Output
Appendix-3 Life Alarm Output
When the product life becomes close to the end for limited life parts including the on-board smoothing capacitor or cooling fan, but excluding the main circuit smoothing capacitor, an alarm can be output through the self-diagnostic function. Use it as a reference of the parts replacement period.
This alarm is output through the self-diagnosis based on the expected design life (not a guaranteed value). Therefore, it has a margin of error depending on your environment or operation conditions.

* 3G3MX2-A2110 and A4150 needs to be installed in a metal cabinet and add ferrite core at the input cable to meet category C1. Unless otherwise category C2.
Important notes
1. Input choke or other equipment is required if necessary to comply with EMC directive from the harmonic distortion point of view (IEC 61000-3-2 and 4).
2. If the motor cable length exceeds 20m, use output choke to avoid unexpected problem due to the leakage current from the motor cable (such as malfunction of the thermal relay, vibration of the motor, etc.).
3. As user you must ensure that the HF (high frequency) impedance between adjustable frequency inverter, filter, and ground is as small as possible.
Ensure that the connections are metallic and have the largest possible contact areas
(zinc-plated mounting plates).
4. Avoid conductor loops that act like antennas, especially loops that encompass large areas.
Avoid unnecessary conductor loops.
Avoid parallel arrangement of low-level signal wiring and power-carrying or noise-prone conductors.
5. Use shielded wiring for the motor cable and all analog and digital control lines.
Allow the effective shield area of these lines to remain as large as possible; i.e., do not strip away the shield (screen) further away from the cable end than absolutely necessary.
With integrated systems (for example, when the adjustable frequency inverter is communicating with some type of supervisory controller or host computer in the same control cabinet and they are connected at the same ground + PE-potential), connect the shields of the control lines to ground + PE (protective earth) at both ends. With distributed systems (for example the communicating supervisory controller or host computer is not in the same control cabinet and there is a distance between the systems), we recommend connecting the shield of the control lines only at the end connecting to the adjustable frequency inverter. If possible, route the other end of the control lines directly to the cable entry section of the supervisory controller or host computer. The shield conductor of the motor cables always must connected to ground + PE at both ends.
To achieve a large area contact between shield and ground + PE-potential, use a PG screw with a metallic shell, or use a metallic mounting clip.
Use only cable with braided, tinned copper mesh shield (type "CY") with 85% coverage.
The shielding continuity should not be broken at any point in the cable. If the use of reactors, contactors, terminals, or safety switches in the motor output is necessary, the unshielded section should be kept as short as possible.
Some motors have a rubber gasket between terminal box and motor housing. Very often, the terminal boxes, and particularly the threads for the metal PG screw connections, are painted.
Make sure there is always a good metallic connection between the shielding of the motor cable, the metal PG screw connection, the terminal box, and the motor housing. If necessary, carefully remove paint between conducting surfaces.

Appendix-4 Notes on Compliance with EC Directives and UL/cUL Standards
6. Take measures to minimize interference that is frequently coupled in through installation cables.
Separate interfering cables with 0.25m minimum from cables susceptible to interference. A particularly critical point is laying parallel cables over longer distances. If two cables intersect
(one crosses over the other), the interference is smallest if they intersect at an angle of 90
° .
Cables susceptible to interference should therefore only intersect motor cables, intermediate circuit cables, or the wiring of a rheostat at right angles and never be laid parallel to them over longer distances.
7. Minimize the distance between an interference source and an interference sink
(interference- threatened device), thereby decreasing the effect of the emitted interference on the interference sink.
You should use only interference-free devices and maintain a minimum distance of 0.25 m from the adjustable frequency inverter.
8. Follow safety measures in the filter installation.
If using external EMC filter, ensure that the ground terminal (PE) of the filter is properly connected to the ground terminal of the adjustable frequency inverter. An HF ground connection via metal contact between the housings of the filter and the adjustable frequency inverter, or solely via cable shield, is not permitted as a protective conductor connection. The filter must be solidly and permanently connected with the ground potential so as to preclude the danger of electric shock upon touching the filter if a fault occurs.
To achieve a protective ground connection for the filter:
Ground the filter with a conductor of at least 10 mm2 cross-sectional area.
Connect a second grounding conductor, using a separate grounding terminal parallel to the protective conductor. (The cross section of each single protective conductor terminal must be sized for the required nominal load).

EMC Recommendations
Use the following checklist to ensure the inverter is within proper operating ranges and conditions.
1. The power supply to 3G3MX2 inverters must meet these specifications:
Voltage fluctuation 10% or less
Voltage imbalance
±3% or less
Frequency variation
±4% or less
Voltage distortion THD = 10% or less
2. Installation measure:
Use a filter designed for
3G3MX2 inverter. Refer to the instruction of the applicable external
EMC filter.
3. Wiring:
Shielded wire (screened cable) is required for motor wiring, and the length must be 20 meter or less.
If the motor cable length exceeds the value shown above, use output choke to avoid unexpected problem due to the leakage current from the motor cable.
The carrier frequency setting must be 2 kHz to satisfy EMC requirements.
Separate the power input and motor wiring from the signal/process circuit wiring.
4. Environmental conditions-when using a filter, follow these guidelines:
Ambient temperature:
−10 to 50°C (Derating is required when the ambient temperature exceeds 40
°C)
Humidity: 20 to 90% RH (non-condensing)
Vibration: 5.9 m/sec2 (0.6 G) 10-55Hz
Location: 1000 meters or less altitude, indoors (no corrosive gas or dust)
Note on Low-voltage Directive
Ensure correct installation and wiring by following the instructions provided in Chapter 2
"Design" of this User's Manual.

Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles, safety equipment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2.
Programmable Products. Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof.
3.
Performance Data. Data presented in Omron Company websites, catalogs and other materials is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
4.
Change in Specifications. Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to confirm actual specifications of purchased Product.
