The design of the MxC is simpler and more efficient than a conventional inverter. The MxC uses a different
mechanism to generate AC voltage, and relies on nine bi-directional switches to adjust AC output power to the
motor directly from an AC line power input.
The MxC has no rectifying diodes and no DC bus capacitors commonly used in inverters.

Input and Output Wiring in the Main Circuit
This section describes wiring connections for the main circuit inputs and outputs.
Wiring Main Circuit Inputs
Observe the following precautions when wiring inputs for the main circuit power supply.
Installing a Molded-Case Circuit Breaker
Always connect the power input terminals (R, S, and T) and power supply via a molded-case circuit breaker
(MCCB) suitable for the MxC.
• Choose an MCCB with a capacity of 1.5 to 2 times larger than the rated current of the MxC.
• The MCCB operation time should reflect the overload protection time of the MxC.
• If the same MCCB is to be used for more than one MxC or in other devices, set up a sequence so that the
power supply will be turned off by a fault output, as shown in Fig 2.8.
Fig 2.8 MCCB Installation
Installing a Ground Fault Interrupter
MxC outputs use high-speed switching, causing high-frequency leakage current to be generated. A ground
fault interrupter with countermeasures for high-frequency distortion is therefore needed on the primary side of
the MxC in order to detect any hazardous leakage current within the frequency, and to exclude that high-frequency leakage current.
• When deciding to use a ground fault interrupter with countermeasures for high-frequency distortion
choose one with a sensitivity amperage of at least 30 mA per MxC.
• A general ground fault interrupter without countermeasures for high-frequency distortion is not recom-
mended. If a general ground fault interrupter malfunctions, replace it with a ground fault interrupter with a
sensitivity amperage of 200 mA or more per MxC and with an operating time of 0.1 s or more.

Generalpurpose

If the power supply for the main circuit gets shut off during a sequence, a magnetic contactor can be used to
stop the MxC.
When a magnetic contactor is installed on the primary side of the main circuit to forcibly stop the MxC,
regenerative braking does not work and the MxC will simply coast freely until it stops.
• The MxC can be started and stopped by opening and closing the magnetic contactor on the primary side.
Frequently opening and closing the magnetic contactor, however, may cause the MxC to malfunction. The
MxC should not be started and stopped more than once every 30 minutes.
• The unit cannot be restarted automatically following an interruption in the power supply when using the
digital operator to control the MxC.
Connecting Input Power Supply to the Terminal Block
An input power supply can be connected to terminals R, S, or T on the terminal block. The phase sequence of
the input power supply is irrelevant to the phase sequence created by the MxC.
Installing a Surge Absorber
Always use a surge absorber or diode for inductive loads near the MxC. Examples of inductive loads include
magnetic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.
Installing a Noise Filter on Power Supply Side
Install a noise filter to eliminate noise transmitted between the power line and the MxC.

Do not use general-purpose noise filters. No generalpurpose noise filter can effectively suppress noise
generated from the MxC.
Wiring Main Circuit Terminals
Wiring the Output Side of the Main Circuit
Observe the following precautions when wiring the main output circuits.
Connecting the MxC and Motor
Connect output terminals U, V, and W to motor lead wires U, V, and W, respectively.
Make sure the motor rotates forward when the Forward Run Command is given. Switch over any two of the
output terminals to each other and reconnect if the motor rotates in reverse with the Forward Run Command.
Never Connect a Power Supply to Output Terminals
Never connect a power supply to output terminals U, V, and W. Applying voltage to the output terminals will
damage circuitry in the MxC.
Never Short or Ground Output Terminals
If you touch the output wires with your bare hands, or if the output wires come into contact with the MxC casing, an electric shock or grounding will occur. This is extremely hazardous. Do not short the output wires.
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never connect a phase advancing capacitor or general (LC/RC) noise filter to an output circuit. The high-frequency components of the MxC output may result in overheating or damage to these parts, or may result in
damage to the MxC or cause other parts to burn.
Do Not Use an Electromagnetic Switch
Never connect an electromagnetic switch (MC) between the MxC and motor and then cycle power while the
MxC is running. If the MC is turned on while the MxC is operating, a large current inrush will trigger overcurrent or overvoltage protection.
When using an MC to switch over to a commercial power supply, stop the MxC and motor before operating
the MC. Use the speed search function if the MC is either open or closed while running. If action must be
taken to handle any momentary interruption in power, use a delayed release MC.
Installing a Thermal Overload Relay
This MxC has an electronic thermal protection function to protect the motor from overheating. If a multi-pole
motor is used, always install a thermal relay (THR) between the MxC and the motor, then set L1-01 to 0 (no
motor protection). The sequence should be designed so that the thermal overload relay contacts turn off the
magnetic contactor on the main circuit inputs.
Installing a Noise Filter on Output Side
Connect a noise filter to the output side of the MxC to reduce radio noise and inductive noise. Refer to Chapter 9 Specifications for details.
Power
supply
Inductive Noise: Electromagnetic induction generates noise on the signal line, and may cause the controller to malfunction.
Radio Noise: Electromagnetic waves from the MxC and cables can cause the broadcasting radio receiver to make noise.

As described previously, a noise filter can be used to prevent inductive noise from being generated on the output side. Alternatively, cables can be routed through a grounded metal pipe to prevent inductive noise. Keeping the metal pipe at least 30 cm away from the signal line considerably reduces inductive noise.
Fig 2.12 Countermeasures Against Inductive Noise
Counteracting RMS
Radio noise is generated from the MxC as well as from the input and output lines. To reduce radio noise,
install noise filters on both input and output sides, and also install the MxC in a totally enclosed steel box.
The cable between the MxC and the motor should be as short as possible.
Fig 2.13 Countermeasures Against Radio Interference
Cable Length between the MxC and Motor
If the cable between the MxC and the motor is comparatively long, the high-frequency leakage current will
increase, causing the MxC output current to increase as well. This may affect peripheral devices. To prevent
this, adjust the carrier frequency (set in C6-01, C6-02) as shown in Table 2.5 (for details, refer to Chapter 5Parameters and Settings).

Ground Wiring
Observe the following precautions when grounding the MxC.
• Always use the ground terminal of the 200 V MxC with a ground resistance of less than 100 Ω and that of
the 400 V MxC with a ground resistance of less than 10 Ω.
• Do not share the ground wire with other devices, such as welding machines or power tools.
• Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
Leakage current flows through the MxC. Therefore, if the distance between the ground electrode and the
ground terminal is too long, potential on the ground terminal of the MxC will become unstable.
• When using more than one MxC, be careful not to loop the ground wire.

Wire Gauges and Closed-Loop Connectors
For remote operation using an analog signal, keep the control line length between the digital operator or operation signals and the MxC to 50 m or less, and separate the lines from high-power lines (main circuits or relay
sequence circuits) to reduce induction from peripheral devices.
When setting frequencies from an external device (i.e., not from the digital operator), use shielded twisted-pair
wires and ground the shield to terminal E (G), as shown in the following diagram.

Wiring Method and Precautions
The wiring method is the same as the one used for straight solderless terminals. Refer to page 2-17. Observe
the following precautions when wiring:
• Separate the control signal lines for the PG Speed Control Card from main circuit lines and power lines.
• Connect the shield when connecting to a PG. The shield must be connected to prevent operational errors
caused by noise. Also, do not use any lines that are more than 100 m long. Refer to Fig 2.21 for details on
connecting the shield.
• Connect the shield to the shield terminal (E), but only if the MxC is not affected by noise from peripheral
devices.
• Do not solder the wire ends. Doing so may cause a contact fault.
• When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm.

Operation Modes
This section describes the operation modes available in the MxC, and how to switch between modes.
MxC Modes
Parameters and monitoring functions in the MxC are organized into groups called “modes”. These modes
make it easier to read and set parameters. Their are five separate modes available in the MxC.
The five modes and their primary functions are shown in the Table 3.3.
Table 3.3 Modes
ModePrimary functions
A Run Command may be entered to start the motor when viewing this mode.
Drive Mode
Quick Programming Mode
Use this mode when monitoring values such as frequency references or output current, displaying fault information, or displaying the fault history.
Use this mode to set and monitor the most commonly used parameters, as well as
operate the MxC.
Operation Modes
Advanced Programming ModeUse this mode to reference and set all parameters.
Verify Mode
Auto-Tuning Mode*
* Always perform Auto-Tuning with the motor before operating in Open Loop or Flux Vector Control. The Auto-Tuning Mode cannot be entered while the
MxC is running, or when an error has occurred. The default setting of the MxC is for Open Loop Vector Control (A1-02 = 2).
Use this mode to read/set parameters that have been changed from their original
default values.
Use this mode when running a motor with unknown motor characteristics in Open
Loop or Flux Vector Control. In this mode, the MxC automatically calculates the
motor characteristics, then enters those values to the motor parameters.
Also used to measure the motor line-to-line resistance.

Auto-Tuning Mode
This menu is used to Auto-Tune the MxC in order to calculate the required motor parameters to optimize
motor performance. Ideally, perform Auto-Tuning with the motor uncoupled from the load.
When the motor cannot be disconnected from the load, perform static or terminal resistance Auto-Tuning. To
set motor parameters manually, contact your Yaskawa representative. Follow the key operations in Fig 3.9 to
access the Auto-Tuning Menu.
The MxC’s Auto-Tuning function automatically determines the optimal motor parameters settings. This is
fundamentally different from the Auto-Tuning function in a servo system, which instead determines the size of
a load. The default setting of the MxC is for Open Loop Vector Control.
The display will

change depending
on the status of
autotuning.

Executing Auto-Tuning
Set the motor output power (kW), rated voltage, rated current, rated frequency, rated speed, and number of
poles as specified on the motor nameplate. Next, press RUN. The motor will begin to rotate, and the MxC will
automatically set motor parameters based on the information provided from the nameplate and measurements
taken during the Auto-Tuning process.
Auto-Tuning requires that motor data be entered from the specifications indicated on the motor nameplate.
Auto-Tuning cannot be executed without this information, and cannot be started from the motor rated voltage
display.
Set parameter values when they are displayed by using the up, down, and right arrow keys. Changes are saved
once DATA/ENTER key is pushed.
The following example shows how to perform Auto-Tuning in the Open Loop Vector Control Method while
operating the motor (without switching to motor 2).
Fig 3.9 Screen Displays in the Auto-Tuning Mode
The screen displays in the Auto-Tuning Mode depend on the control method the MxC is operating in (V/f,
Open Loop Vector, or Flux Vector). If a fault occurs during Auto-Tuning, refer to Chapter 7 Troubleshooting.

This section describes the procedure for performing a test run after the MxC is fully connected.
Switching the Power On
Confirm all of the following items first, and then turn on the power supply.
• Make sure the power supply voltage is correct.
200 V class: 3-phase 200 to 220 VDC, 50/60 Hz
400 V class: 3-phase 380 to 480 VDC, 50/60 Hz
If connecting an MxC to a power supply with high impedance, such as a Slidax, the power-supply voltage
may rise during regeneration. Contact your Yaskawa representative for details.
• Use a power supply with a capacity that is the same or greater than the MxC capacity.
• Make sure that the motor output terminals (U, V, W) and the motor are properly connected.
• Make sure that the MxC control circuit terminal and the control device are wired correctly.
• Set all MxC control circuit terminals to off.
• When using a PG Speed Control Card, make sure that it is wired correctly.
• Make sure that the motor is not connected to the mechanical system (no-load status)

Auto-Tuning
Use the following procedure to perform Auto-Tuning if using the vector control method or when using a long
motor cable. Auto-Tuning calculates the motor characteristics and automatically sets all necessary motor
parameters.
If the control method was changed after Auto-Tuning, be sure to perform Auto-Tuning again.
The following types of Auto-Tuning are possible in the MxC:
• Rotational Auto-Tuning
• Stationary Auto-Tuning for line-to-line resistance only
• Stationary Auto-Tuning 2
Precautions Before Performing Auto-Tuning
Read the following precautions before Auto-Tuning the MxC.
• Auto-Tuning the MxC is fundamentally different from Auto-Tuning a servo system. The MxC Auto-Tun-
ing automatically adjusts motor parameter settings according to detected motor characteristics, whereas
servo system Auto-Tuning adjusts parameters according to the size of the load.
• When speed or torque precision is required at high speeds (i.e., 90% of the rated speed or higher), use a
motor with a rated voltage that is 20 V less than the input power supply voltage of the MxC for 200V class
MxCs and 40 V less for 400V class MxCs. If the rated voltage of the motor is the same as the input power
supply voltage, the voltage output from the MxC will be unstable at high speeds and sufficient performance will not be possible.
• Use Stationary Auto-Tuning 2 whenever performing Auto-Tuning for a motor that is connected to a load.
• Use Rotational Auto-Tuning whenever performing Auto-Tuning for a motor that has fixed output charac-
teristics, when high precision is required, or for a motor that is not connected to a load.
• If Rotational Auto-Tuning is performed on a motor connected to a load, the MxC will be unable to accu-
rately calculate the best motor parameters, which may cause the motor to exhibit operate abnormally.
Never perform Rotational Auto-Tuning on a motor connected to a load.
• If the wiring between the MxC and motor changes by 50 m or more between Auto-Tuning and motor
installation, perform Stationary Auto-Tuning for line-to-line resistance only.
• If the motor cable is long (50 m or longer), perform Stationary Auto-Tuning for line-to-line resistance only,
even when using V/f Control.
• The table below shows the status of the multi-function inputs and multi-function outputs during Auto-Tun-
ing. When performing Auto-Tuning with the motor connected to a load, be sure that the holding brake is
not applied during Auto-Tuning, especially when working with conveyor systems or similar equipment.

Selecting the Best Auto-Tuning Mode
Rotational Auto-Tuning (T1-01 = 0)
Rotational Auto-Tuning is used for Open Loop Vector Control and Flux Vector Control. Set T1-01 to 0, input
the data from the nameplate, and then press the RUN key on the digital operator. The MxC will stop the motor
for approximately one minute and then set the required motor parameters automatically while operating the
motor for approximately one minute.
1. Always disconnect the motor from the machine and confirm that it is safe to operate the motor before
performing Rotational Auto-Tuning.
2. If the motor cannot be operated by itself, perform Stationary Auto-Tuning, but always use Rotational
Auto-Tuning whenever it is possible to operate the motor by itself to increase performance.
Stationary Auto-Tuning for Line-to-Line Resistance Only (T1-01 = 2)
Stationary Auto-Tuning for line-to-line resistance only can be used in any control method. This is the only
Auto-Tuning possible for V/f Control Method and V/f Control Method with a PG encoder.
Auto-Tuning can be used to prevent control errors when the motor cable is long (50 m or longer) or the cable
length has changed since installation or when the motor and MxC have different capacities.
Set T1-01 to 2, and then press the RUN key on the digital operator. The MxC will supply power to the stationary motor for approximately 20 seconds and the Motor Line-to-Line Resistance (E2-05) and cable resistance
will be automatically measured.
1. Power will be supplied to the motor when Stationary Auto-Tuning for line-to-line resistance is performed even though the motor will not turn. Do not touch the motor until Auto-Tuning has been completed.
2. When performing Stationary Auto-Tuning connected to a conveyor or other machine, ensure that the
holding brake is not activated during Auto-Tuning.
Stationary Auto-Tuning 2 (T1-01 = 4)
Stationary Auto-Tuning 2 is used for Open Loop Vector Control and Flux Vector Control. Set T1-04 to 4, and
Motor No-Load Current (T1-09) will be added. Input the data written on the motor nameplate. Be sure to input
the value or motor no-load current (motor exciting current) from motor examination results to T1-09. After
Auto-Tuning, the value of T1-09 will be written in E1-03. When not setting T1-09, the no-load current value
of Yaskawa standard motor will be written in E1-03.
1. Power will be supplied to the motor when Stationary Auto-Tuning 2 is performed even though the
motor will not turn. Do not touch the motor until Auto-Tuning is complete.
2. When performing Stationary Auto-Tuning 2 connected to a conveyor or other machine, ensure that the
holding brake is not activated during Auto-Tuning.
Precautions for Rotational and Stationary Auto-Tuning
Lower the base voltage based on Fig 4.3 to prevent saturation of the MxC’s output voltage when the rated
voltage of the motor is higher than the voltage of the power supply to the MxC. Use the following procedure
to perform Auto-Tuning.
1. Input the voltage of the input power supply to T1-03 (Motor Rated Voltage).
2. Input the results of the following formula to T1-05 (Motor Base Frequency):
(Base frequency from the motors nameplate × setting of T1-03)/(Rated voltage from motors nameplate)
3. Perform Auto-Tuning.

1. When more speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03
(Motor Rated Voltage) to the input power supply voltage × 0.85.
2. When operating at high speeds (i.e., 90% of the rated speed or higher), the output current will increase as
the input power supply voltage is reduced. Be sure to provide sufficient margin in the MxC current.
Precautions After Using Rotational and Stationary Auto-Tuning
If the values of the maximum output frequency and the base frequency differ, set E1-04 (Maximum Output
Frequency) after Auto-Tuning.

Application Settings
Parameters are set as required in Advanced Programming Mode (“ADV” will be displayed on the LCD
screen). All the parameters that can be set in Quick Programming Mode can also be displayed and set in
Advanced Programming Mode.
Setting Examples
The following are examples of settings for applications.
• To prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.
• To increase the speed of a 60 Hz motor by 10%, set E1-04 to 66.0 Hz.
• To use a 0 V to 10 V analog signal for a 60 Hz motor for variable-speed operation between 0 and 54 Hz
(0% to 90% speed deduction), set H3-02 to 90.0%.
• To control speed between 20% and 80% to ensure smooth gear operation and limit the maximum speed of
the machine, set d2-01 to 80.0% and set d2-02 to 20.0%.
No-load Operation
To being no-load operation (without connecting the machine and the motor), press the LOCAL/REMOTE key
on the digital operator to change to Local Mode (the SEQ and REF indicators on the digital operator should be
off).
Always confirm safety around the motor and connected machinery before starting MxC operation from the
digital operator. Confirm that the motor works normally and that no errors are displayed.
Jog Frequency Reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and releasing the
JOG key on the digital operator. If the external sequence prevents operation from the digital operator, confirm
that emergency stop circuits and machine safety mechanisms are functioning, and then start running the motor
in Remote Mode (i.e., with a signal from the control signal terminals). The safety precautions must always be
taken before starting the MxC with the motor connected to the machine.
Both a Run Command (forward or reverse) and a frequency reference (or multi-step speed reference) must
be provided to start MxC operation.
Input these commands and reference regardless of the operation method (i.e., LOCAL or REMOTE).
Loaded Operation
4-12
Connect the machine to the motor and then start operation as described for no-load operation (i.e., from the
digital operator or by using control circuit terminal signals).
Connecting the Load
• After confirming that the motor has stopped completely, connect the mechanical system.
• Be sure to tighten all the screws when securing the motor shaft to the mechanical system.
Test Run Procedures
Operation using the Digital Operator
• Use the digital operator to start operation in Local Mode in the same way as in no-load operation.
• If a fault occurs during run, make sure the STOP key on the digital operator is easily accessible.
• At first, set the frequency reference to a low speed of one tenth the normal operating speed.
Checking Operating Status
• Having checked that the operating direction is correct and that the machine is operating smoothly at slow
speed, increase the frequency reference.
• After changing the frequency reference or the rotation direction, check that there is no oscillation or abnor-
mal sound from the motor. Check the monitor display to ensure that U1-03 (Output Current) is not too
high.
• Refer to Notes on Tuning the MxC on page 4-14 if hunting, oscillation, or other problems originating in the
control system occur.
Saving Parameters
Use the Verify Mode (“VERIFY” will be displayed on the LCD screen) to check parameters that have been
changed for Test Run. Those values are then saved as parameters.
Any parameters that have been change by Auto-Tuning will also be displayed in Verify Mode.
If required, the copy function in parameters o3-01 and o3-02 displayed in Advanced Programming Mode can
be used to copy the settings that were changed in the MxC to the memory in the digital operator. If setting
changes are saved to the digital operator, they can be easily copied back to the MxC to speed up system recovery if for any reason the MxC has to be replaced.
The following functions can also be used to manage parameters.
• Saving parameters
• Setting access levels for parameters
• Setting a password
Initializing the MxC with Parameters (o2-03)
If o2-03 is set to 1 after completing a Test Run, parameters will be saved in the MxC. Later, after MxC settings
have been changed further, the MxC can be reset back the parameters values that were saved earlier. All
parameters are saved to a separate area of the memory that can be accessed by performing a “user initialization” (A1-03 = 1110).
Parameter Access Levels (A1-01)
A1-01 can be set to 0 (monitoring-only) to prevent parameters from being changed. A1-01 can also be set to 1
(User-Specified Parameters) and used along with A2 parameters to display only parameters required by the
machine or application in a Programming Mode.
Password (A1-04 and A1-05)
When the access level is set to monitoring-only (A1-01 = 0), a password can be set so that parameters will be
displayed only when the correct password is input.

Notes on Tuning the MxC
Precautions While Tuning the MxC
• Do not change the Torque Compensation Gain (C4-01) from its default setting of 1.00 when using Open
Loop Vector Control.
• If speeds are inaccurate during regeneration in Open Loop Vector Control, enable Slip Compensation Dur-
ing Regeneration (C3-04 = 1).
• Use slip compensation to improve speed control during V/f Control Method (A1-02 = 0).
Set the Motor Rated Current (E2-01), Motor Rated Slip (E2-02), and Motor No-Load Current (E2-03), and
then adjust the Slip Compensation Gain (C3-01) to between 0.5 and 1.5. The default setting for V/f Control
Method is C3-01 = 0.0 (slip compensation disabled).
The following parameters will also indirectly affect the control system:
Table 4.4 Parameters Indirectly Affecting Control and Applications
ParametersApplication
Dwell Function (b6-01 to b6-04)Used for heavy loads or large machine backlashes.
Droop Function (b7-01, b7-02)
Used to soften the torque or to balance the load between two motors. Can
be used when the Control Method Selection (A1-02) is set to 3.
Accel/Decel Times (C1-01 to C1-11)Adjust torque during acceleration and deceleration.
S-Curve Characteristics (C2-01 to C2-04)Used to prevent shock when completing acceleration.
Jump Frequencies (d3-01 to d3-04)Used to avoid resonance points during run.
Analog Input Filter Time Constant (H3-12)Used to prevent fluctuations in analog input signals caused by noise.
Stall Prevention
(L3-01 to L3-03, L3-05, L3-06)
Torque Limits
(L7-01 to L7-04, L7-06, L7-07)
Feed Forward Control (n5-01 to n5-03)
Used to prevent overvoltage errors and motor stalling for heavy loads or
rapid accel/decel. Stall prevention is enabled by default and the setting
does not normally need to be changed.
Set the maximum torque during vector control. If a setting is increased,
use a motor with higher capacity than the MxC. If a setting is reduced,
stalling can occur under heavy loads.
Used to increase response for accel/decel or to reduce overshooting when
there is low machine rigidity and the gain of the speed controller (ASR)
cannot be increased. The inertia ratio between the load and motor and the
acceleration time of the motor running alone must be set.
