Notes for Motorvii.....................................................
The VS-625M5 Inverter and VS-656MR5 Converter form a highly reliable, high-performance AC drive system
in which an AC spindle motor is controlled by the Inverter using vector control with a regenerative function.
The system ensures stable drive control of machine tools, such as machining centers and lathes, and industrial
machines, such as transfer machines and testing machines, while providing high speed and the ability to handle
tough environmental conditions.
The system has the following features.
J
Multi-axis Driving
The Inverter and Converter are separate units of highly reliable, compact book-type construction. The
Converter incorporates a power regeneration function and multi-axis driving configuration, providing
power to the spindle drive and servo drive with easy control through the control panel.
J Compact
The Inverter and Converter are more compact and ensure higher precision than conventional models. This
was enabled by the development of a compact, high-precision detector, improvement in output voltage
under optimal vector control, and the selection of an optimum cooling construction as a result of thermal
analysis.
J
Compatible with Yaskawa’s YENET1200 Standard Network
The Inverter and Converter are available in models that are compatible with Yaskawa’s YENET1200 standard high-speed serial network, making it possible to reduce the number of wires for CNC connections.
The Inverter and Converter are also available in models that are compatible with analog I/O interfaces as
well so that the Inverter and Converter can be used with the VS-626 Series for conventional spindle driving. Sequence I/O can be connected to 0- and 24-V common terminals.
J
Compact, Lightweight Spindle Motor
The downsizing of the spindle motor was enabled by the optimum electromagnetic design of the system
ensuring ideal heat distribution, improvements in the core and cooling construction of the system, and
changes in the circuit design of the encoder. The system ensures higher reliability under tough environmental conditions than any conventional system.
J
High-precision, High Servo Performance
The system employs a high-speed IGBT (insulated gate bipolar transistor) power element for high−precision, high-frequency PWM control at high speeds, suppressing current distortion that may cause torque
ripples and reducing rotational fluctuations. The system employs a DSP (digital signal processor) as well
to improve the servo performance of the system.
J
Improved Orientation Function
The system performs orientation control to a fixed position using the motor encoder. This function is used
when the motor shaft is connected to the load shaft at a ratio of one to one. For orientation control with
a magnetic sensor, the detected signal of the motor encoder will be used for orientation control to desired
position.
J
Expanded Fixed Output Range via Winding Selection
If a winding selection motor is used, a dedicated electromagnetic contactor will select the winding, making
it possible to expand the fixed output range without an increase in the capacity of the Inverter. This will
eliminate the speed change mechanism of the machinery to enable downsizing.
J
Continuous Regenerative Operation
The Converter and Inverter employ an IGBT so that the Converter will respond to frequent accelerations
and decelerations, suppress temperature rises, and save energy consumption, improving the rate of power
supply regeneration and enabling regenerative control at high speeds.
J
Construction
Inverter and Converter models with external heatsink cooling are available and panel-mounting construction with an integral cooling fan are provided for ease of panel mounting and maintenance.
1-2
J
International Standards
The Inverter and Converter meet EMC and low-voltage directive requirements, allowing machinery
manufacturers to easily acquire CE marking certification.
1.1.2 Inverter Models
Inverter models are offered in both 200 and 400 V classes. Both M5A models for independent drive with
analog speed references and M5N models for NC systems using YENET1200 serial communications are
available in both classes. M5A and M5N models differ from each other in the host control device and in
connection methods.

2.2 Checking and Controlling the Installation Site
2.2 Checking and Controlling the Installation Site
CAUTION
D Always hold the case when carrying the Inverter.
If the Inverter is held by the front cover, the main body of the Inverter may fall, possibly resulting in injury.
D Mount the Inverter and the Converter on nonflammable material (i.e. metal).
Failure to observe this caution can result in a fire.
D Install a fan or other cooling device to keep the ambient temperature of Inverter and Converter
below 55_C (131_F) and the intake air temperature to heatsink below 45_C(113_F).
Overheating may cause a fire or damage to the unit.
Install the VS-626M5 Inverter and VS-656MR5 Converter in the installation site described below. Maintain
optimum conditions.
2.2.1 Installation Site
Install the Inverter and Converter under the following conditions.
Install the Inverter and Converter in a clean location free from oil mist and water drops. Water or dirty
D
oil inside the Inverter or Converter will decrease the insulation resistance, which may result in a ground
fault. Also, any oil on the electronic components may result in an unforeseeable accident.
Install the Inverter and Converter in a location not in direct sunlight. The interior temperature of the
D
Inverter or Converter exposed to sunlight will increase and exceed the operating ambient temperature,
which may reduce the service life of internal electronic components.
Install the Inverter and Converter in a location free from harmful gasses, liquids, excessive dust, and
D
excessive metal powder. Harmful gasses, corrosion of the electronic or conductive parts, and/or dust
on the Inverter or Converter will decrease the insulation resistance, which may result in a ground fault.
Do not install the Inverter and Converter on combustible material, such as wood.
D
If the Inverter or Converter is installed in a location where the operation conditions are less than ideal
D
because the occurrence of oil mist, install the Inverter or Converter in the oilproof-control panel.
Oil mist in the Inverter or Converter may cause the corrosion of electronic or conductive part, that may
then decrease the insulation resistance, which may result in a ground fault.
If installing the Inverter or Converter in the control panel, care must be taken when planning this installation to prevent oil mist from entering the panel thorough gaps in the welded sections.
Install the Inverter and Converter in a location free from radioactive materials and combustible materi-
D
als.
Install the Inverter and Converter in a location without excessive vibration.
D
Install the Inverter and Converter in a location free from chlorides.
D
Design the ventilation or heat exchanger considering the heat radiation of the Inverter and Converter.
D
Refer to Tables 14.9 to 14.12 for the heat radiation of each Inverter and Converter model. If the ventilation is improper, the heatsink temperature fault protective function will work regardless of whether
or not the output is above the rated value.
D
To cool the Inverter and Converter efficiently, install them vertically. Considering the maintainability
and ventilation of the Inverter and Converter, provide sufficient space on the left, right, top, and bottom
of the Inverter and Converter.Refer to 2.3 Clearance for details. If the ventilation is improper, the heatsink temperature fault protective function will work regardless of whether or not the output is above
the rated value.
D
Although the Inverter and Converter operate between 05C and 555C (325F and 1315F), install the Inverter and Converter so that the maximum temperature of the heatsink inlet air will be 455C (1135F).
If the temperature of the inlet air is excessively high, the heatsink temperature fault protective function
will work regardless of whether or not the output is less than the rated value.
D
Install the Inverter and Converter in a location where the maximum ambient humidity is 90% with no
condensation.
D
The heat dissipation in the control panel can be reduced if the control panel has a ventilation duct and
the heatsink of the Inverter and that of the Converter are exposed in the duct to the cooling air. In this
case, the capacity of the heat exchanger, if required, can be reduced. Refer to 15.5 Inverter/ConverterCooling Design for details.
D
If the Inverter is installed in a panel, the air in the box can be mixed to cool the Inverter. The Inverter
must not be installed outside an enclosure. Although the surface of the PCB is coated with varnish,
the Inverter may fail to operate or result in accidents if the PCB comes in contact with moisture or dust.

Handling
2.2.2 Operating Ambient Temperature
D
2.2.2 Operating Ambient Temperature
To enhance the reliability of operation, the Inverter and Converter should be installed in an environment
free from extreme temperature increases. If the Inverter or Converter is installed in an enclosed environment, such as a panel, use a cooling fan or air conditioner to maintain the internal air temperature below
45°C(113°F).
2.2.3 Protecting the Inverter and Converter from Foreign Matter
Place a cover over the Inverter and Converter during installation to shield them from metal power produced
by drilling.
Always remove the covers from the Inverters and Converters after completing installation. Otherwise,
ventilation will be reduced, causing the Inverter and Converter to overheat.
Observe these additional cautions if taking the heatsink out of the panel from the opening in the control
panel to cool outside.
D
Install an oil-proof gasket on the fitting to prevent oil and dust from entering the unit.
Without a gasket, oil and iron particles may enter the control panel, corrosion of the electronic
parts and conductive parts may occur, and the resulting decrease of the insulation resistance may
result in a ground fault.
D
If oil is on the external cooling fan, decrease in the insulation resistance and in the life of the rotating section may occur over time.
Also, if oil and dust are on the heatsink, cooling efficiency may decrease due to the clogging of
the fins. Attach a filter onto the cooling-air intake and avoid taking in air in locations where the
oil mist is present.
2.2.4 Storage
The Inverter, Converter, and Motor must be stored under the following conditions.
Table 2.2Storage Conditions
Temperature0°Cto60°C (32°F to 140°F)
Humidity5% to 95% with no condensation
The air at 40°C (104°F) with 50% humidity will condensate if the temperature drops to
28°C (82.4°F). Be sure that the place of storage does not have radical temperature changes.

2.5 Motor Installation Precautions
This section provides precautions for mechanical designing around the Motor to be installed.

IMPORTANT
2.5.1 Installation Site
2.5.2 Installation Orientation
The motor flange and shaft are coated with anti-corrosive paint or grease. Clean the flange, shaft, and key
groove with paint thinner before installing the motor.
Install the Motor under the following conditions.
Provide sufficient space so that cooling air will be provided to the cooling fan. Keep a space of at least
D
100 mm (3.94 inches) between the machine and the ventilation outlet of the Motor. If ventilation is
not proper, the motor temperature fault protective function will work regardless of whether or not the
load is at the rated value or not.
Install the motor in a clean location free from oil mist and water drops. If the motor is likely to come
D
in contact with water or oil, protect the motor with a cover. The intrusion of water or dirty oil into the
interior of the motor will decrease the insulation resistance, which may result in a ground fault.
Check that the mounting bed, base, or stand of the Motor is of robust construction because the weight
D
of the motor as well as the dynamic load of the motor in operation will be imposed on it, possibly causing vibration. Use the Motor with a maximum vibration acceleration of 2.5 G if it is a Standard Motor
with a maximum capacity of 22/18.5 kW or a Winding Selection Motor with a maximum capacity of
11/7.5 kW or 18.5/15 or 22/18.5 kW and the external diameter is 260 mm (10.2 inches) or less. Use
the Motor with a maximum vibration acceleration of 2 G if it is a Standard Motor with a maximum
capacity of 37/30 kW or a Winding Selection Motor with a maximum capacity of 15/11 kW and the
external diameter is 260 mm (10.2 inches) or less.
Frequency of vibration acceleration is 10 to 60 Hz (constant amplitude) or 60 to 2,500 Hz (constant
acceleration).
Install the motor in a location free from excessive dust, metal powder, or mist. The motor has a built-in
D
fan that provides cooling air to the core. If the passage of cooling air is blocked with dust or other foreign matter, the cooling efficiency will drop. As a result, the motor temperature fault protective function will work regardless of whether or not the load is the rated value or not.
Use a motor with oil seal in the case, such as gear coupling, where the motor shaft is likely to come
into contact with oil. For gear coupling, check that the surface of lubricating oil is under the oil seal
lip.
Consider the following conditions for the installation direction of the Motor.
The Flange-type Motor can be mounted with the motor shaft on the load side at any angle between
D
horizontal and the downward vertical direction. If the motor shaft is facing up, excessive force will
be imposed on the motor shaft. As a result, the service life of the Motor will be adversely affected.
If the Motor is mounted on legs, mount the legs on the floor. If the legs are installed upward, excessive
D
force will be imposed on the legs. As a result, the service life of the Motor will be adversely affected.
D Use the Motor of outer diameter j380 with the terminal box facing upward and the motor shaft facing
horizontal if it is a Standard Motor with a minimum capacity of 45/37 kW or a Winding Selection
Motor with a minimum capacity of 18.5/15 kW. If the terminal box is in the horizontal or downward
direction, dust may intrude from the ventilation mouth on the bottom of the load-side bracket. As a
result, the Motor may fail to operate or unexpected accidents may occur.

2.5.3 Coupling Motor and Machinery
Consider the following conditions when coupling the Motor with the machinery.
J Direct Coupling
Couple the Motor with the machinery so that the center of the motor shaft and that of the machinery shaft
are on a straight line. Insert a liner for adjustment, if necessary. If the center of the motor shaft does not
coincide with that of the machinery shaft, unnecessary torsion will be imposed on the motor shaft and machinery shaft. As a result, the bearings may wear out or break quickly.
Level
B
A
Fig 2.13Direct Coupling Precision of Motor and Machinery
Use the coupling so that a axial load is not imposed on the motor shaft.
2.5 Motor Installation Precautions
Tolerance A: 0.03 m (0.0012 inches) max.
Surface irregularity B: 0.03 mm (0.0012 inches) max.
2
J Belt Coupling
Check that the motor shaft is parallel to the machinery shaft and that the line connecting the centers of the
pulleys and the shafts are at right angles to each other. The radial load imposed on the motor shaft edge
must not exceed the permissible value specified in 14.2.5 Tolerance Radial Loads.
Be sure that no axial load is imposed on the motor shaft.
If the angularity of the belt is improper, the belt will vibrate or slip. If an excessive radial load is imposed
on the motor shaft, the motor bearings will be adversely affected and the service life of the bearings will
be decreased.
Check that the angle of contact of the belt and pulley will be 140°or more, or otherwise the belt may slip.

Be sure that no axial load is imposed on the motor shaft.
J Mounting a Pulley or Gear to the Motor Shaft
When mounting a pulley or gear to the motor shaft, consider the mounting balance of the Motor. The dynamic balance of the Motor is kept with a half key (for motors with a key way), which is a half as thick
as the key (T) specified in the motor shaft dimensional drawing. The Motor rotates at high speed and a little
imbalance in the mechanism may cause the motor to vibrate.

3.3.5 Wiring the Main Circuit
This section provides information on the main circuits of the Converter and Inverter and information on
wiring the ground lines.
J
Wiring Precautions for Main Circuit Input
Installation of Molded-case Circuit Breaker (MCCB)
Make sure to connect MCCB between the main circuit power supply input and VS-656MR5 input terminals R/L1, S/L2 and T/L3 to protect wiring.
Installation of Ground Fault Interrupter
The output of the Inverter is switched at high speed, which results in high-frequency leakage current. When
connecting a ground fault interrupter to the input terminals of the Converter, select an one designed for
inverters that eliminates the high-frequency leakage current and detects only the leakage current in frequency bands that are harmful to the human body.
D
Use a ground fault interrupter designed for inverters for each Converter, with a minimum sensing current of 30 mA.
D
A standard ground fault interrupter can be used for each Converter provided that it has a minimum
sensing current of 200 mA with a minimum response time of 0.1 s.
Installation of Magnetic Contactor
When the main circuit power supply is shut OFF in the sequence, a magnetic contactor (MC) can be used
instead of a molded-case circuit breaker (MCCB). However, when a magnetic contactor is switched OFF
at the main circuit power supply input side, regenerative braking does not function and the motor coasts
to a stop. (At this time, protective function activates to display a fault.)
Frequent turning ON and OFF the magnetic contactor for the main circuit power supply input may cause
the Converter and Inverter to malfunction. Turn the magnetic contactor ON and OFF once every 30 minutes at most.
3.3 Wiring Main Circuit Terminals
3
IMPORTANT
Terminal Block Connection Sequence
Main circuit power supply input phases can be connected to any terminal regardless of the order of R/L1,
S/L2 and T/L3 on the terminal block.
Installation of AC Reactor
Make sure to install an AC reactor, which corresponds to the capacity of the individual Converter, to each
Converter for the Converter’s power-supply regeneration.
Do not connect any equipment other than the Converter to the secondary side of the AC reactor. If this
caution is not observed, an overcurrent may occur in the Converter.AnACreactor is effective in improving
the power factor of the power supply side.
Installation of Surge Suppressor
For inductive loads (magnetic contactors, magnetic relays, magnetic valves, solenoids, magnetic brakes,
etc.) connected near the inverter, install a surge suppressor.
A surge absorber is used to absorb energy accumulated in the coil of an inductive load. Use a surge absorber
with a capacity suitable for the coil. Do not, however, connect surge absorbers to output terminals U, V, W
of the Inverter. If a surge absorber is not used, the generated surge voltage of the coil will affect the control
signal line of the Inverter when the inductive load is turn ON and OFF. As a result, the control signal may
malfunction.
Prohibition of Installation of Phase Advancing Capacitor
Do not connect a phase advancing capacitor or surge suppressor to main circuit power supply input (R/L1,
S/L2, or T/L3). The phase advancing capacitor or surge suppresser may become overheated and damaged
by the harmonic components of the drive unit. Also, the drive unit may malfunction because of overcurrent.
Using Input Noise Filters
A noise filter installed on the power supply side eliminates external noise on the power line of the Inverter
and suppresses harmonic noise leaking from the Inverter to the power line. Use a noise filter designed for
an inverter, as shown in example 1. Refer to 14.3.7 Noise Filter for recommended filters.

Wiring Precautions for Converter Control Power Supply Input
J
Make sure to connect MCCB with the converter control power supply input terminals A1/r and A2/t to
protect wiring.
Wiring Precautions for Main Circuit between Converter and Inverter
Connecting the Converter Control Power Supply Output
Connect converter control power supply output terminals P1 and N1 to inverter left-side control power
supply input terminals P1 and N1 using exclusive-use power cable.
Wiring Precautions for Inverter Main Circuit Output
J
Connecting the Inverter and Motor
Connect output terminals U/T1, V/T2 and W/T3 to motor lead wires U, V and W. Connection method is
indicated on the back of the terminal cover. Verify that the motor rotates in the forward direction (CCW:
counterclockwise when viewed from the motor load side) with the forward run command.
Strict Prohibition of Connecting Input Power Supply to Output Terminals
Do not connect power to the U/T1, V/T2, or W/T3 output terminals, or otherwise the internal inverter circuits will be damaged.
Strict Prohibition of Shorting or Grounding Output Terminals
Do not touch output terminals directly with your fingers or connect output lines to the Inverter’s case. Electrical shock or a ground short may occur, creating an extremely dangerous situation. Never short the output
lines.
Strict Prohibition of Connection of Phase Advancing Capacitor or Noise Filter
Never connect a phase advancing capacitor or LC/RC noise filter to the output circuit, or otherwise the
Inverter may be destroyed or internal components damaged.
3 -22
Strict Prohibition of Installation of Magnetic Starter
Do not connect a phase advancing capacitor or LC/RC noise filter to the output circuit, or otherwise the
Inverter may be damaged or the internal parts of the Inverter may be damaged.
Dealing with Emission Noise
To reduce the emission noise from output side, wire the signal lines together in a grounded metallic conduit. Make the wiring distance between the power line and signal line 30 cm (11.8 inches) or longer, and
the emission noise will be reduced.
Power
Supply
~
MCCB
VS656MR5
Fig 3.15Dealing with Emission Noise
Wiring Distance between Inverter and Motor
The signal and power cables between the inverter and the motor must be separated and the cable extension
must be as short as possible (20 m (65.6 ft) or less).
Grounding
J
Use the following information to ensure that the ground is sufficient.
D
Make sure to ground the ground terminal ().
200 V class: Ground to 100Ω or less
400 V class: Ground to 10Ω or less
D
Never ground the inverter or the converter in common with welding machines, motors, or other largecurrent electrical equipment. Wiring for grounding cable must be separated from the large-current
electrical equipment.
D
Always use a ground wire that complies with technical standards on electrical equipment. Minimize
the length of the ground wire. Leakage current flows through the Inverter. Therefore, if the distance
between the ground terminal and the ground terminal is too long, the potential on the ground terminal
of the Inverter will become unstable.
D
Always ground converters, inverters and motors using a ground terminal even when equipment is
grounded through sill channel or steel plate.
D
Ground each Converter and Inverter directly to the ground as shown in figure 3.16 (a). Do not make
a loop as shown in (b). Ground the Inverter and motor as shown in figure 3.17 (a). Do not ground both
the Inverter and motor as shown in (b).

3.4.5 Sequence Output Signal Circuit (for Stand-alone Drive)
Design the output signals in consideration of the following conditions.
The output method allows either a +24 V or 0 V common.
D
Signal outputs are insulated with photocouplers. Prepare a +24 V power supply for the output signal.
D
The output current capacity is 50 mA at 24 V.
D
To turn ON and OFF an inductive load, such as an external relay, connect a surge absorber in parallel
D
with the load. The maximum permissible voltage of the output circuit is 26 V. Do not impose a voltage
exceeding the maximum permissible voltage, or otherwise the photocoupler of the output circuit may
be damaged.
If the load is capacitive, connect a protective resistor to the load in series to restrict the current, or other-
D
wise an excessive current will flow when the photocoupler is driven, and as a result, the photocoupler
may be damaged.

3.4.6 Precautions for Control Signal Wiring
IMPORTANT
IMPORTANT
Fig 3.21Output Interface Circuit
For proper wiring between devices, pay attention to the following points in the design stage.
Design the wiring for control signal lines (1, 2, 4CN) in such a way that they will be separated form
D
the main circuit wiring (R/L1, S/L2, T/L3) or other power lines.
If the power lines are provided along with the signal lines (motor encoder signal lines), a malfunction may
be caused by the affect of noise generated from the power lines.
The length of the control signal lines (including motor encoder signal lines) must be less than 20 m
D
(65.6 ft).
Excessively long motor encoder signal lines reduce the encoder power supply voltage because of voltage drop
in the signal lines which may cause the inverter to malfunction.
When shielded twisted-pair cables are used for control signal lines, terminate them as shown below.

FWD/REV (Forward Signal and Reverse Signal)
J
The FWD signal will function when 6CN-8 turns ON.
The REV signal will function when 6CN-9 turns ON.
When the FWD signal is turned ON while the RDY and EMG signals are ON and the speed reference
D
is at a positive voltage, the motor will turn counterclockwise (motor viewed from the shaft end). When
the REV signal is turned ON, the motor will turn clockwise.
The rotation of the motor will be determined by the speed reference and operation signal in combination, as shown below.

D
to operate a maximum of 2.5 s after the EMG signal is turned ON. Do not attempt to charge the capacitor repeatedly within a short period of time, or otherwise the charging circuit will deteriorate quickly.
Allow a sufficient interval to charge the capacitor again.
When the EMG signal is turned OFF, the motor will stop promptly due to regenerating braking and
D
the current will be shut off. If the motor does not stop, the current will be shut off automatically 10 s
after the EMG signal is turned OFF. At that time, the protective function will operate and “AL-21”
(emergency stop failure) will be displayed.
C1-10 (soft start time setting) will be disabled when an emergency stop failure occurs.
D
If the EMG signal is turned OFF, the motor will not operate when the EMG signal turns ON again un-
D
less the FWD, REV, and ORT signals are turned OFF.
While the motor is decelerated in emergency stop operation, the motor will coast to a stop with no re-
D
generation breaking if the magnetic contactor on the Converter input shuts off the main circuit power
supply. At that time, the main circuit low-voltage protective function will operate and a fault will be
indicated.
To prevent the motor from coasting to a stop when shutting off the main circuit power supply in emer-
D
gency stop operation, use the OFF-delay circuit to delay the timing of shutting off the main circuit power supply.
Always turn ON the EMG signal if it is not used. If the 0 V common or 24 V common input method
D
is selected, connect 6CN-7 to 6CN-19. If the external common input method is selected, always turn
the EMG signal ON externally.

Operating the Digital Operator
5.1 Function of the Digital Operator
The Digital Operator enables the following:
J
Display of Control Signal Status
Status of control signals of each unit is displayed by monitoring the status of operation. For the display
items, see Chapter 11 Operating Status Displays.
J
Display and Setup of Control Constants
Control constants must be set up for normal operation in compliance with the specifications.
Chapter 10 Control Constants lists the control constants.
J
Display of Protective Functions
If an error occurs during operation, protective functions are displayed. 12.2 Converter Faults and 12.3 In-
verter Faults list the protective functions. These are not displayed when operation is normal.
J
Functions Using the Digital Operator
Stand-alone operation without sequence input signals or speed reference is possible by using the Digital
Operator. This function is effective for test run of inverter/converter connected only to motor. For the details of the operation, see Par. 5.3 (5) “Digital Operator Operation Mode.”
