For Safe Use

Mitsubishi CNC is designed and manufactured solely for applications to machine tools to be used for industrial purposes. Do not use this product in any applications other than those specified above, especially those which are substantially influential on the public interest or which are expected to have significant influence on human lives or properties.

1. Electric shock prevention

Make sure the power is shut OFF before connecting a unit and a motor to the power.

Do not open the front cover while the power is ON or during operation. Failure to observe this could lead to electric shocks.

Do not operate the unit with the front cover removed. The high voltage terminals and charged sections will be exposed, and can cause electric shocks.

Do not remove the front cover and connector even when the power is OFF unless carrying out wiring work or periodic inspections. The inside of the units is charged, and can cause electric shocks.

Since the high voltage is supplied to the main circuit connector while the power is ON or during operation, do not touch the main circuit connector with an adjustment screwdriver or the pen tip. Failure to observe this could lead to electric shocks.

Wait at least 15 minutes after turning the power OFF, confirm that the CHARGE lamp has gone out, and check the voltage between P and N terminals with a tester, etc., before starting wiring, maintenance or inspections. Failure to observe this could lead to electric shocks.

Ground the unit and motor. For the motor, ground it via the drive unit.

Wiring, maintenance and inspection work must be done by a qualified technician.

Wire the servo drive unit and servo motor after installation. Failure to observe this could lead to electric shocks.

Do not touch the switches with wet hands. Failure to observe this could lead to electric shocks.

Do not damage, apply forcible stress, place heavy items on the cables or get them caught. Failure to observe this could lead to electric shocks.

Always insulate the power terminal connection section. Failure to observe this could lead to electric shocks.

After assembling the built-in IPM/SPM spindle motor, if the rotor is rotated by hand etc., voltage occurs between the terminals of lead. Take care not to get electric shocks.

WARNING

2. Injury prevention

When handling a motor, perform operations in safe clothing.

In the system where the optical communication with CNC is executed, do not see directly the light generated from CN1A/CN1B connector of drive unit or the end of cable. When the light gets into eye, you may feel something is wrong for eye. (The light source of optical communication corresponds to class1 defined in JISC6802 or IEC60825-1.)

The linear servo motor, direct-drive motor and built-in IPM/SPM spindle motor uses permanent magnets in the rotor, so observe the following precautions. (1)Handling

• The linear servo motor, direct-drive motor and built-in IPM/SPM spindle motor could adversely affect medical electronics such as pacemakers, etc., therefore, do not approach the rotor.

• Do not place magnetic materials as iron.

• When a magnetic material as iron is placed, take safety measure not to pinch fingers or hands due to the magnetic attraction force.

• Remove metal items such as watch, piercing jewelry, necklace, etc.

• Do not place portable items that could malfunction or fail due to the influence of the magnetic force.

• When the rotor is not securely fixed to the machine or device, do not leave it unattended but store it in the package properly.

• When installing the motor to the machine, take it out from the package one by one, and then install it.

• It is highly dangerous to lay out the motor or magnetic plates together on the table or pallet, therefore never do so.

(2)Transportation and storage

• Correctly store the rotor in the package to transport and store.

• During transportation and storage, draw people's attention by applying a notice saying "Strong magnet-Handle with care" to the package or storage shelf.

• Do not use a damaged package.

(3)Installation

• Take special care not to pinch fingers, etc., when installing (and unpacking) the linear servo motor.

WARNING

1. Fire prevention

Install the units, motors and regenerative resistor on non-combustible material. Direct installation on combustible material or near combustible materials could lead to fires.

Always install a circuit protector and contactor on the servo drive unit power input as explained in this manual. Refer to this manual and select the correct circuit protector and contactor. An incorrect selection could result in fire.

Shut off the power on the unit side if a fault occurs in the units. Fires could be caused if a large current continues to flow.

When using a regenerative resistor, provide a sequence that shuts off the power with the regenerative resistor's error signal. The regenerative resistor could abnormally overheat and cause a fire due to a fault in the regenerative transistor, etc.

The battery unit could heat up, ignite or rupture if submerged in water, or if the poles are incorrectly wired.

Cut off the main circuit power with the contactor when an alarm or emergency stop occurs.

2. Injury prevention

Do not apply a voltage other than that specified in this manual, on each terminal. Failure to observe this item could lead to ruptures or damage, etc.

Do not mistake the terminal connections. Failure to observe this item could lead to ruptures or damage, etc.

Do not mistake the polarity (+,- ). Failure to observe this item could lead to ruptures or damage, etc.

Do not touch the radiation fin on unit back face, regenerative resistor or motor, etc., or place parts (cables, etc.) while the power is turned ON or immediately after turning the power OFF. These parts may reach high temperatures, and can cause burns or part damage.

Structure the cooling fan on the unit back face, etc., so that it cannot be touched after installation. Touching the cooling fan during operation could lead to injuries.

Take care not to suck hair, clothes, etc. into the cooling fan.

CAUTION

3. Various precautions

(Note) For details, confirm each unit or motor specifications in addition.

When disinfectants or insecticides must be used to treat wood packaging materials, always use methods other than fumigation (for example, apply heat treatment at the minimum wood core temperature of 56 °C for a minimum duration of 30 minutes (ISPM No. 15 (2009))). If products such as units are directly fumigated or packed with fumigated wooden materials, halogen substances (including fluorine, chlorine, bromine and iodine) contained in fumes may contribute to the erosion of the capacitors. When exporting the products, make sure to comply with the laws and regulations of each country.

Do not use the products in conjunction with any components that contain halogenated flame retardants (bromine, etc). Failure to observe this may cause the erosion of the capacitors.

Securely fix the servo motor to the machine. Insufficient fixing could lead to the servo motor slipping off during operation.

Always install the servo motor with reduction gear in the designated direction. Failure to do so could lead to oil leaks.

Structure the rotary sections of the motor so that it can never be touched during operation. Install a cover, etc., on the shaft.

When installing a coupling to a servo motor shaft end, do not apply an impact by hammering, etc. The encoder could be damaged.

Do not apply a load exceeding the tolerable load onto the servo motor shaft. The shaft could break.

Store the motor in the package box.

When inserting the shaft into the built-in IPM/SPM spindle motor, do not heat the rotor higher than 130°C. The magnet could be demagnetized, and the specifications characteristics will not be ensured.

Always use a nonmagnetic tool (explosion-proof beryllium copper alloy safety tool: NGK Insulators, etc.) when installing the built-in IPM/SPM spindle motor, direct-drive motor and linear servo motor.

Always provide a mechanical stopper on the end of the linear servo motor's travel path.

If the unit has been stored for a long time, always check the operation before starting actual operation. Please contact the Service Center, Sales Office or dealer.

(2) Wiring

Correctly and securely perform the wiring. Failure to do so could lead to abnormal operation of the motor.

Do not install a condensing capacitor, surge absorber or radio noise filter on the output side of the drive unit.

Correctly connect the output side of the drive unit (terminals U, V, W). Failure to do so could lead to abnormal operation of the motor.

When using a power regenerative power supply unit, always install an AC reactor for each power supply unit.

In the main circuit power supply side of the unit, always install an appropriate circuit protector or contactor for each unit. Circuit protector or contactor cannot be shared by several units.

Always connect the motor to the drive unit's output terminals (U, V, W).

Do not directly connect a commercial power supply to the servo motor. Failure to observe this could result in a fault.

When using an inductive load such as a relay, always connect a diode as a noise measure parallel to the load.

When using a capacitance load such as a lamp, always connect a protective resistor as a noise measure serial to the load.

Do not reverse the direction of a diode which connect to a DC relay for the control output signals such as contractor and motor brake output, etc. to suppress a surge. Connecting it backwards could cause the drive unit to malfunction so that signals are not output, and emergency stop and other safety circuits are inoperable.

Do not connect/disconnect the cables connected between the units while the power is ON.

Securely tighten the cable connector fixing screw or fixing mechanism. An insecure fixing could cause the cable to fall off while the power is ON.

When using a shielded cable instructed in the instruction manual, always ground the cable with a cable clamp, etc. (Refer to "EMC Installation Guidelines")

Always separate the signals wires from the power line.

Use wires and cables that have a wire diameter, heat resistance and flexibility that conforms to the system.

(3) Trial operation and adjustment

Check and adjust each program and parameter before starting operation. Failure to do so could lead to unforeseen operation of the machine.

Do not make remarkable adjustments and changes of parameter as the operation could become unstable.

The usable motor and unit combination is predetermined. Always check the combinations and parameters before starting trial operation.

The direct-drive motor and linear servo motor do not have a stopping device such as magnetic brakes. Install a stopping device on the machine side.

When using the linear servo motor for an unbalance axis, adjust the unbalance weight to 0 by installing an air cylinder, etc. on the machine side. The unbalance weight disables the initial magnetic pole adjustment.

CAUTION

(4) Usage methods

In abnormal state, install an external emergency stop circuit so that the operation can be stopped and power shut off immediately.

Turn the power OFF immediately if smoke, abnormal noise or odors are generated from the unit or motor.

Do not disassemble or repair this product.

Never make modifications.

When an alarm occurs, the machine will start suddenly if an alarm reset (RST) is carried out while an operation start signal (ST) is being input. Always confirm that the operation signal is OFF before carrying out an alarm reset. Failure to do so could lead to accidents or injuries.

Reduce magnetic damage by installing a noise filter. The electronic devices used near the unit could be affected by magnetic noise. Install a line noise filter, etc., if there is a risk of magnetic noise.

Use the unit, motor and regenerative resistor with the designated combination. Failure to do so could lead to fires or trouble.

The brake (magnetic brake) of the servo motor are for holding, and must not be used for normal braking.

There may be cases when holding is not possible due to the magnetic brake's life, the machine construction (when ball screw and servo motor are coupled via a timing belt, etc.) or the magnetic brake's failure. Install a stop device to ensure safety on the machine side.

After changing the programs/parameters or after maintenance and inspection, always test the operation before starting actual operation.

Do not enter the movable range of the machine during automatic operation. Never place body parts near or touch the spindle during rotation.

Follow the power supply specification conditions given in each specification for the power (input voltage, input frequency, etc.).

Set all bits to "0" if they are indicated as not used or empty in the explanation on the bits.

Do not use the dynamic brakes except during the emergency stop. Continued use of the dynamic brakes could result in brake damage.

If a circuit protector for the main circuit power supply is shared by several units, the circuit protector may not activate when a short-circuit fault occurs in a small capacity unit. This is dangerous, so never share the circuit protector.

Mitsubishi spindle motor is dedicated to machine tools. Do not use for other purposes.

(5) Troubleshooting

If a hazardous situation is predicted during power failure or product trouble, use a servo motor with magnetic brakes or install an external brake mechanism.

Always turn the main circuit power of the motor OFF when an alarm occurs.

If an alarm occurs, remove the cause, and secure the safety before resetting the alarm.

CAUTION

(6) Maintenance, inspection and part replacement

Always backup the programs and parameters before starting maintenance or inspections.

The capacity of the electrolytic capacitor will drop over time due to self-discharging, etc. To prevent secondary disasters due to failures, replacing this part every five years when used under a normal environment is recommended. Contact the Service Center, Service Station, Sales Office or dealer for repairs or part replacement.

Never perform a megger test (measure the insulation resistance) of the drive unit. Failure to observe this could lead to faults.

If the battery low warning is issued, immediately replace the battery. Replace the batteries while applying the drive unit's control power.

Do not short circuit, charge, overheat, incinerate or disassemble the battery.

For after-purchase servicing of the built-in motor, only the servicing parts for MITSUBISHI encoder can be supplied. For the motor body, prepare the spare parts at the machine tool builders.

For maintenance, part replacement, and services in case of failures in the built-in motor (including the encoder), take necessary actions at the machine tool builders. For drive unit, Mitsubishi can offer the afterpurchase servicing as with the general drive unit.

(7) Disposal

Take the batteries and backlights for LCD, etc., off from the controller, drive unit and motor, and dispose of them as general industrial wastes.

Do not disassemble the unit or motor.

Dispose of the battery according to local laws.

Always return the secondary side (magnet side) of the linear servo motor to the Service Center or Service Station.

When incinerating optical communication cable, hydrogen fluoride gas or hydrogen chloride gas which is corrosive and harmful may be generated. For disposal of optical communication cable, request for specialized industrial waste disposal services that has incineration facility for disposing hydrogen fluoride gas or hydrogen chloride gas.

1.1.3 Cautions for Mounting Load (Prevention of Impact on Shaft)

[1] When using the servo motor with key way, use the screw hole at the end of the shaft to mount the pulley onto the

shaft. To install, first place the double-end stud into the shaft screw holes, contact the coupling end surface against

the washer, and press in as if tightening with a nut. When the shaft does not have a key way, use a frictional

coupling, etc.

[2] When removing the pulley, use a pulley remover, and make sure not to apply an impact on the shaft. [3] Install a protective cover on the rotary sections such as the pulley installed on the shaft to ensure safety. [4] The direction of the encoder installed on the servo motor cannot be changed.

CAUTION

Never hammer the end of the shaft during assembly.

1.1.4 Installation Direction

[1] There are no restrictions on the installation direction. Installation in any direction is possible, but as a standard the

motor is installed so that the motor power line and encoder cable cannon plugs (lead-in wires) face downward.

Installation in the standard direction is effective against dripping. Measure to prevent oil and water must be taken

when not installing in the standard direction. When the motor is not installed in the standard direction, refer to

section "Oil/Water Standards" and take the appropriate measures.

The brake plates may make a sliding sound when a servo motor with magnetic brake is installed with the shaft

facing upward, but this is not a fault.

CAUTION

1. Use a flexible coupling when connecting with a ball screw, etc., and keep the shaft core deviation to below the tolerable

2. When directly installing the gear on the motor shaft, the radial load increases as the diameter of the gear decreases. This

should be carefully considered when designing the machine.

3. When directly installing the pulley on the motor shaft, carefully consider so that the radial load (double the tension)

generated from the timing belt tension is less than the values shown in the table above.

4. In machines where thrust loads such as a worm gear are applied, carefully consider providing separate bearings, etc., on

the machine side so that loads exceeding the tolerable thrust loads are not applied to the motor.

5. Do not apply the loads exceeding the tolerable level. Failure to observe this may lead to the axis or bearing damage.

CAUTION

If the cautions in motor installation in the above table are not observed, the motor will have a broken shaft, or the bearing

will have a shorter life. Carry out design and installation adjustment so that the load on the motor shaft will be below the

tolerable loads mentioned in "Shaft Characteristics".

(1) Direct coupling - Flexible coupling

When coupling the load directly, a flexible coupling is recommended. The benefits of a flexible coupling are as below. (a) Shaft's angle deviation and core deviation can be absorbed to some extent, so adjustment in motor installation

is easier. However, in the case of single, shaft core deviation cannot be allowed, so it is required to design and adjust so that the shaft cores of the motor and ball screw align. Check the specification of the coupling to use. If the shaft core deviation exceeds the coupling's tolerable level, the motor will have a broken shaft, or the bearing will have a shorter life. Thus, in order to simplify the installation adjustment, use a double flexible coupling.

(b) Less looseness produces less vibration and less noise at the coupling part.

On the other hand, if assembling is loose, lower rigidity may be caused. When using a coupling with lower rigidity, the accuracy in centering the core doesn't have to be high, however, it is undesirable for servo. In order to fully utilize the servo's efficiency to ensure the maximum durability of the equipments, it is required to use a highly rigid coupling, and to fully align the shaft cores in the initial installation. It is also required to select the optimum flexible coupling according to the working conditions, and use it correctly according to the manufacturer's specification manual.

Servo motor

A rigid coupling has benefits such as high rigidity, and relatively lower price. However, shaft core deviation and

angle deviation of the motor shaft and ball screw are not allowed, so full attention is required in installing the rigid

coupling. Shaft core deviation is desired to be 0.01mm or less. If enough accuracy cannot be ensured, the motor

will have a broken shaft, or the bearing will have a shorter life.

Also note that the motor side ball screw bearing must be locked so that to avoid the thrust load on the motor shaft

due to expansion and contraction of the ball screw.

(3) Gear connection

Gear's accuracy and backlash amount greatly affect on the machine's

positioning accuracy and noise during operation.

Thus, according to the machine's specification, appropriately select the

accuracy and backlash amount.

In gear connection, it is required to take measures against oil to enter

the motor.

1.1.8 Oil / Water Standards

(1) The motor protective format uses the IP type, which complies with IEC Standard.

However, these Standards are short-term performance specifications. They do not guarantee continuous environmental protection characteristics. Measures such as covers, etc., must be taken if there is any possibility that oil or water will fall on the motor, and the motor will be constantly wet and permeated by water. Note that the motor's IP-type is not indicated as corrosion-resistant.

The servo motor does not have a waterproof structure.

CAUTION

1. The servo motors, including those having IP67 specifications, do not have a completely waterproof (oil-proof) structure.

Do not allow oil or water to constantly contact the motor, enter the motor, or accumulate on the motor. Oil can also enter

the motor through cutting chip accumulation, so be careful of this also.

2. Oil may enter the motor from the clearance between the cable and connector. Protect with silicon not to make the

clearance.

3. When the motor is installed facing upwards, take measures on the machine side so that gear oil, etc., does not flow onto

the motor shaft.

(Note 1) These flange sizes are recommended dimensions when the flange material is an aluminum. (Note 2) If enough flange size cannot be ensured, ensure the cooling performance by a cooling fan or operate the

motor in the state that the motor overheat alarm does not occur.

1.1.10 Cable Stress

[1] Sufficiently consider the cable clamping method so that bending stress and the stress from the cable's own weight

is not applied on the cable connection part.

[2] In applications where the servo motor moves, make sure that excessive stress is not applied on the cable.

If the encoder cable and servo motor wiring are stored in a cable bear and the servo motor moves, make sure that the cable bending part is within the range of the optional encoder cable. Fix the encoder cable and power cable enclosed with the servo motor.

[3] Make sure that the cable sheathes will not be cut by sharp cutting chips, worn or stepped on by workers or vehicles.

The bending life of the encoder cable is as shown below. Regard this with a slight allowance. If the servo motor/spindle motor is installed on a machine that moves, make the bending radius as large as possible.

motor failures such as the shaft distortion or bearing/encoder damage.

4. Never touch the motor during operations or right after the stop. Install a cover, etc., on the rotary sections.

5. Do not apply a load exceeding the tolerable load onto the servo motor shaft. The shaft could break. Failure to observe

this could lead to injuries.

6. Do not connect or disconnect any of the connectors while the power is ON.

7. When coupling the motor directly with the spindle, perform the adequate centering and parallel correcting with the axis to

be coupled. The vibration of the motor should be 4.9m/s

Locations where motor vibration is measured

Measuring device

Coupling

Cushioning mat

When a spindle motor is driven at a high speed with unbalance generated on the rotor, the whirling load is generated and the load to the motor's internal bearings is increased. Thus abnormal vibration, and/or damages known as fretting or flaking occurs to the bearings, which may result in shorter bearing life. Therefore, it is important to balance the rotation so that great vibration does not occur during rotation at high speed. When balancing the spindle motor, perform to the entire rotational objects including the gear, pulley, coupling, etc. that are attached directly on the motor shaft. Provide a balancing mechanism including screw holes on the fittings while measuring the vibration so that the vibration is suppressed to the specified level or lower during high speed rotation.

(1) Fittings for the motor shaft

When you select fittings for the motor shaft, such as a gear, pulley, and coupling, choose those that meet the motor specifications (shaft diameter, rotation speed and output torque).

CAUTION

1. We consider key-less shaft as standard in order to simplify balancing procedure of such as gear, pulley, and coupling.

We recommend you to choose a gear, pulley and coupling that have a fully symmetric shape, and arrange screw holes

on their end faces at short and equal intervals in the circumferential direction.

2. Use a fastener such as a shaft lock element to fix those fittings to the motor shaft.

3. When you attach fittings to the motor shaft, be careful not to apply excessive impact by striking with a hammer, etc. This

may cause the shaft distortion and bearing damage.

4. When using screws for balancing, apply thread locker on the screws after balancing.

(2) How to measure the unbalance

After attaching the fittings such as gear, pulley, and coupling, carry out no-load operation, and use an accelerometer or vibrometer compatible with frequency analysis to confirm the vibration on the points as illustrated below (on the brackets where the bearings are stored). Make sure to place the motor on a cushioning mat to avoid vibration to the spindle from external sources during measurement. Reaction torque is generated when accelerating/decelerating the motor, so securely fix the motor with a belt, etc. to avoid rolling during measurement.

1. Make sure to place the motor on a cushioning mat to avoid resonance with surrounding devices during measurement.

2. Always secure the spindle motor body with a belt, etc. because it may roll due to the reaction torque generated during

CAUTION

acceleration/deceleration operation.

(3) How to balance the rotation

Find out the rotation speed at which the vibration reaches the maximum, within the actual rotation speed range of

the spindle motor. Run the motor at the speed found above and perform balancing to minimize the vibration. When

balancing is decided, measure the vibration at different rotation speeds and make a further fine adjustment so that

the vibration acceleration generated is always 0.5G (4.9m/s

) or less.

(The vibration acceleration of 0.5G is about 4.7μm when expressed in terms of the amplitude at the rotation speed

of 10,000r/min. The higher the rotation speed is, the smaller the corresponding amplitude becomes.)

[1] We recommend you to adjust the dynamic balance (field balance) before fastening a belt. [2] The position deviation in the axial direction between the motor pulley and spindle side pulley should be as small as

possible and perform parallel correcting carefully.

[3] If the selection or tension of belt is incorrect, an excessive force is applied to the shaft end and bearings, which may

result in shorter life or damages.

[4] When the load by the belt exceeds the tolerable radial load of the motor, reselect the motor or belt/pulley. [5] Use an appropriate tension gauge to measure a belt tension.

1.2.6 Installation of Rotary Joint and Coolant Joint (Hollow Shaft Specifications)

Attach the fittings such as pulley, gear, coupling, and coolant joint to the motor output shaft when connecting a spindle motor to a spindle. The incorrect selection of fittings or inadequate installation accuracy can generate abnormal vibration or noise at the coupling. It can also shorten the motor or bearing life, and can damage them (fretting or flaking). Contact the manufacturer with any questions regarding the fittings mentioned above.

< Reference > Bearing damage

Fretting: Fretting occurs when contact surfaces produce abrasive red-rust powders, which wear contact surfaces and make small dimples on them. If fretting occurs on the raceway surfaces, dimples are made in the rolling element pitch. Adding vibration load on the contact parts generates a small amplitude oscillation, which forces out lubrication from those parts until there is no lubrication, resulting in significant wear.

Flaking: Flaking occurs when small pieces of bearing raceway surfaces peel off due to rotation fatigue. It may occur in an early stage due to an excessive load, handling fault, inadequate accuracy of shaft or housing, or a load application by incorrect installation.

(a) Installation

Rotary joints are used to supply/exhaust high pressure fluid or liquid which is equal to or lower than the atmospheric pressure from the fixed pipe to rotary parts of each mechanical device with no leakage. When attaching a separate external-support type rotary joint to the shaft rear end, structure the rotary joint so that cutting fluid (drain), which is generated when switching ON/OFF the coolant pressure, does not enter inside of the motor. (i) Provide notches or drain so that the cutting fluid (drain) that has entered the rotary joint housing will not

accumulate. (ii) A rotary joint is a consumable part. Check and replace regularly. (iii) Many notches must be provided on the housing as a large amount of cutting fluid may leak if the rotary

joint is damaged. (iv) If the motor is used vertically facing down, enhance the drain using parts such as an air purge.

(b) Recommended models of rotary joint

The tables below show the recommended models manufactured by Deublin and Rix. The target models are designed to have these rotary joints attached to the shaft rear end. Contact the manufacturer for details of rotary joint.

When spindle through coolant is used, the thrust load works between the spindle and the motor at the position A, and between the motor and the rotary joint at the position B in the figure below. Setting the diameter of the pressured area of the coolant joint attached to the end of the motor shaft appropriately makes the thrust load at the position B slightly larger than at the position A, which is effective for coolant pump pulsation.

Install the coolant joint to the motor shaft end so that it stops at the shaft edge. Stopping the coolant joint at the edge of the inner diameter or at the screw bottom may generate an excessive radial runout, which may generate abnormal noise or vibration.

(3) Coupling

(a) Caution when selecting coupling

Always use a flexible coupling for coupling the spindle and the motor. The flexible coupling is flexible enough to absorb a certain level of radial runout and parallel offset. The flexible coupling has tolerable values for three degrees of freedom (parallel offset, angular misalignment, and axial movement), which realizes a low-vibration and low-noise coupling up to high-speed rotation.

- Tolerable values of parallel offset and angular misalignment:

Absorbs minor misalignments or declinations that were not resolved during alignment.

- Tolerable value of axial movement:

Absorbs elongation of the spindle and motor shaft due to thermal expansion.

(These tolerable values are the standard values for which the coupling does not break. They are not the

standard values for which the load is not applied to the spindle or the motor bearing. Thus, in order to

rotate up to high-speed with low-vibration and low-noise, the spindle and the motor shaft must be

aligned.)

(b) Recommended model of coupling

The table below shows the recommended models manufactured by Miki Pulley and Eagle Industry.

Company Product name (or Series) Contact

Miki Pulley SERVO FLEX https://www.mikipulley.co.jp/EN/

Eagle Industry Diaphragm https://www.ekkeagle.com/en/

(Note) The diaphragm coupling in the table above absorbs the misalignment of the rotary axis with the

elastic deformation of the extremely thin metal diaphragm. In addition, there are the features as light weight, no lubrication and high torsional stiffness, so it is recommended as a coupling of a highspeed motor.

IB-1501229-F

MDS-E/EH Series Instruction Manual

1 Installation

The following describes how to install a coupling using a product by Miki Pulley. Contact the manufacturer for details of cautions and confirmation.

(i) Make sure that the pressure bolts of the coupling are loosened, and remove rust, dirt, and grease, etc.

from the shaft and the inner diameter part of the coupling. (Grease should be wiped away with a cloth, etc., or by degreasing as required.)

(ii) When inserting the coupling into the motor shaft, make sure that no excessive force such as

compression, tension, etc. is applied to the element.

(iii) Make sure that the insertion length of the coupling into the motor shaft is kept in the position where the

target shaft is in contact with the entire length of the flange of the coupling (LF dimension) as illustrated below. (For the variation of models and the length of LF of each model, contact the manufacturer.)

(iv) Tighten the pressure bolts lightly diagonally by using a bore for rotation prevention. (v) Apply a dial gauge to the flange edge or outer diameter of the motor side. While rotating the motor shaft

lightly by hand, perform hammer adjustment on the flange periphery and edge so that the radial runout will be reduced to as close as zero.

(vi) While performing hammer adjustment, tighten the pressure bolts in sequence. Finally, use a calibrated

torque wrench and tighten all the pressure bolts at the appropriate tightening torque as shown in the table below. Also, refer to the following drawing for the sequence to tighten the pressure bolts, and make sure that the bolts are tightened equally.

Pressure

bolt size

M6 M8

(vii) Confirm that the pressure bolts of the motor shaft side are tightened to the specified torque and the value

of radial runout is small enough.

(viii) Install the motor mounted with coupling to the machine. At this time, adjust the motor mounting position

(inlay) while inserting the coupling into the spindle or feed screw. Check that there is no deformation of the plate spring. Also check that the insertion length of the mating shaft is kept in the position where the target shaft is in contact with the entire length of the flange of the coupling (LF dimension).

(ix) The space between flange hubs (S) must be within the permissible error of the axial movement for the

standard value. Note that the allowable value assumes that parallel offset and angular misalignment are 0

(zero). Adjust them to achieve values as small as possible. (For the standard value of the S dimension of

each model, contact the manufacturer.)

(x) As in the sequence for the pressure bolts on the motor shaft side, sequentially tighten the pressure bolts

on the spindle side or the feed screw side. Finally, tighten the bolts at the appropriate tightening torque. (xi) As a countermeasure against initial loosening of the pressure bolts, it is recommended to additionally

tighten the bolts with the appropriate tightening torque after a certain period of operation.

CAUTION

1. Select a coupling that the thrust load will not work on the motor shaft due to a rise of temperature, during cutting, or due

to the coolant pressure, etc.

2. Do not hit the coupling with a tool such as a hammer when installing it to the motor shaft so that the impact load will not

be applied to the bearing.

3. Do not rely on the flexibility of the coupling only. Make sure to perform alignment also. If the motor rotates with a parallel

offset, the bearing may be damaged by fretting wear etc. in a short amount of time.

4. When the motor shaft and the spindle are joined by a coupling, the motor shaft may stay pushed inside the motor.

Confirm that the distance from the surface to install the housing to support the rotary joint to the rear end of the flinger is

kept the same before and after inserting the coupling.

1.2.7 Ambient Environment

If you continue to use the spindle motor with dirt such as oil mist and dust adhered, its cooling performance degrades and the motor is unable to fully exercise its performance, which may cause the spindle motor overheat alarm. In some cases this may result in damage to the bearing or cooling fan. Use a filter, etc. to protect the motor from oil mist and dust.

1.2.8 Installation of Spindle Motor

Make sure that the spindle motor is installed so that the motor shaft points from downward to 90° as shown below. When installing upward more than 90°, contact your Mitsubishi Electric dealer.

CAUTION

1. Rubber packing for waterproof is attached on the inner surface of the top cover of terminal block, and on the fan lead.

After checking that the packing is installed, install the top cover so that no foreign objects are stuck in between.

2. When installing a motor on a flange, chamfer(C1) the part of flange that touches inside low part of the motor.

To yield good cooling performance, provide a space of at least 30mm between the cooling fan and wall. If the motor is covered by a structure and the air is not exchanged, its cooling performance degrades and the motor is unable to fully exercise its performance, which may cause the spindle motor overheat alarm. Do not use the spindle motor in an enclosed space with little ventilation.

terminal.

3.To keep the insulation distance, always cover crimp terminals with insulation tubes when connecting crimp terminals at

the end of the power line.

(2) Connection of conduit connector

When installing a connector to a terminal box, select a water proof connector with rubber packing and prevent conductive foreign matter and other combustible foreign matter from entering through the wiring hole on the terminal box. Use a smaller nut than the following size to fix the connector on the terminal box. For the wiring hole diameter, refer to "DRIVE SYSTEM DATA BOOK (IB-1501252)". Prepare a bushing, nut, and O-ring when using a connector smaller than the wiring hole on the terminal box.

Treat the cabinet with the following items. (1) Make sure that the cable inlet is dust and oil proof by using packing, etc. (2) Make sure that the external air does not enter inside by using head radiating holes, etc. (3) Close all clearances of the cabinet. (4) Securely install door packing. (5) If there is a rear cover, always apply packing. (6) Oil will tend to accumulate on the top. Take special measures such as oil-proofing to the top so that oil does not

enter the cabinet from the screw holds.

(7) After installing each unit, avoid machining in the periphery. If cutting chips, etc., stick onto the electronic parts,

trouble may occur.

(8) When using the unit in an area with toxic gases or high levels of dust, protect the unit with air purging (system to

blow clean air so that the panel's inner pressure is higher than the outer pressure).

(1) Part configuration

The encoder is configured of a sensor and detection gear. The sensor and detection gear must be used in the designated combination. These are precision parts, and require care when handling. Do not apply an excessive force on the sensor's detection surface, as this could result in faults. Do not pull and apply a load on the lead wires. Make sure that foreign matters (iron chips, etc.) do not get on the sensor's detection surface or detection gears. If any foreign matter should get on these parts, carefully remove while taking care not to damage the parts. When handling the detection gears, take care not to damage or deform the teeth.

Spindle side PLG serial output encoder TS5690 Series

(2) Installing the detection gears

[1] Install the detection gears so that the first gear's teeth side (Z phase) face the sensor's lead side. [2] The detection gears and shaft or sleeve should be fixed with shrink fitting. Refer to the following table for the

shrink fitting values. The detection gears should be heated evenly between 120 and 150°C using an electric furnace, etc.

Inner diameter (mm) Shrink fitting (mm) Inner diameter (mm) Shrink fitting (mm)

Φ40 0.020 to 0.040 Φ140 0.050 to 0.085 Φ70 0.030 to 0.055 Φ160 0.060 to 0.090 Φ80 0.030 to 0.055 Φ215 0.080 to 0.110

Guideline for detection gear shrink fitting values

Φ125 0.050 to 0.085

[3] Keep the run-out of the outer diameter, when the detection gears are installed on the shaft, to 0.02mm or less. [4] To remove a detection gear fixed with shrink fitting, use the screw holes opened in the axial direction for pulling

(two M5 screw holes or two M8 screw holes), or push the end with a jig. Carry out this work carefully. Applying excessive force when pulling out the gears could cause the inner diameter of the detection gears to deform.

[5] Before reusing detection gears which have been removed, always measure the inner diameter dimensions,

and carefully check that the inner diameter is not deformed, and that the sufficient tightening amount can be secured. Do not reuse the detection gears if the inner diameter is deformed, or if any abnormality such as damage to the teeth is found.

[3] Fix the sensor with its R section butted against the notched fitting

section so that the position relation between the detection gear and sensor is kept constant. This ensures favorable accuracy of the sensor installation.

[4] Keep the deviation of the sensor center and outer diameter center of

the detection gear to ±0.25mm or less. If the center deviation cannot be directly measured, set so that the dimension from the sensor installing surface to the outer diameter edge of the detection gears is

19.0±0.25mm. (Some detection gears have thickness at the inner diameter section.)

[5] Make sure that force is not constantly applied on the sensor's lead

(4) Installation accuracy diagnosis for spindle side PLG encoder

CAUTION

Do not operate the spindle before performing this installation accuracy diagnosis.

If operated with an improperly installed spindle side PLG encoder, the spindle motor may rotate at high speed.

Always perform this diagnosis before normal operation.

[1] Outline

In this section, check if the installation polarity of spindle side PLG encoder corresponds to the parameter setting, and the gap between the gear and the sensor is appropriate. In a full-closed loop control where the encoder is also installed on the spindle side, it is controlled based on the feedback of the spindle side encoder during the speed command operation (S command). Do not command a normal spindle operation before confirming the installation accuracy of the spindle side encoder.Spindle side PLG encoders (TS5690 Series) have the specified gap from the gear by installing the sensor section on the machine-notched fitting section. Whether a signal is detected correctly or not can be confirmed using the servo diagnosis screen on NC while rotating the spindle motor in an open loop control.

[2] Confirmation of encoder installation polarity

Open the drive monitor/spindle unit on the NC Diagnosis screen, and display "Machine position", "Motor end FB" and "FB error". Confirm that "Machine position" and "Motor end FB" are counted on the same polarity, and that "FB error" is not cumulated while rotating the spindle by hand. When the polarity of "Machine position" and "Motor end FB" is different and "FB error" is cumulated, change the setting of #13017/bit4 (SP017/bit4). Set the spindle parameter so that the spindle system is in a full-closed loop control during this confirmation.

- #13019 (SP019) Set the encoder resolution of spindle side PLG encoder correctly

- #13031 (SP031) Set to full closed loop control (6200)

[3] Confirmation of encoder installation accuracy

Whether the gap between the sensor section and the gear is ensured correctly or not can be confirmed using the servo diagnosis screen, [PLG diagn] on NC while rotating the spindle motor in an open loop control. Confirm it according to the following procedures.

1) Set the spindle parameter #13018/bit1 (SP018/bit1) to 1 to enable an open loop control.

2) Turn the NC and drive unit power OFF and disconnect the motor side encoder cable only. After that, turn the power ON again.

3) Rotate the spindle by inputting 100r/min command. Although this is the same as normal S command operation, neither the spindle side encoder feed back or the motor side encoder feed back is used for the motor control on the spindle drive unit since the open loop control is set with the spindle parameter.

4) Switch to the [Servo diagn] menu on the NC maintenance screen and change from [Spindle unit] to [PLG diagn]. When all the diagnosis signal bits are constantly at "0", the installation of PLG encoder is normal. When the diagnosis signal bit is "1", the result of diagnosis is abnormal. Perform troubleshooting following "[4] Diagnosis and remedy" by reference to the error details and main cause.

5) Set the spindle parameter #13018/bit1 (SP018/bit1) to 0 again and finish the open loop control after stopping the spindle with stop command.

6) Turn the NC and spindle drive unit power OFF, and reconnect the motor side encoder cable as it was.

CAUTION

The spindle PLG diagnosis is only performed during the open loop control operation.Diagnosis screen is displayed even

during the normal operation, however, the error detection ("1" display) will not be performed.

1.6 Noise Measures

Noise includes "propagation noise" generated from the power supply or relay, etc., and propagated along a cable causing the power supply unit or drive unit to malfunction, and "radiated noise" propagated through air from a peripheral device, etc., and causing the power supply unit or drive unit to malfunction. Always implement these noise measures to prevent the peripheral devices and unit from malfunctioning. The measures differ according to the noise propagation path, so refer to the following explanation and take appropriate measures.

(1) General noise measures

(a) Avoid laying the drive unit's power line and signal wire in a parallel or bundled state. Always separate these

wires. Use a twisted pair shielded wire for the encoder cable and signal wires such as the communication

cable connected with the NC unit, and accurately ground the devices. (d) Ground the shield of the servo encoder's cable with a cable clamp. (c) Accurately ground the AC reactor.

(2) Propagation noise measures

Take the following measures when noise generating devices are installed and the power supply unit or drive unit could malfunction. (a) Install a surge killer on devices (magnetic contacts, relays, etc.) which generate high levels of noise. (b) Install a power line filter in the stage before the power supply unit. (c) Install a ferrite core on the signal wire. (d) Ground the shield of the servo encoder's cable with a cable clamp. (e) Wire the spindle PLG encoder cable away from other wires.

(3) Measures against radiated noise

The types of propagation paths of the noise and the noise measures for each propagation path are shown below.

Noise propagation path Measures

When devices such as instrument, receiver or sensor, which handle minute signals and are easily affected by noise, or the signal wire of these devices, are stored in the same panel as the drive units and the wiring is close, the device could malfunction due to airborne propagation of the noise. In this case, take the following measures. (a) Install devices easily affected as far away from the drive units as possible.

[1] [2] [3]

(b) Lay devices easily affected as far away from the signal wire of the drive unit as possible. (c) Avoid laying the signal wire and power line in a parallel or bundled state. (d) Insert a line noise filter on the input/output wire or a radio filter on the input to suppress the noise radiated from the wires. (e) Use a shield wire for the signal wire and power line, or place in separate metal ducts.

If the signal wire is laid in parallel to the power line, or if it is bundled with the power line, the noise could be propagated to the signal wire and cause malfunction because of the magnetic induction noise or static induction noise. In this case, take the following measures.

[4] [5] [6]

(a) Install devices easily affected as far away from the drive unit as possible. (b) Lay devices easily affected as far away from the signal wire of the drive unit as possible. (c) Avoid laying the signal wire and power line in a parallel or bundled state. (d) Use a shield wire for the signal wire and power line, or place in separate metal ducts.

If the power supply for the peripheral devices is connected to the power supply in the same system as the drive units, the noise generated from the power supply unit could

[7]

back flow over the power line and cause the devices to malfunction. In this case, take the following measures. (a) Install a radio filter on the power supply unit's power line. (b) Install a power filter on the power supply unit's power line.

If a closed loop is created by the peripheral device and drive unit's grounding wire, a

[8]

leakage current could flow and cause the device to malfunction. In this case, change the device grounding methods and the grounding place.

2.3 NC and Drive Unit Connection

2.3.1 Connection of Optical Communication Cables

Connect the optical communication cables from the NC to the each drive unit so that they run in a straight line from the NC to the drive unit that is a final axis. And up to 16 axes can be connected per system. Note that the number of connected axes is limited by the NC.

CAUTION

1. Connect the NC and the drive units by the optical communication cables. The distance between the NC and the final

drive unit must be within 30m and the specified bending radius (for wiring inside panel: 25mm, and for wiring outside

panel: 50mm) or more.

2. For the main circuit wiring of the drive unit and power supply unit, the drive unit of 200V series is to be wired with MDS-

D2-CV, and the drive unit of 400V series is to be wired with MDS-EH-CV.

POINT

Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to section "Setting the rotary switch".) The axis

No. has no relation to the order for connecting to the NC.

(1) When using one power supply unit

Connect the largest-capacity spindle drive unit to the final axis of the NC communication bus in order to control the power supply unit. The spindle drive unit must be installed adjacent to the power supply unit. In the system with servo only, a servo drive unit for controlling unbalance axis must be installed in the same manner in the same way.
