1. Electric shock prevention

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. Fa ilure 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 following the standards set forth by each country. Wiring, maintenance and inspection work must be done by a qualified technician. Wire the servo drive unit and servomotor 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. After assembling the built-in IPM 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

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 servomotor, direct-drive motor and built-in IPM spindl e motor uses permanent ma gnets in the rotor, so observe the following precautions . (1)Handling

• The linear servomotor, direct-drive motor and built-in IPM 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 finger s 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.

(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 servomotor.

1. Fire prevention

CAUTION

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 caus e bu rn s or part dam a ge .

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

3. Various precautions

CAUTION

Observe the following precautions. Incorrect handling of the unit could lead to faults, injuries and electric

shocks, etc.

(1) Transportation and installation

Correctly transport the product according to its weight. Use the motor's hanging bolts only when transporting the motor. Do not transport the machine when the

motor is installed on the machine. Do not stack the products above the tolerable number. Follow this manual and install the unit or motor in a place where the weight can be borne. Do not get on top of or place heavy objects on the unit.

Do not hold the cables, axis or detector when transporting the motor.

Do not hold the connected wires or cables when transporting the units. Do not hold the front cover when transporting the unit. The unit could drop. Always observe the installation directions of the units or motors. Secure the specified distance between the units and control panel, or between the servo drive unit and

other devices. Do not install or run a unit or motor that is damaged or missing parts. Do not block the intake or exhaust ports of the motor provided with a cooling fan. Do not let foreign objects enter the units or motors. In particular, if conductive objects such as screws or

metal chips, etc., or combustible materials such as oil enter, rupture or breakage could occur. Provide adequate protection using a material such as connector for conduit to prevent screws, metallic

detritus, water and other conductive matter or oil and other combustible matter from entering the motor through the power line lead-out port.

The units, motors and detectors are precision devices, so do not drop them or apply strong impacts to them.

COM (24VDC)

Servodrive unit

Control output signal

Always connect the motor to the drive unit's output terminals (U, V, W). Do not directly connect a commercial power supply to the servomotor. 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. Always separate the signals wires from the drive wire and 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 op er ation . Failur e to do so cou l d 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 models before starting trial operation.

The linear servomotor does not have a stopping device such as magnetic brakes. Install a stopping device on the machine side.

(4) Usage methods

CAUTION

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, ab nor ma l 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 combinatio n. Failur e to do so could lead to fires or trouble.

The brake (magnetic brake) of the servomotor are for ho ldin g, and m ust not b e used fo r nor mal br aking . There may be cases when holding is not possible due to the magnetic brake's life, the machine

construction (when ball screw and servomotor 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 an d 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, tolerable sudden power failure time, 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.

(5) Troubleshooting

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

Use a double circuit configuration that allows the operation circuit for the magnetic brakes to be operated even by the external emergency stop signal.

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.

(6) Maintenance, inspection and part replacement

Always backup the programs and parameters be fo re star tin g ma in te na nc e or insp ect ion s. 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 delayer for repairs or part replacement.

Do not perform a megger test (insulation resistance measurement) during inspections. If the battery low warning is issued, back up the machining programs, tool data and parameters with an

input/output unit, and then rep l ac e th e ba ttery. Do not short circuit, charge, overheat, incinerate or disassemble the battery. For after-purchase servicing of the built-in motor (including the detector), supplies of servicing parts and

repairs can only be offered. For maintenance, part replacement, and services in case of failures in the built-in motor (including the

detector), take necessary actions at your end. For spindle drive unit, Mitsubishi can offer the afterpurchase servicing as with the general spindle drive unit.

When a failure has occurred in the built-in motor (including the detector), some period of time can be required to supply the servicing parts or repair. Prepare the spare parts a t your end whenever possible.

(7) Disposal

Take the batteries and backlights for LCD, etc., off from the controller, drive unit an d 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 servomotor 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.

1-1-4 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 detector 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 "1-1-8 Oil/water standards" and take the appropriate

measures.

The brake plates may make a sliding sound when a servomotor with magnetic brake is installed with the

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

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.

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 "1-1-5 Shaft characteristics".

(1) Direct coupling - Flexible coupling

When coupling the load directly, a flexible coupling is recommended. The benefits of a flexible coup ling are as below. (a) Shaft's angle deviation and core deviation can be absorb ed to some ex tent, so a djustment 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 cor e doesn't ha ve to be h igh, however, it is un desirable 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.

0.01mm or less

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. In addition, note that a rigid coupling is not acceptable for HF-KP Series servo motors.

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.

[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.

[2] With the sensor installation seat's R section butted against

the notched fitting section, fix the sensor installation seat with a mounting screw (M5 x 0.8 screws). A locking agent should be applied on the mounting screw before it is tightened.

[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 22.5±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 wires.

To install the sensor section, the notched fitting section on the machine side must have the specified

PLG detects the speed and position by the rotation of the ge ar installed at the motor end or spindle end. Adjustment-free PLG can be used without adjusting the waveform after installing the sensor section (TS5690 Series) on the machined notched fitting section. With this function, whether the PLG installation position is OK or not can be judged using the D/A output of the spindle drive unit while rotating the spindle in an open loop. For an IPM spindle motor, the waveform should be measured while rotating the spindle by hand because an open loop operation cannot be carried out.

Make sure that the motor can be rotated freely in the unloaded state without being locked.

CAUTION

Installation error judgment of the adjustment-free PLG can be checked using the D/A output of the spindle drive unit. The setting numbers of D/A output are shown below. For the output waveform, 2.5V represents a normal state and +1V or -1V of the normal state represents an abnormal state. *Set the D/A output numbers to the spindle parameters "#13125(SP125)" and "#13126(SP126)". Because the D/A output of the drive unit is 2ch, perform the check for both at the motor e nd and spindle end in full closed mode.

The gap is too small

The result of the quality judgement for the gap of the motor end PLG is output. When the gap is good, =2.5V is output. When the gap is excessive, =2.5+1V is output and when the gap is too small, =2.5-1V is output. The result of the quality judgement for the installed position of the motor end PLG is output. When the sensor installation is good, =2.5V is output. When sensor installation is incorrect (such as a center deviation between a sensor and gear, and Z-phase error), =2.5+1V is output. The result of the quality judgement for the gap of the spindle end PLG is output. The output procedure is the same as that of motor end PLG. The result of the quality judgement for the installed position of the spindle end PLG is output. The output procedure is the same as that of motor end PLG.

The gap is good when the waveform is constantly at

when the gap is not good

when all results of the diagnosis are not good

When the D/A output parameter "#13125(SP125)" is set to 120(=D/A output of ch1), and "#13126(SP126)" is set to 121(=D/A output of ch2), the check is performed at the motor end detector.

POINT

When the D/A output of ch1 is 2.5V and ch2 is 3.5V(=2.5+1V), for example, the gap is normal, however, the center deviation (offset) between a sensor and gear occurs, so check again after the sensor installed position is finely adjusted. Adjust until the two D/A outputs finally become 2.5V during spindle rotation.

When the sensor installed position is finely adjusted, adjust after the power of the drive unit is turned OFF.

1-6 Noise measures

Noise includes "propagation noise" gen erated from the relay, etc., and p ropagated along a cable causing the drive unit to malfunction, and "radiated noise" propagated through air from a periph eral device, etc., and causing the power supply unit or drive unit to malfunction. Always implement these noise measures to prevent the peripheral devices an d 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 detector cable and sign al wires such

as the communication cable connected with the NC unit, and accurately ground the devices. (b) Use one-point grounding for the drive unit and motor. (c) Accurately ground the AC reactor.

(2) Propagation noise measures

Take the following measures when noise generating devices are installed and the 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 drive unit. (c) Install a ferrite core on the signal wire. (d) Ground the shield of the servo detector's cable with a cable clamp. (e) Wire the spindle PLG detector 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 generated from drive unit

Airborne propagation noise

Magnetic induction noise

Static induction noise

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]

[4] [5] [6]

[7]

[8]

(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. (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 drive unit in the same system as the drive units, the noise generated from the power supply unit could 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 drive unit's power line. (b) Install a power filter on the drive unit's power line. If a closed loop is created by the peripheral device and drive unit's grounding wire, a leakage current could flow and cause the device to malfunction. In this case, change the device grounding methods and the grounding place.

1. Be careful when selecting the installation location. Choose a location where foreign matter (cutting chips, cutting oil, etc.) does not adhere to the external regenerative resistor unit terminal. A shortcircuit between the P and C terminals could lead to drive unit damage.

2. The regenerative resistor generates heat of approximately 100 degrees (or higher, depending on the installation conditions). Give sufficient consideration to heat dissipation and installation position.

- Use flame resisting wire.

- Make sure the wires do not contact the regenerative resistor unit.

Always use twisted pair cable to connect to the drive unit, and keep the length of the wiring to 5m or less.
