WARNING

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 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.

Wait at least 15 minutes after turning the power OFF before starting wiring or inspections. Failure to observe this could lead to electric shocks.

Ground the unit and motor with Class C (former class 3) grounding or higher.

Wiring 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.

2. Injury prevention

The linear servomotor uses a powerful magnet on the secondary side, and could adversely affect pacemakers, etc.

During installation and operation of the machine, do not place portable items that could malfunction or fail due to the influence of the linear servomotor's magnetic force.

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

CAUTION

1. Fire prevention

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

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

Provide a sequence that shut off the power at the regenerative resistor error signal-ON when using the regenerative resistor. 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.

CAUTION

2. Injury prevention

Do not apply a voltage other than that specified in Instruction 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.

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

3. Various precautions

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 motor when it is installed on the machine.

Do not stack the products above the tolerable number.

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.

Follow this Instruction 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.

Note 1) -15°C to 55°C for linear servomotor.

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

Always install the servomotor 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 servomotor shaft end, do not apply an impact by hammering, etc. The detector could be damaged.

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

Store the motor in the package box.

When inserting the shaft into the built-in IPM 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) when installing the linear servomotor.

Always provide a mechanical stopper on the end of the linear servomotor'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 or Service Station.

CAUTION

(2) Wiring

Correctly and securely perform the wiring. Failure to do so could lead to runaway 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.

Always install an AC reactor for each power supply unit.

Always install an appropriate breaker for each power supply unit. Breakers cannot be shared by several units.

Direct application of a commercial power supply to the motor could cause burning. Always connect the motor to the drive unit's output terminals (U, V, W).

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	Drive unit	Diode reverse orientation
connect to a DC relay for the control output
signals to suppress a surge. Connecting it	COM
backwards could cause the drive unit to	(24VDC)
malfunction so that signals are not output, and

inoperable.	signal				RA

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 connection 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.

CAUTION

(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 as the operation could become unstable.

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

If the axis is unbalanced due to gravity, etc., balance the axis using a counterbalance, etc.

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

(4) Usage methods

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.

Unqualified persons must not disassemble or repair the unit. Never make modifications.

Reduce magnetic damage by installing a noise filter. The electronic devices used near the unit could be affected by 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) assembled into the servomotor are for holding, and must not be used for normal braking. Do not apply the brakes in the servo ON state. Doing so will lead to a drop in the brake life. Always turn the servo OFF before applying the brakes.

There may be cases when holding is not possible due to the magnetic brake's life or the machine construction (when ball screw and servomotor are coupled via a timing belt, etc.). 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 the separate specifications manual for the power (input voltage, input frequency, tolerable sudden power failure time, etc.).

CAUTION

(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.

Shut off with the servomotor brake control output.

Servomotor MBR

Magnetic brake

Shut off with NC brake control PLC output.

EMG

24VDC

Always turn the input power OFF when an alarm occurs.

Never go near the machine after restoring the power after a power failure, as the machine could start suddenly. (Design the machine so that personal safety can be ensured even if the machine starts suddenly.)

(6) Maintenance, inspection and part replacement

Always backup the programs and parameters in the CNC device 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 or Service Station for 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 replace the battery.

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

The heat radiating fin used in the 37kW and smaller unit contains substitute Freon as the refrigerant.

Take care not to damage the heat radiating fin during maintenance and replacement work.

(7) Disposal

Do not dispose of this unit as general industrial waste. The 37kW and smaller unit with heat radiating fin protruding from the back of the unit contains substitute Freon. Do not dispose of this type of unit as general industrial waste. Always return to the Service Center or Service Station.

Do not disassemble the unit or motor.

Dispose of the battery according to local laws.

Heat radiating fin

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

CAUTION

(8) Transportation

The unit and motor are precision parts and must be handled carefully.

According to a United Nations Advisory, the battery unit and battery must be transported according to the rules set forth by the International Civil Aviation Organization (ICAO), International Air Transportation Association (IATA), International Maritime Organization (IMO), and United States Department of Transportation (DOT), etc.

					2. Wiring and Connection
1.					Wiring work must be done by a qualified technician.
2.					Wait at least 15 minutes after turning the power OFF and check the voltage
					with a tester, etc., before starting wiring. Failure to observe this could lead to
			DANGER
					electric shocks.

3.Securely ground the drive units and servo/spindle motor with Class 3 grounding or higher.

4.Wire the drive units and servo/spindle motor after installation. Failure to observe this could lead to electric shocks.

5.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.

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

1.Correctly and securely perform the wiring. Failure to do so could lead to runaway of the servo/spindle motor.

2.Do not mistake the terminal connections.

Failure to observe this item could lead to ruptures or damage, etc.

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

4.Do not mistake the direction of the diodes for the surge absorption installed on the DC relay for the motor brake and contactor (magnetic contactor) control. The signal might not be output when a failure occurs.

CAUTION

Drive unit

COM (24VDC)

Control output signal

RA

5.Electronic devices used near the drive units may receive magnetic obstruction. Reduce the effect of magnetic obstacles by installing a noise filter, etc.

6.Do not install a phase advancing capacitor, surge absorber or radio noise filter on the power line (U, V, W) of the servo/spindle motor.

7.Do not modify this unit.

8.The half-pitch connector (CN1A, etc.) on the front of the drive units have the same shape. If the connectors are connected incorrectly, faults could occur.

Make sure that the connection is correct.

9.When grounding the motor, connect to the protective grounding terminal on the drive units, and ground from the other protective grounding terminal.

(Use one-point grounding)

Do not separately ground the connected motor and drive unit as noise could be generated.

1.Always use one AC reactor per power supply unit. Failure to observe this could lead to unit damage.

	CAUTION	2. When sharing a breaker for several power supply units, of a short-circuit
		fault occurs in a small capacity unit, the breaker could trip. This can be
		hazardous, so do not share the breaker.

3. Be sure to use the breaker of proper capacity for each Power Supply Unit.

2-2-3 How to use the control circuit terminal block (MDS-CH-SP-750)

The control power for the 75kW spindle unit is not connected to the terminal block, so wire according to the following instructions.

<1> Treatment of wire end	Length to peel

Single wire: Peel the wire sheath, and use the wire.

(Wire size: 0.25 to 2.5 mm2)

Approx. 10mm

Stranded wire: Peel the wire sheath, and then twist the core wires. Take care to prevent short circuits with the

neighboring poles due to the fine strands of the core wires. Solder plating onto the core wire section could cause a contact defect and must be avoided. (Wire size: 0.25 to 2.5 mm2)

Use a bar terminal and bundle the strands. (Made by Phoenix contact)

<2> Connection method

Insert the core wire section of the wire into the opening, and tighten with a screwdriver so that the wire does not come out. (Tightening torque: 0.5 to 0.6 N•m) When inserting the wire into the opening, make sure that the terminal screw is sufficiently loose. When using a wire that is 1.5 mm2 or less, two wires can be inserted into one opening.
