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, maintenance or inspections. Failure to observe this could lead to electric shocks.

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

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.

CAUTION

1. Fire prevention

Install the servo drive units, servomotors 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 servo drive unit side if the servo drive unit fails. 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.

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.

The servo drive unit's fins, regenerative resistor and servomotor, etc., may reach high temperatures while the power is ON, and may remain hot for some time after the power is turned OFF. Touching these parts could result in burns.

CAUTION

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 servomotor's hanging bolts only when transporting the servomotor. Do not transport the servomotor 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 servomotor.

Do not hold the connected wires or cables when transporting the servo drive units.

Do not hold the front cover when transporting the servo drive units. The unit could drop.

Follow this Instruction Manual and install in a place where the weight can be borne.

Do not get on top of or place heavy objects on the unit.

Always observe the installation directions.

Secure the specified distance between the servo drive unit and control panel's inner wall, and between other devices.

Do not install or run a servo drive unit or servomotor that is damaged or missing parts.

Do not block the intake or exhaust ports of the servomotor provided with a cooling fan.

Do not let foreign objects enter the servo drive units or servomotors. In particular, if conductive objects such as screws or metal chips, etc., or combustible materials such as oil enter, rupture or breakage could occur.

The servo drive units and servomotors are precision devices, so do not drop them or apply strong impacts to them.

CAUTION

Store and use the units under the following environment conditions.

	Environment	Conditions
		Servo drive unit	Servomotor
	Ambient temperature	0°C to +55°C (with no freezing)	0°C to +40°C (with no freezing)

		dust or conductive particles
	Altitude	1,000m or less above sea level
	Vibration	4.9m/s2 (0.5G) or less	To follow each unit and motor
			specifications

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.

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 servomotor.

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

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

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 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 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.

(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 servo drive unit or servomotor.

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 servo drive unit could be affected by magnetic noise.

Use the servo drive unit, servomotor 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 is 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 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.).

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

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 carry out maintenance and inspection after backing up the servo drive unit's programs or parameters.

The capacity of the electrolytic capacitor will drop over time. 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, save 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.

(7) Disposal

Treat this unit as general industrial waste. Note that MDS Series unit with a heat dissipating 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 servo drive unit or servomotor parts.

Dispose of the battery according to local laws.

(8) General precautions

The drawings given in this Specifications and Maintenance Instruction Manual show the covers and safety partitions, etc., removed to provide a clearer explanation. Always return the covers or partitions to their respective places before starting operation, and always follow the instructions given in this manual.

1-1-3 Cautions for mounting load (prevention of impact on shaft)

[1]When using the servomotor 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.

Servomotor

Double-end stud

Nut

Washer

Pulley

[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 detector installed on the servomotor cannot be changed.

Never hammer the end of the shaft

CAUTION 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 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 "1-1-6 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 shaft facing upward, but this is not a fault.

1-1-5 Shaft characteristics

There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the radial direction and thrust direction, when mounted on the machine, is below the tolerable values given below. These loads may affect the motor output torque, so consider them when designing the machine.

Radial load

Thrust load

L: Length from flange installation surface to center of load weight [mm]

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

CAUTION	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 use a rigid coupling as an excessive bending load will be applied on the shaft and could cause the shaft to break.

Oil/water standards

[1]

The motor protective format uses the IP type, which complies with IEC

Oil or water

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.

[2]

When a gear box is installed on the servomotor, make sure that the oil

level height from the center of the shaft is higher than the values given below. Open a breathing

hole on the gear box so that the inner pressure does not rise.

1-1-7 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 servomotor moves, make sure that excessive stress is not applied on the cable.

If the detector cable and servomotor wiring are stored in a cable bear and the servomotor moves, make sure that the cable bending part is within the range of the optional detector cable.

Fix the detector cable and power cable enclosed with the servomotor.

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

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

The ambient temperature condition for the power supply unit or the drive units is

55°C or less. Because heat can easily accumulate in the upper portion of the

CAUTION units, give sufficient consideration to heat dissipation when designing the panel. If required, install a fan in the panel to agitate the heat in the upper portion of the

units.

1-3-3 Prevention of entering of foreign matter

Treat the cabinet with the following items.

• Make sure that the cable inlet is dust and oil proof by using packing, etc.

• Make sure that the external air does not enter inside by using head radiating holes, etc.

•Close all clearances.

•Securely install door packing.

•If there is a rear cover, always apply packing.

•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.

•After installing each unit, avoid machining in the periphery. If cutting chips, etc., stick onto the electronic parts, trouble may occur.

•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).

1-3-5 Heating value

Each heating value is calculated with the following values.

The values for the servo drive unit are for a stall output, and the values for the spindle drive unit are for a continuous rated output. The value for the power supply unit includes the AC reactor's heating value.

Design the panel's heating value taking the actual axis operation (load rate) into

consideration. With a general machine tool, the servo drive unit's load rate is POINT approx. 50%, so the heating values inside the panel are half the values shown

above. (Excluding the power supply and spindle drive unit.)

(Example 1)

When using MDS-C1-CV-260, MDS-C1-SP[]-185 and MDS-C1-V2-3535

Total heating value

= (40 + 220) + (62 + 280) + (51 + 209) = 862 [W]

Heating value in panel = (40) + (62) + (51 × 0.5) = 127.5 [W]

1. Installation

1-3-6 Heat radiation countermeasures

In order to secure reliability and life, design the temperature in the panel so that the ambient temperature of each unit is 55°C or less.

If heat accumulates at the top of the unit, etc., install a fan so that the temperature in the panel remains constant.

(Note) Due to the structure, heat easily accumulates at the top of the unit. Install a fan in the power distribution panel to circulate the heat at the top of the unit.
