For Safe Use

WARNING

Do not open or remove the front cover while the power is ON or during operation. The high voltage terminals and

charged sections will be exposed, and this could result in electric shocks.

Do not remove the front cover even when the power is OFF, except for the wiring works or periodic inspections.

The inside of the controller and drive unit are charged, and this could result in electric shocks.

Always wait at least 15 minutes after turning the power OFF. Then, check the voltage with a tester, etc., before

wiring works, inspections or connecting with peripheral devices. Failure to observe this could result in electric

shocks.

Earth ground the controller, drive unit and motor according to the local laws. (In Japan, ground the 200V Series

input products with Class C or higher protective grounding and the 400V Series input with Class D or higher

protective grounding.)

All wiring works, maintenance and inspections must be carried out by a qualified technician. Failure to observe this

could result in electric shocks. Contact your nearby Service Center or Service Station for replacing parts and

servicing.

Wire the controller, drive unit and motor after installation. Failure to observe this could result in electric shocks.

Do not operate the switches with wet hands. Failure to observe this could result in electric shocks.

Do not damage, apply excessive stress, place heavy things on or sandwich the cables. Failure to observe this could

result in electric shocks.

Insulate the power lead using a fixed terminal block. Failure to observe this could result in electric shocks.

CAUTION

Install the controller, drive unit, motor and regenerative resistor on non-combustible material. Installation directly on

or near combustible materials could result in fires.

If any malfunction in the unit is observed, shut off the power at the unit’s power supply side. Continuous flow of large

current could result in fires.

Install an appropriate no fuse breaker (NFB) and contactor (MC) on the power input section of the drive unit and

configure the sequence that shuts the power off upon drive unit’s emergency stop or alarm.

When a breaker is shared for multiple power supply units, the breaker may not function upon short-circuit failure in

a small capacity unit. Do not share a breaker for multiple units as this is dangerous.

Incorrect wiring and connections could cause the devices to damage or burn.

3. Items related to prevention of bodily injury or property damage

DANGER

When transporting or installing a built-in IPM spindle or linear servomotor, be careful so that your hand or property

will not be trapped in the motors or other metal objects. Also keep the devices with low magnetic tolerance away

from the product.

CAUTION

Do not apply voltages to the connectors or terminals other than voltages indicated in the connection manual for the

controller or specifications manual for the drive unit. Failure to observe this could cause bursting, damage, etc.

Incorrect connections could cause the devices to rupture or damage, etc. Always connect the cables to the indicated

connectors or terminals.

Incorrect polarity (+ -) could cause the devices to rupture or damage, etc.

Persons wearing medical devices, such as pacemakers, must stay away from this unit. The electromagnetic waves

could adversely affect the medical devices.

Fins on the rear of the unit, regenerative resistor and motor, etc., will be hot during operation and for a while after

the power has been turned OFF. Do not touch or place the parts and cables, etc. close to these sections. Failure

to observe this could result in burns.

the spindle during rotation.

4. General precautions

Always follow the precautions below. Incorrect handling could result in faults, injuries or electric shocks, etc.

(1) Transportation and installation

CAUTION

Correctly transport the products according to the mass.

Use motor’s suspension bolts to transport the motor itself. Do not use it to transport the motor after installation onto

the machine.

Do not stack the products exceeding the indicated limit.

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

Do not transport the controller or drive unit by suspending or holding the connected wires or cables.

Do not hold the front cover when transporting the unit, or the front cover could come off, causing the unit to drop.

Install on a non-combustible place where the unit’s or motor’s mass can be withstood according to the instruction

manual.

The motor does not have a complete water-proof (oil-proof) structure. Do not allow oil or water to contact or enter

the motor. Prevent the cutting chips from being accumulated on the motor as they easily soak up oil.

When installing the motor facing upwards, take measures on the machine side so that gear oil, etc., will not enter

the motor shaft.

Do not remove the detector from the motor. (The detector installation screw is treated with sealing.)

Do not allow foreign matters, especially, conductive foreign matters such as screws or metal chips, or combustible

foreign matters such as oil, to enter the controller, drive unit or motor. Failure to observe this could result in rupture

or damage.

Do not get on the product or place heavy objects on it.

Provide prescribed distance between the controller/drive unit and inner surface of the control panel/other devices.

Do not install or operate the controller, drive unit or motor that is damaged or has missing parts.

Take care not to cut hands, etc. with the heat radiating fins or metal edges.

Do not block the intake/outtake ports of the motor with the cooling fan.

Install the controller’s display section and operation board section on the spot where cutting oil will not reach.

The controller, drive unit and motor are precision devices, so do not drop or apply thumping vibration and strong

impacts on them.

Hard disk unit is a precision device, so do not drop or apply strong impacts on it.

Store and use the units according to the environment conditions indicated in each specifications manual.

Securely fix the motor to the machine. The motor could come off during operation if insecurely fixed.

CAUTION

Always install the motor with reduction gear in the designated direction. Failure to observe this could result in oil

leaks.

Always install a cover, etc., over the shaft so that the rotary section of the motor cannot be touched during motor

rotation.

When installing a coupling to the servomotor shaft end, do not apply impacts by hammering, etc. The detector could

be damaged.

Use a flexible coupling when connecting with a ball screw, etc., and keep the shaft core deviation smaller than the

tolerable radial load of the shaft.

Do not use a rigid coupling as an excessive bending load will be applied on the shaft and could cause the shaft to

break.

Do not apply a load exceeding the tolerable level onto the motor shaft. The shaft or bearing could be damaged.

Before using this product after a long period of storage, please contact the Mitsubishi Service Station or Service

Center.

Following the UN recommendations, battery units and batteries should be transported based on the international

regulations such as those determined by International Civil Aviation Organization (ICAO), International Air

Transport Association (IATA), International Maritime Organization (IMO) and U.S. Department of Transportation

(DOT).

(2) Items related to wiring

CAUTION

Correctly wire this product. Failure to observe this could result in motor runaway, etc.

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

Correctly connect the output side (terminal U, V, W). The motor will not run properly if incorrectly connected.

Always install an AC reactor per each power supply unit.

Always install an appropriate breaker per each power supply unit. A breaker cannot be shared for multiple power

supply units.

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

When using an inductive load such as relays, always connect a diode in parallel to the load as a noise

countermeasure.

When using a capacitive load such as a lamp, always connect a protective resistor serially to the load to suppress

rush currents.

Do not mistake the direction of the surge absorption diode to be installed on the DC relay for the control output

signal. If mistaken, the signal will not be output due to fault in the drive unit, and consequently the protective circuit,

such as emergency stop, could be disabled.

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

Do not connect or disconnect the PCBs while the power is ON.

Do not pull the cables when connecting/disconnecting them.

Securely tighten the cable connector fixing screw or fixing mechanism. The motor could come off during operation

if insecurely fixed.

Always treat the shield cables indicated in the Connection Manual with grounding measures such as cable clamps.

Separate the signal wire from the drive line or power line when wiring.

Use wires and cables whose wire diameter, heat resistance level and bending capacity are compatible with the

system.

Ground the device according to the requirements of the country where the device is to be used.

Wire the heat radiating fins and wires so that they do not contact.

When using the RS-232C device as a peripheral device, caution must be paid for connector connection/

disconnection. Always use a double-OFF type AC power supply switch on the device side, and connect/disconnect

the connector with the AC power supply on the device side OFF.

unpredictable operations depending on the machine.

Do not make drastic adjustments or changes as the operation could become unstable.

CAUTION

Install an external emergency stop circuit so that the operation can be stopped and the power turns OFF

immediately when unforeseen situation occurs. A contactor, etc., is required in addition to the shutoff function

mounted in the controller.

Turn OFF the power immediately if any smoke, abnormal noise or odor is generated from the controller, drive unit

or motor.

Only a qualified technician may disassemble or repair this product.

Do not alter.

Use a noise filter, etc. to reduce the effect of electromagnetic disturbances in the case where electromagnetic

disturbances could adversely affect the electronic devices used near the drive unit.

Use the drive unit, motor and each regenerative resistor with the designated combination. Failure to observe this

could result in fires or faults.

The combination of the motor and drive unit that can be used is determined. Be sure to check the models of motor

and drive unit before test operation.

The brakes (electromagnetic brakes) mounted in the servomotor are used for the purpose of holding, and must not

be used for normal braking. Also, do not run the motor with the motor brake applied. Motor brake is used for the

purpose of holding.

For the system running via a timing belt, install a brake on the machine side so that safety can be ensured.

Be sure to confirm SERVO OFF (or READY OFF) when applying the electromagnetic brake. Also, be sure to

confirm SERVO ON prior to releasing the brake.

When using the DC OFF type electromagnetic brake, be sure to install a surge absorber on the brake terminal.

Do not connect or disconnect the cannon plug while the electromagnetic brake’s power is ON. The cannon plug

pins could be damaged by sparks.

After changing programs/parameters, or after maintenance/inspection, always carry out a test operation before

starting actual operation.

Use the power that are complied with the power specification conditions (input voltage, input frequency, tolerable

instantaneous power failure time) indicated in each specifications manual.

When making detector cables, do not mistake connection. Failure to observe this could result in malfunction,

runaway or fire.
