Safety precautions
The precautions described below are intended to prevent danger or injury to the user
and other personnel through safe, correct use of the product. Use the product only after
carefully reading and fully understanding these instructions.
Description of signs
Handling the product without observing the instructions that
accompany a "WARNING" symbol may result in serious injury
or death.
Handling the product without observing the instructions
that accompany a“CAUTION”symbol may result in injury or
property damage.
The items under this heading contain important handling
instructions that the user should observe to ensure safe use
of the product.
General
yDo not use the product in explosive or corrosive environments, in the presence of
ammable gases, locations subjected to splashing water, or near combustibles. Doing
so may result in re or injury.
yAssign qualied personnel the task of installing, wiring, operating/controlling,
inspecting and troubleshooting the product. Failure to do so may result in re, injury
or damage to equipment.
yWhen the power is shut o or the motor does not maintain excitation, the motor
will lose the holding torque. Take measures to keep the moving parts in position for
vertical operations such as elevator applications. Failure to do so will cause the moving
parts to fall and it may result in injury or damage to equipment.
yDepending on the type of the alarm (protective function), the motor may stop and
lose its holding torque when the alarm generates. This may cause injury or damage to
equipment.
yWhen the motor generates an alarm (any of the motor’s protective functions is
triggered), rst remove the cause and then clear the protective function. Continuing
the operation without removing the cause of the problem may cause malfunction of
the motor, leading to injury or damage to equipment.
Connection
yKeep the motor’s input-power voltage within the specied range to avoid re.
yFor the motor power supply, use a DC power supply with reinforced insulation on its
primary and secondary sides. Failure to do so may cause electric shock.
yConnect the cables securely according to the wiring diagram in order to prevent re.
yDo not forcibly bend, pull or pinch the cable or lead wire. Doing so may cause re.
Applying stress to the connection area of the connectors may cause damage to the
product.

Operation
yTurn o the power in the event of a power failure. Or the motor may suddenly start
when the power is restored and may cause injury or damage to equipment.
yDo not turn the motor excitation OFF while operating. The motor will stop its
operation and lose the holding torque. This may cause injury or damage to equipment.
yCongure an interlock circuit in sequence program so that the system including the
motor operates on the safe side when a RS-485 communication error generates.
Repair, disassembly and modication
yDo not disassemble or modify the motor. Refer all such internal inspections and repairs
to the branch or sales oce from which you purchased the product.
General
yDo not use the motor beyond its specications. Doing so may result in injury or
damage to equipment.
yKeep your ngers and objects out of the openings in the motor. Failure to do so may
result in re or injury.
yDo not touch the motor during operation or immediately after stopping. The surface is
hot and may cause a skin burn(s).
Transportation
yDo not carry the motor by holding the motor output shaft or leadwire/connector
assembly. Doing so may cause injury.
Installation
yInstall the motor in the enclosure in order to prevent injury.
yKeep the area around the motor free of combustible materials in order to prevent re
or a skin burn(s).
yProvide a cover over the rotating parts (output shaft) of the motor. Failure to do so
may result in injury.
Connection
yThe connectors CN1, CN2, CN3 and CN4 of the motor are not electrically insulated.
When grounding the positive terminal of the power supply, do not connect any
equipment (PC, etc.) whose negative terminal is grounded. Doing so may cause the
motor and these equipment to short, damaging both.
yWhen connecting, check the indication of the motor and be sure to observe the
polarity of the power supply. Reverse-polarity connection may cause damage to
the motor. The power-supply circuit and the RS-485 communication circuit are
not electrically insulated. Therefore, when controlling multiple motors via RS-485
communication, the reverse polarity of the power supply will cause a short circuit and
may result in damage to the motors.
Operation
yProvide an emergency stop device or emergency stop circuit external to the
equipment so that the entire equipment will operate safely in the event of a system
failure or malfunction. Failure to do so may result in injury.
yBefore supplying power to the motor, turn all input signals to the motor OFF.
Otherwise, the motor may start suddenly at power on and cause injury or damage to
equipment.
ySet a suitable operation speed and acceleration/deceleration rate. Improper setting
may cause loss of the motor synchronism and moving the load to an unexpected
direction, which may result in injury or damage to equipment.
yDo not touch the rotating part (output shaft) during operation. Doing so may cause
injury.
yWhen rotating the output shaft manually while the motor stops, cut o the motor
current by turning o the power supply or motor excitation. Failure to do so may
cause injury.
yThe motor surface temperature may exceed 70 °C (158 °F) even under
normal operating conditions. If the operator is allowed to approach
the running motor, attach a warning label as shown below in a
conspicuous position. Failure to do so may result in skin burn(s). Warning label
yImmediately when trouble has occurred, stop running and turn o the motor power.
Failure to do so may result in re or injury.
yStatic electricity may cause the motor to malfunction or suer damage. While the
motor is receiving power, do not touch the motor. Always use an insulated slotted
screwdriver to adjust the motor’s switches.
Disposal
yDispose the product correctly in accordance with laws and regulations, or instructions
of local governments.
