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.
Warning
Handling the product without observing the instructions that accompany a
“Warning” symbol may result in serious injury or death.
General
• Do not use the product in explosive or corrosive environments, in the presence
of flammable gases, locations subjected to splashing water, or near
combustibles. Doing so may result in fire, electric shock or injury.
• Assign qualified personnel the task of installing, wiring, operating/controlling,
inspecting and troubleshooting the product. Failure to do so may result in fire,
electric shock or injury.
• The motor will lose its holding torque when the power supply or motor
excitation turned off. If this product is used in an lifting application, be sure to
provide a measure for the position retention of moving parts. Failure to provide
such a measure may cause the moving parts to fall, resulting in injury or
damage to the equipment.
• Do not use the motor's built-in electromagnetic brake mechanism for stopping
or for safety purposes. Using it for purposes other than holding the moving
parts and motor in position may cause injury or damage to equipment.
• With certain types of alarms (protective functions), the motor may stop when
the alarm generates and the holding torque will be lost as a result. This will
result in injury or damage to equipment.
• When the alarm is generated, first remove the cause and then clear the alarm.
Continuing the operation without removing the cause of the problem may
cause malfunction of the motor and driver, leading to injury or damage to
equipment.
Connection
• Keep the driver’s input-power voltage within the specified range to avoid fire.
• For the driver's power supply, use a DC power supply with reinforced
insulation on its primary and secondary sides. Failure to do so may result in
electric shock.
• Connect the cables securely according to the wiring diagram in order to
prevent fire.
• Do not forcibly bend, pull or pinch the cable or lead wire. Doing so may fire.
This will cause stress to the connecting section and may result in damage to
equipment.
Operation
• Turn off the driver 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.
• Do not turn the excitation to off while the motor is operating. The motor will
stop and lose its holding ability, which may result in injury or damage to
equipment.
• Configure an interlock circuit using a sequence program so that when a
RS-485 communication error occurs, the entire system including the driver will
operate on the safe side.
Repair, disassembly and modification
• Do not disassemble or modify the motor and driver. This may cause injury.
Refer all such internal inspections and repairs to the branch or sales office
from which you purchased the product.
Caution
Handling the product without observing the instructions that accompany a
“Caution” symbol may result in injury or property damage.
General
• Do not use the motor and driver beyond its specifications, or injury or damage
to equipment may result.
• Keep your fingers and objects out of the openings in the motor and driver, or
fire or injury may result.
• Do not touch the motor and driver during operation or immediately after
stopping. The surface is hot and may cause a skin burn(s).
Transportation
• Do not hold the motor output shaft, cable or lead wire. This may cause injury.
Installation
• Install the motor and driver in the enclosure in order to prevent injury.
• Keep the area around the motor and driver free of combustible materials in
order to prevent fire or a skin burn(s).
• Provide a cover over the rotating parts (output shaft) of the motor to prevent
injury.
Connection
• The driver’s power supply connector (CN1), I/O connector (CN2),
communication connector (CN3) and RS-485 communication connector
(CN6/CN7) 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 driver and PC to short,
damaging both.
• When connecting, check the silk screen of the driver and pay attention to the
polarity of the power supply. Reverse-polarity connection may cause damage
to the driver. The power-supply circuit and the RS-485 communication circuit
are not insulated. Therefore, when controlling multiple drivers via RS-485
communication, the reverse polarity of the power supply will cause a short
circuit and may result in damage to the drivers.
Operation
• Use a motor and driver only in the specified combination. An incorrect
combination may cause a fire.
• Provide 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.
• Before supplying power to the driver, turn all control input to the driver to OFF.
Otherwise, the motor may start suddenly at power ON and cause injury or
damage to equipment.
• Set the speed and acceleration/deceleration rate at reasonable levels.
Otherwise, the motor will misstep and the moving part may move in an
unexpected direction, resulting in injury or damage to equipment.
• Do not touch the rotation part (output shaft) during operation. This may cause
injury.
• Before moving the motor directly with the hands, confirm that the power supply
or motor excitation turned off and motor current is cut off. Failure not to do so
may result in injury.
• The 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
• Immediately when trouble has occurred, stop running and turn off the driver
power. Failure to do so may result in fire or injury.
• Static electricity may cause the driver to malfunction or suffer damage. While
the driver is receiving power, do not touch the driver. Use only an insulated
screwdriver to adjust the driver's switches.
Disposal
• To dispose of the motor and driver, disassemble it into parts and components
as much as possible and dispose of individual parts/components as industrial
waste. If you have any question, contact your nearest Oriental Motor branch or
sales office
