WARNING
•
Do not use the product in explosive or corrosive environments, in the presence of ammable gases, in places subjected to splashing
water, or near combustibles. Doing so may result in re or injury.
•
Do not transport, install, connect or inspect the product while the power is supplied. Always turn o the power before carrying out
these operations. Damage to equipment may result.
•
Do not use a motor in vertical drive such as elevating equipment. When the driver protective function is activated, the motor will stop
operating. The moving part may fall, leading to injury or damage to equipment.
•
Do not touch the motor or driver when conducting the insulation resistance measurement or dielectric strength test. Accidental
contact may result in electric shock.
•
Do not disassemble or modify the driver. Doing so may cause injury or damage to equipment. Refer all such internal inspections and
repairs to the branch or sales oce from which you purchased the product.
•
Only qualied and educated personnel should be allowed to perform installation, connection, operation and inspection/troubleshooting
of the product. Handling by unqualied and uneducated personnel may result in re, injury or damage to equipment.
•
Use a motor and driver only in the specied combination. Failure to do so may result in re or damage to equipment.
•
If the driver protective function was activated, remove the cause before resetting 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.
•
Install the driver in an enclosure. Failure to do so may result in injury.
•
Always keep the power supply voltage of the driver within the specied range. Failure to do so may result in re.
•
Connect the cables securely according to the wiring example. Failure to do so may result in re or damage to equipment.
•
Be sure to observe the specied cable sizes. Failure to do so may result in re or damage to equipment.
•
For the driver 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.
•
If the motor is operated by turning on and o the power supply, turn o the driver power in the event of a power failure. Otherwise,
the motor may suddenly start when the power is restored, causing injury or damage to equipment.
•
Always turn o the power before performing maintenance or inspection. Failure to do so may result in electric shock.
CAUTION
•
Do not use the driver beyond the specications. Doing so may result in re, injury or damage to equipment.
•
Do not touch the driver during operation or immediately after stopping. The surface is hot, and this may cause a skin burn(s).
•
Keep the area around the driver free of combustible materials. Failure to do so may result in re or a skin burn(s).
•
Do not leave anything around the driver that would obstruct ventilation. Doing so may result in damage to equipment.
•
Do not shut o the negative side of the power supply. Also, make sure that the wiring for the power supply does not disconnect. This
may result in damage to equipment.
•
Securely install the driver to the mounting plate. Inappropriate installation may cause the driver to detach and fall, resulting in injury
or damage to equipment.
•
Be sure to ground the motor and driver to prevent them from being damaged by static electricity. Failure to do so may result in re or
damage to equipment.
•
Pay enough attention to safe operation when starting and stopping the motor by switching ON-OFF of the power supply. Failure to
do so may result in injury or damage to equipment.
•
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.
•
Immediately when trouble has occurred, stop operation and turn o the driver power. Failure to do so may result in re, electric shock
or injury.
•
Before turning on the power to the driver, make sure to turn all input signals of the driver to OFF. Otherwise, the motor may suddenly
start when the power is on, leading to injury or damage to equipment.
