WARNING
•
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.
•
Do not transport, install, connect or inspect the product while the power is supplied. Always turn off the power before
carrying out these operations. This may result in electric shock or malfunction.
•
The terminals on the driver front panel marked with
symbol indicate the presence of high voltage. Do not touch
them while the power is supplied. Doing so may result in fire or electric shock.
•
Do not use the standard type (without electromagnetic brake) in a vertical application. If the driver protective function is
activated, the motor will stop and the moving part will drop, thereby causing injury or damage to equipment.
•
Do not use the brake mechanism of the electromagnetic brake motor as a safety brake. It is intended to hold the moving
part and motor positions. Using it as a safety brake may result in injury or damage to equipment.
•
Do not forcibly bend, pull or pinch the cable. Doing so may result in fire or electric shock.
•
Do not machine or modify the motor cable or connection cable. Doing so may result in fire or electric shock.
•
If the motor is operated in vertical direction, do not turn the FREE input ON. The holding power of the motor will be lost,
causing 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 touch the connection terminals on the driver immediately (until the CHARGE LED turns off) after the power is
turned off. Residual voltage may cause electric shock.
•
Do not disassemble or modify the motor, gearhead and driver. Doing so may result in electric shock, injury, or damage
to equipment. Refer all such internal inspections and repairs to the branch or sales office from which you purchased the
product.
•
Only qualified and educated personnel should be allowed to perform installation, connection, operation and inspection/
troubleshooting of the product. Handling by unqualified and uneducated personnel may result in fire, electric shock, injury
or equipment damage.
•
If the driver protective function was activated, remove the cause before clearing the protective function. 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.
•
The motor and driver are Class I equipment. When installing the motor and driver, ground their Protective Earth Terminals.
Failure to do so may result in electric shock.
•
Install the motor and driver in an enclosure. Failure to do so may result in electric shock or injury.
•
Securely connect the cables in accordance with the connection examples. Failure to do so may result in fire or electric
shock.
•
Be sure to observe the specified cable sizes. Use of unspecified cable sizes may result in fire.
•
Use a motor, gearhead, driver, and regeneration resistor only in the specified combination. Failure to do so may result in
fire, electric shock, or damage to equipment.
•
Always keep the power supply voltage of the driver within the specified range. Failure to do so may result in fire or electric
shock.
•
When using the electromagnetic brake type product in vertical drive such as elevating equipment, be sure to operate after
checking the load condition. If a load in excess of the rated torque is applied or the small torque limiting value is set, the
load may fall. This may cause injury or damage to equipment.
•
Always turn off the power before performing maintenance/inspection. Failure to do so may result in electric shock.
•
Regularly check the openings in the driver for accumulated dust. Accumulated dust may cause fire.
