or injury.
Handling of this product
Do not transport, install, connect or inspect the product while the power is supplied. Always
turn o the power before carrying out these operations.
Electric shock or damage to equipment
may result.
The terminals on the driver marked
symbol indicate the presence of high voltage.
Do not touch these terminals while the power is supplied.
Doing so may result in re or electric
shock.
Do not use the brake mechanism of the electromagnetic brake motor as a safety brake.
Doing so may result in injury or damage
to equipment.
Only qualied and educated personnel should be allowed to perform installation,
connection, operation and inspection/troubleshooting of the product.
Handling by unqualied and uneducated
personnel may result in re, electric
shock, injury, or damage to equipment.
Use an electromagnetic brake motor in an application of vertical drive such as elevating
equipment.
Failure to do so may result in injury or
damage to equipment.
If the driver protective function is activated, remove the cause before resetting the
protective function.
Installation
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.
Connection
Do not machine or modify the connection cable.
This may result in re, electric shock or
damage to equipment.
Do not apply any excessive force to the motor connector.
Do not forcibly bend, pull or pinch the cable.
Do not remove the connector cap until the connection cable is connected so that the O-ring
of the connector connection on the motor is not damaged.
Securely connect and ground in accordance with the connection diagram.
Be sure to observe the specied cable sizes.
Operation
Do not turn the MB-FREE input ON when the electromagnetic brake motor is used in an
application of vertical drive such as elevating equipment. The motor will lose its holding force.
This may result in injury or damage to
equipment.
When the electromagnetic brake motor is used in an application of vertical drive such as
elevating equipment, do not set the “Electromagnetic brake function at alarm” parameter to
“Lock after coasting to a stop.”
Always keep the power supply voltage of the driver within the specied range.
Failure to do so may result in re or
electric shock.
Use a motor and driver only in the specied combination.
Failure to do so may result in re,
electric shock or damage to equipment.
When the electromagnetic brake motor is used in an application of vertical drive such as
elevating equipment, operate it after checking the condition of a load suciently so that a load
in excess of the rated torque is not applied or a small value is not set in the torque limiting value.
Failure to do so may result in injury or
damage to equipment.
