2 Safety precautions
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 C.OFF (all windings off) input to "ON" while the motor is
operating. The motor will stop and lose its holding ability, which may result in
injury or damage to equipment.
Repair, disassembly and modification
• Do not disassemble or modify the motor or driver. This may cause fire, electric
shock or injury.
General
• Do not use the motor and driver beyond their 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.
• Do not touch the motor or driver during operation or immediately after stopping.
The surfaces are hot and may cause a burn.
• If the power supply cable or motor cable connected the driver are forcibly bent or
pulled, the driver will receive stress and may suffer damage.
Transportation
• Do not hold the motor output shaft or motor cable. This may cause injury.
Installation
• Keep the area around the motor and driver free of combustible materials in order
to prevent fire or a burn.
• To prevent the risk of damage to equipment, leave nothing around the motor and
driver that would obstruct ventilation.
• Provide a cover over the rotating parts (output shaft) of the motor to prevent
injury.
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 inputs to the driver to
"OFF." Otherwise, the motor may start suddenly and cause injury or damage to
equipment.
• Before moving the motor directly (as in the case of manual positioning), confirm
that the driver C.OFF (all windings off) input is "ON" to prevent injury.
