1 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.
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 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, injury or damage to equipment.
• When the driver generates an alarm (any of the driver's protective functions is triggered), take measures to hold
the moving part in place since the motor stops and loses its holding torque. Failure to do so may result in injury or
damage to equipment.
• When the driver generates an alarm (any of the driver's protective functions is triggered), first remove the cause and
then clear the protection 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.
• Do not transport, install the product, perform connections or inspections when the power is on. Always turn the
power off before carrying out these operations. Failure to do so may result in electric shock.
• Take measures to keep the moving parts in position for vertical operations such as elevator applications. The motor
loses holding torque when the power is shut off, allowing the moving parts to fall and possibly cause injury or
damage to equipment.
• The brake mechanism of an electromagnetic brake motor is used to keep the moving part and motor in position. Do
not use it as a deceleration/safety brake. Doing so may result in injury or damage to the equipment.
Installation
• Install the motor and driver in the enclosure in order to prevent injury.
• When installing the motor and driver, do not touch the driver without grounding the driver first. Failure to do so
may result in electric shock.
Connection
• Keep the driver's input power voltage within the specified range. Failure to do so may result in 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. Failure to do so may result in fire.
• Do not forcibly bend, pull or pinch the cable. Doing so may cause fire.
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 FREE input to ON while the motor is operating. The motor will stop and lose its holding power.
Doing so may result in injury or damage to equipment.
Repair, disassembly and modification
• Do not disassemble or modify the motor and driver. Doing so may cause injury. Refer all such internal inspections
and repairs to the branch or sales office from which you purchased the product.
Handling the product without observing the instructions that accompany a "Warning"
symbol may result in serious injury or death.
Handling the product without observing the instructions that accompany a "Caution"
