Maintenance and inspection
• Do not touch the connection terminals on the driver while the power is supplied or for at least 10 minutes
after turning off the power. Before making wiring connections or carrying out checks, also wait for the
CHARGE LED to turn off and check the voltage with a tester, etc. Failure to do so may result in electric
shock.
Repair, disassembly and modification
• Do not disassemble or modify the motor and driver. This may cause electric shock or injury. Refer all such
internal inspections and repairs to the branch or sales office from which you purchased the product.
Caution
General
• Do not use the motor and driver beyond its specifications, or electric shock, injury or damage to equipment
may result.
• Keep your fingers and objects out of the openings in the motor and driver, or fire, electric shock or injury
may result.
• Do not touch the motor and driver during operation or immediately after stopping. The surfaces are hot and
may cause a skin burn(s).
Transportation
• Do not hold the motor output shaft or motor cable. This may cause injury.
Installation
• Provide a cover over the rotating parts (output shaft) of the motor to prevent injury.
• To prevent the risk of damage to equipment, leave nothing around the motor and driver that would obstruct
ventilation.
Connection
• The driver’s data edit connector (CN4) and analog I/O signals connector (CN6) are not insulated. When
grounding the positive terminal of the power supply, do not connect any equipment (PC, etc.) whose
negative terminal is grounded. Doing so may cause the driver and these equipment to short, damaging both.
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 input signals to the driver to OFF. Otherwise, the motor may
start suddenly and cause injury or damage to equipment.
• Do not touch the rotating parts (output shaft) of the motor during operation. This may cause injury.
• When moving the motor output shaft by hand while the motor is at standstill, confirm first that the FREE
input of the driver is turned ON. If the FREE input is not ON, an attempt to move the motor output shaft by
hand may result in injury.
• Use a 24 VDC power supply that has been given reinforced insulation between the primary side and
secondary side. Failure to do so may cause electric shock.
• Immediately when trouble has occurred, stop running and turn off the driver power. Failure to do so may
result in fire, electric shock or injury.
• To prevent electric shock, use only an insulated screwdriver to adjust the driver’s switches.
• The motor’s surface temperature may exceed 70 °C (158 °F), even under normal
operating conditions. If a motor is accessible during operation, post a warning label
shown in the figure in a conspicuous position to prevent the risk of skin burn(s).
Warning label
Maintenance and inspection
• To prevent the risk of electric shock, do not touch the terminals while measuring the insulation resistance or
conducting a voltage-resistance test.
Disposal
• To dispose of the motor or driver, disassemble them into parts and components as much as possible and
dispose of individual parts/components as industrial waste.
