Note
Note
The items under this heading contain important handling instructions that the
user should observe to ensure safe use of the product.
Warning
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, electric shock 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, electric shock or injury.
• 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.
• Provide a means to hold the moving parts in place for applications involving vertical travel. In the position
control mode, the motor will lose its holding torque when the power is turned off. In all other modes, the
holding torque will be lost when the motor stops. Loss of holding torque may cause the moving part to drop,
resulting in injury or damage to the equipment.
• The terminals on the driver’s front panel marked with
symbol indicate the presence of high
voltage. Do not touch these terminals while the power is on to avoid the risk of fire or electric shock.
• When the driver generates an alarm (=any of the driver’s protective functions is triggered), the motor will
stop and lose its holding torque. Accordingly, provide measures to hold the moving part in place in the
event of an alarm. Failure to do so may result in injury or equipment damage.
• When the driver’s protection function 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.
Installation
• The motor and driver are Class I equipment. When installing the motor and driver, do not touch them or
ground the motor and driver first. Failure to do so may cause electric shock.
• Install the motor and driver in an enclosure in order to prevent electric shock or injury.
Connection
• Keep the driver’s input-power voltage within the specified range to avoid fire and electric shock.
• Connect the cables securely according to the wiring diagram in order to prevent fire and electric shock.
• Do not forcibly bend, pull or pinch the cable. Doing so may fire and electric shock.
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
ability, which may result in injury or damage to equipment.
