Operation
• Do not connect a three-phase power supply to the U, V, or W output terminals.
Doing so may result in injury or fire.
• Securely fasten the power supply terminal screws and motor output terminal screws.
Not doing so may result in fire.
• Never touch any rotating motor parts while the motor is running.
Doing so may result in injury.
• Conduct trial operation on the servomotor alone with the motor shaft disconnected from machine to
avoid any unexpected accidents.
Not doing so may result in injury.
• Before starting operation with a machine connected, change the settings to match the parameters of
the machine.
Starting operation without matching the proper settings may cause the machine to run out of control or
malfunction.
• Before starting operation with a machine connected, make sure that an emergency stop can be applied
at any time.
Not doing so may result in injury.
