DANGER
• Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
WARNING
• Wiring and inspections must be performed only by qualified engineers
There is a risk of electric shock or product failure.
• If you replace a Servomotor with a Holding Brake, secure the machine
before you replace the Servomotor.
There is a risk of injury or equipment damage if the equipment falls.
CAUTION
• Wait for six minutes after turning OFF the power supply and then make
sure that the CHARGE indicator is not lit before starting wiring or
inspection work. Do not touch the power supply terminals while the
CHARGE lamp is lit after turning OFF the power supply because high
voltage may still remain in the SERVOPACK.
There is a risk of electric shock.
• Replace the Battery according to the correct procedure.
If you remove the Battery or disconnect the Encoder Cable while the con-
trol power supply to the SERVOPACK is OFF, the absolute encoder data
will be lost and position deviation may occur.
WARNING
• The product may suddenly start to operate when the power supply is
recovered after a momentary power interruption. Design the machine
to ensure human safety when operation restarts.
There is a risk of injury.
