• An alarm or warning may occur if communications are performed with the
host controller while the SigmaWin+ or Digital Operator is operating.
If an alarm or warning occurs, it may interrupt the current process and stop the
system.
• After you complete trial operation of the machine and facilities, use the Sig-
maWin+ to back up the settings of the SERVOPACK parameters. You can use
them to reset the parameters after SERVOPACK replacement.
If you do not copy backed up parameter settings, normal operation may not be
possible after a faulty SERVOPACK is replaced, possibly resulting in machine
or equipment damage.

Maintenance and Inspection Precautions
• Do not change any wiring while power is being supplied.
There is a risk of electric shock or injury.
• Wiring and inspections must be performed only by qualified engineers.
There is a risk of electric shock or product failure.
• 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.
• Before you replace a SERVOPACK, back up the settings of the SERVOPACK
parameters. Copy the backed up parameter settings to the new SERVOPACK
and confirm that they were copied correctly.
If you do not copy backed up parameter settings or if the copy operation is not
completed normally, normal operation may not be possible, possibly resulting
in machine or equipment damage.
• Discharge all static electricity from your body before you operate any of the
buttons or switches inside the front cover of the SERVOPACK.
There is a risk of equipment damage.
