Backup

• We recommend that you back up the present values of variables while the retained variables are not
refreshed. If you back up while the values of retained variables are refreshed, the data may not be
saved correctly.
For information on Backup Functions and a backup for present values of variables, refer to the NY-
series IPC Machine Controller Industrial Panel PC / Industrial Box PC Software User's Manual (Cat.
No. W558).

Restoring Data

• The absolute encoder home offsets are backed up with a non-volatile memory in the product as ab-
solute encoder information. If any of the following conditions is met, clear the absolute encoder
home offsets from the list of data items to restore, and then restore the data. Then, define the abso-
lute encoder home again. If you do not define home, unintended operation of the controlled system
may occur.
• The Servomotor or Servo Drive was changed since the data was backed up.
• The absolute encoder was set up after the data was backed up.
• The absolute data for the absolute encoder was lost.
• You can partially or cannot at all back up, restore, or compare data of the settings depending on
slaves and Units. Also, you cannot back up, restore, or compare data for disabled slaves or Units.
After you restore data, sufficiently confirm that operation is correct before you start actual operation.

Battery and Fan Replacement

Applicable for products with a cooling layer that has a removable cover.
• Dispose of any Battery that has been dropped on the floor or otherwise subjected to excessive
shock. Batteries that have been subjected to shock may leak if they are used.
• UL standards require that only an experienced engineer replace the Battery. Make sure that an ex-
perienced engineer is in charge of Battery replacement.
