Restoring Data; Battery Replacement - Omron NY532-1*00-112*13**0 User Manual

Precautions for Safe Use
• Always use the axis at a constant velocity for the MC_DigitalCamSwitch (Enable Digital Cam
Switch) instruction.
If you set the Count Mode to Rotary Mode, the following operation will occur if you use OnCompen-
sation or OffCompensation and the axis velocity changes abruptly.
• If the value of OnCompensation or OffCompensation is equivalent to the time for half a rotation or
more, InOperation will be FALSE.
• If the value of OnCompensation results in exceeding LastOnPosition, the output timing will be un-
stable.
FirstOnPosition
OnCompensation
• If the value of OffCompensation results in exceeding FirstOnPosition, the output timing will be un-
stable.

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 Replacement

• 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.
• The Battery may leak, rupture, heat, or ignite. Never short-circuit, charge, disassemble, heat, or in-
cinerate the Battery or subject it to strong shock.
