Design and Installation
j Lithium Battery (Recommended Products)
With an absolute encoder, a battery must be used in order to retain position data when the power is
turned OFF.
Note 1. When power is turned OFF internally at the Position Driver, the battery voltage is not moni-
Note 2. Use one battery for one Position Driver. (The estimated battery service life is calculated based
Note 3. The Toshiba lithium battery does not have a connector for BAT connections. It is necessary to
j Replacing the Battery
The following method can be used to replace the battery while retaining the absolute encoder’s rotation
data.
Note 1. After step 1 above has been implemented, the encoder will operate normally even with the
Note 2. While replacing the battery, be careful not to short-circuit the plus and minus terminals.
Note 3. When disconnecting the lead wires, disconnect the plus and minus terminals separately. Dis-
Note 4. Be sure to use the prescribed method for disposing of used batteries. In particular, do not un-
j Setting up the Absolute Encoder
Setup is required to set the amount of machine rotation to zero for trial operation of the Servomotor or
when the absolute encoder has been left disconnected from the battery for more than two days. (This is
because the voltage of the capacitor inside the absolute encoder will drop if a battery is left unconnected
for more than two days, possibly interfering with the proper operation of internal elements.)
