5.6.3 Handling Batteries
In order for the absolute encoder to retain position data when the power is turned
OFF, the data must be backed up by a battery.
Installing the Battery at the Host Device (CN1 - 21, 22)
Lithium battery, by Toshiba: ER6VC3, 3.6V, 2000mAh
Battery Provided for Servo Amplifier (CN8)
Lithium battery: JZSP–BA01 (includes battery and connector)
Battery: Toshiba, ER3 V, 3.6V, 1000mAh

5.6.4 Absolute Encoder Setup
Perform the setup operation for the absolute encoder in the following circumstances:
• When starting the machine for the first time.
• When an encoder backup alarm is generated.
• When the servo amplifier’s power supply is turned OFF and the encoder’s cable is
removed.
The setup operation can be performed by using the hand-held digital operator, the
servo amplifier’s panel operator, or by serial command (see Appendix B2 Auxiliary
Functions).
Install the battery at either the CN1-21, 22 or CN8, NEVER at both simultaneously.
Such a connection would create a circuit between the batteries, which could lead to electric shock, injury, or equipment dam-
age.
