Note
Improperuseofbatterymayresultinbatteryleakagewhichwillcorrodethecomponentsor
causethebatterytoexplode.Observethefollowingprecautionsduringuse:
1. Placethebatteryinthecorrect+/–polarity;
2. If you place a battery that has been used for a long time or a dead battery in the device,
batteryleakagemayoccur,corrodingsurroundingcomponents;asthebatteryisconductive
itmaycauseashortcircuit.Replacethebatteryperiodically(recommendedperiod:Every2
years).
3. NEVER decompose the battery, so as to prevent personal injury by spraying of electrolyte.
4. NEVERputthebatteryinare.Failuretocomplymayresultinanexplosion.
5. Prevent a battery short circuit, and never strip the battery tube. Do not connect metal to
theelectrodesofthebattery.Otherwise,alargecurrentisproduced,weakeningthebattery
power which could result in an explosion due to severe heating.
6. This battery is not chargeable.
7. Reminder:Disposethebatteryaccordingtolocalregulations.
Battery selection:
Select an appropriate battery according to the following table.

Note
*1:Normaloperationmeansthattheabsoluteencodercancount,receiveandsenddata
generated from single rotation and multiple rotations. After the absolute encoder is correctly
connected,itwillworknormallyandreceiveandsenddataafterashortdelay(about5
seconds) when the servo drive is powered on. Switching the absolute encoder from standby
mode to normal operation mode (power is on) requires the motor to rotate at a speed less than
10 RPM, otherwise the drive may report 740 error. In this case, power on the servo drive again.
*2:Standbymodemeansthattheservodriveisnotpoweredonandtheabsoluteencodercan
perform multi-rotation counting by utilizing external battery power. In this mode, the absolute
encoder stops receiving and sending data.
