12.1.3 Replacing the Battery for Absolute Encoders
Replace the absolute encoder battery (purchased by the user) as outlined below. With an ER 6-V
C-type lithium battery manufactured by Toshiba Battery Co., Ltd. the service life is about 10 years.
1. Turn ON the control power supply of SERVOPACK and wait at least 30 minutes after
SENS ON command is transmitted until the capacitor inside the encoder is charged.
2. Replace the battery. The SERVOPACK power supply may be ON or OFF when the battery
is replaced.
Encoder multiturn data will not be lost if the battery is replaced using the instructions given above.
IMPORTANT
When replacing the battery with the multiturn data remaining, leave the encoder power supply for at least 30
minutes (SENS_ON command transfer).
