Biennial Inspections
Replace the encoder backup batteries and check the cableveyors in the transfer unit for any abnormality.
RC8 series robot controller does not have a memory backup battery; However, it contains a battery that maintains the date and time of the internal clock. The life span of the internal clock battery is 10 years. At the biennial inspection, check if the battery's life span (10 years) has arrived. If it has arrived, please contact the DENSO Robot service division or a dealer where you have purchased our robot to request the battery replacement.
For details, refer to the "Battery Replacement for the Internal Clock" of RC8 SERIES ROBOT CONTROLLER MANUAL.
Replacement of Backup Batteries
The position data of the encoder contained in the servomotor is stored in the internal memory of the encoder. The backup battery for each memory retains the above data, while the power to the robot controller is turned OFF. However, these batteries have a limited lifetime and must, therefore, be replaced regularly.

Inspection of Cableveyors
The cableveyors may be abnormally worn due to abrasion with each other.
Before inspection, turn off the power and perform inspection as follows:
