Description

Communication with the sensor board failed.

Remedy · Remède

1. Move the robot to a safe pose. 2. Turn the controller OFF, then ON again. If this alarm occurs again, go to the next step. 3. Remove any sources of noise in the sensor system. Turn the controller OFF, then ON again. If this alarm occurs again, go to the next step. 4. Make sure that the shield lines of the cables are connected to the frame ground. Make sure that the peeled part of the cable in the cabinet is properly connected to the earth plate. If this alarm occurs again, go to the next step. 5. This alarm occurs when the number of errors exceeds the serial allowed number or the total allowed number. Therefore, this alarm can be avoided by increasing the serial allowed number (system var $CCS_GRP.$ALARMSERAL) or the total allowed number (system var $CCS_GRP.$ALARMTOTAL). If the alarm still occurs after increasing these numbers, go to the next step. 6. Replace the sensor board.
