• Because backup power supply voltage for encoder decreased(less than 2.6V), position data of the encoder disappered.
• Whenever a new motor was used, this error occurred.
• Reset the alarm. Adjust the home position again.
• Check the battery voltage for encoder. (more than 2.8V)
• Replace the battery.
• If the error occurs again, replace the encoder.
• Because it is charged the backup condenser, don't turn off power supply for a few minutes.
Voltage of backup battery for encoder has decreased.
(less than 2.8V) (In case leaving this voltage as it is, the backup error occurs and position data disappears.)
• Check the battery voltage for encoder. (more than 2.8V)
• Replace the battery
• Check that the ambient temperature is not too high.
• Check the load again.
• Check the primary power supply voltage (220V+10%).
• If the error occurs again, replace the WRCA01 circuit board, the encoder.
• A collision from interferrence between robot and peripheral device etc.
was detected.
• The collision was mis-detected by the normal movement of the robot, because the detection level was small.
• Remove the object after resetting the alarm or move the robot to the safety position.
• When the alarm cannot be reset because the robot comes in contact with the object, invalidate this function in the collision detection level set file or enlarge the detection level and move the robot to the safety position.
• Enlarge the detection level so as not to mis-detect the collision detection by the normal movement of the robot. Moreover, set accurate information of the weight of the tool.
