10. Replacing the Signal Relay Board
WARNING

Only trained personnel should be allowed to maintain this board.

When replacing this board, make sure the power is turned off and pull out the
power plug from the power source. Failure to turn off the power can result in
electric shock and malfunction.
Before turning OFF the power for the replacement, keep the power of the manipulator ON
for more than 30 minutes. It is necessary for the super-capacitor of each motor to retain the
position data.
The charged motor can retain the position data for about 2 hours after its cable is
disconnected. (Motors whose serial number start with “0” can retain the data for about 2
days.)
The position data cannot be retained beyond the time duration mentioned above after which
it will be lost. If this happens, Error 5016/Error 195 will occur when the power is turned
ON. In this case, all the joints need to be calibrated all over again. (Refer to chapter 11.
Calibration.)
