5.1.1 Replacing Parts of the CPU Unit
CPU unit (JZNC-YRK21-1E) is consisted of the various circuit boards,
CPU circuit board (JANCD-YCP21-E), machine safety CPU circuit board
(JANCD-YSF21-E), and robot I/F circuit board (JANCD-YIF01-E). CPS
unit (JZNC-YPS21-E) is a separated unit and it is arranged to the left side
of CPU unit.
