5311 FSSB : ILLEGAL CONNECTION 1. This alarm is issued if, in a pair of axes in which one axis has an
odd servo axis number (parameter No. 1023) and the other has an
even servo axis number that is adjacent to the odd servo axis
number, one of the axes is assigned to an amplifier connected to
an FSSB in a system different from that for the other axis.
2. This alarm is issued if the system does not satisfy a constraint for
performing high–speed HRV control, current control periods for
two FSSBs are different, and it is specified that pulse modules
connected to an FSSB in different paths are to be used.
