The ERR terminals are used to output the signals of MINI433 link
line errors and selfdiagnosis errors (at operation stop) mentioned
below. Output of these signals is enabled even when the A2C has
stopped operation with the sequence program. (When the
ERR
terminals are turned ON, M9090 is also turned ON.)
Output of error signals other than those mentioned below is also
enabled from the
ERR terminals by turning ON M9089 by use of
