8.11 Er.04, Er.05, Er.06, Er.14: Self-diagnostic Function
The self-diagnostic function outputs warnings for the thyristor
’
s open/short circuit and the
load
’
s open/short circuit on the basis of internal speculation using values of the current
detected with the unit
’
s built-in CT, the signal output from the thyristor, and the current and
voltage detected with a conversion board if used. It does not actually check if the thyristor and
loads are open or short-circuited. With this mechanism, this function may output false warnings
depending on the load type. You can forcibly clear false warnings by setting [F700: Self-
diagnosis stop] to [0: Suspend self-diagnosis].
Self-diagnosis targets differ according to the unit status.
Conversion board category A: UG-TB3, UG-TB3U, UG-TB3H, UG-TB3HU
Conversion board category B: When no conversion board or a model other than those listed
above is used
Conversion board category A Conversion board category B
