communication function (CBP_COMRCV_MU (Function ID: 4F2A01)).
‡Note: 64 logical signals are selectable for recording. For example in this purpose, the
user may choose an operation signal on the circuits of the BIO modules (BIOs).
Fault quantities and pre-fault-quantities
(iv)
Quantities that amplitude and phase angle of voltage and current—are memorized in the fault
recorder, as shown in Table 7.1-1. Items, pre-fault quantities just before a fault (i.e., tripping),
are also captured and memorized. Default 10 seconds has been set for setting [Pre-Fault time],
but it is possible to change it to memory the times longer.
