REMARKS
The values of each bit, "0" and "1," indicate "OFF" and "ON."

When the inverter output frequency reaches or exceeds
Pr.13 Starting frequency, the value changes to "1".
When the output frequency reaches the set frequency, the
value changes to "1".
While stall prevention function is activated, the value
changes to "1".
When the output frequency reaches the frequency set in Pr. 42
(Pr. 43 for reverse rotation), the value changes to "1".
When the inverter protective function is activated to stop
the output (fault), the value changes to "1".
When an internal safety circuit fault (E.SAF, E. 6, E. 7, or
E.CPU) occurs, the value changes to "1".
0: Parameter change disabled (X12 signal = "0")
1: Parameter change enabled (X12 signal = "1")
When the output current is higher than the Pr.150 setting
and persists for longer than the time set in Pr.151, the value
changes to "1".
When the output current is lower than the Pr.152 setting and
persists for longer than the time set in Pr.153, the value
changes to "1".
0: inverter resetting/starting after power is turned on
1: Reset canceling
When an alarm (fault) occurs in the inverter, fault code is displayed. (Refer to page 67)
