Applicable to conditions for a short time, for example, in transit.
Not enabled in the initial state.
Available when the FR-A8NC is installed.
Displayed on the operation panel (FR-DU08) only.
Signal assignment is not available for one of the three terminals (terminal RYB).
50 to 60 Hz
The following signals can be assigned to Pr.3, Pr.4, or Pr.7 (Input terminal function selection):
Converter stop (SOF), Converter reset (RES), External thermal relay input (OH), and Box-type
reactor overheat protection (LOH).
The following signals can be assigned to Pr.11, Pr.12, or Pr.16 (Output terminal function
selection): Inverter run enable (RDY), During converter reset (RSO), Converter running (CVO),
Overload warning (OL), Power supply phase detection (PHS), Instantaneous power failure detection
(IPF), Regenerative drive recognition (Y7), Electronic thermal O/L relay pre-alarm (THP), Fan fault
output (FAN), Heatsink overheat pre-alarm (FIN), During retry (RTY), Life alarm (Y14), Maintenance
timer alarm (Y15), Instantaneous power failure detection hold (Y16), PU stopped (PS), Box-type
reactor overheat pre-alarm (FTP), Alarm (LF), and Fault (ALM).
Input power value (with regenerative driving indication)
Power supply frequency, input current, input voltage, fault indication, bus voltage (output voltage),
electronic thermal relay load factor, cumulative energization time, cumulative power, input power
(with regenerative driving indication), I/O terminal status, electricity cost, option connector status
When a protective function is activated, a fault indication is displayed.
When a protective function is activated, a fault indication is displayed, and the latest monitored value
of input voltage, input current, bus voltage, cumulative energization time are recorded. The last eight
fault records are stored.
