Output Function Summary Table
Output current is more than the set Threshold 2 for the
overload signal (set with C111)
Input signal level at terminal [O] is below threshold (set with
B070)
Input signal level at terminal [OI] is below threshold (set with
B071)
Input signal level at terminal [O2] is below threshold (set with
B072)
Stage #1 inverter is indicating to Stage # inverter that the
Process Variable (PV) is in saturation. The system needs
Stage #2 output contribution to stabilize system control.
The communications watchdog timer (period specified by
C077) has timed out
Boolean operation specified by C144 has a logical "1" result
Boolean operation specified by C147 has a logical "1" result
Boolean operation specified by C150 has a logical "1" result
Boolean operation specified by C153 has a logical "1" result
Boolean operation specified by C156 has a logical "1" result
Boolean operation specified by C159 has a logical "1" result
Capacitor bank on the main board needs replacement
Cooling fan is enabled but it is rotating below normal speed
ON while the inverter receives a FW or REV command
Inverter heat sink temperature is above the threshold set by
C064
Easy sequence function, general output 1
Easy sequence function, general output 2
Easy sequence function, general output 3
