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
Easy sequence function, general output 4
Easy sequence function, general output 5
Easy sequence function, general output 6
Inverter is ready to accept commands (FW, REV, JOG, etc.)
Inverter output is driving motor in forward direction
Inverter output is driving motor in reverse direction
Inverter trip caused by internal hardware error
[O] input is within comparator window set by B060 and B061
[OI] input is within comparator window set by B063 and
B064
