Default ID
700 Defines the response to a low analog input
signal. Response settings are as follows:
0 = No Action
1 = Alarm
2 = Alarm and run to PresetAlarmFreq
(P3.3.19)
3 = Fault
4 = Fault
701 Defines the response to activation of an
Ext Fault Close (P3.5.1.7) or Ext Fault
Open (P3.5.1.8). Response settings are as
follows:
0 = No Action
1 = Alarm
2 = Fault
3 = Fault
3-phase 730 Defines the input phase support.
0 = 3-phase support
1 = 1-phase support
NOTE
phase support must be selected.
Fault Stored 727 Defines if the under-voltage fault is stored
in the fault history or not.
0 = Fault Stored
1 = No History
702 Defines the response to an output phase
loss. Response settings are as follows:
0 = No Action
1 = Alarm
2 = Fault
3 = Fault
704 Defines the response to a motor thermal
protection. Response settings are as
follows:
0 = No Action
1 = Alarm
2 = Fault
3 = Fault
104 705 Defines the ambient temperature that is to
generate a response to a Motor Thermal
Protection fault as defined by Motor Therm
Prot (P3.9.6.
60 706 Defines the cooling factor at zero speed in
relation to the point where the motor is
running at nominal speed without external
cooling.
Varies 707 The time constant is the time within which
the calculated thermal stage has reached
63% of its final value.
100 708 Motor thermal loadability states how much
the motor can be thermally loaded.
