Protections (M3.9)
Protections define the way the drive is to respond to conditions that can occur in the drive.
Table 46: Protections Settings.
Structure Parameter Unit Min Max Default ID Description
P3.9.1 AI Low Fault No Action Fault, Coast No Action 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 (stop according to stop mode)
4 = Fault (stop by coasting)
P3.9.2 External Fault No Action Fault, Coast 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
(stop according to stop mode)
3 = Fault (stop by coasting)
P3.9.3 InputPhaseFault 3-phase 1-phase 3-phase 730 Defines the input phase support.
0 = 3-phase support
1 = 1-phase support
NOTE
: If single phase supply is used, 1-
phase support must be selected.
P3.9.4 Undervoltage Flt Fault Stored No History Fault Stored 727 Defines if the under-voltage fault is stored
in the fault history or not.
0 = Fault Stored
1 = No History
P3.9.5 OutputPhase Flt No Action Fault, Coast Fault 702 Defines the response to an output phase
loss. Response settings are as follows:
0 = No Action
1 = Alarm
2 = Fault
(stop according to stop mode)
3 = Fault (stop by coasting)
P3.9.6 Motor Therm Prot No Action Fault, Coast Fault 704 Defines the response to a motor thermal
protection. Response settings are as
follows:
0 = No Action
1 = Alarm
2 = Fault (stop according to stop mode)
3 = Fault (stop by coasting)
P3.9.7 MotAmbient Temp ºF -4 212 104 705 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.
P3.9.8 ZeroSpeedCooling % 5 150 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.
P3.9.9 ThermTimeConst min 1 200 Varies 707 The time constant is the time within which
the calculated thermal stage has reached
63% of its final value.
P3.9.10 MotThermLoadbil % 0 150 100 708 Motor thermal loadability states how much
the motor can be thermally loaded.
