Description
P3.9.10
MotThermLoadbil
%
0
150
100
708
Motor thermal loadability states how
much the motor can be thermally loaded.
P3.9.11
MotorStall Flt
0
3
0
709
Defines the response to a motor stall.
Response settings are as follows:
0 = No Action
1 = Alarm
2 = Fault (stop according to stop mode)
3 = Fault (stop by coasting)
P3.9.12
Stall Current
A
0
2*IH
IH
710
For a stall stage to occur, the current
must have exceeded this limit.
P3.9.13
Stall Time Limit
s
1
120
15
711
This is the maximum time allowed for a
stall stage.
P3.9.14
Stall Freq.Limit
Hz
1
Parameter
P1.9 or
P3.3.2
25
712
For a stall stage to occur, the output
frequency must have remained below this
limit for a certain time.
P3.9.15
Underload Flt
0
3
0
713
Defines the response to an underload.
Response settings are as follows:
0 = No Action
1 = Alarm
2 = Fault (stop according to stop mode)
3 = Fault (stop by coasting)
P3.9.16
UL FieldweakLoad
%
10
150
50
714
This parameter gives the value for the
min torque allowed when the output
frequency is above the field weakening
point.
P3.9.17
UL ZeroFreq.Load
%
5
150
10
715
This parameter gives the value for the
min torque allowed with zero frequency.
P3.9.18
UL Time Limit
s
2
600
20
716
This is the maximum time allowed for an
underload state to exist.
P3.9.19
FieldbusComm Flt
No Action
4
Fault
733
Defines the response to a fieldbus
communications signal loss. 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)
P3.9.20
SlotComm Flt
No Action
Fault, Coast
Fault
734
Defines the response to an option card
slot communications failure. Response
settings are as follows:
0 = No Action
1 = Alarm
2 = Fault (stop according to stop mode)
3 = Fault (stop by coasting)
P3.9.21
Thermistor Fault
No Action
Fault, Coast
No Action
732
Defines the response to a thermistor
failure. Response settings are as follows:
0 = No Action
1 = Alarm
2 = Fault (stop according to stop mode)
3 = Fault (stop by coasting)
NOTE : It is recommend to set to a value
of Fault (according to stop mode) if a
BT300-OPT-B4-V option card is installed.
