441 Load Loss Action
Load Loss Action
Configures the action to take when the load is less than or equal to P442 [Load Loss
Level] for the amount of time set in P443 [Load Loss Time].
“Ignore” (0) – No action is taken.
“Alarm” (1) – Type 1 alarm indicated.
“Flt Minor” (2) – Minor fault indicated. If running, drive continues to run. Enable with
P950 [Minor Flt Cfg]. If not enabled, acts like a major fault.
“FltCoastStop” (3) – Major fault indicated. Coast to Stop.
“Flt RampStop” (4) – Major fault indicated. Ramp to Stop.
“Flt CL Stop” (5) – Major fault indicated. Current Limit Stop. Default:
Options: 0 = “Ignore”
0 = “Ignore”
1 = “Alarm”
2 = “Flt Minor”
3 = “FltCoastStop”
4 = “Flt RampStop”
5 = “Flt CL Stop” RW 32-bit
Integer
442 Load Loss Level
Load Loss Level
Sets the percentage of motor nameplate torque (absolute value) associated with
activation of the load loss function, P441 [Load Loss Action].
See P5 [Torque Cur Fdbk] motor nameplate torque. Units:
Default:
Min/Max: %
200.00
0.00 / 800.00 RW Real
443 Load Loss Time
Load Loss Time
Sets the time associated with activation of the load loss function (see P441 [Load Loss
Action]). Units:
Default:
Min/Max: Secs
0.00
0.00 / 300.00 RW Real
444 OutPhaseLossActn
Output Phase Loss Action
Selects action to take if output phase loss is detected.
“Ignore” (0) – No action is taken.
“Alarm” (1) – Type 1 alarm indicated.
“Flt Minor” (2) – Minor fault indicated. If running, drive continues to run.
Enable with P950 [Minor Flt Cfg]. If not enabled, acts like a major fault.
“FltCoastStop” (3) – Major fault indicated. Coast to Stop.
“Flt RampStop” (4) – Major fault indicated. Ramp to Stop.
“Flt CL Stop” (5) – Major fault indicated. Current Limit Stop. Default:
Options: 0 = “Ignore”
0 = “Ignore”
1 = “Alarm”
2 = “Flt Minor”
3 = “FltCoastStop”
4 = “Flt RampStop”
5 = “Flt CL Stop” RW 32-bit
Integer
445 Out PhaseLossLvl
Output Phase Loss Level
Sets the threshold level which is used to determine an output phase loss condition.
Each motor phase must exceed this value. Decreasing this parameter’s value lowers
sensitivity. Default:
Min/Max:. 200
0 / 1000 RW 32-bit
