Output phase loss detection can be used to detect a disconnected motor phase or a failed power device if
Output Phase Loss Detection Enable
(06.059) is set to a non-zero value.
0: Disabled
Output phase loss detection is not active.
1: Phases
A test is carried out each time the drive is enabled to run to check if all three phases are connected. If the test fails a
Out Phase Loss
.X trip is initiated
where X indicates which phase is not connected (1 = U, 2 = V, 3 = W). It should be noted that this test is not carried out in Open-loop mode if "catch a
spinning motor" is enabled (i.e.
Catch A Spinning Motor
(06.009) > 0). A test is also carried out while the drive is running. If the drive output frequency is
above 4Hz and a phase is disconnected for the time specified by
Output Phase Loss Detection Time
(06.058) then a
Out Phase Loss
.4 trip is initiated. It
should be noted that if the motor is operating at high speed and flux weakening is active so that the magnetising current is below half the rated level then
output phase loss will not be detected. If the motor is heavily loaded when a phase is disconnected it is likely that the motor will stall and the drive output
frequency may fall below 4Hz before output phase loss is detected.
2: Devices
This test is similar to the "Phases" test above except that additional tests are carried out when the drive is enabled to run which can detect if a either the
positive or negative power device has failed in each phase. If a phase is disconnected or the positive power device has failed then a
Out Phase Loss
.X
trip is initiated where X is between 1 and 3 and indicates the phase that is not connected or has a failed positive device (1 = U, 2 = V, 3 = W). If X is
