DESCRIPTION
RECOMMENDED ACTIONS
DI IsoSw Open
42
The Drive Input Isolation Switch is Open
when it is expected to be closed, which is in
Normal mode, DC Current test mode, Open
Loop test mode, and Open Circuit test
mode,
– In DC Current test modes, the isolation
switches are expected to be closed for
DC Current test; although only the input
contactor is required the test will run with
warnings if the switches are open
– Ensure the isolation switches are in the
proper position for the specific operating
mode (Refer to the description of the
Parameter 192 – IsolSw /Ctctr Cfg in the
parameters manual)
– Verify wiring feedback
– Verify isolation switch mechanical
auxiliary setup
DI IsoSw Clsd
324
The Drive Input Isolation Switch is Closed
when it is expected to be open, which is in
System Test mode and Gating Test mode.
DO IsoSw Open
43
The Drive Output Isolation Switch is Open
when it is expected to be closed, which is in
Normal mode, DC Current test mode, and
Open Loop test mode.
DO IsoSw Clsd
325
The Drive Output Isolation Switch is Closed
when it is expected to be open, which is in
Open Circuit mode, System Test mode and
Gating Test mode
OP IsoSw Open
45
The System Output Isolation Switch is Open
when it is expected to be closed, which is in
Normal mode, DC Current test mode, and
Open Loop test mode.
OP IsoSw Clsd
326
The System Output Isolation Switch is
Closed when it is expected to be open,
which is in Open Circuit mode, System Test
mode and Gating Test mode
BP IsoSw Open
44
The Bypass Isolation Switch is Open when it
is expected to be closed, which is in Normal
mode, DC Current test mode, and Open
Loop test mode.
BP IsoSw Clsd
327
The Bypass Isolation Switch is Closed when
it is expected to be open, which is in Open
Circuit mode, System Test mode and Gating
Test mode
DC/DC Redundant
101
The main outputs of the DC/DC power
supply (+5VDC,
15VDC) have failed, but
the redundant outputs are still active. This
is set at 95% of rated value for 15VDC
outputs, and 5.00VDC for 5.3VDC output.
– Redundant Supply is paralleled, so there
is no way to confirm output voltage level
– Verify the output from the alarm signal is
wired correctly
– Replace Power Supply when possible
DC Link OT
67
The thermal switch in the drive DC Link
Reactor has detected an over-temperature
and has opened, but was set up as a
warning.. There is a thermal switch in each
DC Link winding, and they are connected in
series.
– See associated Fault Description
DC Link OC
115
The measured IDC Link Feedback (P322)
has exceeded DC Overcurrent Trip (P169),
and instantaneously causes a warning.
