CODE

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.

– See associated Fault Description
