FAULT
MESSAGE
FAULT
CODE
DESCRIPTION RECOMMENDED ACTIONS
DPI Interface 243 This fault typically occurs when you have
the Communication Type (P147) set for
500k (DPI only), and you have a SCANPort
adapter connected to the CIB. SCANPort
operates at 125k, and the DPI can operate
at both speeds. This can also occur if the
SCANPort network attempts to access Port
5, which is internally assigned to DPI.
Note: „MOD A‟ LED on the CIB indicates a
healthy SCANPort Adapter when Green.
„MOD B‟ LED on the CIB indicates a healthy
DPI Adapter when Green.
– Ensure Communication Type is set for
125k for any drive with SCANPort
connections
– Ensure you are not using a SCANPort
splitter with Port 5 active as the drive
internally has assigned Port 5 to DPI,
and this conflict will create a fault
– Cycle power to ensure you
Communication Type change takes
effect
– The final cause could be a CIB Hardware
problem, and the board should be
replaced if the above actions are
unsuccessful
DI Contactor 18 The Drive Input Contactor has opened
without command from the PF7000 drive. – The drive system needs to have
complete control over all contactors, so
investigation of the specific contactor
fault is required
– Verify contactor feedback
– Verify the control power circuit for the
contactor
– Check permissive string to the contactor
control relay (refer to drawing) -Check
contactor/breaker for physical
malfunction (auxiliaries)
– Check SCB inputs and outputs
DO Contactor 19 The Drive Output Contactor has opened
without command from the PF7000 drive.
OP Contactor 34 The system output contactor has opened
without command from the PF7000 drive.
BP Contactor 20 The Bypass Contactor has opened without
command from the PF7000 drive.
DI Iso Switch 29 The Drive Input Isolation Switch is in the
opposite state than expected, or the state
has changed during operation. – Depending on the mode of operation
(Normal, System Test, Open-Circuit
Test, DC Current Test, or Open-Loop),
there are specific states for all the
possible system isolation switches (Refer
to the description of the Parameter 192 –
IsolSw/Ctctr Cfg in the parameters
manual)
– Ensure the isolation switches are in the
proper position
– Verify wiring feedback
– Verify isolation switch mechanical
auxiliary setup
DO Iso Switch 30 The Drive Output Isolation Switch is in the
opposite state than expected, or the state
has changed during operation.
OP Iso Switch 32 The System Output Isolation Switch is in the
opposite state than expected, or the state
has changed during operation.
BP Iso Switch 31 The Bypass Isolation Switch is in the
opposite state than expected, or the state
has changed during operation.
Drive OL 191 A Drive Overload condition has been
detected, where the overload condition is
calculated using DC Current Feedback
(P322) and an algorithm based on Drive
Overload Trip (P163) as the absolute trip
level, Drive Overload Delay (P164) as the
base trip delay, and Drive Overload Min
(P269) as initial detection level.
– Transient Loading – Check torque limit
and overload settings and compare
loading to torque settings and trip
settings
– Open Burden Resistor – Check Current
feedback and check the burden resistors
Dvc AK/Snubb 195 Device Anode-Cathode or Snubber fault – NOT USED IN 5.xxxx
External 1-16 1-16 These are the optional additional External
Faults available when there is an additional
XIO board installed. This is configured with
XIO Ext Faults (P593), and this message
– Review XIO Board Drawing:
– Identify source of Input from External
Fault XIO Board print and investigate the
cause of the fault
