Name Description
Possible Causes & Corrective Action
Setup Fault 6
This fault is declared if the
multi-step speed references
have exceeded a defined limit,
which is defined in terms of a
percentage of contract speed
(CONTRACT CAR SPD
parameter).
Check Parameters Settings
 Check SPEED COMMAND1-16 (A3)
parameters, if greater than 150% of
CONTRACT CAR SPD (A1) parameter
 Note: This fault is only declared with SPD
CMD SRC (C1) equals MULTISTEP or SER
MULTISTEP
Setup Fault 7
This fault is declared if the run
logic inputs are defined
incorrectly. You can either
choose group #1 (RUN and
UP/DWN) or group #2 (RUN
UP and RUN DOWN). But you
cannot mix and match or this
fault will be declared.
Check Parameters Settings
Check configurations of logic inputs (C2) – either
RUN & UP/DWN or RUN UP & RUN DOWN
Setup Fault 8
This fault is declared if the DIR
CONFIRM (C1) parameter is
enabled and any of the
following conditions are not
met:
A logic input (C2) must be
assigned to RUN UP.
A logic input (C2) must be
assigned to RUN DOWN.
The SPD COMMAND SRC
(C1) parameter must be set to
ANALOG INPUT
... Confirms proper set-up of
Analog Speed Command
direction confirm function
Check Parameters Settings:
 Check configurations of logic inputs (C2) for
two logic input defined as RUN UP & RUN
DOWN
 Verify SPD COMMAND SRC (C1) is set to
ANALOG INPUT
 If nuisance fault and not using Up-Down
Confirm, function disabled by setting the DIR
CONFIRM (C1) parameter to DISABLED
Sft Cn Opened
Safety Chain is open and motor
contactor power was not
available when the drive was
commanded to start.
Contactor power sense on
TB1-2 is opened for 20mS
when the regulator release is
active and the speed reference
is greater than 20% of contract
speed.
Contactor Problem
 Check motor contactor power
 Verify safety chain was closed
Parameter Settings
 Verify C2 Logic Inputs contains setting CTR
PWR SENSE
Hardware problem
 Verify wiring to A6TB1-2, this input is on if the
contactor power is on.
If the above point is not on, check at A8TB4-1 &
A8TB4-4, this is the input for the 120 or 240Vac
control power.
 Verify that the correct A8 PCB is installed,
46S04174-0010 works with the 240V Safety
chain power and the -0020 works with the
120V Safety chain power.
