Dynamic brake open circuit
detection test did not run.
The dynamic brake open circuit detection test is not
performed if the short circuit detection test fails.
Dynamic brake voltage
feedback evaluation was not
performed.
The dynamic brake voltage feedback evaluation is
not performed if the short circuit detection test or the
open circuit detection test fails.
The following are descriptions of error messages:
Error Message Description/Procedure
Cell Test invoked in
simulator mode.
The simulator mode variable Simulate mode act is
TRUE. The Bridge Cell Test cannot be run in
simulator mode. Change the simulator mode by
setting request parameter Simulate mode to FALSE
and run the Bridge Cell Test again.
Cell Test did not run to
completion. Cell Test
request was removed.
The Cell Test command was removed during Cell
Test. The user may have aborted the test.
Cell Test did not run to
completion. Internal Cell
Test fault detected.
A drive trip fault occurred during the Bridge Cell
Test. Correct and clear any existing trip faults and
run the Bridge Cell Test again.
Cell Test did not run. Cell
Test cannot be run with
switchgear closed.
Press the "SWITCHGEAR OPEN" button on the
drive. Wait for the DC bus voltage to completely
discharge. Run the Bridge Cell Test again.
Cell Test did not run to
completion. Motor was not at
zero speed.
The Bridge Cell Test cannot be run if the motor is
not at zero speed. Wait for the motor to stop and run
the Bridge Cell Test again.
Cell Test did not run to
completion. DC bus could
not be charged.
The Bridge Cell Test was unable to charge the DC
bus. Following are some of the possible problems
which may exist in the drive:
Defective static charger
Shorted DC bus (POS to NEG)
Incorrect DC voltage feedbacks
Cell Test did not run to
completion. DC bus could
not be balanced.
The Bridge Cell Test was unable to balance the DC
bus. Following are some of the possible problems
which may exist in the drive:
Shorted DC bus (POS to NEU or NEG to NEU)
Incorrect DC voltage feedbacks
Shorted DBS1 or DBS2 IGBTs (if the drive includes
the dynamic brake option).
Cell Test did not run to
completion. Motor current
did not decay.
The Bridge Cell Test detected motor current 1
second after the last pulse was completed.
DAC Setup
The DAC Setup wizard directs configuration of the analog outputs (DACs). For more
information on the DACs, see the Analog Inputs/Outputs and Mapping function help.
