TEXT

D-Axis Inductance at 0 Pct OutOfRange.

Parameter 10:910 [Autotune] is set to 3

'Rotate MtrID' and the value measured by

Ld00 Fail

the Autotune procedure for parameter

10:627 [u PM Ld at 0] is not in the range

of acceptable values (negative).

D-Axis Inductance at 100 Pct

OutOfRange. Parameter 10:910

[Autotune] is set to 3 'Rotate MtrID' and

Ld100 Fail

the value measured by the Autotune

procedure for parameter 10:629 [u PM Ld

at 100] is not in the range of acceptable

values (negative).

Q-Axis Inductance Out of Range.

Parameter 10:910 [Autotune] is set to 3

'Rotate MtrID' and the value measured by

the Autotune procedure for parameter

10:637 [u PM Lq at 25], 10:639 [u PM Lq

at 50], 10:641 [u PM Lq at 75], 10:643 [u

Lq Fail

PM Lq at 100], 10:645 [u PM Lq at 125],

10:647 [u PM Lq at 150], 10:649 [u PM Lq

at 175], or 10:651 [u PM Lq at 200] is not

in the range of acceptable values. This

could happen if current fails to rise up or

decreases too fast due to abnormal

conditions.

Image Watchdog Fault. Communication

between the main control board and the

image buffer in one of the power

peripherals (power layer interface board,

torque accuracy module, or DC

precharge board) has stopped

transmitting for 10 milliseconds.

Constants Message Invalid Fault. The

constants header information did not

match the content of the power peripheral

(power layer interface board, torque

accuracy module, or DC precharge

board).

Constants Checksum Fault. The

constants download failed the checksum

test by one of the power peripherals

(power layer interface board, torque

accuracy module, or DC precharge

board).

Nonvolatile Data Checksum Fault.

Checksum test failed for non-volatile data

for the DC precharge board.

Power Supply Undervoltage. An

undervoltage event occurred in the local

(internal to the PIB) power supply. A

possible cause is the DC bus voltage,

which feeds the power supply, has

dropped below 400-v DC. This power

supply provides power to the power layer

interface board or DC precharge board (if

present).

Precharge Fault. Main control board

firmware did not indicate that bus voltage

was good within the specified time period

following closure of the precharge

contactor.

•

MCS Failed to Close or Wiring Bay

Overtemp. Two conditions can cause

this fault:

•

Condition 1: The molded case switch

(MCS) in the DC precharge has failed

to close when commanded.

•

Condition 2: The temperature in the

input bay or entry wiring bay has risen

too high. This condition can only

cause the fault before the drive or bus

supply has completed precharge.

ACTION

Verify motor nameplate data and rerun

the rotate motor ID test. If fault

continues, obtain the motor datasheet

from motor vendor.

from motor vendor.

continues, obtain the motor datasheet

from motor vendor.

Power down and then check the fiber-

optic communication connections.

Cycle power.

Cycle power. If the fault persists,

replace the DC precharge board. See

the hardware service manual,

publication 750-TG100 for PowerFlex

755T or publication 750-TG101 for

PowerFlex 755TS products, for the

replacement procedure.

Verify DC bus is present on the Mn

power module via the hardware

testpoints. If so, replace the Mn power

interface board (PIB). See hardware

service manual, publication 750-TG100

for PowerFlex 755T or publication 750-

TG101 for PowerFlex 755TS products,

for the replacement procedure.

Check the timing of the rise of the DC

bus following precharge.

•

Condition 1: Inspect the DC

precharge module and the thermal

sensor harness for the exit wiring

bay. Ensure MCS lockout device is

not closed. See the Service

Manual, publication 750-TG100 for

PowerFlex 755T or publication

750-TG101 for PowerFlex 755TS

products, for details.

•

Condition 2: Check the enclosure

filters and fans. Problems with the

baffling between these bay and

adjacent bays can be sources of

heat.

FAULT ACTION
