PLUS II Fault Descriptions
Name & Fault # Description Action
Adptr Freq Err
65 The SCANport adapter that was
the selected frequency reference
sent a frequency greater than
32767 to the drive. Correct the problem that is causing
the SCANport adapter to send the
illegal frequency reference to the
drive.
Auxiliary Fault
02 The auxiliary input interlock is
open. If Control Interface option is installed,
check TB3 connections. If not
installed, set [Input Mode] to “Status.”
Bgnd 10ms Over
51 Microprocessor loop fault. Occurs
if the 10ms background task
hasn’t been run in 15 ms. Replace Main Control Board or com-
plete drive as required.
Bipolar Dir Flt
16 3 Wire – Bi-polar input is the
active frequency reference and
direction control is not possible.
2 Wire – Run Forward or Reverse
commands attempt direction con-
trol, but bi-polar input is not
masked from direction control.
a) Mask out direction control at bit 7
of [Direction Mask]. b) Remove or
mask other direction control sources.
Set bit 7 of [Direction Mask] to zero.
Blwn Fuse Flt
58 If the difference between the com-
manded voltage and the mea-
sured voltage is greater than 1/8
of rated voltage for 0.5 seconds,
then a fault will be issued indicat-
ing that the bus fuse in 30 kW
(40HP) & up drives has blown. Locate cause, replace fuse.
C167 Watchdog
17 Internal microprocessor fault. If there is only one occurrence, reset
the fault and continue. If the fault con-
tinuously or frequently reoccurs, con-
tact your local service representative
or replace the Main Control Board.
Diag C Lim Flt
36 The drive output current has
exceeded the hardware current
limit and the [Cur Lim Trip En]
parameter was enabled. Check [Cur Lim Trip En]. Check for
excess load, improper DC boost set-
ting, DC brake volts set too high or
other causes of excess current.
Drive -> HIM Refer to Table 7.B .
