1336 SPIDER 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 ille-
gal frequency reference to the drive.
Auxiliary Fault
02 The auxiliary input interlock is
open. Check connections at TB4-TB6 and
[Input Mode] setting.
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 Run
Reverse commands attempt
direction control, but bi-polar input
is not masked from direction con-
trol.
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 Internally monitored fault condi-
tion with a number of possible
causes. 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 programming of [Cur Lim Trip
En] parameter. Check for excess load,
improper DC boost setting, DC brake
volts set too high or other causes of
excess current.
Drive -> HIM Refer to Table 8.B.
DSP Comm Fault
27 Refer to the “Description” and “Action” statements for C167 Watchdog
(F17) above.
DSP Protected
46 Flash download included a new
DSP Main Block and J14 was not
installed when power was
restored. Remove power from the drive. Install
J14 per download kit instructions and
reapply power. When transfer is com-
plete, remove power and J14.
DSP Queue Fault
31 Refer to the “Description” and “Action” statements for C167 Watchdog
(F17) above.
DSP Reset Fault
22 Power-up has been attempted
with an Open Stop contact or
Closed Start contact. Check/verify wiring and contact oper-
ation.
DSP Timeout Fault
28 Refer to the “Description” and “Action” statements for C167 Watchdog
(F17) above.
EE Init Read
53 1. Gate Drive Bd. replacement
(requires re-initialization).
2. Trouble reading EEPROM dur-
ing initialization.
1. Reset to factory defaults (refer to
page A–12) & cycle input power.
2. Check all connections to Power/
Driver Board. Replace board or
complete drive as needed.
EE Init Value
54 Stored parameter value out of
range on initialization. 1. Reset to factory defaults (refer to
page A–12) & cycle input power.
2. Check all connections to the Power/
Driver Bd. Replace the board or
complete drive as needed.
