1336 PLUS 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 connections at
TB3-24. If option is not installed,
set [Input Mode] to “1.”
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
complete drive as required.
Blwn Fuse Flt
58 If the difference between the
commanded voltage and the
measured voltage is greater
than 1/8 of rated voltage for
0.5 seconds, then a fault will
be issued indicating that the
bus fuse has blown. Locate cause, replace fuse.
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 Fault Reset
22 Power-up has been attempted
with an Open Stop contact or
Closed Start contact. Check/verify wiring and contact
operation.
Drive –> HIM Error 1 – The checksum read
from the EEPROM does not
match the checksum
calculated from the EEPROM
data. Repeat operation. Replace HIM.
EE Init Read
53 1. Gate Drive Board replace-
ment (requires re-initializa-
tion).
2. Trouble reading EEPROM
during initialization.
1. Reset to factory defaults &
reset fault.
2. Check all connections to Pow-
er/ Driver Board. Replace
board or complete drive as
needed.
EE Init Value
54 Stored parameter value out of
range on initialization. Check all connections to the
Power/Driver Board. Replace the
board or complete drive as
needed.
EEprom Checksum
66 The checksum read from the
EEPROM does not match the
checksum calculated from the
EEPROM data. Check all wire and cable connec-
tions to the Power Driver Board.
Replace Power Driver Board or
complete drive as required.
EEprom Fault
32 EEPROM is being
programmed and will not write
a new value. Check all wire and cable connec-
tions to the Main Control Board.
Replace Main Control Board or
complete drive as required.
FGND 10ms Over
52 Microprocessor loop fault.
Occurs if a 10ms interrupt is
pending before the current
interrupt is complete. Replace Main Control Board or
complete drive as required.
