Fault Legend Description
1754B 95563 30027 Output Pha Loss LF – Drive output has open phase. Yes Yes Yes Minor Major Check wiring between inverter and
motor. Note: inverter parameter L8-
07 = 1 enables this fault.
1754C 95564 30028 Not used
1754D 95565 30029 Oper Disconnect OPR – Operator disconnected.
Digital operator has been
disconnected from drive while in
Run mode. Yes Yes Yes Minor Major Reconnect digital operator to inverter
or disable this fault by setting
inverter parameter o2-06 = 0.
1754E 95566 30030 EPROM R/W Err ERR – EPROM write-in fault.
Attempt to write to nonvolatile
memory has failed. Yes Yes Yes Minor Major Cycle power and then attempt to
initialize. If fault persists, Smart Trac
AC1 inverter card is bad.
1754F 95567 30031 Not used
17550 95568 30032 Memobus Com Err CE – Communication fault. Control
data was not received for 2 seconds
after initial communication. Yes Yes Yes Minor Major Check validity of Smart Trac AC1
CPU card firmware and application
program. This fault is declared only
if H5-04= 0, 1 or 2 and H5-05= 1.
17551 95569 30033 Option Com Err BUS – Communication fault.
Communication fault while drive is
set for Run Command and/or
Frequency Reference from Smart
Trac AC1 CPU card. Yes Yes Yes Minor Major Check validity of Smart Trac AC1
CPU card firmware and application
program. Ensure inverter parameters
B1-01, B1-02 = 3. Note: The input
labeled ‘Major’ is set only if inverter
parameter F9-06
≠
3.
