Fault Legend Description
1760B 95755 30219 Alm:Memobus
Comm CE – Communication fault. Control
data was not received for 2 seconds
after initial communication. Yes Yes Yes Minor Minor This is a serial communications error.
If h5-05=1, then the alarm bit will be
set if no serial communication is seen
AND h5-04= 3. Check validity of
Smart Trac AC1 CPU card firmware
and application program.
1760C 95756 30220 Alm:Mtr Overlded OL1 – Motor overload. Protects the
motor. Motor thermal overload
protection has tripped. Inverter
parameter L1-02 has been exceeded
(initial value: 150% for 60 sec.). Yes Yes Yes Minor Minor Alarm is declared if thermal overload
exceeds 90% of fault detection level
AND L1-01= 1. Load may be too
large. Check drive capacity (inverter
parameter o2-04) for correct factory
setting. Check for proper setting of
electronic thermal overload setting:
inverter parameters E1-02, E2-01,
L1-02. Try disconnecting motor
wiring from output terminals – if OL
is still indicated, problem may be due
to noise or faulty inverter cards
