Fault Legend Description
1753A 95546 30010 Motor Overloaded 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 Major Major fault is declared if 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
1753B 95547 30011 Inv Overloaded OL2 – Drive overload. Protects the
Smart Trac AC1 drive. Drive
overload protection has tripped. Yes Yes Yes Minor Major See fault “Motor Overloaded” for
details.
1753C 95548 30012 Overtorque Det 1 OL3 – Overtorque detect 1. Output
current exceeded Overtorque
Detection Level 1 set in inverter
parameter L6-02. Yes Yes Yes Minor Major Declared only if inverter parameter
L6-01= 3 or 4. Reduce load, increase
acceleration time, or increase inverter
parameter setting L6-02.
1753D 95549 30013 Overtorque Det 2 OL4 – Overtorque detect 2. Output
current exceeded Overtorque
Detection Level 2 set in inverter
parameter L6-05. Yes Yes Yes Minor Major Declared only if inverter parameter
L6-04= 3 or 4. Reduce load, increase
acceleration time, or increase inverter
parameter setting L6-05.
1753E 95550 30014 DynBrk Transistr RR – Dynamic braking transistor
failure. Yes Yes Yes Minor Major Replace dynamic braking unit.
