Fault Legend Description
175FD 95741 30205 Alm:Ovrtrq Det 2 OL4 – Overtorque detect 2 alarm.
Output current exceeded Overtorque
Detection Level 2 set in inverter
parameter L6-05. For V/F control,
parameter L6-05 is considered to be
Output Current. Yes Yes Yes Minor Minor The input labeled ‘Minor’ is set only
if L6-01 = 1 or 2. Reduce load,
increase acceleration time, or
increase inverter parameter setting
L6-02.Reduce load, increase
acceleration time, or increase inverter
parameter setting L6-05.
175FE 95742 30206 Alm:External Flt Both FWD and RUN commands are
simultaneously input for 500ms or
longer. Yes Yes Yes Minor Minor Check input wiring to ensure that
FWD and REV are mutually
exclusive.
175FF 95743 30207 Alm: BB Circuit Base Block activated by external
contact into terminal programmed
for base block. Yes Yes Yes Minor Minor Note: Assuming one of the input
terminals is programmed for external
BB and the BB is being asserted by
an external contact, an overspeed or
max overheat of drive will cause
inverter BB of signals to the power
devices. Recycle SmartTrac AC1
power. If problem persists, replace
inverter card.
17600 95744 30208 Alm: Ext Fault 3 EF3 – External fault signal at
terminal 3 of the inverter card. This
can be programmed to be N.O. or
N.C. contact. Yes Yes Yes Minor Minor Fault has occurred in circuits outside
the Smart Trac AC1 inverter card.
Troubleshoot and correct. Alarm
declared only if H1-01 is in the
range of 2Ch to 2Fh.
