Fault Legend Description
175F9 95737 30201 Alm:DC Bs Ovrvlt OV – Overvoltage. Detection levels:
400VDC for 230V rated unit;
800VDC for 460V rated unit;
1050VDC for 600V rated unit. Yes Yes Yes Minor Minor Check input AC supply. Possibility
of erroneous operation due to noise:
remove noise source by connecting
surge suppressor to relay and
magnetic contactor coils; provide line
filter to remove noise on input power
line. Note: The input labeled ‘Minor’
is declared only if drive is NOT in
Run mode and only if this is
programmed as an ALARM.
175FA 95738 30202 Alm:Htsnk Ovrtmp OH – Cooling fin overheat.
Heatsink fin temperature exceeded
preset value found in inverter
parameter L8-02. Yes Yes Yes Minor Minor Alarm declared only if inverter
parameter L8-03 = 3. Reduce
ambient temperature to less than
45˚C (113˚ F). Clean heat sink.
Replace cooling fan if necessary.
175FB 95739 30203 Alm: Over Heat 2 OH2 – External detection of
heatsink overtemp. One of H1-01
through H1-06 is programmed for
this alarm and that terminal input is
closed. Yes Yes Yes Minor Minor Reduce ambient temperature to less
than 45˚C (113˚ F). Clean heat sink.
Replace cooling fan if necessary
175FC 95740 30204 Alm:Ovrtrq Det 1 OL3 – Overtorque detect 1 alarm.
Output torque exceeded the
Overtorque Detection Level 1 set in
L6-02 for vector control. 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.
