High-function General-purpose Inverter RX2 Series User’s Manual
When LIM is shown, the inverter is in the following condition(s).
You can see the status of LIM by pressing UP key on the three-lined monitor or on [dC-37].
Icon 2 LIM
Occurrence
Estimated cause(s)
Exemplar measures to be taken
Output current was
high, and [dC-37]
LIM was set to 01.
[bA120] overcurrent suppression function was
enabled and the current increased due to the
load or other factors.
Remove the factor for the increased
load.
(E.g., by cleaning a clogged channel,
re-examining the load)
The current was increased by the high ratio of
motor rotation during DC braking that was
caused by the selection of [DB] terminal or
[AF101] DC braking.
• Reduce the DC braking force in
[AF105] or [AF108].
• For stopping, set longer time for
[AF106] DC braking delay time at the
time of the stop.
• For retry operation at the start, set
longer delay time according to the
factors.
[bb-26] [bb-29] [bb-31]
[FA-10] acceleration time is too short.
Make the acceleration time longer in
[FA-10].
Output current was
high, and [dC-37]
LIM was set to 02.
[bA122] overload limit function or similar func-
tion was enabled and the current increased due
to the load or other factors.
Remove the factor for the increased
load.
(E.g., by cleaning a clogged channel,
re-examining the load)
[bA122] overload limit function or similar func-
tion was enabled and [FA-10] acceleration time
was too short.
Make the acceleration time longer in
[FA-10].
Error occurred
during deceleration.
[dC-37] LIM was set
to 03.
[bA140] overvoltage suppression function was
enabled and P-N voltage increased due to
regenerative load or the like.
Remove the factor for the increased
regenerative load.
(E.g., by re-examining the state of the
motor being rotated by external force,
and by re-examining the load)
[bA122] overload limit function or similar func-
tion was enabled and [FA-12] deceleration time
was too short.
Make the deceleration time longer in
[FA-12].
Error occurred
during sudden
acceleration. [dC-37]
LIM was set to 03.
[bA140] overvoltage suppression function was
enabled and P-N voltage increased due to
regenerative load or the like.
Remove the factor for the increased
regenerative load.
(E.g., by re-examining the state of the
motor being rotated by external force,
and by re-examining the load)
Output current was
high, and [dC-37]
LIM was set to 04.
[bA110] torque limit function or similar function
was enabled and the current increased due to
the load or other factors.
Remove the factor for the increased
load.
(E.g., by cleaning a clogged channel,
re-examining the load)
[bA110] torque limit function or similar function
was enabled and [FA-10] acceleration time was
too short.
Make the acceleration time longer in
[FA-10].
Error occurred
during operation.
[dC-37] LIM was set
to 05.
The normal limiting was performed according to
the settings of [bA102] upper limiter, [bA103]
lower limiter, and [AG101] and other jump fre-
quencies.
Re-examine the settings of the
upper/lower limiter or jump frequencies
if necessary.
Error occurred
during operation.
[dC-37] LIM was set
to 06.
The frequency command at below the minimum
frequency [Hb130] has been input.
Set the frequency command at the min-
imum frequency or higher in [FA-01].
