When ALT is shown, the inverter is in the following condition(s).
You can see the status of ALT by pressing UP key on the three-lined monitor or on [dC-38].
When RETRY is shown, the inverter is in the following condition(s).
You can see the status of RETRY by pressing UP key on the three-lined monitor or on [dC-39].
Icon 2 ALT
Occurrence
Estimated cause(s)
Exemplar measures to be taken
Output current was
high, and [dC-38]
ALT was set to 01.
The current increased due to load or other fac-
tors, exceeding the overload prewarning levels
set in [CE106] or the similar parameter.
• Remove the factor for the increased
load.
(E.g., by cleaning a clogged channel)
• Enable overload limit function or sim-
ilar function.
Output current was
high, and [dC-38]
ALT was set to 02.
The electronic thermal function of motor was
activated due to increase in current and the load
exceeded the electronic thermal warning level
(MTR) set in [CE-30].
• Remove the factor for the increased
load.
(E.g., by cleaning a clogged channel)
• Re-examine the electric thermal set-
tings or the similar parameter.
Output current was
high, and [dC-38]
ALT was set to 03.
The electronic thermal function of inverter was
activated due to increase in current and the load
exceeded the electronic thermal warning level
(CTL) set in [CE-31].
Remove the factor for the increased
load.
(E.g., by cleaning a clogged channel)
Icon 2 RETRY
Occurrence
Estimated cause(s)
Exemplar measures to be taken
Output was turned
OFF and [dC-39]
RETRY was set to
01.
The inverter is in the waiting mode after a trip
retry operation due to increased current or P-N
voltage fluctuation.
• If the wait time become longer, the
following delay time become shorter.
[bb-26] [bb-29] [bb-31]
• If this error is generated consecu-
tively, make the wait time longer.
[bb-26] [bb-29] [bb-31]
Output was turned
OFF and [dC-39]
RETRY was set to
02.
The inverter is in the waiting mode before
restart after power-off by [RS], [FRS], or [CS]
terminal.
If the wait time become longer, the fol-
lowing delay time become shorter.
[bb-26]
