LED display Description Cause Possible solutions
EF4
(flash)
External fault
(S4)
External fault (Terminal S4)
Active when 03-03= 25 or 68,
and Inverter external fault
selection 08-24=2.
 Multifunction digital input
external fault active and
parameter 08-24 = 2 for
operation to continue.
 Multi-function input
function set incorrectly.
 Check wiring
 Multi-function input
function set incorrectly.
 Check wiring
EF5
(flash)
External fault
(S5)
External fault (Terminal S5)
Active when 03-04= 25 or 68,
and Inverter external fault
selection 08-24=2.
EF6
(flash)
External fault
(S6)
External fault (Terminal S6)
Active when 03-05= 25 or 68,
and Inverter external fault
selection 08-24=2.
EF9
(flash)
error of
forward/reversal
rotation
Forward run and reverse run
are active within 0.5 sec of
each other. Stop method set
by parameter 07-09.
 Forward run and reverse run
active (see 2-wire control).
 Check run command
wiring
SE01
Rang setting
error
Parameter setting falls
outside the allowed range.
 Some parameter ranges are
determined by other inverter
parameters which could
cause an out of range
warning when the
dependency parameter is
adjusted. For example:
02-00>02-01, 00-12<00-13
or when 00-07 = 1, 00-05 is
the same with 00-06 or
20-16 <= 20-15.
 Check parameter setting.
SE02
Digital input
terminal error
Multi-function input setting
error.
 Multi-function digital input
terminals (03-00 to 03-07)
are set to the same function
(not including ext. fault and
not used.) or UP/DOWN
commands are not set at
the same time( they must
be used together).
 UP/DOWN commands (08
and 09) and ACC/DEC
commands (11) are set at
the same time.
 Speed search 1(19，
maximum frequency) and
Speed search 2 (34，from
the set frequency）are set at
the same time.
 2-wire sequence and 3-wire
sequence set at the same
time in 03-00~03-07
 Check multi-function input
setting.
