Sub codes can be checked by the error sub code (3011Hex-04Hex). Individual alarms occur in addi-
tion to the following alarms when regular alarm detection is activated.

Error sub
code
0007 Hex When RUN command OFF, forced stop "STOP" and free-run stop
0008 Hex "FRS," etc. are input during tuning
0009 Hex →Do not turn the RUN command OFF during tuning.
When an abnormally large current flows during tuning
0006 Hex
→Check the state of the mechanical brake. Also, check if the motor
000A Hex
can be mechanically rotated.
0001 Hex When unbalance between phases or an output phase loss is detected,
0002 Hex or when an open output, etc. causes the tuning result to be an abnor-
0003 Hex mally large or small value
0004 Hex →Check the wiring.
When various limit operations occur during tuning, or when a limit is
applied at the maximum output frequency or frequency limiter (upper
000D Hex limit)
→Change so that the limit value becomes 50% or higher of the base
frequency.
When an insufficient voltage state has occurred or an alarm has occur-
red
000F Hex
→For details on countermeasures for individual alarms, refer to
9-1 Alarm Display and Remedies on page 9-2.
When 3x the set value of acceleration time in 3004Hex-08Hex is ex-
ceeded for the output frequency to reach 50% of the base frequency
0012 Hex
→Increase the value of 3004Hex-08Hex.
Although the motor is rotated for magnetic pole position tuning when
3007Hex-1FHex = 0 or 3, when 3007Hex-05Hex = 1: Tune the motor
parameters while stopped is performed at this setting
0015 Hex
When 3007Hex-05Hex = 5: Tune the motor parameters while stopped
is performed when 3004Hex-2BHex = 15
→Set to the correct combination.
When the rated impedance or rated inductance is outside the effective
range
138B Hex
→Check setting of 3004Hex-05Hex, 3004Hex-06Hex and
3007Hex-04Hex.
When 3007Hex-1FHex = 1 or 3 is set: When the salient pole ratio of
the motor inductance is small
When 3007Hex-1FHex = 2 is set: When there is no magnetic satura-
tion characteristic of the motor
→When 3007Hex-1FHex = 1, change 3007Hex-58Hex to a small val-
138D Hex
ue. Note, however, that in the case of motors that are difficult to mag-
netically saturate, tuning is sometimes impossible.
→When 3007Hex-1FHex = 2 or 3, set 3007Hex-1FHex = 0, and adjust
while increasing 3004Hex-19Hex in stages in increments between
about 0.5 to 5.0 s until rotation tuning no longer fails.
