has been set to a value different
from 0.
• b5-15 (PI Sleep Function Opera-
tion Level) has been set to a value
different from 0.

V/f Parameter Setting Error
Parameters E1-04, E1-06, E1-07, E1-
09 and E1-11 do not satisfy the fol-
lowing conditions:
• E1-04 (FMAX) ≥ E1-11 (FMID2)
> E1-06 (FA) > E1-07 (FB) ≥ E1-
09 (FMIN)
• Check the parameter
settings of E1-
• A frequency/voltage
value might be set
higher than the maxi-
mum frequency/volt-
age.

and C6-03 (Carrier Frequency
Upper Limit) < C6-04 (Carrier Fre-
quency Lower Limit)
• Upper/lower limit error in C6-03
and C6-04.
Check the parameter set-
tings of C6-02 to C6-05.
