5) Auto tuning error message
LCD Display Description and Solution
Displayed when phase loss of A or B occurs and/or error
between reference speed and encoder feedback speed
exceeds motor rated slip. Check whether wiring of
encoder power (PE, GE) and A/B phase is conducted
correctly.
Displayed in case of reverse wiring of phase A/B or U, V,
W. Wire the U, V, W in a correct order or change the
encoder direction setting to “ B Phase Lead ” in PAR_11.
Displayed when RS value is greater than 5[
Ω
] or less
than 0.002[
Ω
]. Check for wiring of inverter and motor
and motor damage. It may occur when motor rating is
much lower than that of inverter.
Displayed when sL is higher than 100[mH]. Check for
wiring of inverter and motor and motor damage.
Displayed when motor rpm exceeds 1650 rpm (1800 rpm
rated motor) during flux current calculation or flux
current is not measured for a long time. Check for wiring
of inverter and motor and number of motor phase.
Displayed when motor rpm exceeds 1650 rpm (1800 rpm
rated motor) during Ls calculation or Ls is not measured
for a long time. Check for wiring of inverter and motor
and number of motor phase.
Displayed when initial set value of PAR_27 is set too high.
Repeat the calculation after lowering 30% to initial
value.
Displayed when initial set value of PAR_27 is set too low.
Repeat the calculation after increasing 30% to initial
value.
6) Input voltage setting
PAR_23 ’ s voltage is used for referenced value to occur the low voltage error through the calculation as below.

dc
: Low voltage error is released above condition of PAR_23 ’ s voltage.
Difference of voltage ripple in DC part will be bigger when the output of inverter is bigger in an open-phase of inverter.
Then, input voltage is lower, low voltage trip is occurred by the minimum limit of ripple. Set the real input voltage to
prevent low voltage and occurring the Input open-phase error. Set value of LVT level in PAR_23 is 180Vdc in a range of
above 180V in 200V class and 360Vdc in a range of above 342V in 400V class.
