Output current 1
during speed search
Sets the output current during
the first half of speed search as
a coefficient to the motor rated
current (E2-01). (Only for exci-
tation search) Increase the set
value if the search speed
becomes extremely slow at the
speed search after the motor
has been base-blocked for a
long time of period such as the
speed search at startup.

Output current 2
during speed search
Sets the output current during
the last half of speed search as a
coefficient to the motor no-load
current (E2-03). The multipli-
cation of motor no-load current
and set coefficient is limited to
the motor rated current (E2-01)
inside the Inverter. (Only for
excitation search) Increase the
set value if the search speed
becomes extremely slow at the
speed search after the motor
has been base-blocked for a
long time of period such as the
speed search at startup.

Speed search detection
compensation gain
(speed calculation)
Operation restarts at a speed
obtained by multiplying the
speed from the speed search by
the compensation gain (excita-
tion search only.)
Increase this setting if overvolt-
ages of cells occur when a
speed search is performed after
a long baseblock, for example,
in searches at startup.

switching level
On speed calculation, the
search method is automatically
switched according to the
motor residential voltage. Set

Current detection
dead-zone width
during speed search
On speed calculation, the motor
speed is calculated from the
detected current value. For cur-
rent detection, the dead-zone
must be set. Set the dead-zone
width using the current detec-
tion resolution as reference
amount. (only for a excitation
search)
Decrease the set value if the
search speed becomes
extremely slow at the speed
search after the motor has been
baseblocked for a long time of
period such as the speed search
at startup.

compensation function during
speed search in units of milli-
seconds.
