Description
Range
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
0.0 to
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.
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)
0.0 to
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.
Operation restarts at a speed
obtained by multiplying the
speed from the speed search by
the compensation gain (excita-
tion search only.) 1.00 to
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.
On speed calculation, the
search method is automatically
0.5 to
switched according to the
100.0
motor residential voltage. Set
the switching level.
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 0.5 to
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.
Sets primary lag of the torque
compensation function during
speed search in units of milli- 10000
seconds.
