Description
Range
Sets the magnetic contactor
operating delay time when
there is a magnetic contactor on
the output side of the Inverter.
0.0 to
When a speed search is per-
formed after recovering from a
momentary power loss, the
search operation is delayed by
the time set here.
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.
