☞ Note: * These values are automatically entered
according to the FU2-30 [Rated motor selection]. The
above values are displayed when FU2-30 is set to 5 (7.5
kW).
l The auto tuning function automatically measures
the motor parameters needed for control selected
in FU2-39[Control mode selection] such as stator
resistance, rotor resistance, leakage inductance,
no-load current and Encoder feedback frequency.
The motor does not rotate during auto tuning so
there is no need to separate the motor from the
system.
l Encoder operating status can be checked.
l The rated current, voltage, efficiency and slip
described in the motor nameplate should be
entered before performing auto tuning. If efficiency
is not indicated on the nameplate, use the preset
value.
l All or selected parameters can be tuned in Auto-
tuning mode.

[Motor rotation mode when set to All, Enc Test, Tr]
1. With PG Option installed: if FU2-40 is set to All,
Stator resistance (Rs), Leakage inductance
(Lsigma), Stator inductance (Ls), No-load current
(Noload-Curr), Speed Encoder status and Rotor
constants (Tr) are calculated.
2. Without PG Option installed: if FU2-40 is set to All,
Stator resistance (Rs), Leakage inductance
(Lsigma), Stator inductance (Ls) and No-load
current (Noload-Curr) are calculated.
3. If FU2-40 is set to Rs + Lsigma, Stator resistance
(Rs), Leakage inductance (Lsigma) are calculated.
4. Either PG Status or Rotor constant (Tr) can be
checked with PG option card installed.
[Motor non-rotation mode when set to Rs + Lsigma]
1. Stator resistance (Rs), Leakage inductance
(Lsigma) can be calculated by setting FU2-40 to
Rs + Lsigma.
2. User should set Stator resistance (Rs), No-load
current (Noload-Curr) and Rotor constants (Tr).
3. To automatically calculate the Stator inductance
(Ls), No-load current (Noload-Curr) and Rotor
constants (Tr), set the motor rotation mode and
FU2-40 to All.
[With PG option card installed]
1. Set EXT -12 to Feed-back.
2. Set EXT -15 to (A + B).
3. If FU2-40 is set to All, Stator resistance (Rs),
Leakage inductance (Lsigma), Stator induc tance
(Ls), No-load current (Noload-Curr), and Rotor
constants (Tr) are calculated.
4. Stator resistance (Rs), Leakage inductance
(Lsigma) can be calculated by setting FU2-40 to Rs
+ Lsigma.
5. User should set the Stator inductance (Ls), No-load
current (Noload-Curr) and Rotor constants (Tr) if
FU2-40 is set to Rs + Lsigma.
[Without PG option card installed]
1. If FU2-40 is set to All, Stator resistance (Rs),
Leakage inductance (Lsigma), Stator inductance
(Ls), No-load current (Noload-Curr) are calculated.
2. If FU2-40 is set to Rs + Lsigma, Stator resistance
(Rs), Leakage inductance (Lsigma) is calculated.
3. User should set the Stator inductance (Ls), No-load
current (Noload-Curr).
