Tuning is performed in
the following order
.
• %R1, %X in motor
stopped state
• No-load current and
magnetic saturation
factor in motor ro-
tating state (50% of
base frequency)
• Rated slip in motor
stopped state again
When the motor can
be rotated safely.

When the motor can-
not be rotated. (Ap-
plied only when rota-
tion tuning has been
performed and the wir-
ing length has been
changed)
The tuning result is automatically written to the relevant parameter.
3 Preparing the mechanical system
As preparation for performing rotation tuning, remove machine couplings, and disable safety in-
terlocks.
4 Execution of auto-tuning
1) Set one of 1, 2 or 5 to parameter P04, and press the
key. 1, 2 and 5 blink slowly.

Selection
1: Tune the motor parame-
ters while stopped
0 -
2: Tune the motor parame-
ters while rotating
5: Tune the motor %R1 and
%X while stopped
2) Input the RUN command. In the factory default state, forward rotation is performed when
the key is pressed in an enabled state. To perform reverse rotation or when the RUN
command is input via the FW or RV terminals, change the setting of F02.
3) When the RUN command is input, 1, 2 and 5 light and tuning is started with operation stop-
ped. The time required for auto-tuning is approx. 5 to 40 seconds.
4)
After (3) above is completed when P04 = 2, acceleration is performed up to 50% of the rat-
ed speed and rotation tuning is started. When rotation tuning is completed, a deceleration
stop is performed. The time required for this operation is 10 seconds excluding the acceler-
ation/deceleration time.
5) When the RUN command via the FW and RV terminals is selected according to the F02 = 1
setting, tuning is completed when
is displayed. Turn the RUN command OFF. When
