Preparing the mechanical system
As preparation for performing rotation tuning, remove machine couplings, and disable safety in-
terlocks.

Execution of auto-tuning
1) Set one of 1, 2 or 5 to parameter P04, and press the
Parameter No.
2) Input the RUN command. In the factory default state, forward rotation is performed when
the
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
