・After setting the motor basic parameters, by the
auto-tuning operation the constant of the motor will be
able to acquired.
・For no-rotation auto-tuning, the following variables are
acquired, IM:[Hb110] to [Hb114], SM(PMM):[Hd110] to
[Hd114].
・For rotation auto-tuning, the following variables are
acquired, IM:[Hb110] to [Hb118]. Keep the operation
conditions, as the motor can rotate.
・Auto-tuning start is done by the RUN-key ([HA-02] Initial

・If hunting occurs while a pump or a fan is being operated,
lower the stabilization constant for adjustment.
・In the case the load is relatively light and hunting occurs,
then increase the stabilization constant.
・[HA112] and [HA113] adjust the output frequency
characteristics of [HA110] stabilization constant. Be sure
to set the start ratio to a value smaller than the end
ratio. When “Start ratio> End ratio”, the end ratio
setting is ignored and the same value as the start ratio
is set.

*ASR: Automatic Speed Regulator
・Speed response gain of the motor control can be changed.
・The PI gain used for control is as follows according to the state
of the input terminal 063[CAS] and 064[PPI] terminals.
■In the case of input terminal [CAS]
