・The motor capacity and the number of poles will be set by
Hitachi characteristics table.
・For SM/PMM, frequency, voltage, and the motor constants
setting are necessary.
・If the maximum current of the motor is decided, Set the
Overcurrent detection level [bb160] with a margin.

(0.01 to 500.00(kW)
for SH1-1600H or above models)
0 to 23 (2 poles to 48 Poles)
※Initial value depends on the inverter.
・If motor capacity [Hd102], number of poles [Hd103] are
changed, the motor characteristics are set according to the
internal Hitachi table values.
・The values of [Hd110] to [Hd114] can be acquired by no
rotation auto-tuning.

Sync.M, 1st-motor
・The synchronous control is switched to sensorless vector
control when the frequency reference is the base
frequency[Hd104] × [Hd130].
・By [Hd131], the sensorless vector control no-load current is
set.

・For SM/PMM, if initial motor position estimate is enabled by
[Hd132], the inverter drives after magnetic pole position
estimation. If a slight reverse rotation occurs at startup after
the magnetic pole position estimation operation, set the start
position offset in the operation direction to [Hd137].
