Output frequency range from 0.01Hz to 400Hz
•
Start frequency adjustment – When the inverter starts to run, the output frequency does not ramp from 0Hz.
Instead, it steps directly to the “Start frequency” (b082), and the ramp proceeds upward from there. When you
set the “Start frequency” to 0.01Hz, the output frequency starts from 0.01Hz.
The Following are the related parameters for this function.

Caution

If you set the “Set frequency” (F001) to extremely low value, the motor may stall or be unstable rotating.
Especially in the simple positioning mode, if you set the “Creep speed” (P015) to low value, the simple
positioning may not work properly because of motor stalled.
Support of multiple pole 3 Phase Induction motors

Caution
〉
In the case of "Motor capacity" (H003/H203) and "motor poles setting" (H004/AH204) are configured to
correspond with the motor, the values of "motor constant data" (H020/H220 to H024/H224) are
automatically overridden by Hitachi standard motor's value.
With Hitachi inverter, if 8 poles or more poles are set up, 8 poles, which is Hitachi Standard mortar value,
are automatically applied. If necessary, manually configure motor constants.
Please note working of motors with 8 poles or more are not guaranteed. Some mortar may work unstable
in such cases.
