“H” .. Counterclockwise direction (as seen from the output shaft)
Excitation drive is forcibly turned ON/OFF.
“H” .. Normal operation (Excited)
“L” ... Excitation drive is forcibly shut off (Not excited)
Motor wire current value is set in the range of 0 to 2.0 (A)/phase by
applying the analog voltage 0 to 5 (V).
Set the excitation mode.
