Output Current Waveform of Pseudo Sine Wave
9 micro-step from 0 to 90° drive is possible by combining Current DATA (AB & CD) and phase data.
For input Current DATA at that time, see section on Current X in the list of the Functions.
Depending on the load, the optimum condition changes for selecting MIXED DECAY MODE when the sine wave
rises and falls. Select the appropriate MIXED DECAY TIMING according to the load.
