Mode setting
Setting M1 and M2 selects one of the following modes: 2-phase, 1-2-phase, W1-2-phase, and
2W1-2-phase modes.
(3)
Monitor ( MO ) output
The product supports the use of monitor output to monitor the current waveform location.
For 2-phase mode, the MO output is Low if the timing of the A-phase current = 100% and that of
the B-phase current = -100%.
For 1-2-phase, W1-2-phase, or 2W1-2-phase mode, the MO output is Low if the timing of the
A-phase current = 100% and and that of the B-phase current = 0%.
(4)
Reset pin
The product supports the use of reset input to reset the internal counter.
Setting RESET to Low resets the internal counter, forcing the output current to the same value as
that when the MO output is Low.
(5)
Phase mode switching
To avoid step changing during motor rotation, the current must not fluctuate at phase mode switching.
Pay attention to the following points.
(a) During switching between 2-phase and other phase modes, the current fluctuates.
(b) When switching between phase modes other than 2-phase, the current can be switched without
fluctuation if the timing of MO output = Low.
However, when switching as follows, set RESET to Low beforehand:
from 1-2-phase to W1-2-phase or 2W1-2-phase mode;
from W1-2-phase to 2W1-2-phase mode.
