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
Supports the monitor output used to monitor the current waveform location.
For 2
phase mode,
MO
output is Low at the timing of A
phase current = 100% and B
phase
current =
－
100%.
For 1
2 phase, W1
2 phase, or 2W1
2 phase mode,
MO output is Low at the timing of A
phase
current = 100% and B
phase current = 0%.
(4)
Reset pin
Supports reset input used 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 the step changing during motor rotation, current must not fluctuate at phase mode switching.
Pay attention to the following points.
(a)
(b) When switching between phase modes other than 2
phase, current can be switched
without fluctuation at 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
When switching between 2
phase and other phase modes, current fluctuates.
