11.2.5 MOB output selection setting (only when micro step driving)
The output function of MOB can be selected by D7. It becomes effective only when the micro step driving mode
selected.
D7 = 0: MOB is output once per cycle.
D7 = 1: MOB is output four times per cycle.
For the output position of MOB, refer to
11.2.6 MOB output position setting
(set by D8).
D7
MOB Output
0
1 pulse/cycle
1
4 pulses/cycle
11.2.6 MOB output position setting (when micro step driving or 1-2 phase excitation driving)
The MOB output timing position can be selected by D8. It becomes effective when the micro step driving mode or
the 1-2 phase excitation driving mode selected.
D8 = 0: MOB is output at the one-phase excitation position (where the current of ch1 or ch2 is 100%) .
D8 = 1: MOB is output at the two-phase excitation position (where the currents of ch1 and ch2 are the same) .
Selection of MOB output (D7) is made in accordance with the setting of D8.
When D8 = 1, no signal is output from the MOB pin immediately after reset. In addition, MOB
1
and MOB
2
cannot be
set individually.
