¡ Input circuit configuration
Shaded area indicates internal photo coupler ..ON.. .
EXT input signal
EXT photo coupler ..ON.. enables a function by external
F/H input signal.
EXT photo coupler ..OFF.. enables the set ting of a
number of micro steps by main units rotary switch S.S.
F/ H input signal
F/H photo coupler ..ON.. sets HALF step (2-division)
operation.
F/H photo coupler ..OFF.. sets FULL step (1-division)
operation.
Refer to switching EXT and F/H input signal in the
[FULL/HALF input signal, command pulse, and step
angle select].
When switching the step angle by EXT and F/H input
signal, the phase origin LCD may not turn ON and the
phase origin monitor output may not output when stop.
Refer to the MON output in the [Output Interface].
¡ Output circuit configurationiBUSYAMONAALj
Output interface
¡ Mon output
When the motor excitation phase is at the phase origin
(power ON status), the photo coupler is turned ..ON.. ,
and the upper D.P of status LED turns on synchronously.
Output from MON is set to on at every 7.2 degrees of
motor output shaft from phase origin.

When changing the division setting by F/H input signal.
When changing the motor division setting by the
external input signal and the rotary switch as shown in
the example below, the motor cannot stop where MON
output signal can be output. Take this into consideration
when using the MON output signal.
