• When crest value of input signal exceeds 5V, add external limiting resistor R<br />
so that input current becomes approximately 10mA.<br />

Example: 5-phase, full-division (Full Step)<br />
• Photo coupler at phase origin of motor excitation (status at power on) is set<br />
toON<br />
• Inputting pulse turns on photocoupler every 7.2of motor output axis from<br />
phase origin.<br />
• Set command frequency to 50kpulse/s or less to use phase origin monitor.<br />
• Perform switching of division number via step-angle selection input<br />
signal (SSEL) with phase origin monitor output turned on and motor being<br />
stopped.<br />
• Switching division number at the point other than excitation origin may<br />
cause that phase origin monitor output is not correctly output.<br />
