Appendix 3 Comparison of the QD73A1 and the AD70/A1SD70
Remark
Positioning execution time (BUSY signal (X14) ON to Positioning complete signal (X15) ON) of the QD73A1 and
AD70/A1SD70 may be different since their internal processing methods are different.
As a result, the timing when In-position signal (X16) turns on may also vary.
Adjust positioning execution time using the following methods if the difference of the execution time (or the timing when In-
position signal (X16) turns on) affects the system.
• Adjusting the QD73A1's positioning parameter " Acceleration time" or " Deceleration time"
• Increasing gain by changing the accumulated pulse amount setting through the QD73A1's zero/gain adjustment
