CHAPTER 6 VARIOUS SETTINGS

6.2 Switch Setting
6.2.2 Accumulated pulse setting
(b) Accumulated pulse amount and analog output voltage from the QD73A1
The analog output voltage from the QD73A1 is controlled in proportion to accumulated pulse amount.
The following is an example of selecting an option in "Accumulated pulse setting".
Ex.
Maximum speed: 4Mpulse/s, position loop gain: 30s
-1
If the number of accumulated pulses is 133333, "-148000 to 148000 pulse" should be selected in
"Accumulated pulse setting" so that analog output voltage will not be saturated.
