12 CONTROL SUB FUNCTIONS

12.7.7 Pre-reading start function

The "pre-reading start function" does not output pulses while the execution prohibition
flag is ON if a positioning start request is given with the execution prohibition flag ON,
and starts outputting pulses within 1.3ms (QD75P N/QD75D N) or 3ms
(QD75P /QD75D ) after OFF of the execution prohibition flag is detected. The
positioning start request is given when the axis is in a standby status, and the
execution prohibition flag is turned OFF at the axis operating timing. This shortens the
virtual start time. The QD75 normally takes 1.5 to 2.0ms (QD75P N/QD75D N) or 6
to 7ms (QD75P /QD75D ) from when it receives a positioning start request until it
starts pulse output (start time). Some systems often need the start time to be
shortened. This "pre-reading start function" can improve the tact time of the system.

The "pre-reading start function" will be explained below.

[1] Control details

The pre-reading start function is performed by turning ON the positioning start
signal [Y10, Y11, Y12, Y13] with the execution prohibition flag [Y14, Y15, Y16,
Y17] ON, or by executing the dedicated instruction (ZP.PSTRT1, ZP.PSTRT2,
ZP.PSTRT3, ZP.PSTRT4). However, if positioning is started with the execution
prohibition flag ON, the positioning data is analyzed but pulse output is not
provided. While the execution prohibition flag is ON, "

status" remains unchanged from "5: Analyzing". Pulse output starts within 1.3ms
(QD75P N/QD75D N) or 3ms (QD75P /QD75D ) after the execution
prohibition flag [Y14, Y15, Y16, Y17] has turned OFF, and "

that matches the control system. (Refer to Fig. 12.49)
