12.7.8 Pre-reading start function

The "pre-reading start function" does not outp ut pulses while the execution prohibition

flag is ON if a positioning start request is given with the execution prohibition flag O N,

and starts outputting pulses within 3m after O FF of the execution prohibition flag is

detected. The positioning start request is gi ven 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 norm ally takes 6 to 7ms from when it

receives a positioning start request until it star ts pulse output (start time). Some

systems often need the start time to be shortene d. This "pre-reading start function" can

improve the tact time of the system.

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

[1] Controls

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 (PSTRT1, PSTRT 2, PSTRT3,

PSTRT4). However, if positioning is start ed with the execution prohibition flag

ON, the positioning data is analyzed but pulse output is not p rovide d . While the

execution prohibition flag is ON, " Md.26 Axis operation status" remains

unchanged from "5: Analyzing". Pulse out put starts within 3ms after the execution

prohibition flag [Y14, Y15, Y16, Y17] has tur ned OFF, and " Md.26 Axis

operation status" changes to the status (e.g. d uring position control, during speed

control) that matches the control system. (Ref er to Fig. 12.48)
