6 SEQUENCE PROGRAM USED FOR POSITIONING CONTROL
6.4 Positioning program examples
No. 1 Parameter setting program
(For basic parameters 1 <axis 1>)
Parameter setting program for speed-position switching control (ABS mode)
<For axis 1>
(Not needed when speed-position switching control (ABS mode) is not executed)
<X4D turns ON before startup>
An example of the "Axis 1" positioning program is given in this section.
[No. 1] to [No. 3] parameter and data setting program
When setting the parameters or data with the sequence program, set them in the QD75 using the
TO command from the PLC CPU. (Carry out the settings while the PLC READY signal [Y1D] is
OFF.)
When setting the parameters or data with GX Configurator-QP, the [No. 1] to [No. 3] program
is not necessary.
