• Two-phase trapezoidal positioning control (
There are two systems to specify a positioning address: the absolute system in which a positioning end address is
specified and the incremental system in which movement amount from a start address to an end address is specified.
Specify the absolute system or the incremental system using one of the following start signals.
Start signal
Absolute positioning start signal (Y21)
Forward start signal (Y22)
Reverse start signal (Y23)
(1) Positioning control
Set a positioning address and positioning speed for this type of control. Absolute system positioning or
