(b) Positioning data setting
The following table lists the positioning data to be set, setting condition, and check timing.
Setting item
Positioning pattern

Positioning speed
Da.3
V1
(2) Two-phase trapezoidal positioning control
Set positioning addresses (P1 and P2) and positioning speed (V1 and V2) for this type of control. Positioning of
the absolute system or the incremental system is executed first to the positioning address P1 at the positioning
speed V1, then to the positioning address P2 at the positioning speed V2 by one positioning start command.
(a) Operation of two-phase trapezoidal positioning control
The operation is as follows.

Note that the set data at the
rise (ON) of a positioning
start signal (Y21 to Y23) are
used for the operation. If the
0pulse data are written when BUSY
signal (X14) is on, the data
will be accepted at the rise
(ON) of the next positioning
0pulse/s
start signal (Y21 to Y23).
