5 DATA USED FOR POSITIONING CONTROL

Da.1 Operation pattern

The operation pattern designates whether positioning of a certain data No. is to be
ended with just that data, or whether the positioning for the next data No. is to be
carried out in succession.

[Operation pattern]

Positioning complete

Independent positioning control
(Positioning complete)

Positioning
continued

Continuous positioning with one start signal

Continuous positioning control

Continuous path positioning with speed change

Continuous path control

.............................................................................

.....

..........

1) Positioning complete..................... Set to execute positioning to the designated

address, and then complete positioning.

2) Continuous positioning control ..... Positioning is carried out successively in

order of data Nos. with one start signal.
The operation halts at each position
indicated by a positioning data.

3) Continuous path control................ Positioning is carried out successively in

order of data Nos. with one start signal.
The operation does not stop at each
positioning data.

Da.2 Control system

Set the "control system" for carrying out positioning control.

Note)

When "JUMP instruction" is set for the control system, the " Da.9

Dwell time" and "

Da.10

M code" setting details will differ.

In case you selected "LOOP" as the control system, the "

Da.10

M code" should be set differently from other cases.

Refer to Chapter 9 "Major positioning control" for details on the control
systems.

If "degree" is set for " Pr.1 Unit setting", circular interpolation control

cannot be carried out. (The "Circular interpolation not possible error"
will occur when executed (error code: 535).)

Da.3 Acceleration time No.

Set which of "acceleration time 0 to 3" to use for the acceleration time during
positioning.

0 : Use the value set in " Pr.9 Acceleration time 0".

1 : Use the value set in "

Pr.25

Acceleration time 1".

2 : Use the value set in "

Pr.26

Acceleration time 2".

3 : Use the value set in "

Pr.27

Acceleration time 3".
