5DATA USED FOR POSITIONING CONTROL

Da.1 Operation pattern

MELSEC-Q

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)

Continuous positioning with one start signal .......... Continuous positioning control

Positioning continued

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 "

1 : Use the value set in "

2 : Use the value set in "

3 : Use the value set in "

Pr.9 Acceleration time 0".

Pr.25 Acceleration time 1".

Pr.26 Acceleration time 2".

Pr.27 Acceleration time 3".
