1-Axis Linear Control - Mitsubishi Electric A1SD75P1-S3 User Manual

9 MAIN POSITIONING CONTROL

9.2.2 1-axis linear control

In "1-axis linear control" (" Da.2 Control method" = ABS linear 1, INC linear 1), one
motor is used to carry out position control in a set axis direction.

Operation chart
In absolute system 1-axis linear control, addresses established by a machine zero
point return are used. Positioning is carried out from the current stop position (start
point address) to the address (end point address) set in " Da.5 Positioning
address/movement amount".
Example
When the start point address (current stop position) is 1000, and the end point address (positioning address) is 8000,
positioning is carried out in the positive direction for a movement amount of 7000 (8000-1000)

Positioning data setting example
The following table shows setting examples when "1-axis linear control (ABS linear
1)" is set in positioning data No. 1 of axis 1.
Setting example
Positioning Set "Positioning complete" assuming the next positioning data will not
complete be executed.
ABS linear 1 Set absolute system 1-axis linear control.
Designate the value set in " Pr.26 Acceleration time 1" as the
1
acceleration time at start.
Designate the value set in " Pr.9 Deceleration time 0" as the
0
deceleration time at deceleration.
Set the positioning address. (Assuming "mm" is set in " Pr.1 Unit
8 0 0 0 . 0 µ m
setting".)
– Setting not required (setting value will be ignored).
6000.00mm/min Set the speed during movement to the positioning address.
Set the time the machine dwells after the positioning stop (pulse output
500ms
stop) to the output of the positioning complete signal.
Set this when other auxiliary operation commands are issued in
10
combination with the No. 1 positioning data.
