9 POSITIONING CONTROL
[2] 1-axis linear control (INC)
Operation chart
In incremental system 1-axis linear control, addresses established by a machine
OPR control are used. Position control is carried out from the current stop position
(start point address) to a position at the end of the movement amount set in " Da. 6
Positioning address/movement amount". The movement direction is determined by
the sign of the movement amount.
Reverese direction

Example
When the start point address is 5000, and the movement amount is -7000, position control is carried
out to the -2000 position.
