POSITIONING CONTROL
[2] 1-axis linear control (INC)
Operation chart
In 1-axis linear control of incremental system, addresses established by a machine OPR
control are used. Position control is performed from the current stop position (starting
address) for the movement amount set in "
The movement direction is determined by the sign of the movement amount.
Reverse direction
Movement direction for
a negative movement amount
Example
When the starting address is 5000 and the movement amount is -7000, position control is
performed to the -2000 position.
