Position control

Positioning control is implemented for the specified axis from the current position to specified position.
(1) Positioning control by ABS (absolute) method
Positioning is performed by specifying a position with reference to the OP. The moving direction is determined by
the current position.
Ex. Operation when the starting point address is 2000 and "Positioning address/movement amount" is set to
11000:
(2) Positioning control by INC (incremental) method
Positioning is performed by the set movement amount from the current position being the starting point. The
moving direction is determined by the sign of "Positioning address/movement amount."
Ex. Operation when the starting point address is 2000 and "Positioning address/movement amount" is set to -
11000:
(3) Precautions
If the value of "Positioning address/movement amount" exceeds the upper limit of the software stroke, a
"Software stroke limit+" error (Axis 1 error code: 1103) occurs. If the value is smaller than the lower limit of the
software stroke, a "Software stroke limit-" error (Axis 1 error code: 1104) occurs. In these cases, position control
does not start.
