Pn638
Pn63A
Pn63C
6.3.1

When the Coordinates are the Linear Type

For a ball screw or other equipment with linear coordinates, set Pn637 to n.0 (Moving
Mode), set the forward software limit (P-LS) in Pn638, and set the reverse software limit (N-LS)
in Pn63A.
One of the following errors will occur if the positioning target point exceeds a software limit:
Moving Disabled Error due to P-LS (E4DE) or Moving Disabled Error due to N-LS (E4EE).
One of the following errors will also occur if ±INFINITE is specified for the target position (POS)
in the program table: Moving Disabled Error due to P-LS (E4DE) or Moving Disabled Error due
to N-LS (E4EE).
If the motor reaches a software limit during jog speed table operation, the motor will be
stopped at the deceleration rate set in Pn640.
If you set both Pn638 and Pn63A to 0, the software limits are disabled.
The software limits are enabled when homing is completed.
