The software limit function is used to set upper and lower limits for the range of machine movement
in fixed parameters so the MP2300 can constantly monitor the operating range of the machine. The
function can be used to help prevent machine runaway or damage due to incorrect operation as well
as incorrect references in a motion program.
Disable the software limits in the SERVOPACK to use the MP2300 for position control in the
machine coordinate system.
Refer to your SERVOPACK manual for the procedure on disabling software limits.
