Function
Use this parameter to activate or deactivate the Reverse Compensated
Motion Detection feature for cutter compensation. A reverse motion error
is generated when any two consecutive compensated tool paths reverse
direction 180 degrees. This includes generated motion blocks.
Enabled -- When this parameter is set as enabled, the control generates an
error and halts program execution whenever a reverse motion error occurs.
Disabled -- When this parameter is set as disabled, the control ignores any
reverse motion errors and allows the program to execute.
