DisablingError Detection
You can disable all of the above error detection (with the exception of
circular departure too small cases) for a specific block or portion of a part
program . To disable the error detection for a specific block, your system
installer must have defined an M-code in AMP. By programming this
M-code in a block, you can disable all error detection for dresser/wheel
radius compensation. Error detection is disabled until another M-code
defined in AMP to re-enable error detection is programmed in a block.
Important: You cannot disable circular departure too small cases. It is not
possible for the control to execute a compensated path when this error
occurs.
The default condition is error detection enabled. Default values for these
M-codes are:
M800 - disables error detection
M801 - enables error detection
See documentation prepared by your system installer for the M-codes used
on a specific system.
