Remedy
• An M code command cannot be issued in a
G27 command block and so the G27
command and M code command must be
placed in separate blocks.
• An M code command cannot be issued in a
G29 command block and so the G29
command and M code command must be
placed in separate blocks.
• Review the program.
• Check the specification.
• Check the power and cable of the connected
devices.
• Check the I/O device parameters.
• In memory mode, the programs stored in
memory may have been destroyed. Output
all of the programs and tool data once and
format them.
• Ensure that the external device (including a
floppy disk drive and IC card) that contains
the file is mounted.
• L01 DNC ERROR is displayed
simultaneously, so remedy the problem
according to the error No.
• Check the specification.
• Check the program.
