Thread recutting impossible

Details
The lead axis for thread recutting is not present in a thread recut enabled part system.
A variable lead thread cut command has been given in the first thread cut block of thread recutting.
Remedy
Thread recutting is not supported. Disable thread recutting or press RESET to cancel the alarm, and cor-
rect the program.
M01

Thread recutting data illegal

Details
The lead axis and spindle for thread cutting are different from those predetermined.
Remedy
Disable thread recutting or press RESET to cancel the alarm, and correct the settings of lead axis and spin-
dle.
M01

Variable speed thread disabled

Details
 "#8045 Varying spd thread" has been set to "1" to issue a variable speed thread cut command even
though the function is not included in the specifications.
A variable speed thread cut command has been given while the feed axis acceleration/deceleration type
is soft acceleration/deceleration.
A variable speed thread cut command has been given while the spindle encoder signal is not sent via serial
input.
A variable speed thread cut command has been given even though the spindle, lead axis or plane com-
posing axes are controlled by drive other than MDS-E Series.
The spindle intended for thread cutting is executing synchronous tapping, spindle synchronization, guide
bushing spindle synchronization or spindle/C axis control.
Remedy
Check the specifications.
Check the parameters.
Check the program.
Check the Encoder selection signal (R register).
M01

Synchronization mismatch

Details
Different M codes were each commanded as synchronization M code in each of the two part systems.
Synchronization with the "!" code was commanded in another part system during M code synchronization.
Synchronization with the M code was commanded in another part system during synchronization with the "!"
code.
Remedy
Correct the program so that the M codes match.
Correct the program so that the same synchronization codes are commanded.
M01 Multiple C axes select invalid
Details
The "C axis selection" signal has been changed when the multiple C axes selection is not available.
The selected axis by the "C axis selection" signal cannot be controlled for the multiple C axes selection.
Remedy
Correct the parameter settings and program.
M01 Tap retract Sp select illegal
Details
Tap retract has been executed with a different spindle selected. Cutting feed is in wait state until synchroniza-
tion is completed.
Remedy
Select the spindle for which tap cycle was halted before turning ON the "tap retract" signal.
