Select a Possible Solution (SEQ +/–)
The position you define for the machining plane is used by the TNC to
calculate the appropriate positioning of the rotary axes present on the
machine. In general there are always two solution possibilities.
Use the SEQ switch to specify which possibility the TNC should use:
8 SEQ+ positions the master axis so that it assumes a positive angle. The
master axis is the 2nd rotary axis from the table, or the 1st axis from
the tool (depending on the machine configuration (see figure at top
right)).
8 SEQ– positions the master axis so that it assumes a negative angle.
If the solution you chose with SEQ is not within the machine’s range of
traverse, the TNC displays the Entered angle not permitted error
message.
