Axis Omission; Block Preread - YASKAWA MOTIONPACK-110 Descriptive Information

3.5.5. AXIS OMISSION
Program check, etc., can be made by releasing a specific axis from motion control and
performing idle operation.
If start signal (STR) is turned on when axis omission signal (NEG) is on in the
memory operation mode (MEM), only the specified axis is not controlled and the machine
does not move. The current value display does not change either.
3.5.6 OPTIONAL BLOCK SKIP FUNCTION
When an optional block skip signal (SK1-SK8) is turned on or off, the blocks which contain
"/n" (n = 1 to 8) are selectively omitted in the execution of the program.
For example, when an SK2 signal is ON, all the commands in the block containing
"/2" are omitted until the block ends.
This function is ineffective on the block under execution or blocks stored in the
advance reading buffer. During memory operation, it becomes effective from the block to be
read after the signal.
3.5.7 MANUAL INTERRUPTION OF AUTOMATIC OPERATION
When a manual operation (JOG mode, STEP mode, RAPID mode, or HANDLE mode)
intervenes during a memory or a DNC operation, the distance covered by the manual
operation has the effect of shifting the motion path. Therefore, when the memory opeation
mode is restored after the manual interruption and the automatic operation process is
restarted by a start signal, the machine follows the shifted path. A machine coordinate
system does not depend upon absolute programming (G90) and incremental programming
(G91).

3.5.8 BLOCK PREREAD
In normal operation, one-block data is preread and data processing is
performed to prepare for the next operation. The maximum capacity of one-block data is 128
characters (containing EOB).
