(c) Operation of the Program
• If there is the rising edge of M0001 used as the direct starting instruction signal of axis X, the DST
instruction is executed.
(Not if axis X is operating or in error.)
• If the origin is not fixed when the DST is started, error code 224 will appear and operation will not
occur. In such a case, turn on M0000, execute the ORG instruction and thereby carry out the
origin return, and start the DST instruction.
1) If the DST instruction is executed, the positioning operation gets started as set in the operand
as follows.
- Since sl and ax are 0, built-in positioning axis X is started.
- The target position will be 100,000 pulse set as double word in D0002.
- The target speed will be 30,000 pps set as double word in D0002.
- After positioning is finished, the dwell time becomes 100ms set in D0004, and No.123
designated in D0005 will be output as the M code.
- Since the control word of D0006 is H`20, the acceleration/deceleration pattern will follow the
acceleration time 2 and deceleration time 2 of the basic parameter, and the positioning
operation will be done as the absolute coordinates. If the DST instruction is started, the
position control will be executed in the absolute coordinates, it will operate up to the
100,000 pulse at 30,000 pps, then stop, and after the dwell time of 100 ms passes, the
positioning is finished, and M code outputs 123.
2) If positioning is finished by direct starting, positioning finish signal (axis X:K4202) turns on for a
scan.
