[Function] Check if valid data is contained in the axis pattern specified in operand 1 at the position
number specified in operand 2.
The output will turn ON when all of the data specified by the axis pattern is invalid (XX.XXX).
“0” is treated as valid data.
[Example 1] PTST 11 10 300 Turn ON output 300 if there are no valid values of axes
1 and 2 at position 10.
Output 300 will turn OFF if the position data is given as
follows:
[Example 2] The axis pattern can be specified indirectly using a variable.
When the command in [Example 1] is rephrased based on indirect specification using a
variable:
11 (binary)
o 3 (decimal)
LET 1 3 Assign 3 to variable 1.
PTST *1 10 300
[Example 3] LET 1 11 Assign 11 to variable 1.
PTST 11 *1 600 Turn ON flag 600 if there are no valid values in the data
of axes 1 and 2 at the content of variable 1 (position
11).
Flag 600 will turn ON if the position data is given as
follows:
No. Axis 1 Axis 2 Axis 3 Speed Acceleration Deceleration
10 100.000 50.000 XXXX.XXX XXX XXXX XXXX
11 XXXX.XXX XXXX.XXX 200.000 XXX XXXX XXXX
