5.1 List of Status
In Table 5.1, status listed with 2 data position numbers are 2-word data. The smaller
number data position number contains the low-order word, and the larger data position
number contains the high-order word.
The data position number consists of three digits; the leading ‘
*’
is the value of (axis
number-1). Replace ‘*’ with values 0 to 7 for axes 1 to 8 respectively.
Each data position number corresponds to a word. Always use the word-based READ
instruction to access from a sequence program; using a long-word-based instruction
may cause unexpected results.
Always use word instructions when accessing from a BASIC program.

Fixed-decimal point data
Speed-related data with unit [(1/65536) pulses/ms] is fixed-point data with 1 word (16
bits) for the integer part and 1 word (16 bits) for the fractional part. The smaller data
position number contains the low-order word, and the larger data position number
contains the high-order word. For more information on fixed-point data, see the
description of fixed point data in Section 4.1, “Parameters.”

Speed data conversion program
To convert data in [(1/65536) pulses/ms] units into data in [pulses/sec] units, multiply the
data by 1000 using a long word operation, ignore the lowest-order word and the highest-
order word and use the second and the third words as long word data.
Let D0001 be long word data in [(1/65536) pulses/ms] units. The operation is as follows.
