(h) Absolute pulse coder (APC) alarms
First check ID No. 70. If bit 0 is on, check the following:
ID No. 71 to 78
ID No. 81 to 88
ID No. 90 to 98
Each of ID No. 71 to 78 corresponds to an axis; bit 5, if on,
indicates that alarm No. 300 has occurred.
Each of ID No. 81 to 88 corresponds to an axis; the information
of each ID No. indicates an APC alarm number.
Check ID No. 90 to determine whether to read the information of
ID No. 91 to 98 indicating serial pulse coder (SPC) alarm
information. Correct information can be read if bit 2 is on. Each
of ID No. 91 to 98 corresponds to an axis.
All information consists of one–byte data. For one–byte data, see
Section 6.29.3.(1)(b). For the meaning of each bit, see the APC
alarms table.
