Syntax x x M S
Parameters
Description x x [ i n t ] A x i s number.
Range x x — 0 to 8.
Units x x N o n e .
Defaults x x M i s s i n g : 0 .
Out of range: E r r o r B.
Floating point: E r r o r A.
Description T h i s command reads the motor status byte of the specified axis. If the axis
number (xx) is missing or set to 0, the controller returns the motor status
bytes for all four axes, separated by a comma.
Each b i t of the status byte represents a particular axis parameter, as
described in the following table:
Bit # F u n c t i o n
Meaning for
0 1
0 A x i s in Motion N O Y E S
Motor power O N O F F
Motion direction N e g a t i v e P o s i t i v e
Right (+) travel limit
N o t tripped T r i p p e d
Left (-) travel limit N o t tripped T r i p p e d
Mechanical zero signal L o w H i g h
Not used — D e f a u l t
7 N o t used Default
The byte returned is in the form of an ASCII character. Converting the ASCII
code to binary will give us the status bits values.
NOTE
For a complete ASCII to binary conversion table see Appendix F.

- A S C I I character representing the status byte.
Errors A - U n k n o w n message code.
B — I n c o r r e c t axis number.
S — Communication time-out.

— R e a d controller status.
- R e a d controller activity.
Example 2 M S I R e a d motor status byte for axis #2.
2MSe I Controller returns character e, or ASCII character 101; converting 101
to binary we get 01100101 which has the following meaning: axis in
motion, motor power ON, motion direction positive, n o limits
tripped and mechanical zero high.
