Example Commands
Table Format
The following tables divide variables and flags into functional groups.
The Flag/Variable column contains an “F” if the command sets or reads a flag, a “V” if it contains a
variable with a standard size, or the size of the variable if it is something other than the standard size.
Refer to Part 4
•
Programming, User Variables, and Arithmetic for more detailed information on the
standard size of variables.
The Read/Write column identifies which variables can be read (R) and which can be written (W) or set.
The Personality Module (PM) column identifies variables stored in the Personality Module, making
them nonvolatile. A “#” identifies variables stored in the Personality Module that have a runtime value
as well. Values marked with a “#’ are returned to the value in the Personality Module at program com-
pletion.
Serial Command Resulting Action
ACC = 200 Set the Personality Module default acceleration to 200 user units per Time-
base.
#ACC = 300 Set the current runtime value of acceleration to 300 user units per Time-
base.
ACC Read the value for acceleration stored in the Personality Module in user
units per Timebase.
#ACCEL Read the current runtime value for acceleration in user units per Timebase.
Note: The runtime value of most variables is stored in internal units. When the runtime value is
accessed the conversion to and from internal units is transparent. Small rounding errors may occur
during conversion of runtime parameters, so that the value returned may not exactly match the
value set.
