UNSIGNED LONG:
UNSIGNED INT:

Upon receiving a command, the controller answers by sending the function parameter and variable list. General purpose commands are not prefixed. These commands only consist of the command identifier and therefore need the general structure

“Command Identifier” [“Delimiter”]“Parameter list” [CR]

With the non–prefixed commands, no delimiter is mandatory, but the blank space can be inserted optional.

Parameters and Units

The parameters used within the ASCII commands are integers of different sizes:

INTEGER: 16 bit value ranged 8000.. 7FFF hex ( –215.. +215–1 dec. ) 16 bit value ranged 0.. FFFF hex (0..216–1 dec.)

LONG: 32 bit value ranged 80000000.. 7FFFFFFF hex ( –231.. +231–1 dec.) 32 bit value ranged 0.. FFFFFFFF hex ( 0.. +232–1 dec.)

STRINGS: Strings of ASCII characters (0 .. FF hex).

A string parameter is preceded and terminated with double quote character ()!

Commands, which accept or require more than one parameter, use parameter lists which are composed of the sequence of parameters necessary, with the delimiters blank space or comma between.

The number of the parameter can be given as decimal value or as hexadecimal value. Hexadecimal values are preceded by one or more 0–character (30 hex), while decimal values are taken as default without indicator.

The ASCII command set description below, also shows the units of the parameters respectively indicate parameters with no units. For best resolution within the accepted range, the units of the parameters are not chosen according to SI, but most of the units used are SI units multiplied with potentials of 10.

In some cases, units are related to system properties and can therefore not be same for all applications. The following is an example of how to calculate Counts and Limits, used with positioning and homing:
