?TC1 <enter> Tell Code command
1 Unrecognized command Returned response
There are many reasons for receiving an invalid command response. The most common reasons are:
unrecognized command (such as typographical entry or lower case), command given at improper time
(such as during motion), or a command out of range (such as exceeding maximum speed). A complete
list of all error codes can be found with the description of the TC command in the Command
Reference, Chapter 11.
Interrogating the Controller
Interrogation Commands
The DMC-1000 has a set of commands that directly interrogate the controller. When the command is
entered, the requested data is returned in decimal format on the next line followed by a carriage return
and line feed. The format of the returned data can be changed using the Position Format (PF),
Variable Format (VF) and Leading Zeros (LZ) command. See Chapter 7 and the Command
Reference.
