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 listing of all codes is listed in the TC

Interrogating the Controller
Interrogation Commands
The DMC-1700/1800 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.
