DEL (Delay the Command Interpreter)
Description:
Delays <uint> milliseconds.
Format:
DEL <uint>
Arguments:
<uint> is the delay value in milliseconds.
Response:
None
Notes:
DEL can only be used in macros. Do not mistake MAC DEL
(deletes macros) for DEL (delays).

MAC command (p. 171) and in the "Controller Macros" (p.

DFH (Define Home Position)
Description:
Redefines the zero position of the specified axis by setting
the position value to zero at the current position.
If no arguments are specified, DFH defines the zero
position of all axes.
Format:
DFH [{<AxisID>}]
Arguments:
<AxisID> is one axis of the controller.
Response:
none
Troubleshooting: Illegal axis identifier
Notes:
DFH sets the current position of the axis to zero and saves
the position value which was valid when the command
was called as offset in the volatile memory. By adding this
offset to the response, the output values of the following
commands are adapted to the new zero position:
▪
POS? (p. 182) (Get the current position)
▪
TMN? (p. 198) (Get the minimum commandable
position)
▪
TMX? (p. 199) (Get the maximum commandable
position)
DFH does

definition of travel range and soft limits (p. 25).
The offset is reset to zero in the following cases:
