DEFMCPOS
Summary Define initial position of the master
Syntax DEFMCPOS p
Parameter p = position in Master Units (MU)
Description DEFMCPOS defines the initial position of the master (in MU) in the CAM-Mode and
thus the point where the curve begins as soon as the master pulses are being
counted.
Command Group CAM
Cross Index DEFMORIGIN, SETMORIGIN, SYNCC,
Parameter: par. 33-23 Start Behavior for Sync.
Syntax Example DEFMCPOS 1000 // Set internal MU counter to 1000
Sample DEFMCPOS positions Master’s current physical position to the master curve position
indicated irrespective of what the MAPOS is.
When a DEFMCPOS 500 is issued, master’s physical position is made as the position
500 of the curve.
When a DEFMCPOS 500 is issued, master’s physical position is made as the position
500 of the curve.
†
DEFMORIGIN
Summary Set the current master position as the zero point for the master.
Syntax DEFMORIGIN
Description DEFMORIGIN defines the current master position as the zero point for the master.
The master position (MAPOS) refers to this zero point until a redefinition takes
place using DEFMORIGIN or SETMORIGIN.
NB!:
The command DEFMORIGIN can not be used with absolute encoders (see par. 32-
30 Incremental Signal Type ).
Command Group INI
Cross Index MAPOS, SETMORIGIN
Syntax Example DEFMORIGIN /* Set current position as the zero point for the master */
