WORDS
POS2 Position, Encoder 2 Position
Purpose Encoder 2 position in user units, scaled by the Scale2 parameter.
Syntax variable = POS2
variable The variable may be a nonvolatile variable Gn, a volatile vari-
able Vn, or a system variable.
Remarks
See Also POS1, POSN
Example V1 = POS2
POS3 Position, Encoder 3 (Optional) Position
Purpose Encoder 3 position (from option card).
Syntax variable = POS3
variable The variable may be a nonvolatile variable Gn, a volatile vari-
able Vn, or a system variable
Remarks
See Also POS1, POS2, POSN
Example V1 = POS3
POSN Position Feedback Position
Purpose Feedback position in user units, scaled by the Scale parameter.
Syntax variable = POSN
variable The variable may be a nonvolatile variable Gn, a volatile vari-
able Vn, or a system variable.
Remarks POSN is the position of the encoder that is currently being used as the feedback
encoder (typically encoder 1). The CONFIG menu establishes which encoder is cur-
rently the feedback encoder. The position of that encoder is read using the correspond-
ing SCALE to determine POSN.
