units. User units are defined by the SCALE parameter. The dis-
tance can be a constant, a nonvolatile variable Gn, a volatile
variable Vn, or a system variable.

variable

The variable may be a nonvolatile variable Gn, a volatile vari-
able Vn, or a system variable.

Remarks

The WINDOW setting in conjunction with the In-Position mode determine the opera-
tion of the INPOSN flag and the In-Position output (Output 07 if assigned). If the
In-Position mode is set to relative, when the Following Error (FE) is less than WIN-
DOW, the INPOSN flag is set ON and the INPOSN output is turned ON if assigned. If
the In-Position mode is set to Absolute, motion will also have to be stopped for the
flag and the output to be set. The In-Position mode is set in the Parameter menu, Out-
puts dialog box.

Changes made to this variable by a program are only in effect while the program is
running. When the program ends it will return to the value stored in the Personality
Module. If no change is made to this variable by the program, the value in the Person-
ality Module is used. The value in the Personality Module is set in the Parameter
menu, Gains/Limits dialog box.
