WORDS
HLIMITS
Travel Limits Enabled Flag
System
Purpose
Set if travel limit inputs are enabled.
Syntax
variable = HLIMITS
variable
The variable may be a nonvolatile flag Bn, a volatile flag Fn, or
another system flag.

Example
F4 = HLIMITS
IF HLIMITS = ON

HOFFS
Home Offset
Home
Purpose
Set the Home Offset. Home Offset specifies the distance from the encoder index, or
home switch if there is no index, to the home position. The sign specifies the direction
of the offset.
Syntax
HOFFS = value
variable = HOFFS
value
The Home Offset is entered in user units. User units are defined
by the SCALE parameter. Value can be a constant, a nonvolatile
variable Gn, a volatile variable Vn, or a system variable.
variable
The variable can be a nonvolatile variable Gn, a volatile vari-
able Vn, or a system variable.
Remarks
The default home program finds the home position based on the home switch and/or
the encoder index. Once this position is found, an incremental move is made with a
distance of HOFFS. Home position (zero) is then defined. A detailed description of the
home program is in Appendix A.
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, Velocity/Accel dialog box.
