DISLIM
Travel Limits Disable System
Purpose Disables the hardware travel limits when set to ON. Enables the inputs when OFF.
Syntax DISLIM = value
variable = DISLIM
value The value can be ON, OFF, a nonvolatile flag Bn, a volatile flag
Fn, or another system flag.
variable The variable may be a nonvolatile flag Bn, a volatile flag Fn, or
another system flag.
Remarks Regardless of the state of this flag, the limit switches, inputs 1 and 2, may be read. For
example:
F1 = I1 ;read forward limit switch
F2 = I2 ;read reverse limit switch
The travel limit switches must be enabled (HLIMITS = ON) for DISLIM to have any
effect.
Changes made to this flag by a program are only in effect while the program is run-
ning. When the program ends it will return to the setting stored in the Personality
Module.

DISLIM = ON ;Disable the hardware travel limits

ues with the statement after the WHILE.
