What are System Programs?
System programs are a group of ULTRA Plus or IQ programs which operate differently than normal
motion programs. Some system programs automatically run upon power up. Some system programs are
used with the function keys on the Operator Terminal. Other system programs have specific functions
such as homing an axis, handling errors and warnings, or performing the Emergency Return function.
Some system programs execute at the same time as (in parallel with) motion programs.
System programs are stored in a separate directory in the Personality Module called the system direc-
tory. System programs may be edited just like a motion program and saved to program locations in the
system directory. Default system programs are included in standard Personality Modules and may be
modified as needed by the application.
The system programs are:
• System Program 0-AUTO (Automatically runs on power up)
• System Programs 1-24-Operator Terminal function key Programs
• System Program 25-HOME
• System Program 26-Emergency Return
• System Program 27-Error Routine
• System Programs 28-31-Reserved for future development
