Fault Conditions
Normally any fault will cause the ULTRA Plus or IQ to DISABLE, stopping motion and program exe-
cution. Refer to Part 5
•
Language Reference, DISABLE for more detailed information.
On some machines you may want the ULTRA Plus or IQ to continue running even after some faults
occur. This is accomplished by setting Disable on Fault to Partial. In this case, the following faults are
disabled: Iavg fault, Motor Overtemperature, Soft Forward Limit, and Soft Reverse Limit. All faults
will cause the Error output to turn ON (if enabled). However, if Disable on Fault is set to Partial, and a
fault listed above occurs, the ULTRA Plus or IQ will remain enabled and execute motion programs nor-
mally. The Error output in this case serves as an alarm, and a programmable logic controller (PLC) or
other controller can then gracefully shut down the machine without damaging the tooling or work piece.
This setting is made in the Parameter menu, System dialog box of IQ Master, or with the FLTDIS Host
Language Command. Refer to Part 2
