Clearing Faults
Clearing a fault will not fix the cause of the fault. The source of the fault should be investigated and
fixed before returning the system to operation. The following procedures describe various methods for
clearing faults and enabling the ULTRA Plus or IQ. When a fault is cleared using one of these proce-
dures, the following events will occur:
• The Ready relay will close.
• If assigned, the Error output will turn OFF.
• The commanded position will be set to the feedback position.
• The ULTRA Plus or IQ will be enabled and the Enabled relay will close.
• If assigned the In-Position output will turn ON.
If the condition that caused the fault to occur is still present, the ULTRA Plus or IQ will repeat the steps
that occurred when the fault was first detected.
Enable Input
Turning the Enable input OFF and ON will clear a fault and enable the ULTRA Plus or IQ.
Jog Inputs
If the fault was a travel limit (hard or soft), the jog inputs may be used to clear the fault. If the forward
limit was reached, turn ON the jog reverse input to jog off the limit. If the reverse limit was reached,
turn ON the jog forward input to jog off the limit. Once clear of the limit, turn OFF the jog input. The
ULTRA Plus or IQ will remain enabled (the fault will clear) and ready.
Cycle Power
Turn the Power OFF and then back ON. This will have the following additional effect:
• ALL volatile system Flags and variables will be initialized.
• V variables will be set to zero.
• F variables will be set to OFF.
• Position will be set to zero. If the system is in Absolute mode it will need to be homed.
• ALL outputs will be turned OFF. Outputs set to default to ON will turn ON following the execution
of the Auto program.
