When Define Home Turns ON
For this input to function the ULTRA Plus or IQ must NOT be running a program (Define Home is
ignored while a program is running). When Define Home turns ON the DHCMD flag is turned ON.
This internal flag causes the present position to be defined as home (position zero). Refer to Appendix
A, System Programs, for more detailed information.
When Define Home Turns OFF
This edge is ignored by the ULTRA Plus or IQ.
Hardware Reset
The Hardware Reset input can be assigned to any general purpose input that is not already assigned to a
dedicated function.
When Hardware Reset is ON
•
The ULTRA Plus or IQ stops executing any program,
•
turns OFF the Ready output,
•
disables the ULTRA Plus or IQ immediately (without decelerating the motor to a stop if moving),
•
resets any faults,
•
performs power-up diagnostic tests,
•
turns ON the Ready output,
•
enables, if there are no faults, and if the Enable input is on,
•
turns ON the Enable Output, if the Enable input is on,
•
and then starts the Auto Program (System Program zero).
This cycle is repeated as long as the Hardware Reset is ON
When Hardware Reset is Turned OFF
This edge is ignored by the ULTRA Plus or IQ.
X Kill Motion
The X Kill Motion input can be assigned to any general purpose input that is not already assigned to a
dedicated function. The X Kill Motion is used to stop program motion and stop a program from execut-
ing. When turned ON, this input sets the system Stop flag ON. When turned OFF this input resets the
system Stop flag. This input has the same effect as the STOP instruction. Refer to Part 5
•
Reference, STOP for more detailed information.
Note: The X input does not stop Jog INPUT motion. Jog motion will slew to a stop and then begin
again.
