692 Using the RIO Adapter Option
While a jog is in progress, both the axis locked and axis fault dedicated
discrete RIO outputs from the motion controller for the selected axes are
cleared, provided there are no faults active on the axis. When the jog has
finished successfully and the position error of the axis is less than the
position lock tolerance, the axis locked dedicated discrete RIO outputs
from the motion controller for the selected axes are set. If a fault occurs
during the jog, the axis fault outputs for the selected axes are set, and the
axis locked outputs are cleared. See Dedicated Discrete Outputs later in
this section for more information on the axis locked and axis fault bits.
The recommended ladder logic for jogging each of two axes from
individual positive and negative jog inputs to the PLC is shown in the
following exhibit. The rack address in the motion controller is set to 5 and
the starting group parameter to 0. Thus the dedicated discrete RIO bits
appear in I/O group 1 of rack 5 (
I/O:051 ).
