(e) Stop during interpolation operation
During interpolation, both axes are stopped by either the
X- or the Y-axis stop
signal. Where interpolation and dual
operation are combined the effect of the stop command will
depend on where in the cycle the AD71 has reached
(see
below).

Other stop signals
In addition to the four stop signals in Table
6.9, the following
also stop processing while the
AD71 is BUSY. For all the follow-
ing, positioning is decelerated to a stop and the GPP displays an
error message.

Proceed to next address
When a sequence of start data numbers have been specified
with a pointer,
it
will be necessary to zero the system or to
reset the positioning data after
a stop signal i s received.
The above also applies to incremental processing when only
one start number is specified.
Only in absolute address processing can the system proceed
to the next address after a restart.
