PURGEMOTION
Purge motion queue in the following manner:
Mode bit
Description
0
Normal Pgen
1
Purge Pgen motion queue
immediately. No deceleration of Pgen
to zero velocity performed.
2
Purge Pgen motion from stick queue.
Decelerate Pgen to zero velocity.
Decel rate is the system Accel value.
3
Purge Pgen motion queue
immediately. No deceleration of Pgen
to zero velocity performed.
Normal Pgen motion after purge.
4
Purge Pgen motion from stick queue.
Decelerate Pgen to zero velocity.
Decel rate is the system Accel value.
Normal Pgen motion after purge.
All other values result in Mode 0. Subsequent
moves are ignored until a zero value is assigned.

XPLC
TRUE to stop the ULTRA Plus or IQ from exe-
cuting its internal I/O logic. Input status will still
be available but no action will be taken on chang-
ing inputs and outputs will be updated only from
host commands. This command is normally used
only by diagnostics.
