PURGEMOTION Purge Motion Motion
Purpose This read/write variable will immediately remove the active Pgen motion. Control of
deceleration and subsequent Pgen motion are dependent on the variable value.
Syntax variable = PURGEMOTION
variable The variable defines which of the purge mode states is valid. The
numbers corresponding to the variable modes are shown below.
Value Description
0 Normal Pgen motion in effect.
1 Purge Pgen motion immediately.
No deceleration of Pgen to zero velocity performed.
2 Purge Pgen motion immediately.
Decelerate Pgen to zero velocity.
Decel rate is the system Accel value.
3 Purge Pgen motion immediately.
No deceleration of Pgen to zero velocity performed.
Pgen motion in effect after current motion is purged.
4 Purge Pgen motion immediately.
Decelerate Pgen to zero velocity.
Decel rate is the system Accel value.
Pgen motion in effect after current motion is purged.
Remarks All other values assigned to this variable will result in mode 0 being assigned. When
PurgeMotion is non-zero, all subsequent move type statements will be ignored until a
value of zero is assigned.
This command is intended for use in an Fkey routine, an Xkey routine, or a scanned
event. Use in the main program thread is discouraged.
