WORDS
PURGEMOTIONACTIVE
Motion Purged
System
Purpose
Flag to indicate a purge motion request is being processed.
Syntax
variable = PURGEMOTIONACTIVE
variable
The variable will be set to ON or OFF. This is a read-only system
flag that signals motion queue purging is complete.
Remarks
FALSE (OFF) indicates that zero velocity has been reached. If decelerating to zero
velocity, this flag will be ON until Pgen motion is no longer changing and all associ-
ated final position quantities have been assigned.

Example
F1 = PURGEMOTIONACTIVE
if (F1 = ON)
{
;perform other motion program functions while
;Pgen motion is being purged.
}
PVEL1
Peak Motor Velocity
Velocity
Purpose
Peak velocity in user units per Timebase.
Syntax
variable = PVEL1
variable
The variable may be a nonvolatile variable Gn, a volatile vari-
able Vn, or a system variable.
Remarks
The motor velocity is measured every velocity loop update (1mS). If the present value
is greater than the previous peak, the value is saved as the new peak. The magnitude of
the peak is calculated based on an absolute value of VEL1. The value is saved and
reported as a signed number, however. CLRPEAKS resets this value to zero.
