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.
