Description: System variable/value range/index
$AA_VACTW[X]
Axis velocity in workpiece coordinate system
This variable can only be accessed from synchronized actions
Axes: Channel axis
$AA_VACTM[X]
Axis velocity, setpoint-related in machine coordinate system
Can also be read for replacement and PLC axes
This variable can only be accessed from synchronized actions
Axes: Channel axis
$VA_VACTM[X]
Axis velocity, actual value-related in machine coordinate system
The variable returns an undefined value if the encoder limit frequency
is exceeded
This variable can only be accessed from synchronized actions
Axes: Channel axis
