Table 6.11 MC_ReadMotionState_ISD51x
6.5.4.11 MC_ReadActualPosition_ISD51x
This function block provides the value of the actual
position if Enable is set (see chapter 7.7.5 Parameter 50-03:
Position Actual Value (0x6064)). Valid is TRUE when the data-
output Position is valid. If Enable is reset, the data loses its
validity and all outputs are reset, regardless of whether
new data is available.
The output Position is a signed value.
The output data is available immediately.

Velocity is constant.
Velocity may be 0. For the
actual value, a window is
applicable, see
chapter 7.22.3.1 Parameter
51-70: Constant Velocity
Window (0x2030) and
chapter 7.22.3.2 Parameter
51-71: Constant Velocity
Window Time (0x2031).
Velocity is constant and
value 0.
Increasing the absolute
value of the velocity.
Decreasing the absolute
value of the velocity.
The position is increasing.
The position is decreasing.
An internal limit is active.
