bit 0~15: Position comparison x; bit 16~31: Position comparison y
Please refer to Pr3.74
Working principle
 Enable position comparison Pr5.70
Position comparison function enabled when Pr5.70 is set to 1. Comparison status will
be updated as position comparison starting point. When Pr5.70 is set to 0, position
comparison ends and status clears.
 Single position comparison
Position comparison ends right after 1
value will be reset to 0. Function only enables after position comparison enabling
signal is detected. The actual position feedback Pr5.80 is absolute and added on top
of the previous comparison, will not be reset to zero.
 Cycle comparison
Position comparison does not end right after 1
comparison value will be set as position comparison starting point. Actual position
feedback Pr5.80 will be cleared after every comparison. Under cycle comparison,
target position is relative increment. After previous comparison, actual position
feedback will be cleared and restart counting, in comparison with new target position.
 N Cycle comparison
Number of cycles is set in Pr5.83. When the number of cycles set reached, position
comparison function is turned off.
 Position comparison output width Pr5.72
When position comparison condition(s) fulfilled, output can be delivered through DO or
frequency divider ABZ/OCZ signal. Signal pulse width can be set in Pr5.72. Please
make sure the output signal width is less than the travel between 2 target positions.
 Position comparison target position
42 target positions. Target position value and its corresponding attributes can be set in
Pr3.32~Pr3.94.
 Position comparison starting point Pr5.74
Indicates the first comparison point. For example, if Pr5.74 is set to 5, position
comparison will start from 5
 Position comparison end point Pr5.75
Indicates the last comparison point. For example, if Pr5.75 is set to 7, position
comparison will stop at 7
