Data Used in the Parameter DB
Address Name Type Initial Value Comment
44.0 REFPT DINT L#0 Reference-point coordinate
52.0 REFPT_TYPE DINT L#0 Type of reference point approach
99.0 REFPT_SPD BOOL TRUE Start speed for reference point approach
0 = rapid
1 = creep
Effects of the Mode
• As soon as travel starts, the synchronization is canceled.
• The actual position is set to the value of the reference coordinate when the
“SYNC” return signal is set.
• The working range is fixed on the axis.
• The individual points within the working range retain their original value, are
however located at new positions.
Aborting the Reference Point Approach
The “reference point approach” mode is aborted in the following situations:
• The drive enable signal is cleared (DRV_EN=0)
• A travel range limit is passed on a linear axis.
