Pr.47
Zero point address
Set the address used as the reference point for positioning control (ABS method).
(When the machine zero point return is completed, the stop position address is
changed to the address set in "
Pr.47 Zero point address". At the same time, the
"
Pr.47 Zero point address" is stored in " Md.29 Current feed value" and " Md.30
Machine feed value".)
Pr.48
Zero point return speed
Set the speed for zero point return.
Note) Set the "zero point return speed" to less than "
Pr.7 Speed limit value". If
the "speed limit value" is exceeded, the "zero point return speed" will be
limited by "
Pr.7 Speed limit value".
