(3) Precautions
(Note 1) to (Note 7) in sections (1) and (2) correspond to the following items.
1) The current limit value (%) can also be set with servo parameter "160014 SV014". The
excessive error width can be set with servo parameter "160053 SV053".
2) The Abs posn set menu key on the Zero point set screen cannot be turned OFF on the
screen. This menu will turn OFF when the power is turned ON again. Automatic operation and
zero point return cannot be carried out while this menu is ON. (An error will occur.)
3) If "270005 No stopper" is "1", set it to "0" before setting "1 Ref position set".
4) Before carrying out zero point initialization, the Z-phase grid point must be passed once after
the power is turned ON. If the grid point is not passed even once after the power is turned ON,
the message "AX0104 Some ax does not cross Z phase" will appear when the current limit is
reached. In this case, return one or more grid back, and repeat the procedures from step 6.
5) When the grid mask amount (zero point return parameter "150005 Grmask") is set and the
grid mask amount is larger than the distance from the machine end stopper to the grid point,
the next grid point will be the absolute position basic point.

6) When carrying out initialization of the dogless-type absolute position, the reference point shift
amount (zero point return parameter "150003 G28sft") is invalid.
7) When zero point initialization is carried out, the data required for absolute position detection is
saved as parameters. Thus, back up the data.
