ZERO POINT INITIALIZATION
—
SET START nTH AXIS
[Function]
This is used to set a random position as the origin during zero point initialization using the marked
point alignment method in the absolute position detection system.
[Operation]
This signal turns ON when a random position is to be used as the zero point after moving the
relevant axis in the zero point initialization mode.
Refer to the section on "Zero point initialization set complete (ZSFn)" signal for details on the
operations.
(Note 1) This signal is a function signal for zero point initialization, and is not a signal that selects
the operation mode. Select the jog mode or handle mode to move the axis to a required
position.
(Note 2) This signal is valid for the following specifications.
When servo detection specification (motor detector, servo system) is the absolute
position detection system.
When "TYPE" on the [ABS. POSI PARAM] screen is set to "2".
(Note 3) This signal will be invalid in the following states.
During emergency stop
During reset
When the "Zero point initialization set start (ZSTn)" signal is turned ON before the "Zero
point initialization set mode (AZSn)" signal. In this case, turn this signal OFF once, and
then turn it ON again.
When the grid (Z-phase signal provided per motor rotation) has not been passed once
after the power is turned ON.
