Overview of Version 1 Upgrades Section 1-12
Application Precautions
• If an axis connected to a motor and encoder is temporarily used as a vir-
tual axis, there will be a discrepancy between the real axis position and
the position controlled in the MC Unit when the axis is returned to use as
a normal axis. Therefore, set the origin before using the axis as a normal
axis.
• An error may occur if the power is turned ON with no CW limit input, CCW
limit input, emergency stop input, or alarm input signal connected.
• When an absolute encoder is connected, the origin will remain undeter-
mined if a virtual axis is set without a servo-lock after the power is turned
ON. In that case, use the present position preset to determine the origin.
• For an axis specified as a virtual axis, it is not possible to change the ini-
tial setting for encoder polarity in the mechanical specifications parame-
ters from forward rotation for encoder increase.
1-12-1-2 Electronic Gear Function (CONNECT)
Overview
This function moves an operating axis in sync with the input axis while apply-
ing a specified gear ratio (numerator/denominator). The operation is similar to
a roller connected to a gearbox.
For the input axis, a sync encoder input, MPG input, encoder feedback input
(X, Y, Z, or U), virtual axis position command value (X, Y, Z, or U), or real axis
position command value (X, Y, Z, or U) can be specified.

Sets 00000006 hex in
D00000 and D00001
(i.e., only the U axis is
a virtual axis).
Uses 1840 hex for the
control data, and writes
the virtual and real axis
settings to the MC Unit
(example: Unit #0).
