Axis Operating Input Memory Areas
Section 4-8
When using a G5-series Servo Drive or W-series Servo Drive, the allocation
and polarity of Servo Drive input signals can be set in the Servo Parameters,
but the external I/O status depends on the polarity of the Servo Drive's input
signals, as follows:
The forward rotation limit input (forward drive prohibited signal), and reverse
rotation limit input (reverse drive prohibited signal) are normally-closed con-
tact inputs (N.C. inputs) when polarity is normal. The origin proximity input
(origin return deceleration limit switch), and external latch inputs (1 to 3) are
normally-open contact inputs (N.O. inputs) when polarity is normal.
When using a SMARTSTEP Junior Servo Drive, the following status is shown.
(With the SMARTSTEP Junior, signal polarity is fixed.)

Expanded Monitoring
The PCU has a fixed monitoring function that monitors the following control
information for each axis and returns the result to the Axis Operating Input
Memory Areas.
Axis control status (word b)
Servo status (word b + 1)
External I/O status (word b + 3)
Present position (Feedback present position: Words b + 6, b + 7; Com-
mand present position: Words b + 8, b + 9)
