4.5.1 Selection of external scale type
This section describes the selection of external scale type to be used and sets the direction.

Unit Function
- Selects the type of external scale..
0: A, B phase output type
1: Serial communication type (Incremental specification)
2: Serial communication type (Absolute specification)
3 to 6: For manufacturer's use
When the A/B phase output type is connected, if the value is set
to 1, 2 or 6, Err50.0 "External scale connection error protection"
occurs.
Also, when the serial communication type is connected, if the
value is set to 0, Err55.0-55.2 "A-phase or B-phase or Z-phase
connection error protection" occurs.
Err.93.3 "external scale connection error protection" occurs if 1
is set when a serial communication type scale of absolute
specification is connected, if 2 or 6 is set when a serial
communication type scale of incremental specification is
connected, or if 3, 4 or 5 is set as the setting value regardless of
the type of scale connected.
- Sets the direction inversion of the external scale feedback
counter.
