( 4 ) Detailed Descriptions
[ a ] Encoder Type/Encoder Selection/ Absolute Encoder Usage
For an axis performing absolute position detection, set the parameters as shown in the table below.
Model
MP2300
Σ-II and Σ-III Series
SERVOPACK
Σ-I Series SERVO-
PACK
If the abos settings are not used, correct motion control will not be performed. Set the parameters carefully.
Be sure to set both the MP2300 and SERVOPACK parameters.
[ b ] Number of Encoder Resolution
■ If using the SVB-01 Module or the built-in SVB Module
Refer to the following table and set the fixed parameter 36 (Encoder Resolution in Pulses/Resolution)
according to the number of servomotor bits. The settings can be used for all SERVOPACK models.
Number of Bits
■ If using the SVA-01 Module
The methods of setting the fixed parameters 36 and 22 differ depending on the SERVOPACK used.

* 1. This value depends on the setting of Pn212 (PG dividing ratio). The values in the
table are the maximum values.
* 2. Because the maximum value of Pn201 (PG dividing ratio) is 16384, the maximum value
with a 17-bit encoder is also 16384.
