Absolute Position Detection for Infinite Length Axes
9-17
( 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.
[ 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.
■
If using the SVA-01 Module
The methods of setting the fixed parameters 36 and 22 differ depending on the SERVOPACK used.
• With SERVOPACKs in the
Σ
series
• With SERVOPACKs in the
Σ
-II series
* 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.
