Detailed Signal Specifications
PAO Serial Data Specifications
The number of revolutions is output in five digits.
Note: 1. Data is “P+00000” (CR) or “P-00000” (CR) when the number of revolutions is zero.
2. The revolution range is “+32767” to “-32768.” When this range is exceeded, the data changes
from “+32767” to “-32768” or from “-32768” to “+32767”
PSO Serial Data Specifications
The number of revolutions and the absolute position within one revolution are
always output in five and seven digits, respectively. The data output cycle is
approximately 40ms.
