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 approx-
imately 40ms.
Note: 1.
The absolute position data within one revolution is the value before dividing.
2.
Absolute position data increases during forward rotation. (Not valid in reverse rotation mode).
Incremental Pulses and Origin Pulses
Just as with normal incremental pulses, initial incremental pulses which provide
absolute data are first divided by the frequency divider inside the Servo Amplifier
and then output.
