9.2.2 Revolution Direction Specifications
This section explains the direction of revolution for the Servomotor and the encoder respectively.
(1) Servomotor
The Servomotor rotates counterclockwise (forward revolution) when viewed from the load side after a
command to increase a position command is input.

(2) Encoder signal phase
Incremental encoder

Absolute encoder
Forwared revolution ..........Position data incremental output.
Backward revolution .........Position data decremental output.
When C-phase is high, both A- and B-phases cross the low level once every revolution.
