l Three types of position scale are available. The user may select a type suited for own application.
The PS command selects a type of the scale.
Table 7-19: Parameter PS and type of position scale

1 Linear position scale
l This position scale extends linearly from the home position in both plus and minus directions.
l The position data ranges from – 2 147 483 648 to + 2 147 483 647 [pulses] with the home
position at 0. In case of the counting position data increases in the plus direction, it changes to
-2 147 483 648 [pulse] when it exceeds +2 147 483 647 [pulse]. In case of the counting direction
decreases in the minus direction, it changes to +2 147 483 647 [pulse] when the reading exceeds
-2 147 483 648 [pulse].
