If the 500 P/R encoder of the PB Series is switched to 10,000 divisions, is the resulting positioning resolution guaranteed?

However, because microstepping is realized through current control, the selected resolution
is not mechanically guaranteed. The mechanically guaranteed positioning resolution remains 200 P/R, which corresponds to the fundamental step angle of a 2-phase stepping motor.

For the PB4, the position correction function provides positioning accuracy within ±1/4 step.
