Set the resolution of A quad B encoder in Pn192, Pn193. Note that the value in
Pn192 should be set as the physical (optical) resolution, excluding the x4
multiplication done by the driver internally.

Set the direction of electrical phase. This parameter is used to find the electrical
phase in the AB encoder (other than Yaskawa); if you don’t know the direction,
just set unknown direction and FSP Amplifier will find it automatically.

As mentioned before, the new parameter settings become active only after the
driver has been restarted.
