In general the resolution of an EnDat feedback device will be taken automatically from the device and calculated based on the motor settings.
In some case it could be needed that the resolution needs to be adopted.
In this case this can be done in the following way:
FB1.ENCRESSOURCE 0 -> 1 this setting will enable the option to manually set FB1.ENCRES
If the precondition FB1.ENCRESSOURCE 1 is full filled you an setup the resolution for FB1.ENCRES based on your mechanics.
