5.1.3 Resolution reference
This parameter is used to specify what the "desired measurement steps" that are
entered should refer to (see section 5.1.2):
• Revolution
• maximum overall resolution
• Physical measurement steps
Desired resolution per revolution
In this case the position value is set in such a manner that it is incremented by the
number of desired measurement steps for each revolution. In addition, in this case the
"Overall resolution" parameter is evaluated. It can be used to adjust the measurement
range (see section 4.1.6).
Desired resolution per maximum overall resolution
The desired measurement steps that are entered refer to the entire measurement
range of the device, i. e. the device generates the number of measurement steps
assigned by parameter over the entire (physical) number of revolutions.
Desired resolution per physical measurement steps
In this case, the desired number of steps refers to the physical measurement steps
entered with the "Physical measurement steps" parameter (see also section 5.1.7). In
this context, physical steps means the numeric value that is read internally from the
code disk by the rotary encoder (for example 4,096 steps per revolution for the
standard 12 bit version). Gear factors can be freely set with this option.
