BECKHOFF AX5000 S-IDN Parameters - Manual (Page 57)

S­IDNs
S­0­0079 Position resolution
This parameter specifies the number of increments per turn (360°) for rotary motors. The LSB of the position
data thus has a weighting of 360° deg / S­0­0079.
For linear motors it specifies the number of increments per pole pitch (e.g. 24 mm). The LSB of the position
data thus has a weighting of 24 mm / S­0­0079.

Related to interface revision changed from 204
In S­0­0076, the AX5000 allows rotary parameter weighting and therefore supports this parameter. Up to
interface 203 the following applies: The scaling cannot be changed. The following settings are set: 2
20 inc/
revolution = 1048576 inc/revolution.
From interface 204 the following applies: The single­turn resolution of the drive can be selected between 20
bits and 30 bits. Example: If the single­turn resolution is set to 22 bits, 10 bits remain for the multi­turn
resolution. The overall resolution is 32 bits.
