Positioning module IMD20, IMD40
CanOpen protocol
This object can be used to r
1 on the sub-index 1 starts
ealise the offset adjustment of the internal A/D converter. The writing of a
the automatic adjustment. For this, the module has to be in the "Switched
On" (or "Operation Enable") state.
Under the sub-indices 2 and 3, the current offset values can be queried. These are given in units of
32 times the internal A/D converter resolution (11 bit, -1023 ... +1023). It is also possible to directly
write the offset values.
