Total resolution of the encoder
This parameter is used to set the 

requested total resolution� The parameter 

must not exceed the physical measuring 

range of the encoder� The total resolution 

and the resolution per revolution must be 

entered using the following formula:
GA = (PGA x AU) / PAU
PGA 

total physical resolution of the encoder 

(see type label)
PAU 

physical resolution per revolution of the 

enocder (see type label)
GA 

total resolution (customer-specific)
AU 

resolution per revolution (customer-

specific)
If the requested total resolution is lower 

than the total physical resolution, the total 

resolution parameter must be a multiple of 

the physical resolution per revolution�

Preset value

u32, rw

0

The preset value is a position value which 

is to be indicated at a certain physical 

position of the axis� The preset value must 

not exceed the total physical resolution to 

avoid runtime errors�

Two position vaues can be programmed as 

limit switch positions� When one of these 

values has been reached, one of the 32-bit 

position values is set� Both values must not 

exceed the total physical resolution of the 

encoder to avoid runtime errors�

The limit switch (min) sets bit 30 = 1 with the next telegram transmitted when the set position value 

has been reached or fallen below�
