If the desired resolution per revolution is less than the really physical resolution per revolution of the
encoder, then the total resolution must be entered as follows:
Total resolution:
Calculation example:
Customer handicap: AU = 2048
Encoder type sign:
PGA=24 bit, PAU=12bit
If the total resolution of the encoder is less than the physical total resolution, the parameter total resolution
must be a multiple of the physical total resolution:
Object 2103h: Preset Value
The preset value is the desired position value, which should be reached at a certain physical position of
the axis. The position value is set to the desired process value by the parameter preset. The preset value
must not exceed the parameter total resolution to avoid run-time errors. If the parameter value exceeds the
total resolution of the encoder a SDO “Out of range” message is generated.

0 Preset Value Unsigned 32 0 rw yes
Object 2104h: Limit Switch, min.
Two position values can be programmed as limit switches. By reaching this value, one bit of the 32 bit
process value is set to high. Both programmed values must not exceed the parameter total resolution to
avoid run-time errors. If the parameter value exceeds the total resolution of the encoder a SDO “Out of
range” message is generated.
