BEI Sensors MHK5 Absolute Hollow Shaft Encoder - Manual (Page 38)

Version 07/10 BEI Sensors CANopen Manual serie M 38
This parameter is used to program the desired number of measuring units over the total measuring range.
This value must not exceed the total resolution of the absolute rotary encoder, which is printed on the type
sign of the encoder.
Attention:
Following formula letter will be used:
PGA Physical total resolution of the encoder (see type sign)
PAU Physical resolution per revolution (see type sign)
GA Total resolution
(customer parameter)
AU Resolution per revolution
(customer parameter)
Please use the following formula to calculate the total resolution of the encoder:
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
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.
