9.5.8 Offset value
The offset value is calculated in the preset function and exchanges the position
value for the calculated value�
9.5.9 Scaling parameters
The scaling parameters are used to change the resolution� This parameter only
refers to the output values if the scaling function is enabled�
Parameter
Meaning
Data type
Measuring units
per revolution
Singleturn resolution in steps
Unsigned 32
Total measuring range
in measuring units
Total measuring range
Unsigned 32
If the resolution per revolution is reduced, a skip in the position value may occur when crossing the
physical zero point�
Reason: The position values exceed the real total resolution�
Use the formula below to avoid this problem:
Total resolution = desired measuring steps / revolution x revolutions
9.5.10 Maximum master sign-of-life failures
With this parameter the number of allowed failures of the master's sign of life is
defined�
