17-71 Position Unit Scale
Default value: 0
Setup: All setups
Data type:
Int8
Enter the scaling factor for the position values. The scaling function multiplies the readout values by 10
parameter. For example, if x = 2, the value 5 is shown as 500. The elements of the array are:
Index 0 is the scaling factor for readout and settings of position values in parameters or in a fieldbus. Index 1 contains exceptions.
l
Index 1 is the scaling factor for readout of position error (parameter 16-08 Position Error) and for the value of parameter 3-08 On

17-72 Position Unit Numerator
Default value: 1024
Setup: All setups
Data type:
Int32
This parameter is the numerator in the equation which defines the relation between 1 motor revolution and physical movement of
machine. Example: Consider a turn table application. The motor makes 10 revolutions when the table makes 1 revolution. The position
unit is a degree. For this setup, enter the following values:
Parameter 17-72 Position Unit Numerator = 360
l
Parameter 17-73 Position Unit Denominator = 10
l
Set the physical unit for position values in parameter 17-70 Position Unit.
