5.4 Configuration Parameters Description
5.4.1 Operating Parameter
Code sequence:
0 = increasing measured values for clockwise rotation (cw)
1 = increasing measured values for counter-clockwise rotation (cw)
Scaling:
0 = active
1 = not active
Default setting: 0x04 (Scaling: Active, Direction of rotation: CW)

5.4.2 MUR
This parameter sets the desired resolution per revolution. The encoder calculates internally the
corresponding scaling factor. The calculated scaling factor MURF (by which the physical posi-
tion value is multiplied) is calculated according to the following formula:
MURF = Measuring steps per revolution (6001h) / phys. resolution singleturn (6501h)

Only valid if scaling (OperatingParameter bit2) is activated.
NOTICE
MUR and TMR values are only taken into consideration when
scaling is active.
5.4.3 TMR
This parameter sets the total number of measuring steps for singleturn and multiturn. The max-
imum physical resolution is multiplied by a factor. The factor is always < 1. After the scaled total
position of the measuring steps, the encoder resets back to zero.
