When changing TMR /MUR, the system also checks the TMR/MUR ratio.
If TMR is set to a value that leads to an invalid ratio, an error message is returned via Encoder-
DiagData and the new value is rejected. The old value remains active in the encoder. Only valid
if scaling (OperatingParameter bit2) is activated.
NOTICE
MUR and TMR values are only taken into consideration when
scaling is active.
5.4.4 Preset Value
The position value of the encoder is set to the preset value input. This allows e.g. aligning the
zero position of the encoder with the zero position of the machine.
The PresetValue value must be smaller than the TMR value set.

5.4.5 Preset Enable
The position value of the encoder is set to the preset value defined in PresetValue if PresetEn-
able has the value 1. For all other PresetEnable values, the value defined in PresetValue is ig-
nored.
This allows e.g. aligning the zero position of the encoder with the zero position of the machine.
NOTICE
Simultaneous baud rate change
Please note: If PresetEnable has the value 0x01, BaudRate must be
set to 0xFF, since a simultaneous baud rate change and setting of
the preset value in the same config datagram is not supported by the
encoder.
