Class 2 32‐Bit resolution, Input/Output consistent:
The encoder uses 2 input words and 2 output words, which are each consistently transmitted over the bus.
Class 2 32‐Bit resolution, Input consistent:
The encoder uses 2 input words, which are each consistently transmitted over the bus.
Class 1 16‐Bit resolution, Input/Output consistent:
The encoder uses 1 input word and 1 output word, which are each consistently transmitted over the bus.
Class 1 16‐Bit resolution, Input consistent:
The encoder uses 1 input word, which is consistently transmitted over the bus.
Combination with:
Class 2 32‐Bit resolution, Input consistent Speed in (units/s) or
Class 2 16‐Bit resolution, Input consistent Speed in (rpm)
The encoder uses max. 2 input words, which are each consistently transmitted over the bus.
Default setting Scaling on, 25 Bit total resolution
Class 2 32‐Bit resolution MUR=13Bit,TMR=25Bit:
Preset setting
In the mode 'Class 2' the encoder can be adjusted over the PROFIBUS to any position value in the value range of
27 Bit or 15 Bit. This occurs by setting the most significant bit (MSB) of the output data (2^31 for configuration
Class 2 ‐ 32 Bit or 2^15 for configuration Class 2 ‐ 16 Bit).
The Preset Value that is transmitted in the data bytes 0 ‐ 3 is accepted as the position value with the rising edge
of Bit 32 (=Bit 7 of data byte 3). The encoder then continues counting from this position. A new adjustment is
then only possible after the control bit has been reset. There is no acknowledgment of this action via the inputs.
Speed values
All modules can be combined with the configuration of an additional Speed value. The input words are increased
to a maximum length of 8 Bytes (64 Bit) depending on the configuration of the speed value. The Speed value is
signed and depends on the count direction.
Positive values in CW, negative in CCW direction.
