Note
Please note the following:
Bit 2
0
of the number of revolutions is fixed on the 12th cycle, followed on the 13th cycle by
the most significant bit of the number of increments/revolution.
The leading and subsequent data bits transmitted by the encoder (or zeros) are not
evaluated by SIMOTION C.
The encoder used in the example should be configured as follows:
– Encoder pulses per revolution: 256
– Data width: 16
– Message length: 21 bits (or 25 bits)
– Message profile: Fir tree
