5.81.3 64 bit encoder signal evaluation
This function extension will be available from library V01.03.xx.xx!
If "1: 64 bit encoder signal" has been selected in C05271, the dnEncoderIn2 input is evaluated in ad-
dition to the dnEncoderIn input for the second encoder signal:
• The position (number of increments) is transmitted within a revolution via the dnEncoderIn in-
put. The position has a fixed resolution of 32 bits.
• The current number of encoder revolutions is transmitted via the dnEncoderIn2 input.
• The (multiturn) resolution for the dnEncoderIn2 input is set in C05274.
• C05273 (singleturn resolution) is inactive in this mode (is not evaluated).
 How to convert encoder information / an encoder position from encoder input X8 into a _p
position of the internal measuring system:
1. Connect the ENC_dnEncoderOut1 output of the LS_EncoderX8 system block to the
dnEncoderIn input.
2. Connect the ENC_dnEncoderOut2 output of the LS_EncoderX8 system block to the
dnEncoderIn2 input.
3. Select "1: 64 bit encoder signal" in C05271 to ensure that the second input, dnEncoderIn2,
is also evaluated.
4. Set the resolution of the multiturn encoder in C05274 (maximum number of revolutions).
