* This feedback device provides very low resolution feedback and should not be used for applications requiring a high level of performance.
Due to the low resolution of UVW communication only encoders, it is recommended that the P1 Feedback Filter (03.042) is set to its maximum value.
A value of 1 ms to 2 ms may also be required in the Current Demand Filter (04.012) and it is also recommended that the speed loop gains are set to
a low value to obtain stable operation.

SC Hiperface (7) for a Sincos encoder with Hiperface serial communications
EnDat (8) for an EnDat communications only encoder
SC EnDat (9) for a Sincos encoder with EnDat serial communications
BiSS (13) for a BiSS communication only encoder
5 V (0), 8 V (1) or 15 V (2)
Auto-configuration is enabled at default and automatically sets up the following parameters.
Rotary Turns Bits (03.033)
Rotary Lines Per Revolutions (03.034)
Comms Bits (03.035)
These parameters can be entered manually when Pr 03.041 is set to Disabled (0).
