Universal Feedback
Feedback 1
45 FB1 IncAndSC PPR
Feedback 1 Incremental and Sine Cosine Pulses Per Revolution
Indicates the Pulses Per Revolution (Encoder Lines) of the SinCos or A Quad B encoder for
the feedback 1 device.
For the following selections, PPR is automatically read from the encoder:
• EnDat SC
• BiSS SC (not manually configured)
• Hiperface SC
For the following selections, PPR has to be entered by the user:
• BiSS SC, Manually configured
• Gen SinCos
• A Quad B

Feedback 1 Incremental Configuration
RW 16-bit
Integer
Configures Incremental Feedback for the feedback 1 device.
Bit 0 “Z Chan Enbl” – When set, Channel Z is also monitored for Phase Loss. When cleared, Channel Z is ignored for Phase Loss detection.
Only used if [FB1 Device Sel] = “Inc A B Z.”
Bit 1 “A Chan Only” – When set, logic monitors only channel A. When clear, logic monitors both A and B.
Bit 2 “Edge Mode” – When set, speed calc uses AB edge data. When clear, speed calc does not use AB edge data.
Bit 4 “Single Ended” – This bit has to be set if the connected A Quad B encoder has single ended signals. For these encoders, the Phase Loss detection is switched off.

RO 16-bit
Integer
Displays Incremental Feedback status for the feedback 1 device.
Bit 0 “Z Chan Enbl” – Indicates that Channel Z is monitored for Phase Loss. Only used if [FB1 Device Sel] = “Inc A B Z.”
Bit 1 “A Chan Only” – Indicates only A channel is monitored, B channel not used.
Bit 2 “A Input” – State of encoder A input signal
Bit 3 “A Not Input” – State of encoder A Not input signal
Bit 4 “B Input” – State of encoder B input signal
Bit 5 “B Not Input” – State of encoder B Not input signal
Bit 6 “Z Input” – State of encoder Z input signal
Bit 7 “Z Not Input” – State of encoder Z Not input signal
