Feedback 0

16

FB0 Inc Cfg
Feedback 0 Incremental Configuration

RW 16-bit

Integer

Configures Incremental Feedback for the feedback 0 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 [FB0 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.

FB0 Inc Sts
Feedback 0 Incremental Status

RO

16-bit
Integer

Displays Incremental Feedback status for the feedback 0 device.

Bit 0 “Z Chan Enbl” – Indicates that Channel Z is monitored for Phase Loss. Only used if [FB0 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

FB0 SSI Cfg
Feedback 0 SSI Configuration

RW 16-bit

Integer

Configures the communication to a SSI encoder for the feedback 0 device. Transmission format: [MSB...Position...LSB], [Error Bit]*, [Parity Bit]*.

Bit 0 “Parity Bit” – If set, SSI encoder has to support a parity bit (even parity).
Bit 2 “Gray Code” – Enables the gray to binary conversion of the position.
Bit 3 “Err Bit Enbl” – If set, there is an error bit transmitted by the encoder.
Bit 4 “DblWordQuery” – If set, a Double Word Query is executed at startup which means that the same position is transmitted twice by the encoder. If the two
positions are not identical, the “Comm” error bit in [FB0 Sts] is set. This bit only needs to be cleared if the encoder does not support Double Word Query and it does
not send zeros instead of the second position (which it actually should according to the SSI specification).
