Feedback 0
10 FB0 Sts
Feedback 0 Status RO 16-bit
Integer
Shows feedback specific errors and alarms for the feedback 0 device.
Bit 0 “Encoder Err” – When set, indicates that a device specific error has occurred. Further detail can be found for each of the following devices:
– Linear Stahl device on Feedback 0, see P27 [FB0 LinStahl Sts] bits 4, 8…14.
– Linear Stahl device on Feedback 1, see P57 [FB1 LinStahl Sts] bits 4, 8…14.
– EnDat device on Feedback 0, see Universal Feedback diagnostic Item 9 [FB0 EnDat Sts] bits 0…6.
– EnDat device on Feedback 1, see Universal Feedback diagnostic Item 15 [FB1 EnDat Sts] bits 0…6.
– BiSS device on Feedback 0, see Universal Feedback diagnostic Item 10 [FB0 BiSS Sts] bits 0, 8…15.
– BiSS device on Feedback 1, see Universal Feedback diagnostic Item 16 [FB1 BiSS Sts] bits 0, 8…15.
– Hiperface device (either feedback, 0 or 1), see diagnostic Item 18 [Hiperface Sts] bits 0…31.
Bit 1 “Msg Checksum” – When asserted, the module has experienced a checksum error while attempting to communicate to an encoder via the serial
communication channel.
Bit 2 “Timeout” – When asserted, the module has experienced a time out condition while attempting to communicate to the encoder via the serial communication
channel.
Bit 3 “Comm” – When asserted, there was an error (except Checksum and Time Out) while attempting to communicate to an encoder via the serial communication
channel.
Bit 4 “Diagnostic” – When asserted, the module has experienced a diagnostic test failure on power up.
Bit 5 “SpplyVltRng” – When asserted, the voltage source to the encoder is out of range.
Bit 6 “SC Amplitude” – When asserted, the Universal Feedback option module has detected that the analog Sine/Cosine (SC) signal amplitude is out of tolerance.
Bit 7 “Open Wire” – When asserted, the module has detected an open wire. The open wire condition for A quad B devices checks that the A, B, and Z signals are in
opposite states to their corresponding NOT signals. Note that when the “A Chan Only” configuration is selected, the B signal will be ignored. If the “Z Chan Enbl”
configuration is not selected, then then the Z signal will be ignored. The open wire condition for sine/cosine devices checks the analog signal levels. An open wire
condition will occur when both the sine and cosine signals are smaller than 0.03V. If only one of the two analog signals is missing, then a “SC Amplitude” error
condition will occur.
Bit 8 “Quad Loss” – Indicates that there is a signal quadrature error.
Bit 9 “Phase Loss” – Indicates that an A or B signal of an A Quad B Incremental encoder was not detected.
Bit 10 “Unsupp Enc” – Indicates that the connected encoder is not supported.
Bit 12 “Encoder Alm” – When asserted, there is an Encoder Alarm.
15 FB0 IncAndSC PPR
Feedback 0 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 0 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
