C296A5 Phase 2 is not connected. Diagnostic data: {hex}

Bit pattern 0b1010 indicates that phase 2 is not connected

Try the following actions to see if it resolves the issue: (A) Make sure all Motor phases are connected correctly, (B) Update software

C296A6 Phase 3 is not connected. Diagnostic data: {hex}

Bit pattern 0b0010 indicates that phase 3 is not connected

Try the following actions to see if it resolves the issue: (A) Make sure all Motor phases are connected correctly, (B) Update software

C296A7 Motor test results were invalid. Diagnostic data: {hex}

Bit0 high indicates short circuit. Bit1 is phase 3 test. Bit2 is phase 2 test. Bit3 is phase 1 test

Try the following actions to see if it resolves the issue: (A) Make sure all Motor phases are connected correctly, (B) Update software

C296A8 Motor PWM output is not zero in Joint State {unsigned}

No PWM signals are expected to be active in the current Joint State.

 

C296A9 Robot Voltage was present during self-diagnostics

Robot Voltage rose above acceptable levels before both processors powered it on

 

C296A10 Time out during self-diagnostics

A processor timed out while waiting for the other processor to finish self-diagnotics

 

C296A11 Data was received while trying to disable communication

A validation that theof communication could be suppressioned failed to preventin preventing a message from passing through.

 

C296A12 Sequence number did not match expected sequence

After communication was disabled and reenabled the sequence number did not match what was expected

 

C296A13 The expected sequence number was {unsigned}

After communication was disabled and reenabled the sequence number did not match what was expected

C296A14 The actual sequence number was {unsigned}

After communication was disabled and reenabled the sequence number did not match what was expected

 

C296A15 Interval between messages did not match expectations

After communication was disabled and reenabled the message interval did not match what expectations

C296A16 The expected interval was {unsigned} ticks

After communication was disabled and reenabled the message interval did not match what was expected

 

C296A17 The measured interval was {unsigned} ticks

After communication was disabled and reenabled the message interval did not match what was expected

 

C296A18 Motor Kt value {float} is outside manufacturer specifications
