A critical error occurred during Brake Release
Try the following actions to see which resolves the issue: (A) Conduct a complete rebooting sequence, (B) Ensure the mounted payload, TCP, and CoG matches your configuration
C284A1 Brake release procedure aborted.
C284A2 Microprocessor B wasn't ready.
C284A3 Absolute position unknown, after successful completion of the find absolute position movement.
C284A4 The motor did not move enough, during the find absolute position movement.
C284A5 After successfully completing the free pin move the rotor was still not within the required window.
C284A6 The motor was unable to move far enough during the free pin movement.
C284A7 Peak speed of {float} rad/s was detected during enabling of motor control.
C284A8 Speed was larger than 0.1 rad/s for more than 50ms, during enabling of motor control.
C284A9 Motor control was not successfully started, due to lacking commutation offset calibration.
C284A10 Absolute position was not known before attempting to release the brake pin.
C284A11 Motor was not within the free pin window after enabling of control.
C284A12 Brake release commutation was started while motor control was running.
C284A13 Pin collision detected, during brake release move.
C284A14 Brake release commutation did not move far enough.
