Can't read shutdown (892) - DXL Pro

Hi,


We're using the Pros (H series) to build a robot arm and we develop our program using ROS. There are a few times that the motor stops working and we got error message "[RxPacketError] Hardware error occurred. Check the error at Control Table (Hardware Error Status)!" But when we try to read at the Shutdown (48) to find out what went wrong, we can't read this address. It always return "[RxPacketError] Hardware error occurred. Check the error at Control Table (Hardware Error Status)!" back to us. And because the motor was shuted down so we can't not do anything other than hardware reboot (turn off power and turn power back on). And once we do that, all errors are cleared so we never know what happened. According to the manual should we be able to read the detectable situation?


Could you please suggest what can we do? It seems that the motor randomly stop and it starts to happen more often?


Thank you

Hello,


Normally, you should be able to read the error status from Hardware Error Status(892).

Could you show me the instruction you used to read the control table address 892?


Also, please let me know below information

  • Dynamixel SDK version 
  • Controller / Interface hardwares
  • Dynamixel settings(EEPROM area of the control table)


Thank you.
