I am using 5 Dynamixel XM430-W350T motors for my application. Controller used : OpenCM9.04 + EXP board.
To read the current consumed by each motor during operation, i am reading the PRESENT CURRENT register repeatedly. Two tyings i noticed are :
1. Sometimes the current values in negative for atleast two of the motors. though i do not see any visible problems, should i be concerned about this? What is the significance of -ve current?
2. In few modes, two motors are not used and remain stationary (but connected to power).But the current log shows they are drawing power. Is that normal?
Thanks in advance.
