Unfortunately, the HBL1696 controller does not have current sensors on its motor outputs. It can estimate motor current on this controller by measuring the current draw from the power supply. There are some caveats to doing this, outlined on page 146 of our
User Manual
in the section about the limitations of Torque Mode.
The Serial command to get motor amps is
?A. It is documented on page 238 of our
User Manual
