This is how the max torque (MT) values are set for each Puck motor controller:
/* Notes:
* 1 Amp = 1024 puck torque units
* Puck torques are saturated at 8191 by the communications layer
* Cable limits were chosen to be approx 20% of the rated breaking strength
*
* Motor 1 2 3 4 5 6 7
* Stall (Nm) 1.490 1.490 1.490 1.490 0.356 0.356 0.091
* Peak (Nm) 6.31 6.31 6.31 6.31 1.826 1.826 0.613
* Cable limit (Nm) 1.8 1.8 1.8 1.6 0.6 0.6 N/A
* Nm/A -published 0.457 0.457 0.457 0.457 0.236 0.236 0.067
* Nm/A -actual 0.379 0.379 0.379 0.379 0.157 0.157 0.058
* MT value 4860 4860 4860 4320 3900 3900 3200
*
* Example:
* What should the motor 3 Max Torque (MT) be set to in order to not
* exceeed the designed cable limit?
* (1.8 Nm) / (0.379 Nm/A) * (1024 Units/A) = 4863
