Joint motion error

[55155]

Hello,

In Genesis, my asset shows unusual movement. The currently active joint is a motor, and the other joints have zero velocity. Could you provide comments on why this phenomenon might be occurring?

Code reference: force_command = np.array([crank_torque, 0, 0])

TEST.py

scale : 1.0

I checked the torque output, and the values are very large. Why is this happening? Even the passive joint has very large values.

Should I post it in the GitHub Issue tab, not the Discussion tab
