Holding torque
The continuous torque, and the corresponding continuous electrical current, a motor must supply to keep a joint from moving under a static load, most commonly gravity, even when the joint itself is not producing any new motion. Holding torque is frequently an underestimated fraction of a robot's total power draw and a primary target for mechanical intelligence.
Defined in 2 GAGE programs, which carry 2 distinct definitions of it. The wording above is taught in Engineering Judgment and Professional Formation.
How each discipline defines it
The same term does different work depending on who is using it. These are the definitions as each program teaches them, unedited.

The maximum torque a stepper motor can resist without the rotor moving away from the energized step position. Measured with rated current applied to both windings simultaneously. Holding torque is the peak torque value on the motor datasheet; available torque at speed is always lower.
