Question:  What is Duty Cycle in reference to AC and DC motors?

This is the percent of time a square wave of a fixed frequency is ON (high) versus OFF (low).

So the ratio of operating time of a motor, braking resistor, etc. to its resting time. These drive  parameters are usually is specified in association with the allowable thermal characteristics for the device.

In other words, it would be set to protect the motor and drive from overheating by working them too hard...
