1. A powered operator system for a fenestration unit, the powered operator system comprising:
an operator motor assembly having an output pulley oriented in a first direction;
an operator assembly having an input pulley oriented in a second direction that is substantially perpendicular to the first direction; and
a drive belt forming a continuous loop extending between the output pulley and the input pulley to operably couple the operator motor assembly to the operator assembly, the drive belt defining a twisted configuration between the output pulley and the input pulley.
