1. A method of operating a door operator coupled to a door, wherein the door operator comprises a motor operable to move the door in at least one direction and a controller operable to control the motor, the method comprising:
performing a calibration procedure, the calibration procedure comprising:
with the door at a first position and the door having an initial speed of zero, initiating, by the controller, measurement of a time duration;
in response to the door reaching a threshold speed different from the initial speed, ceasing, by the controller, measurement of the time duration; and
determining, by the controller, a maximum speed based upon the time duration, wherein the maximum speed is a maximum allowable speed for the door; and
subsequent to the calibration procedure, performing at least one operation based upon the maximum speed.
