1. A hydraulic tool that performs a crimp on a workpiece, the hydraulic tool comprising:
a tool head including a jaw operable to move to crimp the workpiece;
a piston coupled to the tool head;
a motor to drive the piston to move the jaw;
a sensor configured to sense a condition over a stroke of the piston; and
a controller in communication with the sensor, the controller being configured to run the motor until the jaw is in a closed position,
wherein the controller
receives sensor information from the sensor;
determines, based on the sensor information, a crimp profile over the stroke of the piston; and
determines, based on the crimp profile, a characteristic of the crimp performed on the workpiece.
