Systems and methods can be used in connection with a wellbore environment for automatically controlling wire being spooled around a drum. A system comprising a spooler, a sensor assembly, and a communication link can be used to adjust the position of wire being spooled around a drum. A first motor can control the spooler and a second motor can control the sensor assembly. The spooler can be positioned to control spooling of wire around the drum as the drum rotates to reel in wire. The sensor assembly can be configured to detect a distance between the sensor assembly and the wire being spooled. A communication link can communicatively couple the sensor assembly with the first motor and the second motor to control movement of the spooler and the sensor assembly relative to the drum based on the distance detected by the sensor assembly.
