Abstract

An encoder reset device and method that allows for an encoder to be reset and/or recharged at virtually any location. A reset device and method of the present invention also allows the reset/charging process to take place simultaneously with the removal of an encoder-equipped device that is being replaced, as a device of the present invention does not require the use of an encoder-equipped device controller to perform the reset/charging process.
