Motor Data Description: The standard 8720SM Motors have assigned 8720SM catalog numbers. Parameter 777 provides a
list of the available standard 8720 motors. If the motor catalog number does not appear on the list “custom” must
be entered and all motor specific parameters must be entered individually. For standard MPL-B8xxx, -B9xxx, and
8720SM motors this parameter is set by the data stored in the encoder and cannot be changed unless the
feedback is disconnected and power recycled.

Motor Data Description: The 8720MC can be used with several different types of motors. Parameter 778 identifies the type
of motor the 8720MC is connected to. The possible enumerations are:
* 000 - Rotary PM Brushless
* 001 - Rotary Induction
* 010 - Rotary Induction Dual Winding
* 011 - Linear PM Brushless
* 100 - Linear PM Brushless AC Ironless
