Drive controller operator interface and serial protocol
First Claim
Patent Images
1. A drive controller and operator panel operable to control a drive that supplies motive power to a device;
- wherein;
the operator panel is removable with respect to the drive controller, and includes data input means and a first data transfer port;
the drive controller is operatively connected to the drive and includes a second data transfer port which cooperates with the data transfer port of the operator panel to enable the drive controller and the operator panel to communicate control data by means of a serial protocol;
said operator panel is alternatively connectable to a plurality of drive controllers via said first data transfer port, for controlling differing types of devices; and
the serial protocol includes data indicating the device type of the device transmitting the data.

Abstract
A drive controller operator interface and serial protocol therefor are provided for controlling electric motors and other electrical devices which are typically powered by inverters that convert input power to control input signals for the motor or other electrical device. The system includes a removable keypad/display unit controller which can serve a number of drives, as well as an improved serial protocol, that includes a provision for data indicating the type of device to which the drive is attached.

13. A system for controlling operation of a device, comprising:
-
a drive unit that supplies motive power to said device;
a drive controller operatively connected to the drive unit and having a first data transfer port; and
an operator panel which is detachably connectable to said drive controller, and which includes data input means and a second data transfer port which cooperates with said first data transfer port for communication with said drive controller when said operator panel is connected thereto;
wherein,said operator panel communicates control data to said drive controller, by means of a serial protocol, for controlling said drive unit;
said operator panel is alternatively connectable to a plurality of drive controllers via said first data transfer port, for controlling differing types of devices; and
said serial protocol includes data indicating the type of device to which the drive controller is connected.
