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.

Abstract: The present invention relates to drive controllers as used in machinery drives, for motor control and the like. In particular the present invention relates to a drive controller operator interface and serial protocol therefor. Electric motors and other electrical devices are typically controlled by inverters which convert input power to control input signals for the motor or other electrical device. Since controllers for inverters include keyboard controls and LED/LCD displays, it has been found that the controllers represent a significant cost of the inverters. To overcome this or for other reasons such as overall control integration, inverters have been remotely controlled by software using cabling operated on RS232 protocols or similar. The present invention seeks to overcome some of the problems which arise in the implementation of an alternative type of system having a removable keypad/display unit controller which can serve a number of drives.
