3 HARDWARE 3.1 USER INTERFACE
Once the MM3 has been wired and powered on, it is ready to be programmed for a specific application. Local
programming is done using the front panel keypad and the 40-character alphanumeric display. Remote pro-
gramming via the serial port is also possible using the MM3PC software.
A 40 character display communicates system information to the user. Trip and alarm messages automatically
override the currently-displayed message. If no key is pressed for 2 minutes, a user-selected default messag-
ing sequence will be displayed. If the motor is currently stopped, the Motor Status message will be the default
message. Once the motor is started, the first user-selected message appears.
