The Control screen (shown below) is used to directly control the drive. It displays vertical bar graphs of the drive’s Speed
Reference and Feedback values, and a Key Function Map that corresponds to the navigation/number keys for drive control.
Press the (Controls) key to display the Control screen.
To navigate from the Control screen to another HIM menu screen, you must always press the ESC soft key to deactivate the Control
screen and display the previous screen.
The HIM can be located in Port 1, Port 2, or Port 3 (default is Port 1). Port 2 and Port 3 can be used for door-mounted or
remote-mounted HIMs. See the following table for parameter 545 [SXX] setup fo
