Remote Control - ABB ACS 140 Programming Manual

Remote Control

When the ACS 140 is in remote control (REM), the commands are given
primarily through digital and analogue inputs, although commands can be
given also through the control panel or serial communication.
Parameter 1102
locations 1 and

reference, or a process reference, depending on the application macro
selected.
In remote control, constant speed operation can be programmed by
