External control
When the drive is in external control, the commands are given through the standard
I/O terminals (digital and analog inputs) and/or the fieldbus interface. In addition, it is
also possible to set the control panel as the source for the external control.
External control is indicated with REM on the panel display.
The user can connect the control signals to two external control locations, EXT1 or
EXT2. Depending on the user selection, either one is active at a time. This function
operates on a 2 ms time level.
