Local/Remote control button
The LOC/REM button is used for two functions: to quickly access the Control page and to easily
change between the Local (Keypad) and Remote control places.
Control places
The
control place
is the source of control where the drive can be started and stopped. Every control
place has its own parameter for selecting the frequency reference source. In the VACON
®
20 X
drive, the
Local control place
is always the keypad. The
Remote control place
is determined by pa-
rameter (I/O or Fieldbus). The selected control place can be seen on the status bar of the keypad.
Remote control place
I/O and Fieldbus can be used as remote control places.
Local control
Keypad is always used as control place while in local control. Local control has higher priority than
remote control. Switching between Local and Remote Control can be done by pressing the LOC/
REM-button on the keypad.
