APPENDIX
Local Control vs. Remote Control
The ACS140 can be controlled from two remote control locations or from the
control panel. Figure 23 below shows the ACS140 control locations.
The selection between local control (LOC) and remote control (REM) can be
done by pushing the MENU and ENTER buttons simultaneously.
Figure 23 Control locations.
Local Control
The control commands are given explicitly from the control panel when the
ACS140 is in local control. This is indicated by LOC on the control panel
display.
Parameter 1101
KEYPAD REF SEL is used to select keypad reference, which
can be either
REF1 (Hz) or REF2 (%). If REF1 (Hz) is selected, the type of
reference is frequency and it is given to the ACS140 in Hz. If
REF2 (%) is
selected, the reference is given in per cent.
If PID Control macro is used, reference
REF2 is fed directly to the PID
controller as percentage. Otherwise, reference
REF2 (%) is converted to
frequency so that 100 % corresponds to
MAXIMUM FREQ (parameter 2008).
