Panel Operation
Remote
Local
The ACS 300 frequency converter can be operated from external
controls or directly from the control panel. The panel is an option.
The first time the ACS 300 is connected to the mains, the default
control place is Remote. You can change the control place to
Local (panel control) by pressing and holding the
key down
for three seconds. The associated LED will turn off indicating that
the ACS 300 is not under remote control.
When the
key is pressed, the associated led will turn on
indicating that the ACS 300 is under remote control. The
ACS 300 is then controlled from the devices connected to the
terminal block X1 on the Control Card.
Operation can be changed from Remote to Local in two ways.
The first method allows you to transfer running information from
external devices to the control panel while the ACS 300 is
operating and without interrupting operation.
Press and hold the
key and the
key simultaneously for
three seconds. This will transfer the current external reference to
Page 1 parameter REF FREQ/LOC FREQ. For example, if the
drive is running in reverse at 45.7 Hz reference from the
analogue input, the panel frequency reference will now be
45.7 Hz. The panel direction will be reverse and the panel run
status will be run. The operator can now change the frequency,
direction and run status of the drive from the control panel.
If only the
key is pressed, the motor stops and the analogue
input reference value REF FREQ is transferred to LOC FREQ.
Note! Constant speed reference is also transferred. The motor
can be started from the control panel within the limits established
by parameter settings.
