Chapter 6 - Control and Parameter Logic
Panel Operation 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 input power, the default control location is Remote. You
can change the control location 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.
Remote
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.
Local
Operation can be changed from Remote to Local in two
ways. The first method allows you to transfer running infor-
mation 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 ref-
erence to Page 1 parameter REF FREQ/LOC FREQ. For
example, if the drive is running in reverse at 45.7 Hz refer-
ence from the analog 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 ana-
log 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.
