At the middle part of the local control panel, the Back key re-
verts to the previous step or layer in the navigation structure.
The Cancel key cancels the last change or command as long as
the display has not changed. The Info Key displays informa-
tion about a command, parameter, or function in any display
window, providing detailed information when needed. The
four arrow keys are used among menu options by moving the
cursor in the direction indicated. Touch OK to select a parame-
ter marked by the cursor or to enable a parameter change.
Operation keys for local control are found at the bottom of the
control panel (see Fig. 83). Hand On enables control of the fre-
quency converter via the local control panel. Hand On also
starts the motor, and it is possible to enter the motor speed data
by means of the navigation keys. The key can be selected as [1]
Enable or [0] Disable via 0-40 Hand On Key on the local con-
trol panel.
NOTE: External stop signals activated by means of control sig-
nals or a serial bus override a start command via the local con-
trol panel.
The Off key stops the connected motor. If no external stop
function is selected and Off key is inactive, the motor can only
be stopped by disconnecting the mains supply.
Auto On enables the frequency converter to be controlled via
the control terminals and/or serial communication. When a
start signal is applied on the control terminals and/or the bus,
the frequency converter starts.
NOTE: An active HAND-OFF-AUTO signal via digital inputs
has higher priority than the local control keys Hand On –Auto On.
The Reset key resets the frequency converter after an alarm (trip).
