directly in the Local mode.

Loc/Rem function.
Press one second to go directly to change the language.
Press and hold the key for more than five seconds to switch
between Local and Remote function. When editing values,
the key can be used to change the sign of the value.
LOCAL MODE
Local mode is used for temporary operation. The actual status
of the frequency inverter will not change, e.g. Run/Stop condi-
tions and the actual speed will remain exactly the same. When
the frequency inverter is set to Local operation, the display will
show L in area B in the display. In local mode Econet funticons
are deactivated. The Econet A-alarm handling is still active
where all A-alarms trip the frequency inverter.
The frequency inverter will be started and stopped using the
keys on the control panel. The reference signal can be controlled
using the + and - keys on the keyboard. This can be done on
frequency inverter page 310.
REMOTE MODE
When the frequency inverter is switched to REMOTE operation,
the frequency inverter will be controlled according to Econet
control methods.
RUN L: Not used
STOP/RESET:
Stops the motor or resets the
frequency inverter after a trip
RUN R: Gives a start with right rotation
