8.2 Status Message Definitions

Table 8.1 to Table 8.3 describe the shown status messages.
Off The frequency converter does not react to any
control signal until [Auto] or [Hand] is pressed.
Auto The frequency converter is controlled from the
control terminals and/or the serial communi-
cation.
Hand Control the unit via the navigation keys on
the keypad. Stop commands, reset, reversing,
DC brake, and other signals applied to the
control terminals can override local control.
Table 8.1 Operating mode
Remote The speed reference is given from external
signals, serial communication, or internal
preset references.
Local The frequency converter uses [Hand] control
or reference values from the keypad.
