The frequency converter does not react to any
control signal until [Auto On] or [Hand On] is
pressed.
The frequency converter is controlled from the
control terminals and/or the serial communi-
cation.
Control the unit via the navigation keys on
the LCP. Stop commands, reset, reversing, DC
brake, and other signals applied to the control
terminals can override local control.
The speed reference is given from external
signals, serial communication, or internal
preset references.
The frequency converter uses [Hand On]
control or reference values from the LCP.
