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.
The frequency converter can be controlled by
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.
AC Brake was selected in 2-10 Brake Function.
The AC brake over-magnetizes the motor to
achieve a controlled slow down.
Automatic motor adaptation (AMA) was
carried out successfully.
AMA is ready to start. Press [Hand On] to start.
AMA process is in progress.
The brake chopper is in operation. Generative
energy is absorbed by the brake resistor.
The brake chopper is in operation. The power
limit for the brake resistor defined in
