The adjustable frequency drive does not react
to any control signal until [Auto On] or [Hand
On] is pressed.
The adjustable frequency drive is controlled
from the control terminals and/or the serial
communication.
The adjustable frequency drive 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 adjustable frequency drive uses [Hand On]
control or reference values from the LCP.

AC Brake was selected in 2-10 Brake Function.
The AC brake overmagnetizes 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.
