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 is controlled by the navigation keys on the LCP. Stop
commands, reset, reversing, DC brake, and other signals applied to the control
terminals 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.
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 2-12 Brake Power Limit (kW) has been reached.
• Coast inverse was selected as a function for a digital input (parameter group
5-1* Digital Inputs). The corresponding terminal is not connected.
• Coast activated by serial communication
Control Ramp-down was selected in 14-10 Mains Failure.
• The AC line voltage is below the value set in 14-11 Mains Voltage at Mains
Fault at line power fault
• The adjustable frequency drive ramps down the motor using a controlled
ramp-down.
The adjustable frequency drive output current is above the limit set in 4-51
Warning Current High.
The adjustable frequency drive output current is below the limit set in 4-52
Warning Speed Low.
DC Hold is selected in 1-80 Function at Stop and a stop command is active. The
motor is held by a DC current set in 2-00 DC Hold/Preheat Current.
The motor is held with a DC current (2-01 DC Brake Current) for a specified time
(2-02 DC Braking Time).
• DC Brake is activated in 2-03 DC Brake Cut In Speed [RPM] and a stop
command is active.
• DC Brake (inverse) is selected as a function for a digital input (parameter
group 5-1* Digital Inputs). The corresponding terminal is not active.
• The DC Brake is activated via serial communication.
The sum of all active feedbacks is above the feedback limit set in 4-57 Warning
Feedback High.
The sum of all active feedbacks is below the feedback limit set in 4-56 Warning
Feedback Low.
