Status Messages
Ctrl. Ramp Control Ramp was selected in SP-10 Line
failure.
•
The mains voltage is below the value set
in SP-11 Line Voltage at Input Fault at
mains fault
•
The frequency converter ramps down the
motor using a controlled ramp
Current High The frequency converter output current is
above the limit set in H-71 Warning Current
High.
Current Low The frequency converter output current is
below the limit set in H-70 Warning Current
Low
DC Hold DC hold is selected in H-80 Function at Stop
and a stop command is active. The motor is
held by a DC current set in B-00 DC Hold
Current.
DC Stop The motor is held with a DC current (B-01 DC
Brake Current) for a specified time (B-02 DC
Braking Time).
•
DC Brake is activated in B-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 E-0#).
The corresponding terminal is not active.
•
The DC Brake is activated via serial
communication.
Feedback high The sum of all active feedbacks is above the
feedback limit set in H-77 Warning Feedback
High.
Feedback low The sum of all active feedbacks is below the
feedback limit set in H-76 Warning Feedback
Low.
Freeze output The remote reference is active which holds
the present speed.
•
Freeze output was selected as a function
for a digital input (parameter group E-0#).
The corresponding terminal is active.
Speed control is only possible via the
terminal functions speed up and speed
down.
•
Hold ramp is activated via serial communi-
cation.
Freeze output A freeze output command has been given,
request but the motor will remain stopped until a run
permissive signal is received.

Operation status Operation status
Freeze ref. Freeze Reference was chosen as a function for
a digital input (parameter group E-0#). The
corresponding terminal is active. The
frequency converter saves the actual
reference. Changing the reference is now only
possible via terminal functions speed up and
speed down.
Jog request A jog command has been given, but the
motor will be stopped until a run permissive
signal is received via a digital input.
Jogging The motor is running as programmed in
C-21 Jog Speed [RPM].
•
Jog was selected as function for a digital
input (parameter group E-0#). The
corresponding terminal (e.g. Terminal 29) is
active.
•
The Jog function is activated via the serial
communication.
•
The Jog function was selected as a
reaction for a monitoring function (e.g. No
signal). The monitoring function is active.
Motor check In H-80 Function at Stop, Motor Check was
selected. A stop command is active. To ensure
that a motor is connected to the frequency
converter, a permanent test current is applied
to the motor.
OVC control Overvoltage control was activated in B-17 Over-
voltage Control. The connected motor is
supplying the frequency converter with
generative energy. The overvoltage control
adjusts the V/Hz ratio to run the motor in
controlled mode and to prevent the frequency
converter from tripping.
PowerUnit Off (For frequency converters with an external 24V
power supply installed only.) Mains supply to
the frequency converter is removed, but the
control card is supplied by the external 24V.
Protection md Protection mode is active. The unit has
detected a critical status (an overcurrent or
overvoltage).
•
To avoid tripping, switching frequency is
reduced to 4kHz.
•
If possible, protection mode ends after
approximately 10sec.
•
Protection mode can be restricted in
SP-26 Trip Delay at Drive Fault
QStop The motor is decelerating using C-23 Quick
Stop Decel Time.
•
Quick stop inverse was chosen as a function
for a digital input (parameter group E-0#).
The corresponding terminal is not active.
•
The quick stop function was activated via
serial communication.
