Operation Status
failure.
•
The AC line voltage is below the value set
in SP-11 Line Voltage at Input 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 H-71 Warning Current
High.
The adjustable frequency drive output current
is below the limit set in H-70 Warning Current
Low
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.
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. The corresponding
terminal is not active.
•
The DC Brake is activated via serial
communication.
The sum of all active feedback is above the
feedback limit set in H-77 Warning Feedback
High.
The sum of all active feedback is below the
feedback limit set in H-76 Warning Feedback
Low.
The remote reference is active, which holds
the present speed.
•
Freeze output was selected as a function
for a digital input. The corresponding
terminal is active. Speed control is only
possible via the terminal functions Speed
Up and Slow.
•
Hold ramp is activated via serial communi-
cation.
A freeze output command has been given,
but until a run permissive signal is received,
the motor remains stopped.
Freeze ref.
Freeze Reference was chosen as a function for
a digital input. The corresponding terminal is
active. The adjustable frequency drive saves
the actual reference. Changing the reference is
now only possible via terminal functions
Speed Up and Slow.
Jog request
A jog command has been given, but until a
run permissive signal is received via a digital
input, the motor is stopped
Jogging
The motor is running as programmed in
C-21 Jog Speed [RPM].
•
Jog was selected as function for a digital
input. The corresponding terminal (for
example, 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 (for
example, No signal). The monitoring
function is active.
Over Voltage
Overvoltage control was activated in B-17 Over-
Control (OVC)
voltage Control. The connected motor is
supplying the adjustable frequency drive with
generative energy. The overvoltage control
adjusts the V/Hz ratio to run the motor in
controlled mode and to prevent the
adjustable frequency drive from tripping.
PowerUnit Off
(For adjustable frequency drives with an
external 24 V power supply installed only.)
Line power supply to the adjustable frequency
drive is removed, but the control card is
supplied by the external 24 V.
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 4 kHz.
•
If possible, Protection mode ends after
approximately 10 s
•
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. The corresponding
terminal is not active.
•
The quick stop function was activated via
serial communication.
