Catch up The value set in parameter 3-12 Catch up/slow
Down Value corrects the output frequency.
•
Catch up is selected as a function for a
digital input (parameter group 5-1* Digital
Inputs). The corresponding terminal is
active.
•
Catch up was activated via serial communi-
cation.
Coast
•
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 ready PROFIdrive prole was selected in
parameter 8-10 Control Prole. The drive needs
the rst part (for example, 0x047E) of the 2-
part start command via serial communication
to allow starting. Using a terminal is not
possible.
Ctrl. ramp-down [1] Ctrl. ramp-down was selected in
parameter 14-10 Mains Failure.
•
The mains voltage is below the value set
in parameter 14-11 Mains Fault Voltage Level
at mains fault.
•
The drive ramps down the motor using a
controlled ramp down.
Current high The drive output current is above the limit set
in parameter 4-51 Warning Current High.
Current low The drive output current is below the limit set
in parameter 4-50 Warning Current Low.
DC hold [1] DC hold is selected in
parameter 1-80 Function at Stop and a stop
command is active. The motor is held by a DC
current set in parameter 2-00 DC Hold/Preheat
Current.
DC stop The motor is held with a DC current
(parameter 2-01 DC Brake Current) for a
specied time (parameter 2-02 DC Braking
Time).
•
DC brake is activated in parameter 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.
DC voltage U0 In parameter 1-01 Motor Control Principle and
in parameter 1-80 Function at Stop, [4] DC
Voltage U0 is selected. When a stop command
(for example, Stop (inverse)) is activated, the
voltage selected according to the
parameter 1-55 V/f Characteristic - V is applied
to the motor.
Feedback high The sum of all active feedbacks is above the
feedback limit set in parameter 4-57 Warning
Feedback High.
Feedback low The sum of all active feedbacks is below the
feedback limit set in parameter 4-56 Warning
Feedback Low.
Flying start The drive is testing if the connected motor is
running with a speed that is in the adjusted
speed range. The process was started by
connecting a digital input (parameter group
5-1* Digital Inputs) programmed as coast
inverse or by connecting to the mains.
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 5-1*
Digital Inputs). The corresponding terminal
is active. Speed control is possible only via
the terminal functions speed up and speed
down.
•
Hold ramp is activated via serial communi-
cation.
Freeze output
request
A freeze output command has been given, but
the motor remains stopped until a run
permissive signal is received.
Freeze ref. Freeze reference was selected as a function for
a digital input (parameter group 5-1* Digital
Inputs). The corresponding terminal is active.
The drive 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 is stopped until a run permissive signal
is received via a digital input.
Jogging The motor runs as programmed in
parameter 3-19 Jog Speed [RPM].
•
Jog was selected as function for a digital
input (parameter group 5-1* Digital Inputs).
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.
