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 profile was selected in
parameter 8-10 Control Profile
. The drive needs
the first 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
specified 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.
