The brake chopper is in operation. Generative energy is
absorbed by the brake resistor.
Braking max.
The brake chopper is in operation. The power limit for the
brake resistor defined in
2-12 Brake Power Limit (kW)
is
reached.
Bus Jog 1
PROFIDrive profile
was selected in
8-10 Control Word Profile
.
The Jog 1 function is activated via serial communication.
The motor is running with
8-90 Bus Jog 1 Speed
.
Bus Jog 2
PROFIDrive profile
was selected in
8-10 Control Word Profile
.
The Jog 2 function is activated via serial communication.
The motor is running with
8-91 Bus Jog 2 Speed
.
Catch up
The output frequency is corrected by the value set in
3-12 Catch up/slow Down Value
.
1.
Catch up is selected as a function for a digital
input (parameter group 5-1*). The corresponding
terminal is active.
2.
Catch up was activated via serial communication.
Coast
1.
Coast inverse has been selected as a function for
a digital input (parameter group 5-1*). The
corresponding terminal (e.g. Terminal 27) is not
connected.
2.
Coast is on 0 on serial communication.
Control ready
PROFIDrive profile
was selected in
8-10 Control Word Profile
.
The FC needs the second part (e.g. 0x047F) of the two-part
start command via serial communication to allow starting.
Using a terminal is not possible.
Ctrl. Ramp-down
A function with Ctrl. Ramp-down was selected in
14-10 Mains Failure
. The Mains Voltage is below the value
set in
14-11 Mains Voltage at Mains Fault
. The FC ramps
down the motor using a controlled ramp down.
Current High
In
4-51 Warning Current High
, a current limit is set. The
output current of the FC is above this limit.
Current Low
In
4-50 Warning Current Low
, a current limit is set. The
output current of the FC is below this limit.
DC Hold
The motor is driven with a permanent DC current,
2-00 DC
Hold Current
. DC hold is selected in
1-80 Function at Stop
. A
Stop command (e.g. Stop (inverse)) is active.
DC Stop
The motor is momentarily driven with a DC current,
2-01 DC Brake Current
, for a specified time,
2-02 DC Braking
Time
.
1.
DC Brake is activated (OFF) in
2-03 DC Brake Cut
In Speed [RPM]
and a Stop command (e.g. Stop
(inverse)) is active.
2.
DC Brake (inverse) is selected as a function for a
digital input (parameter group 5-1*). The
corresponding terminal is not active.
3.
The DC Brake is activated via serial communi-
cation.
DC Voltage U0
In
1-01 Motor Control Principle
U/f and in
1-80 Function at
Stop
DC Voltage U0 is selected. A Stop command (e.g.
Stop (inverse)) is activated. The voltage selected according
to the
1-55 U/f Characteristic - U
[0] (UF Characteristic –
U[V]) is applied to the motor.
Feedback high
In
4-57 Warning Feedback High
, an upper feedback limit is
set. The sum of all active feedbacks is above the feedback
limit.
Feedback low
In
4-56 Warning Feedback Low
, a lower feedback limit is set.
The sum of all active feedbacks is below the feedback
limit.
Flying start
In
1-73 Flying Start
, the Flying start function is activated.
The FC 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*) programmed as Coast inverse or by connecting to
mains.
Freeze output
The remote reference is active and the momentarily given
speed is saved.
1.
Freeze output was selected as a function for a
digital input (Group 5-1*). The corresponding
terminal is active. Speed control is only possible
via the terminal functions Speed up and Speed
down.
2.
Hold ramp is activated via serial communication.
Freeze output request
A freeze output command has been given, but the motor
will remain stopped until a
Run permissive
signal is received
via a digital input.
Freeze Ref.
Freeze Ref. was chosen as a function for a digital input
(parameter group 5-1*). The corresponding terminal is
controlled. The FC 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.
