The motor is running with
3-19 Jog Speed [RPM]
.
1.
Jog was selected as function for a digital input
(parameter group 5-1*). The corresponding
terminal (e.g. Terminal 29) is active.
2.
The Jog function is activated via the serial
communication.
3.
The Jog function was selected as a reaction for a
monitoring function (e.g. No signal). The
monitoring function is active.
Kinetic backup
In
14-10 Mains Failure
, a function was set as kinetic backup.
The Mains Voltage is below the value set in
14-11 Mains
Voltage at Mains Fault
. The FC is running the motor
momentarily with kinetic energy from the inertia of the
load.
Motor check (FC 100/200 only)
In
1-80 Function at Stop
, the function Motor check was
selected. A stop command (e.g. Stop inverse) is active. To
ensure that a motor is connected to the FC, a permanent
test current is applied to the motor.
Off1
PROFIDrive profile
was selected in
8-10 Control Word Profile
.
The OFF 1 function is activated via serial communication.
The motor is stopped via the ramp.
Off2
PROFIDrive profile
was selected in
8-10 Control Word Profile
.
The OFF 2 function is activated via serial communication.
The output of the FC is disabled immediately and the
motor coasted.
Off3
PROFIDrive profile
was selected in
8-10 Control Word Profile
.
The OFF 3 function is activated via serial communication.
The motor is stopped via the ramp.
OVC control
Overvoltage Control is activated in
2-17 Over-voltage
Control
. The connected motor is supplying the FC with
generative energy. The Overvoltage Control adjusts the UF
ratio to run the motor in controlled mode and to prevent
the FC from tripping.
PowerUnit Off
Only with frequency converters with installed option (ext.
24 V supply). The mains supply to the frequency converter
is cut off, but the control card is still supplied with 24 V.
Pre-magnetize
Pre-magnetization is selected in
1-80 Function at Stop
. A
stop command (e.g. Stop inverse) is activated. A suitable
constant magnetizing current is applied to the motor.
Protection md
The FC 100/200/300 has detected a critical status (e.g. an
overcurrent, overvoltage). To avoid tripping the frequency
converter (alarm), protection mode is activated, which
includes reducing the switching frequency to 4 kHz. If
possible, protection mode ends after approximately 10 s.
Activation of protection mode can be restricted by
adjusting the
14-26 Trip Delay at Inverter Fault
.
QStop
The motor is stopped using a quick stop ramp
3-81 Quick
Stop Ramp Time
.
1.
Quick stop inverse was chosen as a function for a
digital input (parameter group 5-1*). The
corresponding terminal (e.g. Terminal 27) is not
active.
2.
The Quick stop function was activated via serial
communication.
Ramping
The motor is accelerating/decelerating using the active
Ramp Up/Down. The reference, a limit value or a standstill
is not yet reached.
Ref. high
In
4-55 Warning Reference High
a reference high limit is set.
The sum of all active references is above the reference
limit.
Ref. low
In
4-54 Warning Reference Low
a reference low limit is set.
The sum of all active references is below the reference
limit.
Run on ref.
The FC is running in the reference range. The feedback
value matches the set reference value.
Run request (FC 100/200 only)
A start command has been given, but the motor will be
stopped until a
Run permissive
signal is received via digital
input.
Running
The motor is driven by the FC, the ramping phase is done
and the motor revolutions are outside the
On Reference
range. Occurs when one of the motor speed limits (Par.
4-11/4-12/4-13 or 4-14) is set, but the maximum reference
is outside this range.
Sleep Boost (FC 100/200 only)
The boost function in
22-45 Setpoint Boost
is enabled. This
function is only possible in
Closed loop
operation.
Sleep Mode (FC 100/200)
The energy saving function in parameter 403
Sleep mode
timer
is enabled. This means that at present the motor has
stopped, but that it will restart automatically when
required.
Speed down
The output frequency is corrected by the value set in
3-12 Catch up/slow Down Value
.
1.
Speed down was selected as a function for a
digital input (parameter group 5-1*). The
corresponding terminal is active.
2.
Speed down was activated via serial communi-
cation.
