Jogging
The motor is running 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 is active.
•
The jog function is activated via the serial
communication.
•
The jog function was selected as a reaction
for a monitoring function. The monitoring
function is active.
Motor check
In
parameter 1-80 Function at Stop
,
Motor
Check
was selected. A stop command is active.
To ensure that a motor is connected to the
frequency converter, a permanent test current
is applied to the motor.
OVC Control
Overvoltage
control was activated in
parameter 2-17 Over-voltage Control
,
[2]
Enabled
. The connected motor supplies the
frequency converter with generative energy.
The overvoltage control adjusts the V/Hz ratio
to run the motor in controlled mode and to
prevent the frequency converter from tripping.
Power Unit Off
(Only frequency converters with a 24 V
external supply installed).
Mains supply to the frequency converter 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, the switching frequency
is reduced to 4 kHz.
•
If possible, protection mode ends after
approximately 10 s.
•
Protection mode can be restricted in
parameter 14-26 Trip Delay at Inverter Fault
.
QStop
The motor is decelerating using
parameter 3-81 Quick Stop Ramp Time
.
•
Quick stop inverse
was selected as a
function for a digital input (
parameter
group 5-1* Digital Inputs
). The
corresponding terminal is not active.
•
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
The sum of all active references is above the
reference limit set in
parameter 4-55 Warning
Reference High
.
Ref. low
The sum of all active references is below the
reference limit set in
parameter 4-54 Warning
Reference Low
.
Run on ref.
The frequency converter is running in the
reference range. The feedback value matches
the setpoint value.
Run request
A start command has been given, but the
motor is stopped until a run permissive signal
is received via digital input.
Running
The frequency converter drives the motor.
Sleep Mode
The energy saving function is enabled. The
motor has stopped, but restarts automatically
when required.
Speed high
Motor speed is above the value set in
parameter 4-53 Warning Speed High
.
Speed low
Motor speed is below the value set in
parameter 4-52 Warning Speed Low
.
Standby
In Auto On mode, the frequency converter
starts the motor with a start signal from a
digital input or serial communication.
Start delay
In
parameter 1-71 Start Delay
, a delay starting
time was set. A start command is activated
and the motor starts after the start delay time
expires.
Start fwd/rev
Start forward and start reverse were selected
as functions for 2 different digital inputs
(
parameter group 5-1* Digital Inputs
). The
motor starts in forward or reverse depending
on which corresponding terminal is activated.
Stop
The frequency converter has received a stop
command from the LCP, digital input, or serial
communication.
Trip
An alarm occurred and the motor is stopped.
Once the cause of the alarm is cleared, the
frequency converter can be reset manually by
pressing [Reset] or remotely by control
terminals or serial communication.
Trip lock
An alarm occurred and the motor is stopped.
Once the cause of the alarm is cleared, power
must be cycled to the frequency converter.
The frequency converter can then be reset
manually by pressing [Reset] or remotely by
control terminals or serial communication.
Table 6.4 Operation Status
NOTICE
In auto/remote mode, the frequency converter requires
external commands to execute functions.
