Danfoss vlt fcd 302 User Manual

Operation Status
Motor check
In 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 2-17 Over-
voltage Control. The connected motor is
supplying 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.
PowerUnit Off (For frequency converters with an external 24
V power supply installed
only.) 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, switching frequency is
reduced to 4 kHz.
•
If possible, protection mode ends after
approximately 10 s
•
Protection mode can be restricted in
14-26 Trip Delay at Inverter Fault
QStop
The motor is decelerating using 3-81 Quick
Stop Ramp Time
.
•
Quick stop inverse was chosen as a function
for a digital input (parameter group 5-1*).
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
4-55 Warning Reference
High.
Ref. low The sum of all active references is below the
reference limit set in
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 runs the motor.
Sleep Mode The energy saving function is enabled. The
motor
has stopped, but
will restart automat-
ically when required.
Operation Status
Speed high Motor speed is above the value set in
4-53
Warning Speed High
.
Speed low Motor speed is below the value set in
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 1-71 Start Delay, a delay starting time was
set. A start
command is activated and the
motor will start after the start delay time
expires.
Start fwd/rev Start forward and start reverse were selected
as functions for two
different digital inputs
(parameter group 5-1*). 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.
