VLT Decentral Drive FCD 302 Operating Instructions
Operation Status
Protection mode is active. The unit has detected
a critical status (an overcurrent or overvoltage).
•
To avoid tripping, switching frequency is
reduced to 4kHz.
•
If possible, protection mode ends after
approximately 10sec.
•
Protection mode can be restricted in
14-26 Trip Delay at Inverter Fault
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.
The motor is accelerating/decelerating using
the active Ramp Up/Down. The reference, a
limit value or a standstill is not yet reached.
The sum of all active references is above the
reference limit set in 4-55 Warning Reference
High.
The sum of all active references is below the
reference limit set in 4-54 Warning Reference
Low .
The frequency converter is running in the
reference range. The feedback value matches
the setpoint value.
A start command has been given, but the motor
is stopped until a run permissive signal is
received via digital input.
The motor is driven by the frequency converter.
The energy saving function is enabled. This
means that at present the motor has stopped,
but that it will restart automatically when
required.
Motor speed is above the value set in
4-53 Warning Speed High.
Motor speed is below the value set in
4-52 Warning Speed Low.
In Auto On mode, the frequency converter will
start the motor with a start signal from a digital
input or serial communication.
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 forward and start reverse were selected as
functions for two different digital inputs
(parameter group 5-1*). The motor will start in
forward or reverse depending on which
corresponding terminal is activated.
The frequency converter has received a stop
command from the LCP, digital input or serial
communication.

Operation Status
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.
