vacon operation and programming
5
Table 5 shows Vacon 500x keypad warning messages that may appear during operation:
FWD At Spd
The drive is spinning the motor in the forward direction and the speed of the
motor is at the reference frequency.
REV At Spd
The drive is spinning the motor in the reverse direction and the speed of the
motor is at the reference frequency.
Zero Speed
The drive has an active run signal but the motor is not spinning because the
reference speed to the drive must be 0.0 Hz.
DC Inject
The drive is injecting DC voltage into the motor.
Faulted
The drive is faulted.
Reset-Flt
The drive is faulted, but has the possibility of being automatically reset.
LS Lockout
Line-Start Lockout functionality has become active. This means there was an
active run signal during power-up or when a fault was reset. This run signal
must be removed before the Line-Start Lockout functionality will be removed.
Catch Fly
The Catch on the Fly functionality is actively searching for the motor frequency.
Forward
The drive is running forward without accelerating, decelerating or residing at
the reference frequency. This means that something is keeping the drive from
the reference frequency (for example, Current Limit).
Reverse
The drive is running in reverse without accelerating, decelerating or residing at
the reference frequency. This means that something is keeping the drive from
the reference frequency (for example, Current Limit).
Not Enabled
The drive is not allowed to run either because the digital input enable is not
active or because ARCTIC mode has shut down the run operation.
Volt Range
The drive has not met the input voltage voltage requirements that it needs to be
able to run. In other words, the Bus Voltage of the drive is either too low or too
high.
Low Voltage
The drive has reached an undervoltage state.
Kpd Stop
A stop command was given from the keypad when the keypad was not the active
control source. To remove this condition, the run signal to the drive must be
removed.
TOD Inhibit
The drive is not enabled because of time restrictions programmed into the Time
of Day parameters.
Message
Meaning
DB Active
The DB Resistor is being actively pulsed.
Curr Limit
The drive is operating in current limit.
HS Fan Err
Either the heatsink fan should be on and is off, or vice-versa.
Addr XXX
This is the node address of the drive when it receives a valid message through the IR
port address to another node. The XXX will be replaced with the node address.
High Temp
The temperature of either the heatsink or the control board is nearing a high
temperature limit that will fault the drive.
Low Temp
The temperature of either the heatsink or the control board is nearing a low
temperature limit that will fault the drive.
Vac Imblnce
Either the drive has lost an input phase or the input voltage is unbalanced more than
2%.
Power Supp
A power supply short occurred.
Seq Dwell
The sequencer is active, but the transition to the next step is halted.
Int Fan Err
Either the internal fan is on and should be off, or vice-versa.
DB OverTemp
The temperature of the DB Resistor is nearing a high temperature and will fault the
drive.
ARCTIC Mode
The ARCTIC DB Resistor mode is actively pulsing the DB Resistor.
