Danfoss VLT AutomationDrive FC 300 User Manual

WARNING 41, Overload of Digital Output Terminal 29
Check the load connected to terminal 29 or remove short-
circuit connection. Check 5-00 Digital I/O Mode and
5-02 Terminal 29 Mode.
WARNING 42, Overload of Digital Output on X30/6 or
Overload of Digital Output on X30/7
For X30/6, check the load connected to X30/6 or remove
short-circuit connection. Check 5-32 Term X30/6 Digi Out
(MCB 101).
For X30/7, check the load connected to X30/7 or remove
short-circuit connection. Check 5-33 Term X30/7 Digi Out
(MCB 101).
ALARM 46, Power card supply
The supply on the power card is out of range.
There are three power supplies generated by the switch
mode power supply (SMPS) on the power card: 24 V, 5 V,
±18 V. When powered with 24 V DC with the MCB 107
option, only the 24 V and 5 V supplies are monitored.
When powered with three phase mains voltage, all three
supplied are monitored.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. The external
24 V DC backup power supply may be overloaded,
otherwise contact your Danfoss supplier.
WARNING 48, 1.8 V supply low
The 1.8 V DC supply used on the control card is outside of
allowable limits. The power supply is measured on the
control card.
WARNING 49, Speed limit
The speed is not within the specified range in 4-11 Motor
Speed Low Limit [RPM] and 4-13 Motor Speed High Limit
[RPM].
ALARM 50, AMA calibration failed
Contact your Danfoss supplier.
ALARM 51, AMA check Unom and Inom
The setting of motor voltage, motor current, and motor
power is presumably wrong. Check the settings.
ALARM 52, AMA low Inom
The motor current is too low. Check the settings.
ALARM 53, AMA motor too big
The motor is too big for the AMA to be carried out.
ALARM 54, AMA motor too small
The motor is too small for the AMA to be carried out.
ALARM 55, AMA parameter out of range
The parameter values found from the motor are outside
acceptable range.
ALARM 56, AMA interrupted by user
The AMA has been interrupted by the user.
ALARM 57, AMA timeout
Try to start the AMA again a number of times, until the
AMA is carried out. Note that repeated runs may heat the
motor to a level where the resistance Rs and Rr are
increased. In most cases, however, this is not critical.
ALARM 58, AMA internal fault
Contact your Danfoss supplier.
WARNING 59, Current limit
The current is higher than the value in 4-18 Current Limit.
WARNING 60, External interlock
External interlock has been activated. To resume normal
operation, apply 24 V DC to the terminal programmed for
external interlock and reset the frequency converter (via
serial communication, digital I/O, or by pressing [Reset]).
WARNING 61, Tracking error
An error has been detected between calculated motor
speed and speed measurement from feedback device. The
function for Warning/Alarm/Disable is set in 4-30 Motor
Feedback Loss Function, error setting in 4-31 Motor
Feedback Speed Error, and the allowed error time in
4-32 Motor Feedback Loss Timeout. During a commissioning
procedure the function may be effective.
WARNING 62, Output frequency at maximum limit
The output frequency is higher than the value set in
4-19 Max Output Frequency
WARNING 64, Voltage limit
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM/TRIP 65, Control card over temperature
Control card over temperature: The cutout temperature of
the control card is 80° C.
WARNING 66, Heatsink temperature low
This warning is based on the temperature sensor in the
IGBT module.
Troubleshooting:
The heatsink temperature measured as 0° C could indicate
that the temperature sensor is defective causing the fan
speed to increase to the maximum. If the sensor wire
between the IGBT and the gate drive card is disconnected,
this warning would result. Also, check the IGBT thermal
sensor.
ALARM 67, Option module configuration has changed
One or more options have either been added or removed
since the last power-down.
ALARM 68, Safe stop activated
Safe stop has been activated. To resume normal operation,
apply 24 V DC to terminal 37, then send a reset signal (via
Bus, Digital I/O, or by pressing [Reset]. See 5-19 Terminal 37
Safe Stop.
ALARM 69, Power card temperature
The temperature sensor on the power card is either too
hot or too cold.
