Danfoss VLT AQUA Drive FC 202 Operating Manual

WARNING
HIGH VOLTAGE
Drives contain high voltage when connected to AC mains
input, DC supply, or load sharing. Failure to perform
installation, start-up, and maintenance by qualied
personnel can result in death or serious injury.
•
Only qualied personnel must perform instal-
lation, start-up, and maintenance.
•
Before performing any service or repair work,
use an appropriate voltage measuring device to
make sure that there is no remaining voltage on
the drive.
Troubleshooting
•
Remove the power from the drive and check
motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time
period.
Troubleshooting
•
Let the unit cool to operating temperature.
•
Check potential DC-link fault to ground.
WARNING/ALARM 34, Fieldbus communication fault
The
eldbus on the communication option card is not
working.
WARNING/ALARM 35, Option fault
An option alarm is received. The alarm is option-specic.
The most likely cause is a power-up or a communication
fault.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the drive system is lost and parameter 14-10 Mains Failure
is not set to option [0] No Function.
•
Check the fuses to the drive system and the
mains supply to the unit.
•
Check that mains voltage conforms to product
specications.
•
Check that the following conditions are not
present:
Alarm 307, Excessive THD(V), alarm 321, Voltage
imbalance, warning 417, Mains undervoltage, or
warning 418, Mains overvoltage is reported if any
of the listed conditions are true:
- The 3-phase voltage magnitude drops
below 25% of the nominal mains
voltage.
- Any single-phase voltage exceeds 10%
of the nominal mains voltage.
- Percent of phase or magnitude
imbalance exceeds 8%.
- Voltage THD exceeds 10%.
ALARM 37, Phase imbalance
There is a current imbalance between the power units.
ALARM 38, Internal fault
When an internal fault occurs, a code number dened in
Table 9.4 is shown.
Troubleshooting
•
Cycle power.
•
Check that the option is properly installed.
•
Check for loose or missing wiring.
It may be necessary to contact the Danfoss supplier or
service department. Note the code number for further
troubleshooting directions.
Number Text
0 The serial port cannot be initialized. Contact the
Danfoss supplier or Danfoss service department.
256–258 The power EEPROM data is defective or too old.
Replace the power card.
512–519 Internal fault. Contact the Danfoss supplier or
Danfoss service department.
783 Parameter value outside of minimum/maximum
limits.
1024–1284 Internal fault. Contact the Danfoss supplier or
Danfoss service department.
1299 The option software in slot A is too old.
1300 The option software in slot B is too old.
1302 The option software in slot C1 is too old.
1315 The option software in slot A is not supported/
allowed.
1316 The option software in slot B is not supported/
allowed.
1318 The option software in slot C1 is not supported/
allowed.
1379–2819 Internal fault. Contact the Danfoss supplier or
Danfoss service department.
1792 Hardware reset of digital signal processor.
1793 Motor-derived parameters not transferred correctly
to the digital signal processor.
1794 Power data not transferred correctly at power-up
to the digital signal processor.
1795 The digital signal processor has received too many
unknown SPI telegrams. The AC drive also uses
this fault code if the MCO does not power up
correctly. This situation can occur due to poor EMC
protection or improper grounding.
1796 RAM copy error.
2561 Replace the control card.
2820 LCP stack overow.
2821 Serial port overow.
2822 USB port overow.
3072–5122 Parameter value is outside its limits.
