Danfoss VLT AutomationDrive FC 300 User Manual

Troubleshooting:
Check the operation of the door fans.
Check that the filters for the door fans are not
blocked.
Check that the gland plate is properly installed
on IP 21 and IP 54 (NEMA 1 and NEMA 12)
frequency converters.
ALARM 70, Illegal FC Configuration
Actual combination of control board and power board is
illegal.
WARNING/ALARM 71, PTC 1 safe stop
Safe Stop has been activated from the MCB 112 PTC
Thermistor Card (motor too warm). Normal operation can
be resumed when the MCB 112 applies 24 V DC to T-37
again (when the motor temperature reaches an acceptable
level) and when the Digital Input from the MCB 112 is
deactivated. When that happens, a reset signal must be is
be sent (via serial communication, digital I/O, or by
pressing [Reset] on the LCP). Note that if automatic restart
is enabled, the motor may start when the fault is cleared.
ALARM 72, Dangerous failure
Safe stop with trip lock. Unexpected signal levels on safe
stop and digital input from the MCB 112 PTC thermistor
card.
WARNING/ALARM 73, Safe stop auto restart
Safe stopped. Note that with automatic restart enabled,
the motor may start when the fault is cleared.
WARNING 76, Power Unit Setup
The required number of power units does not match the
detected number of active power units.
Troubleshooting:
When replacing an F frame module this will occur if the
power specific data in the module power card does not
match the rest of the frequency converter. Confirm the
spare part and its power card are the correct part number.
WARNING 77, Reduced power mode:
This warning indicates that the frequency converter is
operating in reduced power mode (i.e. less than the
allowed number of inverter sections). This warning will be
generated on power cycle when the frequency converter is
set to run with fewer inverters and will remain on.
ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not
installed. Also MK102 connector on the power card could
not be installed.
ALARM 80, Drive initialized to default value
Parameter settings are initialized to default settings after a
manual reset.
WARNING 81, CSIV corrupt:
CSIV file has syntax errors.
WARNING 82, CSIV parameter error:
CSIV parameter error.
WARNING 85, Dang fail PB:
Profibus/Profisafe Error.
ALARM 91, Analog input 54 wrong settings
Switch S202 has to be set in position OFF (voltage input)
when a KTY sensor is connected to analog input terminal
54.
ALARM 243, Brake IGBT
This alarm is only for F Frame sizes. It is equivalent to
Alarm 27. The report value in the alarm log indicates
which power module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in frame sizes F2 or
F4.
2 = right inverter module in frame sizes F1 or F3 .
3 = right inverter module in frame sizes F2 or F4 .
5 = rectifier module.
ALARM 244, Heatsink temperature
This alarm is only for F Frame. It is equivalent to Alarm 29.
The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in frame sizes F2 or
F4.
2 = right inverter module in frame sizes F1 or F3.
3 = right inverter module in frame sizes F2 or F4.
5 = rectifier module.
ALARM 245, Heatsink sensor
This alarm is only for F Frame. It is equivalent to Alarm 39.
The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in frame sizes F2 or
F4.
2 = right inverter module in frame sizes F1 or F3.
3 = right inverter module in frame sizes F2 or F4.
5 = rectifier module.
ALARM 246, Power card supply
This alarm is only for F Frame. It is equivalent to Alarm 46.
The report value in the alarm log indicates which power
module generated the alarm:
1 = left most inverter module.
2 = middle inverter module in frame sizes F2 or
F4.
2 = right inverter module in frame sizes F1 or F3.
3 = right inverter module in frame sizes F2 or F4.
5 = rectifier module.
