1792-
2047
The DSP has reported a communication fault.
2064-
2079
An installed option has illegally restarted.
2080-
2127
An installed option did not initialize within the allowed
time period.
2304-
2559
The is a communication problem with the power card or
the power card configuration is invalid. Some possible
values and reasons are listed below.
2314: Could not read any data from the power card
EEPROM.
2315: Could not read software version from the power card.
2316: Did not receive initial communication from the
power card.
2324: Power card configuration is determined to the
incorrect at power up.
2330: Power size information between the power cards
does not match.
2333: Unsupported power card installed.
2335: Unsupported power size.
2336: The power card has stopped communicating.
2560-
2815
A communication problem has been encountered with the
DSP.
2816-
3071
An internal system error has occured.
3072-
5119
Parameter value outside its limits. Perform an initialization.
Subtract 3072 from the report value to obtain the
parameter number causing the alarm. For example: Error
code 3238: 3238-3072=166 is outside the limit.
NOTE
ALARM 21 replaces this report value range.
5120-
5375
An installed option is not compatible with the control card.
5376-
5631
The control card has a encountered an internal memory
error.
5632
+
The control card has encountered an internal error.
ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not available on
the power card. The problem could be on the power card, on
the gate drive card, or the ribbon cable between the power
card and gate drive card.
WARNING 40, Overload of Digital Output Terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection. Check 5-00 Digital I/O Mode and
5-01 Terminal 27 Mode.
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.
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: 24V, 5V, +/-
18V. When powered with 24V DC with the MCB 107 option,
only the 24V and 5V supplies are monitored. When powered
with three phase mains voltage, all three supplied are
monitored.
WARNING 47, 24V supply low:
The external 24 V DC backup power supply may be
overloaded, otherwise Contact your Danfoss supplier.
WARNING 48, 1.8V supply low:
Contact your Danfoss supplier.
WARNING 59, Current limit:
The required current for regulating the DC bus has exceeded
the maximum rating of the AFE. The maximum rating is
given in 16-37 Inv. Max. Current
WARNING 62, Output Frequency at Maximum Limit:
The output frequency has exeeded the specified deviation
limit relative to the programmed mains frequency. The
ALARM/WARNING is generated after exceeding the limit for
the programmed timeout period.
WARNING 64, Voltage Limit:
A warning i generated, when the AFE controller saturates.
This indicated that the AFE no longer has enough voltage
overhead for the real and reactive current control.
An alarm is generated , when the PWM controller has
exceeded 98% duty cycle.
WARNING/ALARM/TRIP 65, Control Card Over Temperature:
Control card over temperature: The cut-out temperature of
the control card is 80°C.
WARNING 66, Heatsink Temperature Low:
The heat sink temperature is measured as 0°C. This could
indicate that the temperature sensor is defect and thus the
fan speed is increased to the maximum in case the power
unit or control card is very hot.
ALARM 67, Option Configuration has Changed:
One or more options has either been added or removed
since the last power down.
ALARM 68, Safe Stop:
Safe Stop has been activated. To resume normal operation,
apply 24V DC to T-37. Press reset button on LCP.
ALARM 70, Illegal FC Configuration:
Actual combination of control board and power board is
illegal.
WARNING 73, Safe stop auto restart
Safe stopped. Note that with automatic restart enabled, the
AFE may start when the fault is cleared.
WARNING 77, Reduced power mode:
This warning indicates that the AFE is operating in reduced
power number of power units (Emergency Mode). All
functionality is active, but reduced current limits are
imposed.
