Table 7.5 Internal Fault, Code Numbers
ALARM 39, Heat sink sensor
No feedback from the heat sink 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 the
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 the
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
the 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
the short-circuit connection. Check 5-33 Term X30/7 Digi
Out (MCB 101).
ALARM 45, Earth fault 2
Ground fault.

ALARM 46, Power card supply
The supply on the power card is out of range.
There are 3 power supplies generated by the switch mode
power supply (SMPS) on the power card: 24 V, 5 V, and±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 3-phase mains voltage, all 3 supplies are
monitored.
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. This alarm
appears when the detected voltage of terminal 12 is <18
V.

Check for proper grounding and loose
connections.
Check for proper wire size.
Check the motor cables for short circuits or
leakage currents.
Check for a defective control card.
