ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor. The signal from the IGBT ther-
mal 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.
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 connec-
tion. 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 connec-
tion. Check 5-33 Term X30/7 Digi Out (MCB 101).
ALARM 45, Ground fault 2
Ground fault.
Troubleshooting
ALARM 46, Power card supply
The supply on the power card is out of range. There are three power supplies gener-
ated 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 sup-
plies are monitored. When powered with three-phase AC line voltage, all three sup-
plies are monitored.
