Table 7.1 Internal Fault, Code Numbers
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 the
short-circuit connection. Check parameter 5-00 Digital I/O
Mode and parameter 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 parameter 5-00 Digital I/O
Mode and parameter 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 parameter 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 parameter 5-33 Term
X30/7 Digi Out (MCB 101).
ALARM 45, Ground fault 2
Ground fault.

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: 24 V, 5 V,
±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 three phase AC line voltage, all three
supplies are monitored.

Option in slot B: Hardware incompatible with
control board hardware.
Option in slot C0: Hardware incompatible with
control board hardware.
Option in slot C1: Hardware incompatible with
control board hardware.
Check for proper grounding and loose
connections.
Check for proper wire size.
Check the motor cables for short circuits or
leakage currents.
