After a short circuit alarm (I
(I ), or imbalance of supply voltage, this contains the
max1
power card number associated with the alarm. It only
holds 1 number indicating the highest priority power card
number (master first). The value persists on power cycle,
but if a new alarm occurs it is overwritten by the new
power card number (even if it is a lower priority number).
The value is only cleared when the alarm log is cleared
(that is a 3-finger reset would reset the readout to 0).

Function:
[0 - 10000 A] Shows the motor phase V
current. Facilitates monitoring of
imbalance in the motor currents,
detection of weak motor cables or
imbalance in motor windings.
Function:
[0 - 10000 A] Shows the motor phase W
current. Facilitates monitoring of
imbalance in the motor currents,
detection of weak motor cables or
imbalance in motor windings.
Function:
[0 - 8 ] The value indicates source of
current fault, including:
•
Short circuit.
•
Overcurrent.
•
Imbalance of supply
voltage (from left): 1–4 –
inverter, 5–8 – rectifier, 0 –
no fault recorded.
