Danfoss vlt FC 102 Programming Guide

16-46 Motor Phase V Current
Range: Function:
0 A* [0 - 10000 A] Shows the motor phase V
RMS
current. Facilitates monitoring of
imbalance in the motor currents,
detection of weak motor cables or
imbalance in motor windings.
16-47 Motor Phase W Current
Range: Function:
0 A* [0 - 10000 A] Shows the motor phase W
RMS
current. Facilitates monitoring of
imbalance in the motor currents,
detection of weak motor cables or
imbalance in motor windings.
16-49 Current Fault Source
Range: Function:
0* [0 - 8 ] The value indicates source of
current fault, including:
•
Short circuit.
•
Overcurrent.
•
Imbalance of supply
voltage (from left): 1–4 –
inverter, 5–8 – rectier, 0 –
no fault recorded.
After a short circuit alarm (I
max2
), or overcurrent alarm
(I
max1
), or imbalance of supply voltage, this contains the
power card number associated with the alarm. It only
holds 1 number indicating the highest priority power card
number (master rst). 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-nger reset would reset the readout to 0).
3.16.4 16-5* Ref. & Feedb.
16-50 External Reference
Range: Function:
0* [-200 - 200 ] View the total reference, the sum of
digital, analog, preset, eldbus, and
freeze references, plus catch up and
slow down.
