smoothly, poor duty point, distorted installation).
Check vibration limit values in the Digital Data In-
terface and correct if necessary.
2005
B FC Overload Alarm Temperature sensor of the perform-
ance card records excessive or in-
sufficient temperature. Check frequency converter ventilation.
2005
B FC Overload Alarm Switch-off temperature (75 °C) of
the control card reached. Check frequency converter ventilation.
2005
B FC Overload Alarm Inverter overload Compare rated current:
- Compare output current displayed at LCP with
rated current of the frequency converter
- Compare the output current displayed at the LCP
with measured motor current
Display thermal load on LCP and monitor value:
- If the frequency converter is operated
above the
permanent rated current, the counter increases.
- If the frequency converter is operated
below the
permanent rated current, the counter decreases.
