LED’s
Power LED:
The power LED indicates that there is AC power applied to the drive
and that the logic supply is active.
Over Current LED:

circuit from phase to ground or phase to phase. It may also be caused
by a non-compatible motor being used.
Over temperature LED:
This LED shows that the unit has shut down due to an over
temperature situation, which could be caused by the temperature of
the heat sink being in excess of 70
°
C (158
°
F) or the ambient
temperature is greater than 50
°
C (122
°
F).
Regen on LED:
When this LED is on the regenerative circuitry is active. It does not
indicate a fault.
Over Current LED
If the over current and the over temperature LED’s are active
&
this indicates that an over voltage condition has occurred, bus
Over temperature LED:
voltage > 410VDC.
