Inv Overtemp Trp
VP, Flashing
red
Soft
Inverter overtemperature trip.
There is excessive temperature
at the heatsink.
When this condition occurs, the
drive coasts to a stop regardless
of the selected stop type.
Check the cabinet filters, drive fans, and heatsinks.
Check the thermal sensor and sensor wiring (connector).
Reduce the load or duty cycle if possible.
Lower the value of PWM Frequency (parameter 10).
Check the roof fan direction of rotation (H frame only).
Rotation should be counter-clockwise when viewed from
the top.

Inv Overtemp Pnd
VP, Flashing
red
Soft
An inverter overtemperature is
pending. The inverter heatsink
temperature is approaching the
trip level.
Check the cabinet filters, drive fans, and heatsinks.
Check the thermal sensor and sensor wiring (connector).
Reduce the load or duty cycle if possible.
Lower the value of PWM Frequency (parameter 10).
Check the roof fan direction of rotation (H frame only).
Rotation should be counter-clockwise when viewed from
the top.
If you do not want this condition to be reported as a fault,
change bit 1 in Fault Select 2 (parameter 22) to 0.

VP, Flashing
red
Soft
An inverter (IT) overload is
pending. The inverter current has
been in excess of 105% of
Inverter Amps (parameter 11) too
long. Continued operation at this
load level will cause an overload.
Reduce the load or duty cycle if possible.
If you do not want this condition to be reported as a fault,
change bit 13 in Fault Select 2 (parameter 22) to 0.
Refer to the Understanding the IT Inverter Protection
section in Appendix B for more information.

Inv Overload
VP, Flashing
red
Soft
Inverter (IT) overload. The
inverter current has been in
excess of 105% of Inverter Amps
(parameter 11) too long.
Reduce the load or duty cycle if possible.
If you do not want this condition to be reported as a fault,
change bit 15 in Fault Select 2 (parameter 22) to 0.

Warning
An inverter overtemperature is
pending. The inverter heatsink
temperature is approaching trip
level.
Check the cabinet filters, drive fans, and heatsinks.
Check the thermal sensor and sensor wiring (connector).
Reduce the load or duty cycle if possible.
Lower the value of PWM Frequency (parameter 10).
Check the roof fan direction of rotation (H frame only). It
should be counter- clockwise when viewed from the top.
If you do not want this condition to be reported as a
warning, change bit 1 in Warning Select 2
(parameter 23) to 0.

Inverter (IT) overload. The
inverter current has been in
excess of 105% of Inverter Amps
(parameter 11) too long.
Reduce the load or duty cycle if possible.

HW Malfunction
VP, Red 1
blink
Hard
A hardware malfunction was
detected on power up or reset.
When this condition occurs, the
drive coasts to a stop regardless
of the selected stop type.
Recycle the power. If the fault does not clear, replace the
main control board.
