Sub-trip Reason
3 ExternalTrip (10.032) = 1
Recommended actions:
Check the value of ExternalTrip (10.032).
Select "Destinations" (or enter 12001) in Pr mm.000 and check for a parameter controlling ExternalTrip (10.032).
Ensure ExternalTrip (10.032) or UserTrip (10.038) (=6) is not being used by serial comms.
Trip FaN.f
Value 173
Short description Cooling fan failure
Fan failure
Recommended actions:
Check that the fan is fitted and connected correctly.
Contact the supplier of the drive to replace the fan.
Trip Fi.Ch
Value 247
Short description Configuration data within the drive has changed
Drive configuration file has changed in the power stage processor and so a power cycle is required.
Recommended actions:
Power cycle the drive
Trip FI.In
Value 237
Short description The power stage and control board firmware versions are not compatible
This trip is generated if the ww.xx parts of the User firmware version SoftwareVersion (11.029) do not match the ww.xx part of the power stage firmware PowerSoftwareVersion
(11.035).
Trip It.ac
Value 20
Short description Motor over temperature
This trip indicates a motor thermal overload based on the MotorRatedCurrent (05.007) and MotorThermalTimeConstant1 (04.015). MotorProtectionAccumulator
(04.019) displays the motor temperature as a percentage of the maximum value. The drive will trip on MotorTooHot when MotorProtectionAccumulator (04.019) gets to 100%.
Recommended actions:
Ensure the load is not jammed / sticking.
Check the load on the motor has not changed.
Tune the MotorRatedSpeed (05.008) (RFC-A mode only).
Ensure the motor rated current is correct.
Trip It.br
Value 19
Short description Brake resistor over temperature
This trip indicates that braking resistor overload has timed out. The value in BrakingResistorThermalAccumulator (10.039) is calculated using BrakingResistorRatedPower
(10.030), BrakingResistorThermalTimeConstant (10.031) and BrakingResistorResistance (10.061). This trip is initiated when BrakingResistorThermalAccumulator
(10.039) reaches 100%.
Recommended actions:
Ensure the values entered in BrakingResistorRatedPower (10.030), BrakingResistorThermalTimeConstant (10.031) and BrakingResistorResistance (10.061) are
correct.
If an external thermal protection device is being used and the braking resistor software overload protection is not required, set BrakingResistorRatedPower (10.030),
BrakingResistorThermalTimeConstant (10.031) and BrakingResistorResistance (10.061) to 0 to disable the trip.
Trip LF.Er
Value 90
Short description Communication link failure in the power stage (size 5 and above)
This trip is initiated if there is communications loss between processors in the power stage on sizes 5 and above. The reason for the trip can be identified by the sub-trip number.
Sub-trip Reason
1 Comms loss with the auxilairy power processor
1010 Comms loss with rectifier module
Recommended actions:
Hardware fault - contact the supplier of the drive.
