CAUSE
Output current has exceeded internal
fault limit.
In addition to an actual overcurrent
situation, this warning may also be
caused by an earth fault or supply phase
loss.
Drive has detected load unbalance
typically due to earth fault in motor or
motor cable.
Short-circuit in motor cable(s) or motor.
The motor parameters are set incorrectly. Check the auxiliary code.
The drive is not dimensioned correctly.
Motor is operating in stall region because
of, for example, excessive load or
insufficient motor power.
Motor current is too high.
All three output phases are disconnected
from motor.
Installed extension module is not the
same as configured.
Cyclical communication between drive
and fieldbus adapter module A or
between PLC and fieldbus adapter
module A is lost.
Communication break in embedded
fieldbus (EFB) communication.
Control panel or PC tool selected as
active control location for drive has
ceased communicating.
Maintenance timer limit exceeded.
A fault is about to be auto reset.
Drive has received an emergency stop
(mode selection off2) command.
Drive has received an emergency stop
(mode selection off1 or off3) command.
The start delay is active and the drive will
start the motor after a predefined delay.
Run permissive is keeping the drive from
running the motor.
Start interlock 1 is keeping the drive from
starting.
Start interlock 2 is keeping the drive from
starting.
Check motor load.
Check acceleration times in parameter group 23 Speed reference ramp
(speed control) or 28 Frequency reference chain (frequency control).
Also check parameters 46.01 Speed scaling, 46.02 Frequency scaling
and 46.03 Torque scaling.
Check motor and motor cable (including phasing and delta/star
connection). Check for an earth fault in motor or motor cables by
measuring the insulation resistances of motor and motor cable. See
chapter Electrical installation, section Checking the insulation of the
assembly in the Hardware manual of the drive.
Check there are no contactors opening and closing in motor cable.
Check that the start-up data in parameter group 99 Motor data
corresponds to the motor rating plate.
Check that there are no power factor correction capacitors or surge
absorbers in motor cable.
Check there are no power factor correction capacitors or surge
absorbers in motor cable.
Check for an earth fault in motor or motor cables by measuring the
insulation resistances of motor and motor cable. See chapter Electrical
installation, section Checking the insulation of the assembly in the
Hardware manual of the drive. If an earth fault is found, fix or change the
motor cable and/or motor. If no earth fault can be detected, contact your
local Carrier representative.
Check motor and motor cable for cabling errors.
Check motor and motor cable (including phasing and delta/star
connection). Check for an earth fault in motor or motor cables by
measuring the insulation resistances of motor and motor cable. See
chapter Electrical installation, section Checking the insulation of the
assembly in the Hardware manual of the drive.
Check there are no power factor correction capacitors or surge
absorbers in motor cable.
Check the auxiliary code.
Check the settings of the motor configuration parameters in groups 98
and 99.
Check that the drive is sized correctly for the motor.
Check motor load and drive ratings. Check fault function parameters.
Check for overloaded motor.
Adjust the parameters used for the motor overload function
(35.51...35.53) and 35.55...35.56.
Check that switches between drive and motor are closed.
Check that all cables between drive and motor are connected and
secured. If no issue was detected and drive output was actually
connected to motor, contact Carrier.
Check that the installed extension module (shown by parameter 15.02
Detected extension module) is the same as selected by parameter
15.01 Extension module type.
Check status of fieldbus communication. See user documentation of
fieldbus interface.
Check settings of parameter groups 50 Fieldbus adapter (FBA), 51 FBA
A settings, 52 FBA A data in and 53 FBA A data out.
Check cable connections.
Check if communication master is able to communicate.
Check the status of the fieldbus master (online/offline/error etc.).
Check cable connections to the EIA-485/X5 terminals 29, 30 and 31 on
the control unit.
Check PC tool or control panelcconnection.
Check control panel connector.
Check mounting platform if being used. Disconnect and reconnect the
control panel.
Consider changing the cooling fan. Parameter 05.04 Fan on-time
counter shows the running time of the cooling fan.
Informative warning. See the settings in parameter group 31 Fault
functions.
Check that it is safe to continue operation. Then return emergency stop
push button to normal position. Restart drive.
If the emergency stop was unintentional, check the source selected by
parameter 21.05 Emergency stop source.
Check that it is safe to continue operation. Then return emergency stop
push button to normal position. Restart drive.
If the emergency stop was unintentional, check the source selected by
parameter 21.05 Emergency stop source.
Informative warning. See parameter 21.22 Start delay.
Check that it is safe to continue operation. Then return emergency stop
push button to normal position. Restart drive.
If the emergency stop was unintentional, check the source selected by
parameter 21.05 Emergency stop source.
Informative warning. See parameter 21.22 Start delay.
Check the setting of (and source selected by) parameter 20.40 Run
permissive.
Check the signal source selected for parameter 20.41 Start interlock 1.
Check the signal source selected for parameter 20.42 Start interlock 2.
