DESCRIPTION AND RECOMMENDED CORRECTIVE ACTION
Output current is excessive. Check for excessive motor load, insufficient acceleration time (parameters 2202
ACCELER TIME 1, default 30 seconds), or faulty motor, motor cables or connections.
Intermediate circuit DC voltage is excessive. Check for static or transient over voltages in the input power supply,
insufficient deceleration time (parameters 2203 DECELER TIME 1, default 30 seconds), or undersized brake chopper
(if present).
Drive heat sink is overheated. Temperature is at or above 115_C (239_F). Check for fan failure, obstructions in the air
flow, dirt or dust coating on the heat sink, excessive ambient temperature, or excessive motor load.
Fault current. Check for short---circuit in the motor cable(s) or motor or supply disturbances.
Inverter overload condition. The drive output current exceeds the ratings.
Intermediate circuit DC voltage is not sufficient. Check for missing phase in the input power supply, blown fuse, or
under voltage on main circuit.
Analog input 1 loss. Analog input value is less than AI1 FLT LIMIT (3021). Check source and connection for analog
input and parameter settings for AI1 FLT LIMIT (3021) and 3001 AI<MIN FUNCTION.
Analog input 2 loss. Analog input value is less than AI2 FLT LIMIT (3022). Check source and connection for analog
input and parameter settings for AI2 FLT LIMIT (3022) and 3001 AI<MIN FUNCTION.
Motor is too hot, as estimated by the drive. Check for overloaded motor. Adjust the parameters used for the estimate
(3005 through 3009). Check the temperature sensors and Group 35 parameters.
Panel communication is lost and either drive is in local control mode (the control panel displays LOC), or drive is in
remote control mode (REM) and is parameterized to accept start/stop, direction or reference from the control panel.
To correct check the communication lines and connections. Check parameter 3002 PANEL COMM ERROR,
parameters in Group 10: Command Inputs and Group 11:Reference Select (if drive operation is REM).
The motor ID run was not completed successfully. Check motor connections.
Motor or process stall. Motor is operating in the stall region. Check for excessive load or insufficient motor power.
Check parameters 3010 through 3012.
Not used.
Digital input defined to report first external fault is active. See parameter 3003 EXTERNAL FAULT 1.
Digital input defined to report second external fault is active. See parameter 3004 EXTERNAL FAULT 2.
The load on the input power system is out of balance. Check for faults in the motor or motor cable. Verify that motor
cable does not exceed maximum specified length.
Motor load is lower than expected. Check for disconnected load. Check parameters 3013 UNDERLOAD FUNCTION
through 3015 UNDERLOAD CURVE.
Internal fault. The thermistor measuring the internal temperature of the drive is open or shorted. Contact Carrier.
Internal fault. A communication ---related problem has been detected between the OMIO and OINT boards. Contact
Carrier.
Internal fault. Low voltage condition detected on the OINT board. Contact Carrier.
Internal fault. Current measurement is out of range. Contact Carrier.
Ripple voltage in the DC link is too high. Check for missing main phase or blown fuse.
Not used.
Motor speed is greater than 120% of the larger (in magnitude) of 2001 MINIMUM SPEED or 2002 MAXIMUM SPEED
parameters. Check parameter settings for 2001 and 2002. Check adequacy of motor braking torque. Check
applicability of torque control. Check brake chopper and resistor.
Not used.
Internal fault. Configuration block drive ID is not valid.
Internal configuration file has an error. Contact Carrier.
Field bus communication has timed out. Check fault setup (3018 COMM FAULT FUNC and 3019 COMM FAULT
TIME). Check communication settings (Group 51 or 53 as appropriate). Check for poor connections and/or noise on
line.
Error in reading the configuration file for the field bus adapter.
Fault trip forced by the field bus. See the field bus reference literature.
Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
Fault code reserved for the EFB protocol application. The meaning is protocol dependent.
Fault in the motor circuit. One of the motor phases is lost. Check for motor fault, motor cable fault, thermal relay fault ,
or internal fault.
Error in power wiring suspected. Check that input power wired to drive output. Check for ground faults.
Error internal to the drive. Contact Carrier and report the error number.
Error internal to the drive. Contact Carrier and report the error number.
