Faults and Alarms
5.1 Fault messages
In the event of a failure, the inverter switches off and a fault code appears on the display. NOTE To reset the fault code, one of three method

s listed below can be used: 1. Cycle the power to the drive. 2. Press the button on the BOP or AOP. 3. Via Digital Input 3 (default setting) Fault messages are stored in parameter r0947 under their code number (e.g. F0003 = 3). The associated error value is found in parameter r0949. The value 0 is entered if a fault has no error value. It is furthermore possible to read out the point in time that a fault occurred (r0948) and the number of fault messages (P0952) stored in Parameter r0947.

F0001 OverCurrent STOP II
Quit Remove fault and reset fault memory by disconnecting the - drive converter from the line supply and powering-up again - Press the Fn key on the BOP or AOP - Acknowledge fault P2103, P2104 - P0952 (complete fault memory) Cause - Short circuit at the output - Earth faults - Excessively large motor - Defective end stage Diagnosis & Remedy Check the following: - Cable length limits must not be exceeded. - Motor cable and motor must have no short-circuits or earth faults - Motor parameters must match the motor in use - Value of stator resistance (P0350) must be correct - Motor must not be obstructed or overloaded - Increase the ramp time - Reduce the boost level - Connect a smaller motor (lower rating)

F0002 OverVoltage STOP II
Quit Refer to F0001 Cause - DC-link voltage (r0026) exceeds the overvoltage threshold (refer to parameter r0026) - Ground fault

NOTE Overvoltage can be caused either by too high main supply voltage or if motor is in regenerative mode. Regenerative mode can be cause by fast ramp downs or if the motor is driven from an active load.

F0003 UnderVoltage STOP II
Quit Refer to F0001 Cause - Main supply failed. - Shock load outside specified limits. Diagnosis & Remedy Check the following: - Supply voltage (P0210) must lie within limits indicated on rating plate. - Supply must not be susceptible to temporary failures or voltage reductions.

F0004 Inverter Over Temperature STOP II
Quit Refer to F0001 Cause - Ventilation inadequate - Ambient temperature is too high. - Actual drive converter temperature r0037 exceeds the overtemperature threshold (refer to P0292) Diagnosis & Remedy Check the following: - Fan must turn when inverter is running - Pulse frequency must be set to default value - Ambient temperature could be higher than specified for the inverter - Reduce the load and / or ensure adequate cooling Additional meaning for frame sizes FX and GX: - P949 = 1: Rectifier overtemperature

- P949 = 2: Ambient overtemperature - P949 = 3: EBOX overtemperature

F0005 Inverter I2T STOP II
Quit Refer to F0001 Cause - Inverter overloaded. - Duty cycle too demanding. - Motor power (P0307) exceeds inverter power capability (r0206). - 100 % overload reached (refer to utilization r0036 ) Diagnosis & Remedy Check the following: - Load duty cycle must lie within specified limits. - Motor power (P0307) must match inverter power (r0206)

F0011 Motor Over Temperature STOP II
Quit Refer to F0001 Cause Motor overloaded Diagnosis & Remedy Check the following: - Load duty cycle must be correct - Motor nominal overtemperatures (P0626-P0628) must be correct - Motor temperature warning level (P0604) must match - Voltage boost (increase) too high and / or frequency setpoint too low ? - Adapt the motor cooling to the application

F0012 Inverter temp. signal lost STOP I
Quit Refer to F0001 Cause Wire breakage of inverter temperature (heatsink) sensor

F0015 Motor temperature signal lost STOP II
Quit Refer to F0001 Cause Open or short circuit of motor temperature sensor. If signal loss is detected, temperature monitoring switches over to monitoring with the motor thermal model.

F0020 Mains Phase Missing STOP II
Quit

Refer to F0001 Cause Fault occurs if one of the three input phases are missed and the pulses are enabled and drive is loaded Diagnosis & Remedy check the input wiring of the mains phases

F0021 Earth fault STOP II
Quit Refer to F0001 Cause Fault occurs if the sum of the phase currents is higher than 5 % of the nominal inverter current. NOTE This fault only occurs on inverters that have 3 current sensors. Framesizes D to F

F0022 HW monitoring active STOP II
Quit Refer to F0001 Cause That hardware fault (P0947 = 22 and P0949 = 1) caused by the following events: (1) DC-link overcurrent = short circuit of IGBT (2) Short circuit of chopper (3) Earth fault (4) I/O board is not properly inserted. - Framesizes A to C (1),(2),(3),(4) - Framesizes D to E (1),(2),(4) - Framesize F (2),(4) Since all these faults are assigned to one signal on the power stack, it is not possible to establish which one actually occurred. The following faults (UCE and I2C) occur for frame size FX / GX only: - UCE failure was detected, when P0947 = 22 and fault value P0949 = 12 or 13 or 14, depending on UCE. - I2C bus read out error, when P0947 = 22 and fault value P0949 = 21 (the power has to be switched off/on). Diagnosis & Remedy First you must see if the fault is permanent (i.e. the inverter cannot be started without the fault occurring) or sporadic (occurs occasionally or in certain defined operating conditions). Permanent F0022 fault: - Check the I/O board. It has to be fully pressed home. - Is there an earth fault or short circuit on the output of the inverter or in an IGBT? Disconnecting the motor cables will establish which of these. In the case where the fault occurs permanently when all external wiring (apart from mains) is disconnected, then the unit almost certainly has a defect and should be repaired. Sporadic F0022 fault: This should be treated as "overcurrent". The following may cause the sporadic occurrence of F0022: - Sudden load changes or mechanical blockages.

- Very short ramp times. - If the Sensorless Vector Control is badly optimized. - If an incorrect braking resistor of too low a resistance is fitted.

5.2 Alarm Messages
Alarm messages are stored in parameter r2110 under their code number (e.g. A0503 = 503) and can be read out from there.

A0910 Vdc-max controller de-activated
Cause Vdc max controller has been de-activated, since controller is not capable of keeping DC-link voltage (r0026) within limits (refer to r0026 and P1240). - Occurs if main supply voltage (P0210) is permanently too high. - Occurs if motor is driven by an active load, causing motor to goes into regenerative mode. - Occurs at very high load inertias, when ramping down. Diagnosis & Remedy

Check the following: - Input voltage (P0210) must lie within range. - Load must be match.

A0911 Vdc-max controller active
Cause Vdc max controller is active; so ramp-down times will be increased automatically to keep DC-link voltage (r0026) within limits (refer to r0026 and P1240).

A0912 Vdc-min controller active
Cause - Vdc min controller will be activated if DC-link voltage (r0026) falls below minimum level (refer to r0026 and P1240). - The kinetic energy of the motor is used to buffer the DC-link voltage, thus causing deceleration of the drive! - So short mains failures do not necessarily lead to an undervoltage trip.

A0920 ADC parameters not set properly.
Cause ADC parameters should not be set to identical values, since this would produce illogical results. - Index 0: Parameter settings for output identical - Index 1: Parameter settings for input identical - Index 2: Parameter settings for input do not correspond to ADC type

A0921 DAC parameters not set properly.
Cause DAC parameters should not be set to identical values, since this would produce illogical results. - Index 0: Parameter settings for output identical - Index 1: Parameter settings for input identical - Index 2: Parameter settings for output do not correspond to DAC type

A0922 No load applied to inverter
Cause No Load is applied to the inverter. As a result, some functions may not work as under normal load conditions.

A0923 Both JOG Left and JOG Right are requested
Cause Both JOG right and JOG left (P1055/P1056) have been requested. This freezes the RFG output frequency at its current value. Diagnosis & Remedy Do not press JOG right and left simultaneously.
