Troubleshooting

Spare Parts

For Regulator card stock number and for other spare part information refer to manual 49'1327 "GV3000
Power Unit".

Test Equipment

Measuring the unit output variables by means of commercial measuring instruments involves
inaccuracies by virtue of the non sine-shaped output currents and voltages.
Refer also to Section 5 and 6 for notes regarding Test Equipment. Wherever possible, the internal
display should be used to measure the output variables.
More accurate measurement of the output voltage with an external instrument is only possible with a
fundamental voltmeter. The output current should be measured with a digital clip-on current measuring
instrument. The motor speed should be read directly from a hand held tachometer.

General Explanatory Notes

Each time the line supply is switched on, an internal self-diagnosis is activated. The period for this test is
approximately 10 seconds.
If an electronic equipment fault is detected during this test, a coded error message appears at the digital
display, e.g. 'F1' as power-up diagnostic fatal error. Turn power OFF and lockout or tag input power, and
check carefully all controller internal connections to the regulator card (e.g. if all flat ribbon cables are
secured in sockets) after having noticed an 'Fxx' displayed. Retry with power ON a new power-up
diagnostic procedure.
Rectifying a fatal error with 'Fxx' ('xx'= code number) displayed is in most cases only possible by
replacing the regulator board. In such a case, please contact your nearest ROCKWELL AUTOMATION
office and inform about the displayed error code.
Following successful completion of the self diagnostics, the 14 keypad LED's will show selected modes
and the digital data display shows '0'. The Keypad starts in Monitor mode lighting up that Monitor mode
LED last used before power loss.

Preparatory Instructions

It is recommended to perform a visual inspection of the equipment prior to rectifying a fault, and go
through the Start-up Check List in Sections 5 for V/Hz mode or Section 6 for Vector mode.
The equipment should be installed and connected electrically in accordance with the manual 49'1327
Section 3.
The controller unit should be operated only within the limits of service conditions listed in manual
49'1327 Section 2.
To locate a fault it is also possible to check the basic functions of the controller by operation from the
keypad (parameter P.000 at value 'LOCL' for LOCAL operation mode) with the motor disconnected.
If at REMOTE mode uses analogue input speed reference, be sure the regulator card jumper J4 for
selecting voltage or current reference signal is set correctly, as per manual 49'1327, Section 3.
A fault trip can be recognised by the relevant error code being shown in the four-digit keypad data
display. The output relay (being configured for 'FAULT ACTIVE', P.013) on the regulator card and its
contact outputs are activated in the event of a fault trip.
The display facilities in the 'Error Code Display' operating mode are described in the Section 3 'View
Fault Codes' and 'Access Error Log Time Stamp'.
Use the following Fault Code table to obtain information regarding rectifying faults if errors occur.
Further useful information can be obtained by contacting your nearest ROCKWELL AUTOMATION
office by phone, telex or fax.
