Troubleshooting and fault elimination

The five LEDs in the cover of the power feedback unit display the operating condition. For
easier visibility during service and first powering up similar LED's are placed on the con-
trol board.

Stop!

If the power feedback unit trips during retardation, it must not be reset until the end of the retar-
dation and until the DC-bus voltage has fallen to normal values.
To avoid any kind of problems you can block the impulse-release of the inverter by connecting
the collective-error-relay-contact of the power-feedback-unit with the corresponding connection
of the frequency inverter.

U

CE

-tripping:

The power feedback unit trips by the U

CE

-protective-circuitry, if the specific maximum

current of the device is exceeded. The principle of this protective-circuitry implies that for
a short time (less than one millisecond) the IGBT is stressed over its specification for nor-
mal operation. For a single case this means no problem for the power feedback unit. How-
ever, if the over current cut off arises often or even periodically, the high power semicon-
ductors will age very rapidly and fail premature.

The cause of periodical U

CE

cut offs may be over load, under voltage in the network, a de-

fective or oscillating controller, an oscillating reference input or a wrong design of the
plant.
