Appendix C – Initializing the inverter
If it becomes necessary to initialize the inverter (i.e. reset the inverter to the factory standard settings or just
clearing the trip history register) you will have to do the following:
First refer to the nameplate to find out if the inverter is a European version (L100IP-####F E ) or an American
version (L100IP-####F U ).
Then set the correct national version under b 85 by entering the parameter 01 for the European version and
parameter 02 for the American version.
Use function b 84 to determine whether only the trip history register is to be cleared (parameter 00) or
whether the inverter is to be reset to the factory standard settings (parameter 01). Then you will have to
proceed as follows:
1) Simultaneously press the FUNC key and both direction (arrow) keys on the digital operator.
2) While holding down the mentioned keys press the STOP key for a short time and wait for about 3
seconds until the blinking message
d 00 is shown on the display.
3) Now release all keys again. The initializing phase that now begins will be complete as soon as the
display
00 appears (output frequency display).
4) Set the carrier frequency ( b 83 ) to acceptable value (maximum values, which are different for each type
of the inverter, are printed on back side of the terminal cover):
MAXIMUM ALLOWABLE VALUES FOR CARRIER FREQUENCY:
L100IP-004NFE……..5kHz L100IP-007HFE……..2kHz
L100IP-007NFE……..2kHz L100IP-015HFE……..5kHz
L100IP-015NFE……..5kHz L100IP-022HFE……..5kHz
L100IP-022NFE……..5kHz L100IP-040HFE……..2kHz
L100IP-055HFE……..2kHz
L100IP-075HFE……..2kHz
The inverter power supply must not be switched off before the initializing phase has been completed.
Furthermore it is important to know that inverter initializing cannot be carried out with the remote operator,
the copy unit, or the OPE-J operator being connected.
