Appendix Upgrading from the L300P Series The SJ300 series inverter is upwardly compatible with the L700 series inverter. Therefore, you can: - mount the control circuit terminal block board of the L300P series in the L700 series without removing the connected cables, - copy the parameter settings from the L300P series into the L700 series, and - use the option boards mounted in the L300P series for the L700 series without removing the connected...
Page 260 Appendix (2) Copying the parameter settings If you use an optional remote operator (SRW-OJ or SRW-OEX), you can copy (import) the parameter settings from the L300P series into the L700 series. Note, however, that you cannot copy the parameter settings from the L700 series to the L300P series because the L700 series has many new functions and additional parameters.
