Appendix Upgrading from the SJ300 Series The SJ300 series inverter is upwardly compatibl e with the SJ700 series inverter . Therefo re, you can: - mount the co ntrol ci rcuit terminal block board of the SJ300 serie s in the SJ700 seri es without removing the connected cables, - copy the p arameter settings from the SJ300 series int o the SJ700 seri[...]

Appendix A - 2 (2) Copying the p arameter settings If you use an optional remote operator (SR W-O J or SR W -OEX), you can copy (import) the p arameter settings from the SJ300 series into the S J700 se ries. Note, however , that you cannot copy the parameter settings from th e SJ700 series to the SJ 300 series because the S J700 series has many new[...]
