Appendix A - 1 Upgrading from the SJ300 Series The SJ300 series inverter is upwardly compatibl e with the SJ700 series inverter . Therefore, you can: - mount the control circuit terminal block board of the SJ300 series in the SJ700 series without removing the connected cables, - copy the parameter settings from the SJ300 serie s into the SJ700 seri[...]

Appendix A - 2 (2) Copying the p arameter settings If you use an optional remote operator (SR W-O J or SRW -OEX), you can copy (import) the parameter 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 beca use the SJ700 series has many new f[...]
