Many factories still equip production lines with aging Sigma5 Yaskawa servo, spare parts out of stock and repair cost soaring. Replacing with latest Sigma7 becomes the most cost-effective renovation option. We explain wiring modification, parameter matching and debug notes, avoid wrong installation damage.
Original 400W SGMJV old models can directly upgrade to
SGM7J-04AFC6S servo set, only slight parameter modification required without mechanical flange modification.
Traditional 850W SGMGV Sigma5 users prefer switching to
SGM7A-10AFA61 1KW servo for higher overload capacity and longer service life.
All retrofit recommended servo kits including original
SGMGV-09ADC6C are available from our warehouse spot stock.
