    APPENDIX A Appendix A Discrete Power Supply Recommendations If the XL_PSU is not being used individual ViX drives can be powered from transformer/bridge rectifier power supplies of the type shown in Figure A-1. This design suggests suitable component values for powering particular drive types, but can be adapted to power more than one drive provided component power ratings are not exceeded.
  • Page 125 118 VIX AE SERVO DRIVE USER GUIDE The size of transformer required for a servo drive installation depends very much on the application and on the maximum shaft power delivered by individual motors. It is worth noting that in a one-off or low volume application it is usually preferable to be slightly generous in sizing the transformer, rather than spend a great deal of engineering effort trying to calculate the minimum possible rating.
