Figure 19 - 600V AC PowerFlex 750-Series Mixed Architecture with PowerFlex 755TM Non-regenerative Supply
Diagram Notes:
• These DC bus voltage control methods are only applicable to 600V AC power systems. Do not use
PowerFlex 750-Series 600V AC frame 3...5 inverters on 690V AC power systems.
• AC and DC protection devices are required but not shown. See Appendix A
and the product technical
data for more information.
• Additional bus capacitance may be required. See DC Bus Capacitance Calculation Method on page 87
for more information.
• This diagram shows a solid ground AC source. High-resistance grounded AC sources can be used with
additional equipment.
• Regen Modules and Braking Modules aren’t available from Rockwell Automation. Contact third-party
suppliers for more information.
