Shared Bus - Infeed Module, Single Supply, Regenerative Regulated Bus

Consider a typical 3-axis gantry robot application in a shared bus configuration with the following:

 
  • Infeed Module
     
 Line rectifier power module with a regulated bus
 
 
  • X Axis
 Inverter module
 
 
  • Y Axis
 Inverter module
 
 
  • Z Axis
 Inverter module

  • System supply power

The total power the servo system draws or regenerates to the supply connection
   > 0 is supply
   < 0 is regenerative
 
  • Bus supply power

The supply power to the bus from the infeed module
   > 0 is supply
   < 0 is regenerative
 
  • Inverter power

The inverter power to and from the motor
   > 0 is motoring
   < 0 is generating
