ABSTRACT:
An energy management control apparatus for a molding machine that includes a first electrically-driven prime mover configured to drive at least a first molding machine device, and a second electrically-driven prime mover configured to drive at least a second molding machine device, includes a common DC link configured to provide DC energy to the first electrically-driven prime mover and to the second electrically-driven prime mover. A slave axis is configured to supply and absorb energy from to/from the common DC link. A machine controller is configured to (i) communicate with the first electrically-driven prime mover, the second electrically-driven prime mover, the common DC link, and the slave axis, (ii) cause the slave axis to supply energy to the common DC link in response to input from at least one of the first electrically-driven prime mover and the second electrically-driven prime mover, and (iii) cause the slave axis to absorb energy from the common DC link in response to input from at least one of the first electrically-driven prime mover and the second electrically-driven prime mover.
