MX300

MX300

Delta’s modular AC drive series for machines with many drives. One rectifier module feeds up to six inverter modules through a common DC bus — up to 15 axes in total. It saves cabinet width, returns the energy of braking axes to the bus and reduces the need for braking resistors.

Key parameters

  • Supply 1 × 230 V AC or 3 × 400 V AC
  • Rectifier modules 2.2 – 3.7 kW (230 V) and 7.5 – 18.5 kW (400 V)
  • Inverter modules 0.4 – 2.2 kW (230 V) and 0.4 – 7.5 kW (400 V), with 1, 2 or 3 axes
  • MX300-C: CANopen and Modbus RS-485; MX300-E: EtherCAT, EtherNet/IP, PROFINET
  • V/F and SVC; induction and permanent-magnet synchronous motors
  • Protection IP40

MX300

MX300 splits the drive into modules: a rectifier module at the input, inverter modules with one, two or three axes and a link module. The modules mount side by side on a common DC bus without separate power wiring.

MKM-DR3M option for 3 inverter modules 49 × 160 × 160 mm

Distinctive features

  • Common DC bus between the modules — energy from a braking axis feeds an accelerating one, the bus voltage is more stable and a braking resistor is often unnecessary
  • The modules mount side by side without separate power wiring
  • Connection to DIADesigner through the built-in Type-C port, no adapter needed
  • Braking resistor — optional, on terminals B1/B2 of the rectifier module (version B)
  • No built-in EMC filter — the MKM-EPRD plate is used

Applications

  • panel saws
  • wood, PVC, glass and metal processing
  • washing machines
  • conveyor belts
  • packaging machines
  • food and beverage
