Bonfiglioli’s experience brings you DGM - the new range of decentralized inverters for asynchronous motor control.
DGM is supplied with the gearmotor or separately, for wall or onboard assembly.
If the inverter is supplied with the gearmotor, the mechanical assembly, wiring and basic programming are performed by
Bonfiglioli, thus reducing installation times and operations required and limiting the risk of errors to a minimum.
Design and installation are faster compared to inverters installed in centralized switchboards.
• Application switchboard volume and cooling system reduction • Streamlined and simpler plant design. • Plant extensibility not affected by switchboard capacity. • No expensive shielded power cables required (otherwise necessary to meet the EMC standards).
CONTROL • Sensorless Vector Control. • PID operation with automatic speed control. • Automatic starting torque optimization • Configurable operation with typical quadratic curve • Motor-potentiometer function • Configurable quick restart
SAFETY AND PROTECTION • STO operating safety option embedded PLC • Motor protection I2t function • Locked shaft control • Start error assessment • Motor current limitation based on the settings • Embedded EMC filter in all versions
FIELD BUS • Fieldbus option (6 different fieldbuses) • Automatic scrolling compensation • Brake Chopper Option
PROGRAMMING • Cover embedded MMI option • Cover embedded Foil Keypad option • Wide range of configuration options, also thanks to the embedded PLC
DGM0 Single-phase only entry-level version with compact housing and reinforced plastic adapter • 0.25 … 0.75 kW DGM1 Single-phase version with a wide range of configuration options. • 0.37 … 1.1 kW DGM3 As for DGM1, but in the three-phase version • 0.55 … 22.0 kW
