Servo-drives for brushless motors for challenging applications introduced by OASI
CHICOPEE, Mass., 22 Jan. 2016. OASI-USA LLC in Chicopee, Mass., is introducing the OPENdrive OD700 servo-drives for brushless motors for precision and reliability in challenging applications.
These EtherCAT servo-drives integrate with OSAI's OPENcontrol family. OPENdrive OD700 is for metal working machine tools, plasma, oxy-fuel, water-jet, laser cutting, wood and stone machining systems.
A key feature is automatic recognition of connected motors and configuration through ODM, a powerful browser executable on PC and on machine board. This facilitates commissioning through the EtherCAT channel without modifying machine connections.
ODM enables visualization and modification of characterization parameters of drives and motors in addition to drive analysis through diagnostic graphics.
ODM also enables drive functions such as digital filters for the compensation of mechanical imperfections and the actuation time of the brake motor to synchronize it with axis motions. A multi-track oscilloscope allows execution of detailed analysis of axes behavior for the best machine performance.
Six OPENdrive models are available with current ratings of 1, 3, 6, 12, 18 and 36 amps in three sizes. Each model has internal sampling times of 50 seconds for the current loop and 100 microseconds for velocity and position loops to enable connection to an auxiliary encoder transducer for increased position accuracy control of the mechanical system.
All models have integrated SIL3 certified safety function controlling power to the drive during machine operation. Drives are equipped with two encoder inputs managing multiple primary and secondary transducers.
