OPENdrive OD700 is an EtherCAT compatible servodrive for brushless motors. A key feature is automatic recognition of connected motors and configuration through “ODM,” a browser executable on PC and on machine board. This feature makes the servo system easy to commission through the EtherCAT channel without modifying machine connections. ODM enables visualization and modification of drives and motor characterization parameters 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 axis behavior for better machine performance.
Six OPENdrive models are available with current ratings of 1, 3, 6, 12, 18 and 36 A in three sizes. Each model has internal sampling times (50 sec for the current loop and 100 µsec for velocity and position loops) for dynamic management. This also allows 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. OASI brushless motors, when coupled with the drives, provide high inertia and dynamic operation. All motors are equipped with thermal sensors and are available with an optional brake. They are available in 3,000, 4,000 and 6,000 rpm with a stall torque range of 0.2 to 66 Nm.
