OPENDRIVE OD700 - ETHERCAT SERVO-DRIVEBack to list
Description: The new OPENdrive OD700 servo-drives for brushless motors, perfectly matches the OSAI OPENcontrol CNC product family, improving the dynamic performances of the system and simplifying configurability and commissioning. OD700 are provided with EtherCAT fieldbus, have compact mechanical dimensions and support a wide ranges of operating currents and power supply voltages. OD700 are the perfect solution for machines specific for vertical markets like Wood and Stone machining, Plasma, Oxy-fuel, Water-jet, Laser cutting and metal working machines tools. Six models are available with current ratings of 1A, 3A, 6A, 12A, 18A and 36A in three physical sizes. The internal sampling times - 50 microseconds for the current loop and 100 microseconds for velocity and position loops – allows to manage high dynamics while the possibility to connect an auxiliary encoder transducer allows to increase the position control accuracy of the mechanical system. All models have the STO (Safe Torque Off) safety function, a redundant input with SIL3 certification, “cutting” the power of the servo-drive. When the STO function is active the machine is in a safe condition allowing the operator to intervene without powering off the machine tool.
The drives, equipped with two encoder inputs, manage different types of primary and secondary transducers (SinCos 16/1024 Hiperface Single/Multi turn, Incremental SinCos 1Vpp with Hall probe, incremental ABZ con sonda Hall probe, Resolver, EndDat). The OSAI motors are high voltage sinusoidal brushless motors, with low inertia and high dynamics. They can also have an optional holding brake and include a thermal sensor. The position feedback is a Resolver or a SinCos 1024 pulses per revolution, also with Hiperface protocol. All motors have an IP65 protection level.
