Drives & Motors
The OSAI OS3CANopen servo drive product line for brushless motors has been specifically designed for applications in Industrial Automation such as: Robots, textile machines, packaging machines, palletisers and all other applications where the direct interface of the drive to CANopen is required.
The drive integrates the CANopen interface, implemented according to the DS402 profile, and can be driven in interpolation mode via real-time telegrams named PDO.The drive requires a three-phase power supply which can range between 230V (-10%) to 480V (+10%) without the need of a transformer. Four models are available in terms of RMS current (3A, 5A, 9A and 18A) in two physical sizes. The sampling times are 100 microseconds for the current loop and 200 microseconds for velocity and position loop.
It is also possible to connect an auxiliary encoder transducer to increase the position control accuracy, especially when the coupling between axis and motor is not rigid enough.
The drive speed reference command can also be via +/- 10V analogue signal when used in combination with SyncMotion with analogue interface. In this case, the drive transforms the resolver signal into an encoder signal compatible with the position input of the control unit; in this last case it is not possible to connect an external position transducer to the drive.
The drive parameters are setup using a configuration utility, which runs under the Windows operating system. This software utility also includes an interactive procedure which allows the system to be tuned using the integrated digital oscilloscope function, in order to achieve the best possible performance.
The OS3 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 and all motors have an IP65 protection level. The available standstill torques are from 0.6Nm up to 24Nm, with maximum speeds of 3000, 4000 and 6000 rpm. The motors can support high acceleration and deceleration up to 110.000rad/sec².
