Variable motors with CANopen

At the SPS IPC Drives 2016, Nanotec presents two series of its plug and drive motors: the PD2-C-IP with a flange size of 42 mm (Nema 17) and the PD4-E. Both are rated IP65 and available as a CANopen version.

Nanotec’s PD2-C-IP is a drive based on the PD2-C series but designed for harsh environmental conditions. The motors have the same features as the PD2-C series and are also available as DC motors or high-pole servos (steppers). By means of field-oriented control, based on an integrated encoder, both motor types are controlled the same way and are only distinguished by their working point (rated speed/rated torque).

Both motor types are available in a USB or CANopen version. In the CANopen version, the drive can be controlled by means of the standardized fieldbus profile CiA 402. All interfaces except for USB use M8 connectors. In the USB version, the motor can be parameterized and programmed via USB. In operation, the USB port is protected by a watertight cap and the motor runs on the basis of digital and analog input signals in combination with the stored program.

The PD4-E is based on the PD4-C motors but has more fieldbus interfaces (among them CANopen) and more options than the PD4-C.In addition to protection class IP65, PD4-E motors expand the concept of the PD4-C series to additionally include the following technical options: A high-pole servo (stepper) with 56 mm or 60 mm flange size and a holding torque of up to 3,5 Nm (such as PD4-C), or a brushless DC servo with a flange size of 56 mm and a rated power of up to 220 W. For the encoder, the options magnetic singleturn absolute encoder with 12-bit resolution, battery-free multiturn absolute encoder with 16-bit single-turn and 18-bit multiturn resolution, or input for additional external encoder (e.g. linear scale) are available.

A software is also available for the setup and programming of Nanotec’s motor controllers: Plug & Drive Studio. The controller can be accessed from a PC via a variety of fieldbuses (CANopen, Ethernet, Modbus). For setup, the object directory holding the controller configuration can be read and written via a table. Pre-defined filters enable the user to only display the parts of CiA 402 objects that pertain to a certain task, such as setup or a certain operating mode, i.e. the speed. Experienced users can configure the objects via an integrated command line. The entire communication can be recorded and played back later so that lengthy command sequences only need to be entered once during setup. To tune the controller parameters, an integrated oscilloscope displays up to eight objects simultaneously with a resolution of up to one millisecond.
