Stepper motor

Mechatronic solution with CANopen

The PD-1140 and PD-1160 from the Pandrive series by MEV (Germany) are a mechatronic solution including a flange stepper motor, a controller/driver board and a Sensostep encoder.

THE PD-1140 INCLUDES A 42-mm flange stepper motor and has been designed for a 0,20 Nm to 0,70 Nm maximum holding torque. It comes with a supply voltage of 9 VDC to 28 VDC. The PD-1160 includes a torque 57-mm or 60-mm flange stepper motor and has been designed for 0,55 Nm to 3,1 Nm holding torque. It comes with a supply voltage of 9 VDC to 51 VDC.

Both products feature CAN, USB, EIA-485 and ABN-Encoder interfaces and provide multi-purpose inputs and outputs. They can be controlled via those serial interfaces or operated in standalone mode. Power supply, external encoder, interface, and I/Os can be connected with JST connectors. The products are suitable for various decentralized applications.

Two different firmware options are available: CANopen offers several communication objects (COB), which enable system designers to transfer control information, to react to certain error conditions, or to influence and control the network behavior. The capability of a CANopen device can be evaluated by checking the existence of those CANopen object dictionary entries which describe the related communication behavior.

Beside the CANopen protocol there is the Trinamic Motion Control Language (TMCLTM), which also works with the other interfaces like USB or EIA-485. The TMCL-DIE, a Win-PC based software development environment can be downloaded for free. The protocol uses predefined commands like ‘move to position’ or ‘constant rotation’. All time critical operations, e.g. ramp calculation, are performed on board. The TMCLTM program can be stored in the on board EEPROM for stand-alone operation. The firmware of the module can be updated via the serial interface.
