Part details & applications

The PANdrive PD-1140 family is a mechatronic solution including a 40mm flange stepper motor, a controller board and a SensOstep^™ encoder. It can be controlled via serial interface or operated in standalone mode. Power supply, external encoder, interface and I/Os can be connected with JST connectors.

With the advanced StallGuard2^™ the motor load can be detected with high resolution. The outstanding CoolStep^™ technology for sensorless load dependent current control allows efficient motor operation.

All you need to get started is a power supply and ADI Trinamic's free and easy to use TMCL-IDE. This graphical user interface allows quick setup and supports the use of commands in direct mode, monitors real-time behavior visualized in graphs, and logs and stores data.
