TMCM-1241

Stepper Motor Controller [&] Driver 3A/30V with USB/CAN/RS485, stealthChop™ (no noise)

The TMCM-1241 is a single axis motor controller/driver board for 2-phase bipolar stepper motors with up-to 3A RMS (4.3A peak) motor coil current. It supports linear ramps and unique SixPoint™ramps. It offers on-board sensOstep encoder and in addition, support for connection of external (incremental A/B) encoder.

For driver-only applications, the TMCM-1241 offers optically isolated Step/Direction inputs. When using the on-board motion controller the optically isolated inputs are used for connection of end-switches. The standard version of the TMCM-1241 offers one analog input (0..10V range), two digital inputs and one open-drain output (100mA load max.)

For communication in addition to USB (Micro-USB connector), RS485 and CAN serial interfaces are available. USB is intended mainly for 1rmware updates and parameter settings – supporting USB-powered operation (just the digital part) for easy data tranfer between PC and TMCM-1241 module. With CANopen 1rmware CANopen protocol is supported via the CAN interface.
