INFO
The TMCM-078 is a high power single axis step / direction step-
per motor driver. The TMCM-078 can be operated with supply
voltages of up to 75V and up to 7A RMS (9.8A peak) motor coil
currents. All major parameters can be set via DIP switches.
Up to 256 micro-steps are supported for either high accuracy
or high speed. The system features sensorless stall detection
(stallGuard™). The module is fully protected and comes with a
stand-alone reference search feature. The housing is based on
an aluminium plate which is used as a heatsink.
All inputs and outputs are accessible either via screw connec-
tors or by high density (2 mm) JST connectors.
