The TMCM-078 can be operated with supply voltages of up to 75V and up to 7A RMS (9.8A peak) motor coil • supply voltage 15V to 75V DC SUPPORTED MOTORS • two-phase bipolar stepper motor with 0.7A to 7A RMS coil current INTERFACE • differential Step / Direction input currents. All major parameters can be set via DIP switches. Up to 256 micro-steps are supported for either high accuracy • driver disable input or high speed. The system features sensorless stall detection • input for reference switches (stallGuard™). The module is fully protected and comes with a • general purpose input / output stand-alone reference search feature. The housing is based on FEATURES an aluminium plate which is used as a heatsink. • up to 7A RMS coil current (9.8A peak) • optically isolated inputs for Step, Direction and Disable All inputs and outputs are accessible either via screw connec- • up to 256 micro-step resolution (adjustable) tors or by high density (2 mm) JST connectors. • adjustable standby current • stallGuard™ for reference search • full protection / diagnostics • RS485 host interface for optional use OTHER • pluggable screw terminal connectors for all signals with high density JST alternative • robust aluminum housing • RoHS compliant • size: 145 x 96 x 33 mm TMCM-078 RS-485 Step/Dir 15..75V DC Opto isolation programmable Motion Controller Driver TMC249 MOSFET Driver Stage Step Motor 5V Power Supply OR DE R C O DE D E SC R I P T IO N TMCM-078 1-axis step / direction driver module 75V, 7A Related products: USB-2-485 www.trinamic.com – for detailed information and datasheets 27
