2 Features

The TMCM-351 is a powerful three axes bipolar stepper motor controller/driver board with encoder interface

for all three axes and a large number of general purpose digital and analog input/outputs. Several different

serial communication interfaces are available.

Electrical data

 Supply voltage: +24V DC nominal (28.5V DC max.)

 Motor current: up to 2.8A RMS per axis (programmable)

Stepper motor data

 two phase bipolar stepper motors with up to 2.8A RMS coil current (e.g. QSH5718 or QSH6018)

 optional incremental encoder interface (a/b/n), accepts differential or single ended input signals

Interfaces

 reference switch inputs per motor axis (6 altogether, internal pull-up resistors, +24V compatible)

 8 general purpose inputs (+24V compatible)

 8 general purpose outputs incl. two power outputs (all open-collector)

 1 shutdown input (enable/disable driver stage in hardware)

 dedicated analog inputs (programmable 3.3V/10V input range)

 SPI connector with three chip select signals for I/O extension

 Encoder interface (based on TMC423)

 RS232 interface

 RS485 interface

 CAN interface

 USB interface

Features

 High-efficient operation, low power-dissipation (TMC249 stepper driver with external MOSFETs)

 Dynamic current control

 Integrated Protection

 On the fly alteration of motor parameters (e.g. position, velocity, acceleration)

 Motion profile calculation in real-time (TMC428 motion controller)

 Each axis individually and independently programmable

 Supports up to 64 microsteps per fullstep

 Integrated stallGuard™ for motor stall detection (e.g. elimination of end switches)

 Closed-loop operation with TMCL™ possible (when using the optional incremental encoder interface)

Software

 TMCL™ remote (direct mode) or stand-alone operation (memory for 2048 TMCL™ commands)

 Fully supported by TMCL-IDE (PC based integrated development environment)

 Optional CANopen firmware
