The TMCM-1210 is a highly compact 20mm x 20mm single axis stepper motor controller and driver board with RS485 interface. It has been designed in order to be mounted on the rear side of a NEMA8 (20mm flange size) stepper motor and offers an integrated hall-sensor based encoder IC in addition to a reference switch input for easy homing / search of reference position. The module supports motor currents up to 0.6A RMS and supply voltages up to 24V DC nominal. It is available with standard TMCL firmware and supports stand-alone operation (TMCL programs with auto-start stored on-board) and remote control via RS485 interface.
Motion controller
• Motion profile calculation in hardware in real-time
• Motion controller supports linear and sixPoint™ ramps
• On the fly alteration of motor parameters (e.g. position, velocity, acceleration)
• High performance microcontroller (Cortex-M0+) for overall system control and serial communication protocol handling
Bipolar stepper motor driver
• Up to 256 microsteps per full step
• Highly integrated and highly-efficient operation
• Dynamic current control
• stallGuard2™ feature for stall detection
Interfaces
• RS485 2-wire communication interface
• Digital input IN0 (+24V compatible), can be used as reference switch or left and/or right stop switch input, also
On board hall sensor
• Absolute sensor within one motor rotation
• 12bit / 4096 steps / revolution max.
• Low-cost sensor - suitable for low velocity applications (few hundred rpm) - e.g. initial reference search (together with HOME sensor input) after power-up
Software
• TMCL™ remote (direct mode) and standalone operation with memory for up to 876 TMCL commands
• Fully supported by TMCL-IDE (PC based integrated development environment)
Electrical data
• Supply voltage: +7V… +30V DC
• Motor current: up to 0.7A RMS (programmable)
Mechanical data
• Board size: 20mm x 20mm, overall height 9mm max. (without mating connectors and cables)
• Mounting holes compatible with NEMA 8 stepper motors (for mounting the board to the rear side of a NEMA 8 stepper motor using two of the four existing screw)
