MODULE Module for Stepper Motors TMCM-1070 Hardware Manual Hardware Version V1.00 | Document Revision V1.10 • 2017-Oct-27 TMCM-1070 is an easy to use stepper motor driver module. The module is controlled via a step and direction interface. One configuration pin selects the current control mode between stealthChop™ for absolute silent motor control and spreadCycle™ for high speed. A TTL UART interface allows for more advanced configuration and permanent parameter storage via TMCL™-IDE.

TMCM-1070 Hardware Manual • Hardware Version V1.00 | Document Revision V1.10 • 2017-Oct-27 1 3 / 23 Features TMCM-1070 is an easy to use stepper driver unit with state of the art feature set. It is highly integrated and offers a convenient handling. TMCM-1070 can be used with a simple step and direction interface and can be configured using a TTL UART interface. stallGuard2 and coolStep can be configured via TTL UART interface and are disabled by default. 1.
TMCM-1070 Hardware Manual • Hardware Version V1.00 | Document Revision V1.10 • 2017-Oct-27 1.2 1.2.1 4 / 23 TRINAMIC’s Unique Features stealthChop™ stealthChop is an extremely quiet mode of operation for low and medium velocities. It is based on a voltage mode PWM. During standstill and at low velocities, the motor is absolutely noiseless. Thus, stealthChop operated stepper motor applications are very suitable for indoor or home use. The motor operates absolutely free of vibration at low velocities.
TMCM-1070 Hardware Manual • Hardware Version V1.00 | Document Revision V1.10 • 2017-Oct-27 1.3 5 / 23 stallGuard2 stallGuard2 is a high-precision sensorless load measurement using the back EMF of the motor coils. It can be used for stall detection as well as other uses at loads below those which stall the motor. The stallGuard2 measurement value changes linearly over a wide range of load, velocity, and current settings. At maximum motor load, the value reaches zero or is near zero.

There are two mounting holes for M3 screws for mounting the TMCM-1070 to a NEMA17 stepper motor (screw/thread length depends on motor size).
TMCM-1070 Hardware Manual • Hardware Version V1.00 | Document Revision V1.10 • 2017-Oct-27 3.2 8 / 23 Mounting Considerations TMCM-1070 is designed to be mountable on the back of a NEMA17 motor. Alternatively it can be mounted standalone. NOTICE 3.2.1 Thermal Considerations If not mounted to a motor take care for a proper cooling. The electronics have an overtemperature shutdown, nevertheless damage to electronics or system can be caused by excessive temperature.

TMCM-1070 Hardware Manual • Hardware Version V1.00 | Document Revision V1.10 • 2017-Oct-27 4.3 11 / 23 TTL UART Connection To connect via the TTL UART interface to a host PC, we suggest using a USB serial converter from TTL-UART (5V) to USB interface. Communication with the host PC, for example when using TRINAMIC’s TMCL-IDE, is done via the Virtual COM port installed by the converter driver. More information on the TMCL-IDE and the latest release can be found here: www.trinamic.
